The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
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
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. D
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING: E
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
F
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”. G
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors. H
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation. I
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing ADP
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.

• By associating Intelligent Key and automatic drive positioner system, the unlock operation of Intelligent Key
or driver side door request switch performs memory function and entry/exit assist function.
• Registration of Intelligent Key interlock function can register a different key ID to the driver seat control unit, B
one by one, for memory switch 1 and 2. A total of 2 key IDs can be registered.
• When ignition switch is OFF (steering lock unit status)*, and door unlock operation is performed using Intelli-
gent Key or driver side door request switch, driver seat automatically adjusts to a driving position other than
seat sliding. Seat sliding and steering column tilt perform return operation and are set to standby status. C
• In standby status, when ignition switch is operated from OFF to ACC, return operation sets seat sliding and
steering column tilt to a registered position.
*: With steering lock models D
NOTE:
• When another key ID is newly registered to a key switch to which a key ID is already registered, the previ-
ously registered key ID is overwritten and becomes unusable.
E
• When starter signal turns ON during return operation, the operation is interrupted, starter signal turns from
ON to OFF, and operation restarts.
OPERATION PROCEDURE F
1. Unlock driver door by Intelligent Key or driver side door request switch.
2. Operation other than memory function of seat sliding is performed. Seat sliding and steering column tilt
perform exit assist operation. G

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
