Fire Hazard Conditions

As a safety provision, the operator can extend engine shutdown time for an additional 15 seconds by engaging
the ENGINE OVERRIDE switch, to allow moving the coach to a safe location. This may be done as many times
as necessary to safely bring the coach to a controlled stop.

In the event of fire, the green System OK LED will go out and the red FIRE LED will come on. The system will
force chemical fire suppressant through four spray nozzles located in the engine compartment. An audible buzzer
will sound continuously during fires. This alarm will operate until the Silence button is pushed. When the Silence
button has been pushed, the Silence Engaged LED will be illuminated.

Manual Operation

The manual function is used when a fault exists

that could inhibit auto/electrical actuation via the
control panel. During a fire emergency, the driver
must manually pull the disarming pin that retains
the actuator switch and push the button. The
manual fire button is located behind the lower,
LH Console on the left side of the driver’s seat.

Air Pressure - Warning

Individual analog pressure gauges are used to monitor the vehicle’s front (secondary) and rear (primary) air
brake systems. An LED indicator in each of the gauge illuminates and a warning alarm sounds if air pressure
drops below 70 psi (483 kPa). Warnings will remain on until air pressure rises above 95 psi (655 kPa).

WARNING
In the event of a low air warning, stop the vehicle at once and do not operate the vehicle
until the air loss is fixed and the low air alarm is canceled.

Do not operated the coach with air pressure below 100 psi in either gauges, as brake effec-
tiveness could be reduced resulting in an increased stopping distance.

Service Brakes (Emergency Operation)

This coach is equipped with a dual-circuit service brake system with separate reservoirs for rear and front brakes
to ensure that brakes are available if one circuit fails. If a low air pressure occurs in the primary service brake
supply circuit, secondary service brake air is routed to the emergency stand-by valve. Fully modulated primary
(rear) braking will be available through the drive axle brake chamber's emergency portion, along with the
secondary (front) service brakes.

Parking Brakes (Emergency Operation)

If the front and rear brake system air pressure falls
below approximately 40 ± 5 psi (276 ± 35 kPa), the
parking brake will automatically apply. An isolated
emergency release reservoir has enough air to
release the parking brake three times. Press and
hold the emergency parking brake release button
(LH console switch panel). The parking brake
springs will reapply as soon as the knob is
released.

Figure 17: Emergency Parking Brake Release

WARNING
The parking brake emergency release button allows the coach to be moved to safety if both
brake reservoirs are depleted and the parking brake has applied automatically. Do not use
this feature other than to move the coach to a safe parking location. Do not drive the coach
until the air loss problem is fixed and the brake reservoirs are fully charged.

Coach Air Service

A service fill/supply provision is located behind the curb-side rear service door and the front roadside service
compartment allows filling/ supplying the coach air system from an external source, provided the air system is
intact. The air service fill can also be used at the “WHOLE COACH AIR CONNECTION” port in the figure above.

Emergency Stops
If you must stop the coach because of a breakdown or an unsafe condition, ensure that it is safely parked. Pull
coach away from traffic, apply park brake, turn on hazard lights, and obtain and place reflector triangles in front
and behind the coach. Signal flares are provided in a cylindrical case above the reflector triangles case.

Figure 20: Reflector and Signal Flare Location

Safety Equipment
The safety reflector triangles and the flare are stored in the curb side service compartment the figure above. The
bottle jack, wheel wrench, wrench bar, and run-up block are located drag link area below the front junction box.

Figure 21: Roadside Tools

Hazard Signal System

The coach is equipped with a flashing signal system which flashes all directional signal lights simultaneously to
warn traffic in an emergency. The hazard warning switch is used to energize this signal system. A HAZARD
telltale light is illuminated and both turn indicator arrows flash when the system is operating.

The Hazard/Warning lights automatically activate when the passenger door opens, the wheelchair lift switch is in
the “ON” position or when reverse gear is selected. The lights extinguish when the passenger doors closes, the
wheelchair lift switch is in the “OFF” position and the transmission is not in reverse.

Interior Rear-View Mirrors

The interior rear-view mirror is mounted above the driver, it

can be manually adjusted up, down, or sideways. Adjust to
provide a clear view of the interior of the coach.

WARNING
Do not adjust the interior rear-view mirror while
the coach is moving. Stop the coach and apply
parking brake to adjust mirror.

Figure 67: Interior Rear-View Mirror

Exterior Rear-View Mirrors

The coach is equipped with power adjustable exterior heated mirrors with convex upper mirror surfaces for wide
angle viewing and larger full lower flat mirror surfaces. An additional convex spot-view mirror is mounted on the
curbside arm allows the viewing of the blind spot area directly in front of the coach. Mirror adjustment controller is
located on the LH console switch panel, and the heated mirror switch is located on the LH switch panel right
above the Ignition switch.

Adjust the mirrors so that the sidewall of the coach can just be seen in the inner portion of the mirror. This will
help determine the relationship of the coach to objects seen in the mirror.

Ensure that some portion of the mirrors can also be seen through the wiper sweep when they are in use.

Driver’s Seat Adjustment

The basic driver's seat can be manually adjusted for height, fore and aft positioning, setback tilt and seat cushion
pitch. After adjusting a manually operated seat, test by pushing forward and rearward on the seat. Make sure
seat does not move, and that the adjuster mechanisms have latched.

Other adjustments are manually actuated such as seat base forward and rearward movement, front seat cushion
tilt, setback adjustment, headrest adjustment and internal shock absorber adjustments.

WARNING
Do not attempt adjustment of the driver’s seat while the coach is in motion. The seat could
move suddenly and unexpectedly, causing the driver to lose control of the vehicle.

After making a seat adjustment, always test to ensure that the adjusters have latched.
Improperly latched seat adjusting mechanisms can impair driving capabilities and create an
unsafe operating condition. Report any seat mechanism locking problem immediately to
service personnel.

Pneumatic Lumbar Support Adjustment

NOTICE
This adjustment is important to attaining and maintaining positive lumbar back support.
Carefully make adjustments that provide the maximum support and driving comfort for your
specific physical structure.

A control panel, located on the right hand side of the

seat, contains three rocker-type switches controlling
pneumatic lumbar adjustment:

(A) Adjusts the upper lumbar pneumatic support

(B) Adjusts the mid lumbar pneumatic support

(C) Adjusts the lower lumbar pneumatic support.

(D) Adjusts the seat forward or rearward by pushing

the air slide release button. Use body momentum to
slide the seat either forward or rearward to the
desired position. Release the button to lock the
seat in position.

Figure 69: Driver’s Seat Controls

Backrest Inclination

Recline adjusting knobs are located at the right-hand and left-hand rear base of the seat back. Rotate the knobs
forward or rearward to adjust the recline angle of the seat back.

Seat Tilt

Seat tilt adjusting knobs are located on the right-hand and left-hand side of the seat cushion. Rotate the knobs
forward or rearward to adjust the tilt of the seat. Seat tilt is independent of seat height adjustment.

Seat Height Adjustment

The height adjusting knob is located on the left-hand front edge of the seat cushion. Rotate the knobs to adjust
the height of the seat.

Headrest Support

Adjust the headrest height by pulling up or pushing down on the top of the headrest. Position the headrest to the
desired height. Make certain the headrest locks into place after adjusting.

Final Adjustment Checks

After making any of the manually operated seat adjustments, test the seat by pushing forward and rearward.
Make sure it will not move and that the seat adjusters have securely latched. Any movement of the seat indicates
that at least on indexing pin has not engaged. An improperly latched seat mechanism could impair driver
capabilities. Report any seat adjustment or locking mechanism problems to service personnel immediately.

About Your Seat Belts

Seat belts are the single most effective safety device because they keep you connected to the vehicle so that you
can take advantage of many built-in safety features. They also help keep you from being ejected outside of your
seat. In addition, seat belts help protect you in almost every type of collision, including frontal impacts, side
impacts, rear impacts, and rollovers.

WARNING
Not wearing a seat belt properly increases the chance of serious injury or death in a
collision.

NOTICE
If the seat belt is extended too quickly, it will lock in place. If this happens, slightly retract
the seat belt, then extend it slowly.

Seat Belt Inspection

Inspect passenger and driver seat belts, buckles, latch plates, retractors, tethers, guide loops, and mounting
hardware for visible webbing wear or damage, including frays, cuts, burns, discolorations, abrasions, or any other
physical damage. The retractor should operate smoothly, and the belt buckles should latch easily. Also check for
loose or damaged parts that could keep the restraint system from operating properly. Keep sharp edges and
sharp objects away from the belts and other parts of the restraint system. Any belts that are questionable, do not
meet the above criteria, or were involved in a collision should be replaced regardless of mileage.

