 PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” AFS0027G

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING: D
● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer. E
● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section. BR
● Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for Battery Service AFS0026R

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the H
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
I
Precautions for Brake System AFS0007W

● Recommended fluid is brake fluid “DOT 3”.

● Never reuse drained brake fluid. J
● Be careful not to splash brake fluid on painted areas.
● To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
● Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system. K
● Use flare nut wrench when removing and installing brake tube.
● When installing brake piping, be sure to check torque.
L
● Before working, turn the ignition switch OFF and disconnect the
connectors for the control unit or the battery negative terminal.
● Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal M
occurs at very low mileage.
Refer to BR-30, "BRAKE BURNISHING PROCEDURE" .
WARNING:
● Clean brake pads and shoes with a waste cloth, then wipe SBR686C
with a dust collector.