Seat Belt Cleaning

Belts should be kept clean and dry. Clean seat belts with mild soap and lukewarm water only, and avoid bleaching
or dying belts as this may weaken them.

NOTICE
After cleaning, make sure seat belt is completely dry before allowing it to retract.

WARNING
Not checking or maintaining seat belts can result in serious injury or death if the seat belts
do not work properly when needed. Check the seat belts regularly and have any problem
corrected as soon as possible.

1060576 75 February 2024

 D4520 Operator’s Manual

Proper Use of Seat Belts

All occupants should sit upright, well back in the seat, and remain in that position for the duration of the trip.
Slouching and leaning reduce the effectiveness of the belt.

Never place the shoulder part of a lap/should belt under your arm or behind your back. This could cause very
serious injuries in a collision.

CAUTION
Do not put any accessories on the seat belts. Devices intended to improve comfort or repo-
sition the shoulder part of a seat belt can reduce the protective capability and increase the
chance of serious injury in a collision.

NOTICE
Most states and all Canadian provinces and territories require drivers to wear seat belts.
The Seat Belt Tell Tale indicator will illuminate if the driver does not fasten their seat belt.
Following state and provincial regulations for driver’s and passenger’s seat belts. MCI
strongly recommends wearing them at all times to enhance your safety.

Fastening a Seat Belt

After adjusting a seat to the proper position and while

sitting upright and well back in the seat:

1. Pull the seat belt out slowly.

2. Insert the latch plate into the buckle, then tug on

the belt to make sure the belt is secure.

CAUTION
Make sure that the belt is not twisted or
not caught on anything.

3. Position the lap part of the belt as low as possible

across your hips, then pull up on the should part of
the belt so the lap part fits snugly.
Figure 70: Seat Belt Adjustment

4. Adjust to a snug fit by pulling the belt firmly across your lap toward the lap belt retractor so it can take up the
slack.

5. If necessary, pull up on the belt again to remove any slack, then check that the belt rests across the center of
your chest and over your shoulder.

WARNING
Improperly positioning the seat belts can cause serious injury or death in a collision. Make
sure all seat belts are properly positioned when in operation.

6. To unfasten the belt, push in the button in the center of the buckle. The retractor is designed to rewind the
belt automatically when the buckle is unlatched.

February 2024 76 1060576

 D4520 Operator’s Manual

CAUTION
Do not let the belt twist while it is rewinding into the retractor. The bulk of the twisted belt
may cause the retractor to jam so it will not rewind further. At the same time the retractor
may keep the belt from being pulled out.

If a belt should get jammed, you may be able to release it by working the belt in and out until the belt rewinds far
enough to unlock. If the belt remains jammed the seat belt system may not operate correctly and should be
replaced.

WARNING
No one should sit in a seat with an inoperative seat belt or one that does not appear to be
working correctly. Using a seat belt that is not working properly may not protect the
occupant in a collision. Have a technician to check any questionable belts as soon as
possible.

Seat Belts for Children

Follow state and provincial regulations for securing children passengers with a seatbelt.

Pregnant Women

If you are pregnant, the best way to protect yourself and your unborn child when driving or riding in a vehicle is to
always wear a seat belt and keep the lap part of the belt as low as possible across the hips. A doctor should also
be consulted for any specific recommendations.

Sleep Mode
If the operator does not turn the main battery disconnect switch to the OFF position, the electrical system will go
into “sleep mode” thirty (30) minutes after turning the ignition switch OFF. The operator can “wake” the electrical
system by hitting the entrance door switch, the hazard lights switch, or by turning on the Master Power / Ignition
switch.

Pre-Trip Inspection
The exterior lights and dash tell-tales automatically
activate for two (2) minutes, when the “Pre-Trip” button
on the Multi Function Display LCD touch screen is
pressed. The message “Pre-Trip Checking” will display
on the LCD screen for the duration of the two minutes
feature, unless the screen is pressed again or the park
brake is released.

Figure 71: MFD Pre-Trip Selection

NOTICE
The Pre-Trip test mode is useful to check proper operation of the multiplex outputs and the
exterior lights illumination. It doesn't test the functionality of the commands related to the
exterior lighting. For a complete testing, the directional signal operation, the headlights
operation and the brake lights operation have to be performed. Once these commands are
tested, activate the test mode to check the exterior lighting.

3. Press the Master Power / Ignition Switch to the ON (upper) position to enable all of the multiplex modules
and turn on the coach’s electrical system.

4. Ensure the transmission shift pad indicator is in NEUTRAL.

5. Wait for the CHECK ENGINE and STOP ENG tell-tale lights to extinguish.

6. Start the engine using the ENGINE START switch on the left-hand switch panel.

7. Check all gauges and tell-tale lamps for proper function.

8. Position the FAST IDLE switch to ON in order to build up air pressure.

9. Look and listen for any indications of system or equipment malfunction. Report any sign of trouble to service
personnel before operating the coach further.

CAUTION
Before starting the engine, ensure that fast idle feature is OFF, transmission is in Neutral,
and the parking is applied.

Do not start the engine when the engine warning lights stay on or do not come on
momentarily after turning on the ignition. Operating the engine under these circumstances
may cause engine damage.

1060576 79 February 2024

 D4520 Operator’s Manual

CAUTION
Do not engage the starter for longer than 15 seconds at a time. Allow starter motor to cool
before a second attempt. Continuous use of the starter without allowing a cooling period
may damage the starter motor.

CAUTION
Special precautions are necessary with turbocharged engines to avoid possible turbine
damage. After starting, run the engine at normal idle for two minutes to allow lubricating oil
to reach the turbocharger. Then run the engine at fast idle. Let oil pressure reach normal
operating range before driving.

Engine Warm-Up

After the initial starting and low idle engine operation, it is necessary to activate the fast idle for three minutes to
bring engine up to temperature, or to quickly fill the air system. Parking brakes should be kept applied during
initial warm-up, and must be on before the fast idle will operate. Observe gauges and telltale lamps frequently
during warm-up and subsequent operation. If abnormal conditions develop, stop engine immediately and
determine cause.

NOTICE
Fast idle function is interlocked to the park brake.

Stopping the Engine

1. Bring coach to a complete stop.

2. Place transmission in NEUTRAL and apply the parking brake.

3. Idle engine at low RPM for 30 seconds, then turn the ignition OFF.

CAUTION
Shutting down a turbo-charged engine directly from a high RPM condition may cause dam-
age to the turbocharger. Idling at a low RPM before shutting down the engine assures that
the turbine speed has dropped.

Engine Electronic System - Warning

Each engine installation is equipped with a notification system to warn the operator of an abnormal oil/coolant
level and/or temperature condition. Such conditions are notified by telltale lights and buzzer from the instrument
panel. Coaches have an automatic system to power-down and/or shutdown engine operation if any abnormal
conditions arise.

The automatic power-down or shutdown can be temporarily over-ridden to move the coach to a safe location.

If the engine has begun the 30-second power-down sequence, the following procedure can be used to keep the
coach in motion:

1. Activate the ENGINE SHUTDOWN OVERRIDE switch located on the left-hand console switch panel.

2. Continue coach travel until a safe location is found. Operate engine at lowest RPM possible while moving the
coach.

February 2024 80 1060576

 D4520 Operator’s Manual

If the engine has automatically shut down, the following procedure must be used to restart and move the coach:

1. Momentarily turn the ignition switch to the OFF position and back to ON again.

2. Press the ENGINE SHUTDOWN OVERRIDE switch and attempt to restart engine with the ENGINE START
switch.

3. Move the coach to a safe location. Operate the engine at lowest RPM possible while moving the coach.

Engine Brake

WARNING
The engine braking feature is meant to supplement, not replace the service brakes nor
intended to bring the vehicle to a stop. Engine brake is designed to reduce the speed of your
vehicle under a certain conditions.

WARNING
Before activating the engine brake, make sure that the coach is maintaining traction and
stability by using the natural retarding of the engine alone. If the retarding of the engine alone
causes any loss of traction, DO NOT attempt to use the engine brake until road conditions
improve.

The D45 CRT LE is equipped with auxiliary engine brakes that use the engine to aid in slowing and controlling the
coach. When activated, the engine brake alters the operation of the engine’s exhaust valves so that the engine
works as a power-absorbing air compressor.

Operation

There are two (2) levels of engine brake available to choose from and the control switch is located on the left-
hand switch panel. To enable engine brake, press the switch up for HI level and down for LOW. HI level will
provide more aggressive engine brake power than LOW. An Indicator (AUX) on the dash illuminates when the
system is active.

The operation of the engine brake is fully automatic once turned on. When the driver releases the throttle, the
engine brake will automatically apply. Once pressure is being applied to the throttle, the engine brake is
deactivated. To turn off the engine brake system, put the switch to the middle position and the indicator on the
instrumental panel will distinguished.

NOTICE
When cruise control is active, and
engine braking has not been turned
off by the rocker switch, if the coach
starts to exceed the cruise set speed
by a certain amount (ie. going
downhill), engine brakes will
automatically progressively engage
to reduce the amount of overspeed
that will occur. When the vehicle
speed falls back to set speed, engine
braking will stop, and normal cruise
operation will continue. No driver
interaction required.

Engine Oil Gauge

Normal readings at operating temperatures are 50-70

PSI (345-483 kPa) at 1,800 RPM. If the oil pressure
drops below a safe level during operation, the CHECK
ENGINE or STOP ENGINE tell-tale lights will
illuminate. This condition should cause the coach
engine to automatically shutdown.

Lubricating Oil Specification

Cummins Diesel X12 Engines have an oil capacity of

9.0 U.S. gallons (34 L)

Diesel engines require heavy-duty lubricating oils. The

only lubricating oil recommended for Cummins X12
diesel engines is CES 20086 and viscosity grade SAE
10W-30, API Classification CK-4.

Synthetic oils may be used in Cummins engines,

provided they are API licensed and meet the
performance and chemical requirements of non-
synthetic oils in the API category III and viscosity
grade SAE 10W-30. The use of synthetic oils does not
extend the oil drain interval recommended by
Cummins.

Cummins warranties.

Engine Coolant Temperature (Overheat)

The engine coolant temp. range varies between the different engines. If possible, avoid going to full throttle until
engine temp. reaches 140F (60C). The engine will come up to normal operating temperature shortly after driving.
A coolant temperature gauge displaying the operating temperature located on the MDF LCD screen.

If the engine becomes overheated during operation, the CHECK ENGINE or STOP ENGINE telltale lights will
illuminate. This condition should also cause the coach engine to derate (check engine) or automatically shutdown
(stop engine). If overheating occurs, check water level of engine cooling system as directed under Engine
Cooling System and look for other possible causes.

Transmission
The B500 series GEN VI is an electronically-controlled, hydraulic actuated, power shifting, six-speed torque
converter automatic transmission with lockup torque converter. This transmission controls all aspects of the shift
function once placed into the desired drive range. Shift range selections are made with the touch-pad module
located on the lower left-hand console.

A two-character digital display is located at the top of

automatic transmission shift selector. The left character of
the display, SELECT, designates N, R, or the highest gear
available of the selected forward range. The right character
of the display, MONITOR, designates the actual gear which
is being commanded and attained by the transmission
control module (TCM).

Two-character diagnostic codes can be accessed using the

touch pad on the shift selector.

The MODE button can be utilized to invoke a special

function that has been programmed into the TCM. A small
red light is illuminated on the MODE button when the
function is activated.

NOTICE
The gear selector should always be in the
NEUTRAL position when the coach is parked.

Figure 76: Allison Shift Selector

Shift Inhibit Logic

This system prevents the transmission from selecting a gear unless there is a full brake application (60 PSI), the
Low Entry mode is deactivated, and the kneeling feature is deactivated.

Shift Selection

The following is a brief description of the symbols used for gear range selection on the automatic transmission
shift selector:

• R - Reverse
• N - Neutral
• D - Drive: the highest forward gear will appear on the SELECT display. The transmission will shift to the
starting gear, on the MONITOR display.

During normal operation with DRIVE selected, the SELECT display shows the highest attainable forward range.
The MONITOR display shows the gear which has been commanded by the TCM (actual gear in which the
transmission is currently operating).

The UPSHIFT and DOWNSHIFT arrow buttons ( Δ and ∇ ) are used to select higher, (if not in DRIVE), or lower, if
not in 1), forward range.One press of the pushbutton changes the range selected by one range If the pushbutton
is held down continuously, the selected range will continue to change up or down until the button is released or
until the highest or lowest possible range of gears is selected.

Even though a lower range is selected, the transmission may not down-shift until coach speed is reduced, thus
preventing engine over speed in the lower range.

The UPSHIFT and DOWNSHIFT arrow buttons are not functional in REVERSE or in NEUTRAL.

February 2024 84 1060576

 D4520 Operator’s Manual

CAUTION
There is no PARK position on the shift selector.

ALWAYS apply the parking brake to hold the coach while unattended and place the shift
control selector in the N (NEUTRAL) position. Refer to “Service Brakes” and “Park Brake
Release” headings for the proper parking brake application and release procedure.

CAUTION
When shifting from NEUTRAL to DRIVE or REVERSE range, the engine should be at normal
idle speed. When the coach is parked, the transmission should always be in the N (NEU-
TRAL) position.

Tell-Tale Warning Light

The electronic control system is programmed to alert the driver when something is wrong by illuminating the
CHECK TRANS in the tell-tale cluster.

Illumination of the CHECK TRANS at any time after engine start (system check) indicates that a problem has
been detected. When a problem condition has been detected, the TCM / ECU will:

•Illuminate the CHECK TRANS tell-tale lamp

•Flash the display on the pushbutton shift selector

•Restrict shifting

•Register a diagnostic code

Generally, while the CHECK TRANS lamp is illuminated, the up-shifts and down-shifts will be restricted and
direction changes will not occur. The pushbutton selector should not respond to any operator shift requests while
the CHECK TRANS tell-tale lamp is on.

When the CHECK TRANS lamp is illuminated, the transmission will operate in the Limp Home mode with reduced
capabilities. The Limp Home feature will lockup the transmission in the current gear to enable continued coach
operation for a short time until it can be moved safely out of traffic. Advise service personnel immediately to
minimize the potential for damage to the transmission.

CAUTION
Do not attempt shutdown of engine or shift transmission until coach is safely parked. If shut
down and restart is attempted, the transmission would shift into NEUTRAL, which would
discontinue the Limp Home feature and leave the coach stranded until the fault is cleared.

Allison Diagnostic Code Retrieval

Diagnostic codes, displayed as two digit numbers, indicate a transmission malfunction. Diagnostic codes can be
accessed through the pushbutton shift selector. These codes are logged in the TCM/ECU with the most severe or
recent code listed first.

A maximum of five codes, identified as d1 to d5, can be listed at one time. As codes are added, the oldest non-
active codes are dropped from the list. If all codes are active, the code the lowest priority not included on the
severity list is dropped.

1060576 85 February 2024

With the selector in N, simultaneously press the Δ and ∇ buttons twice. Press and holde the MODE button for ten
seconds to clear both active indicators and in-active codes. Release the button to return to normal operation.

Allison Fluid Level Check

Fluid level diagnostic information, displayed as two-digit numbers, can be access through the pushbutton shift
selector. These checks should in no way take the placed of the manually conducted dipstick level check.

The coach must be parked on a level

surface with the transmission in NEUTRAL
and the park brake applied. The fluid level
check may be delayed until the following
conditions are met:

• The fluid temperature is above

140°F (60°C) and below 220°
(104°C)

• The transmission is in NEUTRAL

• The engine is at idle

• The transmission output shaft

has stopped.

• The coach has been stationary

for approximately two minutes,
allowing fluid to settle.
Figure 77: Transmission Oil Dipstick Location

February 2024 86 1060576

 D4520 Operator’s Manual

The pushbutton shift selector will indicate a delayed fluid level check by a flashing display under SELECT and a
digital countdown from 8 to 1 under MONITOR.

To access fluid level diagnostic information, simultaneously press the Δ and ∇ buttons to access the fluid level
display mode.

A correct fluid level is reported when an OL is displayed (OL indicates the Oil Level Check Mode), followed by
OK. The OK display indicates that the fluid level is within the correct fluid level zone.

NOTICE
The dipstick check may not agree exactly with sensor checks due to the oil level sensor
compensating for fluid temperature.

Low fluid level is reported when an OL is displayed by LO and a number. LO indicates a low fluid level, and the
number indicates quarts of fluid the transmission requires. OL LO 02 indicates that two additional quarts of fluid
should bring the level to the acceptable zone.

Confirm an electronically obtained low fluid condition by making a manual fluid level check.

High fluid level is reported when an OL is displayed, followed by HI and a number. HI indicates a high fluid level
and the number indicates quarts overfilled. OL HI 01 indicates one quart past the full level.

Invalid display conditions are reported when an OL is displayed, followed by a -- and a number. The displayed
number is a code, and would indicate improper condition for electronic check or a system malfunction. OL--70
would indicate that the oil sump temperature is too low.

NOTICE
The Invalid Display is activated when conditions do not allow the fluid level to be checked.
Review the following codes and their associated conditions to assist in quickly correcting
the condition.

Codes Descriptions

OL -- 0X Setting time too short

OL -- 50 Engine speed (RPM) too low

OL -- 59 Engine speed (RPM) too high

OL -- 65 Neutral (N) must be selected

OL -- 70 Sump oil temperature too low

OL -- 79 Sump oil temperature too high

OL -- 89 Output shaft rotation

OL -- 95 Sensor Failure

To exit the oil level display mode with the pushbutton shift selector, press any other button on the selector.

Lubricating Oil - Automatic Transmission

The transmission fluid used to apply the clutches and lubricate and cool the components must be maintained at
the proper level. If the fluid level is too low, the clutches will not receive adequate fluid supply and performance
will be affected. If the fluid level is too high, overheating may result from the fluid being churned and aerated.

1060576 87 February 2024

 D4520 Operator’s Manual

Brakes
This coach is equipped with air-operated service brakes
which are applied using the foot pedal to the left of the
accelerator pedal. The amount of pressure applied to the
pedal determines the extent and force of the brake
application.

Air system pressure must be at least 100 PSI (689 kPa)

before brakes can develop their full effectiveness. Observe
the air pressures indicated on the dual air gauge at frequent
intervals during coach operation.

NOTICE
“Fanning” or “pumping” the brake pedal is not
recommended. This practice reduces the
effectiveness of the brake system and
interferes with the ABS system. It also wastes
air and causes unnecessary wear on brake
parts.
Figure 78: Service Brake Pedal Location
CAUTION
Stop lights on the rear of the coach automatically illuminate when the brake pedal is
depressed. A tell-tale light on the dash illuminates when stop lights are activated.

Anti-Lock Brake System (ABS)

The ABS (Anti-Lock Brake System) minimizes the potential of brake lock-up in low traction road conditions or in
panic stop braking situations. The coach retains a greater degree of stability and ability to steer properly.

During braking, the ABS system automatically senses any impending wheel lock-up due to loss of traction. The
system monitors deceleration rates during braking and automatically pulses brake application pressures at each
wheel.

An ABS indicator light on the Multi Function Display tell-tale cluster tells the condition of the anti-lock brake
system. At coach starting, the indicator first flashes and goes out. If the indicator illuminates when the coach is
moving at road speed (above 5-7 MPH), the anti-lock brake system is malfunctioning and service is required. An
ABS malfunction automatically reverts the brake system to standard non-ABS operation.

CAUTION
Do not pump the brake pedal, this defeats the purpose of the ABS.

High Traction Road Conditions

The ABS system is not activated during normal brake applications on high traction, dry road surfaces. During
braking, apply a firm, positive brake pedal pressure.

Low Traction Road Conditions

Do not pump or fan the brakes in low traction road conditions. Apply firm, positive pedal pressure for the ABS
system to be most effective. The sensors and modulator valves cause the brakes to pulse and modulate at a very
rapid rate, sensing any wheel which is near lock-up because of less traction and which wheels have enough
traction.

February 2024 88 1060576

 D4520 Operator’s Manual

Panic Stop Braking Conditions

Do not pump or fan the brakes in panic stop braking conditions. Apply firm, continuous, heavy pedal pressure.
The brakes the pulse and modulate at a very rapid rate, sensing which wheels are near lock-up because of less
traction and which wheels have enough traction. Brake pressure automatically adjusts at each wheel. In this way,
traction is maintained between the road surface and tires, increasing the potential for stable, non-skid stops
maintaining steering control.

Releasing Service or Park Brakes

CAUTION
Use the following release procedure to free service or park brakes. Do not attempt to brake
the coach free with engine power if the brakes fail to release.

In the event of a normal service brake fails to release, reduce air pressure to below 75 ± 5 PSI (517 ± 34.5 kPa)
by pumping the brake pedal. Operate the engine until dual air gauge reads above 100 PSI. Make a normal
service brake application and then release it, or make a normal park brake application, release it, and then make
a service brake application and release it. One of these procedures should free the brakes.

Parking and Emergency Brakes

The coach is equipped with an air-operated parking brake control valve to release the spring applied park brakes
for parking the vehicle and for emergency braking function. The park brake control valve is located to the left of
the driver under the ignition switch panel. A guard over the valve prevents accidental release of the parking
brakes.

Operation of the system is as follows:

1. Stop the coach by firmly applying the service brake

pedal. Pull up on the park brake valve knob to set
the park brakes. Brakes will remain applied and
locked, even if the coach air pressure is lost.
Always apply parking brakes by pulling up on the
park brake valve knob before leaving the coach.

2. Put the transmission in neutral by firmly pushing

on the N pushbutton on the transmission touch
pad.

CAUTION
Do not apply the parking brakes until the
coach has come to a complete stop.

 D4520 Operator’s Manual

The parking brake is interlocked with, and affects the operation of several other coach components. The
relationship between these components and the park brake interlock are listed below:

• Kneeling Feature - Applying the park brake energizes the kneeling relay when the kneeling switch is
activated. Releasing the park brake de-energizes the kneeling relay and the coach returns to ride
height if in the kneeling mode.

• Wheelchair Ramp - The park brake is interlocked by the Low Entry Access key switch. Park brake
must be set for Low Entry Access key to enable the wheelchair system.

NOTICE
At coach speeds less than 2 MPH, the wheelchair park brake interlock is set.

Emergency Parking Brake Release

The emergency parking brake release valve is a manually operated valve. It is used for emergency park brake
release. The valve is spring loaded and remains in the upper position unless constant manual downward force is
applied to release the park brakes.

CAUTION
Fully apply the service brakes to ensure complete release of the park brake. If the park
brake fails to release, refer to the park and service brake release procedure titled “Releas-
ing Service Brakes”.

The wheelchair doors must be closed before the park brake will release.

Tag Axle Steering & Lock Function

The tag axle is designed to caster steer freely only at low forward speed, this will result in a shorter
turning radius and give you more maneuverability in tight spaces. If forward speed reaches above
15 mph, the tag axle will lock-up in a straight ahead position. If speed falls below 10 mph, the tag
axle will unlocked and caster steer freely again. The locking and unlocking is controlled by an
electronic multiplex system with the programmed speed and logic.

You can override the tag lock condition only at forward speed below 10 mph. This can be done via
activating the “Tag Lock” switch on the LH console, pressing on the “LOCK” position will override
the default condition and lock-up the tag axle, pressing on the “AUTO” position will put the system
back into default mode.

ATC/ABS (MUD SNOW & ABS DIAG) Switch

The Automatic Traction Control (ATC) system will intervene automatically limiting engine torque
and applying braking pressure to a spinning drive wheel transferring engine power to the other
drive wheel that has better traction. This feature is active only at speed below 25 mph.

If drive wheels begin to lose traction during acceleration, ATC will engage automatically to assist
the driver in accelerating the vehicle. The ATC telltale light will flash rapidly to let you know
whenever ATC is actively functioning.

Enabling the “MUD SNOW” mode allows greater engine power and more wheel spin during ATC
operation. It is recommended to turn on this feature when operating on soft road surfaces. The ATC
telltale light will flash slowly to remind you that this function has been selected, and will flash
rapidly whenever the ATC system is actually operating in the Mud/Snow mode. Always remember
to turn the Mud/Snow feature OFF when driving on a firm road surface. A new ignition cycle, or a
second depression of the Mud/Snow switch will turn this function off.

Press the “ABS DIAG” to retrieve ABS blink codes from the ABS telltale.

Electronic Stability Control

This coach equipped with a stability control system that features Electronic Stability Control (ESC) combined with
Roll Stability Control (RSC). ESC is a computerized technology that improves the safety of a vehicle's handling
by detecting and potentially preventing skids by automatically applying brakes to help steer the vehicle where the
driver wants to go.

ESC is automatic in that these systems become active when the system Electronic Control Unit (ECU) senses
conditions that could produce imminent roll or directional instabilities. Rapid lane changes or cornering at
excessive speed on dry or slippery surfaces can create the potential for spin-out or drift out, often before the
operator is aware. The ESC system uses a lateral accelerometer, a steer angle sensor in the steering column and
a yaw rate sensor to enhance the operator's control in these conditions.

WARNING
During an ESC system intervention, the vehicle automatically decelerates. The ESC system
can slow the vehicle with or without you applying the brake pedal, and even when you are
applying the throttle. Even with the ESC system equipped, the driver remains responsible
for ensuring vehicle stability during operation.

WARNING
In the case where a vehicle equipped with the ESC system pulls a trailer, the latter must be
equipped with ABS.

Wingman Fusion System

The Fusion system is an integrated combination of these features:

• Adaptive Cruise Control with Braking

• Collision Mitigation Technology (Enhanced)
• Lane Departure Warning (LDW)
• Traffic Signal Recognition (TSR)

Bendix Wingman Fusion combines radar, camera, and the vehicle’s brake system to deliver adaptive cruise
control with braking, enhanced collision mitigation, lane departure warning, and over speed alerts. Visual and/or
audible alerts are integrated into the vehicle’s dash display (Parker Multi-function Display).

Main Fusion System Components

The main components are the Bendix ESP EC-80 Controller, the Bendix Wingman FLR21 radar, and the Bendix
AutoVue FLC20 Camera. The system uses these components for Adaptive Cruise-control with Braking (ACB),
Collision Mitigation Technology (enhanced), Lane Departure Warning (LDW) and Traffic Sign Recognition (TSR).

The Bendix Wingman Fusion system also assists by giving audible and visual alerts, whether or not cruise control
is on.

WARNING
Bendix safety technologies complement safe driving practices. No commercial vehicle
safety technology replaces a skilled, alert driver exercising safe driving techniques and
proactive, comprehensive driver training. Responsibility for the safe operation of the
vehicle remains with the driver at all times.

Improper use of the Bendix Wingman Fusion system can result in a collision causing
property damage, serious injuries, or death.

The radar system only senses metallic objects. Non-metallic or limited metallic objects
such as people, animals, RVs, motorcycles, horse drawn buggies, logging vehicles, or
cross-traffic will not trigger the system.

Under no circumstances must the radar be removed or repositioned from the original
production line installation. The assembly should always be mounted in the original
OEM location. The radar cover cannot be painted or covered by license plate, decal, or
graphic film.

CAUTION
Vehicle equipment, including bumpers, deer guards, etc, must not infringe upon the
zone used by the radar sensor to emit and receive radar wave. Failure to comply with
this requirement will impair the function of the radar. Only vehicle OEM-approved
covers and/or cover panels may be installed in front of the radar.

Volume Control Audible Alerts

WARNING
Audible alerts are meant to warn the operators of a situation, volume levels must be
kept at a moderate decibel so it can be heard while the coach is in operation.

NOTICE
Volume won’t be completely muted, but it can be turned down if it is too loud. The volume is
reset to max level with every key on.

The volume control for Wingman Fusion can be adjusted either in drive or park mode, only collision mitigation
and braking warning alerts are not adjustable, they are fixed at a max volume.

Operation

• Press (touch) anywhere in the Wingman screen area and the

volume controls will appear.

• Adjust the volume by pressing (tapping) the “ + “ or “ - “ buttons

on the screen. The volume level will change and shown on the
screen as adjustments are being made.

• Volume controls will disappear after 2 seconds, or press the

Wingman screen area to force controls to disappear.

Adaptive Cruise Control with Braking (ACB)

Figure 86: System Intervention Zone

The adaptive cruise control with braking feature is an additional upgrade of ordinary cruise control. ACB is
automatically activated when cruise control is set, it helps maintain a constant vehicle speed and set following
interval behind a vehicle detected ahead of yours, without you having to keep your foot on the brake pedal or
accelerator.

Using the radar sensor mounted to the front of the vehicle – with a range of approximately 500 feet – the system
reacts to detected forward vehicles in the same lane, traveling in the same direction.

If the forward vehicle slows down below the your vehicle’s cruise control set speed, the system will de-throttle the
engine, progressively apply the engine retarder, and then apply the foundation brakes in an attempt to maintain a
set following interval behind the forward vehicle. If the forward vehicle accelerates away, the Bendix Wingman
ACB system will automatically accelerate your vehicle to the original cruise control set speed, and again maintain
a set following interval behind the forward vehicle.

Since the Bendix Wingman Fusion system operates

along with normal cruise control, all the typical features
built into cruise control work as usual. For example,
SET/COAST, RESUME/COAST, SET/ACCEL, and
RESUME/ACCEL are fully supported by the Bendix
Wingman Fusion system.

NOTICE
Do not use cruise control when driving
speed must constantly be adjusted, such
as in heavy traffic, or on icy, snow-
covered, slippery, or gravel roads.
Figure 87: Forward Vehicle Speed, Cruise Control Set
Speed, Object Detection, and Following Interval

February 2024 98 1060576

 D4520 Operator’s Manual

CAUTION
The ACB features should not be used in certain operating conditions including the
following: Inclement Weather/Low Visibility Situations, Dense Traffic, Sharp Curves and
Winding Roads, Entrance or Exit Ramps, Downhill Grades, Construction Zones, Off-
Road, Smaller Forward Vehicles.

Braking Overuse

To guard against foundation brake overuse by the adaptive

cruise control with braking feature of the Bendix Wingman
Fusion system, the frequency of foundation brake
interventions is monitored. If the system detects a situation
where the brakes are being applied too frequently by the
system in a given time period, the brake overuse alert will
activate. This is designed to help prevent overheating of the
brakes, which may lead to brake fade and reduced vehicle
braking capability. In this situation, the Brake Overuse will
alert the operator.

• The intervention cancels cruise control. Figure 88: ACB Overuse Warning

• After a Brake Overuse Alert, for a period of time (typically 20 minutes), the Bendix Wingman Fusion
system will not use the foundation brakes when intervening. The system will be limited to de-throttling
the engine and applying the engine retarder.

NOTICE
In all cases, the driver still has the ability to apply the foundation brakes if necessary. The
driver should take care since overheated brakes may reduce the vehicle’s braking capability.
• The time period for this mode is measured from the time the Brake Overuse Alert was activated and
lasts approximately 20 minutes.

• The system will set a Diagnostic Trouble Code (DTC) and Wingman Braking will be disabled until the
next ignition cycle.

NOTICE
The operator will continue to receive all three alerts (Following Distance, Impact, and
Stationary Object).

WARNING
The Bendix Wingman Fusion system provides a warning when the system is intervening
and using the foundation brakes excessively. Overuse of the foundation brakes can lead
to the brakes overheating and a potential loss of braking performance caused by brake
fade. Using cruise control on downhill grades will cause this alert to be activated.

CAUTION
Cruise control should NOT be used on downhill grades. Approach grades as you would nor-
mally, with the appropriate gear selected and at a safe speed.

1060576 99 February 2024

 D4520 Operator’s Manual

Collision Mitigation Technology (CMT)

The Bendix Wingman Fusion system’s collision mitigation

technology is designed to be ready to alert the driver to detectable
objects in front of your vehicle (whether or not cruise control is set)
and react to the presence of stationary/moving vehicles in the lane
ahead. Collision mitigation interventions provide the driver with an
alert before an intervention occurs.

These alerts will change as the interval between the two vehicles
(or object) decreases alerting the operator of the impending hazard.
As the interval closes, the system will automatically intervene and
slow the vehicle in three ways in the following order, reduce throttle,
engage retarder, and apply foundation brakes.
Figure 89: Wingman Braking Message

The driver must immediately act to potentially avoid, or lessen the severity of, a collision.

If a collision is likely to occur, and the collision mitigation feature activates the foundation brakes, the tone of the
alert will typically change and the display will be as shown above. The driver must immediately act to potentially
avoid, or lessen the severity of, a collision.

Stationary Vehicle Braking (SVB)

The system uses BOTH radar and camera data to confirm the vehicle ahead. With an activation speed above 15
mph, here is how this dynamic feature works: When the large, stationary, metallic object in a vehicle’s lane of
travel is definitively identified as a licensed motorized vehicle, the driver is notified up to 3.5 seconds before
impact. If the driver does not take action to address the potential impact that caused the alert, Wingman Fusion
can automatically engage the brakes to assist the driver in reducing the severity of or potentially avoiding a
collision with the stationary vehicle.

If the system cannot definitively identify the stationary object as a licensed motorized vehicle, the driver will get
up to 3.0 seconds of alert to address the situation ahead; no automatic braking will be applied. Stationary Vehicle
Braking is most useful when approaching a line of stopped traffic or a stalled vehicle that is not immediately
recognized by the driver. Without the automatic alert and braking, it may be too late to avoid impact. As always,
responsibility for the safe operation of the vehicle remains with the driver at all times.

CAUTION
The Fusion system is ready to alert the operator whenever the vehicle is moving above
(15) mph [24 kph]. The driver should be especially careful when approaching certain
types of vehicles or objects. The Fusion system radar may not be able to detect vehicles
with limited metal surfaces such as recreational vehicles, horse-drawn buggies,
motorcycles, logging trailers, etc.). NOTE: Entering a curve may reduce the alert time.

WARNING
Any audible and/or visual alert by the system means that your vehicle is too close to the
vehicle ahead and the driver must immediately act to potentially avoid, or lessen the
severity of, a collision.

CAUTION
The driver should inspect the radar and camera mounting brackets regularly and keep
the windshield and bumper locations clear of any mud, snow, ice build-up, or other
obstructions. The installation of aftermarket deer guards, bumper guards, snow plows
or similar potential obstructions is not recommended, and could impair the operation of
the radar.

 D4520 Operator’s Manual

Lane Departure Warning (LDW)

The Bendix Wingman Fusion system uses the Forward Looking Camera to monitor the visible lane markings on
the road and when an unexpected lane change takes place – a lane change without an activated turn signal – and
alert (visual and audible warnings) the driver to make a correction. Tired, distracted, or inattentive drivers are
alerted and can take remedial actions. The LDW system is enabled above 37 mph / 60 kph.

Figure 90: Lane Detected

Figure 91: Lane Departure Warning (Left) Figure 92: Lane Departure Warning (Right)

NOTICE
The LDW may not detect all lane markings or lane departures; accuracy will vary based on
weather, speed, and lane marker condition. When it fails to detect lanes, the LDW system will
temporarily be inactive. It is always your responsibility to safely operate the vehicle and avoid
collisions.

WARNING
The Bendix Wingman Fusion system has the ability to warn the driver if the vehicle is
not tracking in the intended roadway path. In most vehicle applications the LDW system
is enabled above 37 mph. The driver should immediately correct the vehicle tracking
and maintain the correct position in the lane.

1060576 101 February 2024

 D4520 Operator’s Manual

The operator may disabled LDW momentary by turning on the “LDW DISABLE” switch located on the left hand
console. This is typically used when driving through construction zones where false alerts may exist continuously.
Each time the switch is activated, LDW will be inactive for 15 minutes. The system will automatically enable itself
after 15 minutes, or pressing the switch again will instantly enable LDW.

WARNING
Due to the inherent limitations of
image recognition technology,
camera-based safety technology —
on rare occasions — may not be
able to detect or may misinterpret
lane markings. At these times,
alerts may not occur, or erroneous
alerts may occur.

WARNING
Whenever re-installing or replacing
a camera - for example, after a
windshield is replaced - the
recommended position for the
vehicle must be used. Failure to
install the camera in the correct
position can results in system
Diagnostic Trouble Codes being set,
and system performance
degradation.

NOTICE
MAINTENANCE - In normal use, the
Bendix FLC20 Camera needs only a
clean, properly maintained windshield
to ensure a clear view of the road
ahead. Protect the camera lens
whenever the inside of the windshield
is being cleaned.

Figure 93: Lane Departure Warning Disabled

WARNING
The Bendix Wingman Fusion system has the ability to warn the driver if the vehicle’s
speed exceeds the posted legal limits. The Overspeed Alert is enabled when the vehicle
is traveling greater than 5mph / 8 kph from the posted limit. The driver should
immediately reduce speed to the posted legal limit.

February 2024 102 1060576

 D4520 Operator’s Manual

Traffic Sign Recognition

The Bendix Wingman Fusion system has the ability to assist the driver by recognizing US and Canadian speed
limit signs. This allows the system to display the current posted speed limit and alert the driver with audible and
visual on the dash display when over speed thresholds are detected.

Figure 94: Speed Limit Sign Registered Figure 95: Over Speed Alert

When the vehicle exceeds the posted speed limit by 5 mph / 8 kph, an audible alert will sound to alert the driver.
If the vehicle speed exceeds 10 mph /16 kph over the posted speed limit, an audible alert signals the driver to
slow down and a one-second de-throttle of the engine will occur.

Overuse alert activated and Traffic Sign Recognition (TSR) will be disabled if: 10 alerts of speed over the limit
(10mph over) is registered.

Figure 96: Excessive Over Speed Alert

Alerts and Warnings

The Bendix Wingman Fusion system operates differently compared to other cruise control/forward collision
warning systems. It is important for YOU to fully understand the system’s features, especially the driver alerts
and warnings.

Three important warnings provided by the Bendix Wingman Fusion system are the Following Distance Alert
(FDA), Collision Mitigation Alert (CMA), and Stationary Object Alert (SOA) on MCI Drive Scene display. The
operator will be alerted by any of the three warnings, whether or not the cruise control is activated.

WARNING
Any audible and/or visual alert by the system means that your vehicle is too close to the
vehicle ahead and the driver must immediately act to potentially avoid, or lessen the
severity of a collision.

1060576 103 February 2024

 D4520 Operator’s Manual

Following Distance Alerts (FDA)

FDAs are generated through the system using vehicle speed, forward vehicle speed, distance, and driving
scenario. These provide the operator with distance alerts (audible and visual) for the given situation. If the
following distance continues to decrease, the audible alerts will become progressively faster. The three levels of
FDAs provided are Level 1, Level 2, and Level 3. There are also three level of the following distance adjustment
that the operator can choose from. Please see “Following Distance Adjustment”.

Figure 97: Level 3 alert with forward vehicle speed and

following distance in seconds with single beep per sec-
ond. Note: The value of the following distance in second
is only an example and not a representation of an actual
operation.

Figure 98: Level 2 alert with forward vehicle speed and

following distance in seconds with double beep per sec-
ond. Note: The value of the following distance in second
is only an example and not a representation of an actual
operation.

Figure 99: Level 1 alert with forward vehicle speed and

following distance in seconds with continuous beeping.
Note: The value of the following distance in second is
only an example and not a representation of an actual
operation.

CAUTION
These alerts indicate that the interval time between your vehicle and the detected
forward vehicle ahead is less than one and a half (1.5) seconds and decreasing. Once
the audible alert is heard, the operator should increase the distance between their
vehicle and the vehicle ahead until the audible stops.

WARNING
The FDA is ready to alert the driver whenever the interval time between your vehicle and
the detected forward vehicle is less than 1.5 seconds and decreasing. Once the audible
alert is given, the driver should increase the distance between his/her vehicle and the
vehicle ahead until the audible alert stops. The FDA is ready to alert the driver whenever
the vehicle is moving above 5 mph/ 8 kph.

Following Distance Adjustment

The following distance toward the vehicle ahead of you can be adjusted if the default is not desired. Adjustment
is only achievable if the coach is stationary, transmission in neutral, and park brake applied.

Figure 100: Following Distance Settings

Operation

• Press the Menu button on the top left of the screen to get into the sub-menu

• Press the “Following Distance” button to get into the settings screen

• To change the following distance, press the “ + “ or “ - “ button to select FAR, SHORT, or SHORTEST.
The default settings is set to NORMAL.

• Press the “Saved” button to apply the changes.

NOTICE
Following distance in seconds is calculated based on the current speed of the Bendix
Wingman Fusion system-equipped vehicle, and the distance, in feet, away from the selected
forward vehicle. For instance, if the selected forward vehicle is 88 feet (27 m) from the bumper
of the Bendix Wingman Fusion system-equipped truck, and the Bendix Wingman Fusion
system-equipped truck is traveling 60 mph / 97 kph, then the following distance in seconds
would be 1.0 seconds because a truck traveling 60 mph / 97 kph can travel 88 feet (27 m) in
one (1) second.

 D4520 Operator’s Manual

Stationary Object Alert

Stationary Object Alert (SOA) is an alert given to the driver when the radar detects a sizable, non-moving metallic
object in the vehicle's path of travel. To reduce the number of false detections, such as bridges and overhead
signs, a set of filters are put in place so the SOA will not warn on every stationary object.

WARNING
Stationary Object Alert – The Bendix Wingman
Fusion system will give up to a three (3) second
alert to the driver when approaching a detected,
sizable, metallic (radar-reflective), stationary
object in your lane of travel. This alert indicates
that a collision with a stationary object is likely
and the driver must immediately act to potentially
avoid, or lessen the severity of, a collision.

Figure 101: Stationary Object Detected

CAUTION
SOA is ready to alert whenever the speed is above 10mph/16kph. The operator should
be especially careful when approaching certain types of vehicles or objects. The Fusion
system radar may not be able to detect objects with limited metal surfaces (such as

Impact Alert

The Impact Alert uses a combination of distance to the vehicle

ahead, plus high relative velocity, to decide when to issue a loud
solid tone, as well as a visual indicator to the operator.

When the Impact Alert activates, the operator must immediately act
to potentially avoid, or lessen the severity of, a collision. If a collision
is likely to occur, and the collision mitigation feature activates the
foundation brakes, the tone of the alert will typically change and the
display will be as shown below. The driver must immediately act to
potentially avoid, or lessen the severity of, a collision.

Bendix Safety Information

Bendix Wingman Fusion system, under proper conditions, will automatically activate the vehicle brakes if the
system determines an impact with a forward vehicle is likely to happen. Operating in cruise control is not required
for this automatic braking feature.

Safe Vehicle Operation Considerations:

CAUTION
The Adaptive Cruise Control feature should not be used in certain operating conditions
included in the following shown in the figure below:

Safe Operation of the vehicle is ultimately the

responsibility of the driver.

• The driver should never rely on the ACB or the

CMT feature to completely bring the vehicle to
a stop.

• The driver should always be attentive to

passing or stopping vehicles to avoid a
collision.

• The driver should be fully aware of his or her

surroundings and be ready to apply the brakes
before the system engages the brakes.

• The driver should be attentive to stationary

objects or stopped vehicles in the roadway.

WARNING
Bendix safety technologies complement
safe driving practices. No commercial
vehicle safety technology replaces a
skilled, alert driver exercising safe
driving techniques and proactive,
comprehensive driver training.
Responsibility for the safe operation of
the vehicle remains with the driver at all
times.

WARNING
The driver is always responsible for the
control and safe operation of the vehicle
at all times. The Bendix® Wingman®
Fusion™ system does not replace the
need for a skilled, alert professional
driver, reacting appropriately and in a
timely manner, and using safe driving
practices.

Diesel Fuel System

There are fuel filler neck doors located on each side of the
coach and they are equipped with key lock. Unlock the door
and remove one side filler cap only to refuel.

When servicing any of the diesel engine installations, refer to

the applicable manufacturer's Diesel Engine Service Manual.
Fuel system components which require periodic maintenance
include the engine air cleaner and fuel filters. Care must be
taken when filling the fuel tank to prevent entry of dirt and
water.

WARNING
Do not smoke or produce an open flame near or
while handling fuel.
Figure 106: Filler Neck Door Locations

Diesel Fuel Specification

Engines must comply with EPA mandated low emission guidelines by using ULSD (ultra low sulfur diesel) fuel.
Failure to use ULSD fuel will result in component damage.

Diesel Fuel Contamination

The most common form of diesel fuel contamination is water. Water can be introduced to the fuel supply through
poor maintenance (loose or open fuel tank cap), a contaminated fuel supply, or condensation.

Use care in the storage and handling of diesel fuel to prevent contamination by dirt and water. Condensation is
particularly prevalent on units which stand idle for long periods of time. Ambient temperature changes cause
condensation in partially filled fuel tanks. Fuel system is equipped with water sensor, service is required if “Water
in Fuel” telltale illuminates,

Fuel Pro Fuel Filter

The Fuel Pro fuel filter extends filter change intervals and features a clear cover that provides visual identification
of the fuel level. When the fuel level reaches the change filter line on the filter cartridge, the element should be
replaced at the next scheduled maintenance interval. Fuel filters should be replaced as a set.

Diesel Exhaust Fluid System

The DEF (Diesel Exhaust Fluid) tank is separate from the diesel tank, located at the rear curb side of the diesel
fuel tank. Unlock the DEF filler cap door and remove the blue color filler cap to refuel.

Figure 107: Diesel Exhaust Fluid Filler Location

Diesel Exhaust Fluid (DEF) Specification

DEF must meet ISO standard 22241-1.f.

CAUTION
DO NOT put anything but DEF in the DEF tank (blue cap).

Use only API (American Petroleum Institute) or DIN certified Diesel Exhaust Fluid. This
ensures compliance with ISO 22241. Improper fluids or contaminated DEF may lead to high
nitrogen oxide emissions and damage the SCR system. Contaminated SCR systems should
be service at an authorized dealer.

Do not use DEF beyond its expiration date or if it has been stored in conditions over 86°F
(30°C) for extended periods of time. This may cause degradation to the DEF.

Filling DEF Reservoir (General)

Refill the DEF Reservoir in a well ventilated area. Ammonia vapors have been known to escape when taking the
cap off of the fluid containing apparatus

Always wipe down the filler cap and adapter before refilling the DEF reservoir to help prevent contamination. Do
not power wash the reservoir assembly.

CAUTION
Do NOT pour any fluid/liquid into the Diesel Exhaust Fluid reservoir that is not Diesel
Exhaust Fluid. The DEF reservoir is easily identified by its blue cap. Introducing any fluid/
liquid that is not DEF can cause damage to the engine and/or the SCR system.

Visually inspect DEF gauge on instrument panel daily. If level is low, DEF must be added. Locate the filler cap
access door on the coach curbside next to the fuel filler door, remove blue cap, and fill DEF tank. If DEF is
spilled, contain spill and absorb with a noncombustible absorbent such as sand. If DEF is spilled on coach, rinse
with water.

February 2024 110 1060576

 D4520 Operator’s Manual

NOTICE
To avoid potential fault conditions flagged by the system, is important to fill the DEF tank
completely, however, DO NOT overfill the tank. Several fault conditions can be corrected by
simply keeping the tank full. Never operate the vehicle with the DEF tank cap removed. If a
non-DEF substance is accidentally introduced into the tank, the catalyst will recognize the
contamination and illuminate the DEF dash telltale. If the level of contamination is too high,
the coach may require servicing.

CAUTION
Do NOT overfill the DEF tank, especially while in colder climates. DEF will expand approxi-
mately 10–15% of its standard room temperature volume when completely frozen, and will
cause damage to the tank. The recommended fill volume for exposure to temperatures at or
below 12°F (-11°C) is approximately 75% of the total volume at auto shutoff. These 75% lev-
els can be ensured by checking the output data given by the level sender. Due to the level
sender limits, (to ensure a reliable reading) turn vehicle off and then restart, allowing a few
minutes for the sender to adjust its reading if the level seems inaccurate.

NOTICE
If the DEF tank is not filled and is allowed to go empty, the coach speed will be limited to 5
mph. Once filled, normal operation will resume.

Filling DEF Reservoir (Cold Weather)

CAUTION
During cold temperature filling, manually stop filling the reservoir before auto-shut off lev-
els. Do NOT overfill the DEF reservoir assembly, especially while in colder climates. DEF
will expand approximately 10–15% of its standard room temperature volume when com-
pletely frozen, and will cause damage to the reservoir assembly if it has been overfilled as
well as potential mixing of DEF and coolant.

If the reservoir is overfilled and freezes, the expansion of frozen DEF will cause catastrophic damage to the DEF
reservoir system and/or vehicle SCR system. The recommended fill volume for vehicles that may be subjected to
temperatures at or below 12°F (-11°C) is approximately 75% of the total volume at auto-shutoff. These 75%
levels can be ensured by checking the output data given by the level sender.

CAUTION
Make sure that the cap and adapter are clean prior to cap removal and filling to help prevent
contamination. Do NOT overfill with DEF. This could cause spillage and/ or overfill, which
can cause damage to the reservoir and/or vehicle. Clean any spilled DEF immediately with
fresh water to prevent corrosion to the system or vehicle components. Do not put DEF in
the fuel tank, or any fluid other than DEF in the DEF reservoir. This can cause engine dam-
age and/or damage to the SCR unit.

Filling the DEF reservoir with a fill station nozzle is similar to filling a tank with a normal fuel pump. Insert the DEF
station nozzle into the fill port and fill with DEF until the nozzle automatically shuts off.

1060576 111 February 2024

 D4520 Operator’s Manual

NOTICE
The magnetic interface in the DEF reservoir allows filling at all approved DEF fill stations.
The interface is hidden within the cap adapter and allows the locking mechanism of certain
station pumps to be opened, allowing the DEF to flow unhindered.

Insert fill nozzle as far as possible into the fill port adapter to ensure proper auto-shutoff levels. Fill with DEF until
the nozzle automatically shuts off. Do NOT overfill, top-off, or try to fill the reservoir any further after the nozzle
has automatically shut off as this may cause issues with DEF expansion during cold weather conditions. During
cold temperature filling, manually stop station filling the reservoir before auto-shutoff levels. During regular
station filling, the fill nozzle will automatically shut off slightly below the fill port.

DEF Bottle Filling

CAUTION
Make sure that the cap and adapter are clean prior to cap removal to help prevent contami-
nation. DO NOT reuse empty DEF bottle container or fluid. DO NOT store DEF container in
the vehicle because leaking DEF could cause damage to the interior and/or release ammo-
nia vapors.

The following applies to select DEF bottle filling apparatuses. Always consult the instructions on or included with
the bottle.

NOTICE
Bottle filling can still be used to fill the reservoir, regardless of a magnetic interface. The
possession or absence of a magnetic interface on the reservoir assembly will have no effect
on bottle filling.

Insert bottle spout fully into fill port adapter and fill slowly to prevent overfilling. Stop filling when level is near the
auto-shutoff level achieved when station filling (slightly below the fill port). Only use bottle filling when necessary.

DEF Cap

CAUTION
Make sure that the cap and adapter are clean prior to cap removal and filling to help prevent
contamination.

The cap on the DEF reservoir is a vented cap. When pressure reaches 4 psig, it is designed to release pressure
by venting to the atmosphere or to the tank. The DEF fill cap has an internal filter which cleans vacuum vented air
and prevents debris from entering the reservoir when it vents to the tank. If there are vacuum issues with the
reservoir, check the cap to make sure it is still functioning correctly and not damaged, otherwise, contact an SCR
systems dealer. To check the fill cap, remove the DEF hoses and plug the DEF out/suction port to prevent any
leakage. Set up testing so that a vacuum is applied to the return/throttle line. The resulting venting should be
over 0.5 SCFH at 10 in. (254 mm) of water.

DEF Cap Cleaning

Clean cap periodically to remove crystallization buildup. If vacuum is present when removing cap, clean cap as
soon as possible.

Wipe of cap and adapter and remove cap. Place cap in a bucket of water and allow to soak for five minutes.
While cap is submerged, shake vigorously to break up and loosen any residual DEF. Remove cap from water,
shake off excess water, and dry thoroughly with compressed air. Replace cap.

Exhaust Aftertreatment System

MCI coaches are equipped with a diesel particulate filter (DPF) and a regeneration system which work together to
reduce particulate emissions. The manual Regeneration switch is located at the curbside rear service door.

On MCI coaches there are three regeneration modes:

•Passive Regeneration - Normal engine operation provides sufficient exhaust temperature for
regeneration to occur with no noticeable effects to the driver.

•Active Regeneration - Normal engine operation does not provide sufficient exhaust temperature for
passive regeneration to occur. Regeneration system raises the exhaust temperature for regeneration to
occur.

•Stationary Regeneration - Normal operation of the engine will not allow for passive or active
regeneration to occur. The operator must initiate a regeneration with the remote switch.

WARNING
To avoid serious personal injury or property damage, ensure that no persons or objects are
at or within two feet of the exhaust outlet at any time during a regeneration. Ensure that
exhaust and outlet are clear of any trash, grasses, or other vegetation or debris.

Use extreme caution during a stationary regeneration, as exhaust gas tail pipe outlet tem-
peratures can exceed 900 degrees F (482 degrees C). Stationary regenerations are to be per-
formed outdoors only.

DO NOT leave the coach unattended during a stationary regeneration.

DO NOT perform inside a garage or maintenance facility.

DO NOT attach an exhaust extraction hose to the exhaust outlet.

MCI coaches are equipped with two specific tell-tales for the DPF regeneration system:

• Regeneration Tell-Tale Lamp (DPF) - Tell-tale illuminates when a regeneration is required. Tell-tale is
OFF during regeneration.

• High Exhaust Temperature Tell-Tale Lamp (HET) - Tell-tale illuminates when the coach is moving at a
low speed and the exhaust outlet temperature exceeds the predetermined level.

Figure 108: Regeneration Telltales

Engine Specific Regeneration Strategy

Before a parked or stationary regeneration can occur, these requirements must be met:

• The DPF tell-tale lamp is illuminated (solid or flashing)

• Vehicle speed is 0 MPH

1060576 113 February 2024

 D4520 Operator’s Manual

• Locate the transmission push-button selector. While making a service brake application, cycle the
push-button shift selector by pressing Drive or Reverse, then Neutral

• The HVAC system is OFF

• The engine is running at idle speed (not fast idle)

• Park brake is applied

• Service brake is released

• The exhaust and outlet are clear of any trash, grasses, or debris

Press the REGEN START switch, hold for five seconds to initiate regeneration and center LED illuminates,
whereas LH LED is illuminated when a stationary regen is required and RH LED is illuminated when stationary
regen is active. Press the DPF REGEN STOP switch and hold to stop regeneration at anytime. Pressing DEF
REGEN STOP button stops regeneration and illuminates all 3 green LED.

Stationary Regeneration Operation

DPF tell-tale lamp will illuminate for 1 sec and turn OFF for the duration of regeneration, Engine RPM will rise to
950-1050 RPM, HET tell-tale lamp will illuminate after approximately, 3 minutes indicating high exhaust
temperature during the regeneration and remain on until after the exhaust is below the predetermined temp.
Duration of the regeneration is 20-60 minutes depending on the level of soot in the DPF. When the regeneration
is completed, all telltales will be OFF, engine RPM will return to idle.

A stationary regeneration can be interrupted by disabling one or more of the Stationary Regen requirements, or,
press the Regen STOP switch and hold for 5 seconds, or, Turning OFF the ignition switch.

An active regeneration can be interrupted by applying the park brake, or placing the transmission in DRIVE or
REVERSE gear.

WARNING
During stationary regeneration, exhaust temperature may reach up to 1200°F (650°C) at the
particulate filter. Before initiating stationary regeneration, make sure that the DPF outlet
diffuser is clear of objects and that no one is working near the DPF outlet diffuser.

Hot surfaces. Keep yourself clear of all hot Aftertreatment Device components, particularly
during and after active or stationary regeneration. Hot surfaces can cause serious burns.

Electronic Engine Control System

This system controls the combustion process of the engine through timing and fuel metering relative to internal/
external sensor readings. The system continually monitors information from the electronic transmission control
system to achieve more fuel efficient shifting.

Various gauges are provided to show engine oil pressure and coolant temperatures, however, the electronic
control systems generally monitor conditions that could result in damage to the engine or that are dangerous to
coach operation. If during operation the system detects a serious condition, (such as loss of water or oil), it will
alert the driver via the telltale warning lights. Audible alarms may also be installed to alert driver of serious
problems.

The system can be programmed to sequentially reduce power and shut engine down in case of serious engine
problems. An EMERGENCY OVERRIDE switch is provided to override the automatic engine shutdown system
and will allow engine to run for an additional 30 seconds so that coach may be moved to safe parking area. Use
the switch as often as necessary.

System Air Fill Connection

The system air fill connections
consists of a standard quick
disconnect fitting and a one-way
check valve that allow for filling of the
entire air system. Compressed air that
is added through this fitting enters the
system upstream from the cooling coil
and air dryer and is therefore dried
and filtered before entering the
remainder of the air system. The
system air fill provision is located at
the rear of the engine compartment on
the curbside, inside the service door.

Figure 149: Rear Air Fill & Air Supply

WARNING
The emergency air fill is to be used only in emergency cases on a disabled coach.

February 2024 140 1060576

 D4520 Operator’s Manual

Emergency Air Fill Provisions

The emergency air fill provisions consist of

standard quick disconnect fittings, each with its
own one-way check valve, that allow for filling of
the primary and secondary air reservoirs and
the park brake system. Compressed air that is
added through these fittings enters the system
at the supply ports of the two-way check valve
(park brake valve supply) and is therefore not
dried or filtered before entering the service
brake reservoirs and park brake system.
Because of the potential for contaminated air
being introduced into the coach air system when
using these provisions, they should be used
only in emergency situations. The emergency
air fill provisions are located on the left hand
front side service compartment under the front
junction box.

Tire Specifications
Recommended Tire Inflation Pressures

Ride characteristics and tire wear are affected by tire inflation. MCI recommends that the inflations shown on the
certification plate be followed for that size tire. Inflation pressures for tires other than those shown may be found
on the chart below.

NOTICE
The tires listed below meet GHG regulations as LRR tires. It is the owner’s responsibility for
tire maintenance.

Replacement Tires and Tire Inflation Chart (9.00” Rim)

Always replace the tires with the same rating, size, and the same or better rolling resist coefficient (CRR).
