PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS00001
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
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.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
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.
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.
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.
Precautions for Battery ServiceNIS00002
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
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for WorkNIS00003
After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.
Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

OUTLINE
Functions available by operating the door lock and unlock switches on driver's door and pas-
senger's door
With the locking operation of door lock and unlock switch, door lock actuators of driver's and passenger's
doors are locked.
With the unlocking operation of door lock and unlock switch, door lock actuators of driver's and passen-
ger's doors are unlocked.
Functions available by operating the key cylinder switch
With the locking operation of door key cylinder, door lock actuators of all doors are locked.
When door key cylinder is unlocked, door lock actuator (driver side) is unlocked.
When door key cylinder is unlocked for the second time within 5 seconds after the first unlock operation,
door lock actuators on driver's and passenger's doors are unlocked.
Unlock mode can be changed by using CONSULT-III “WORK SUPPORT” mode in “DOOR LOCK-UNLOCK
SET”.
Refer to BL-35, "
WORK SUPPORT" .
Key reminder door system
When door lock and unlock switch is operated to lock doors with ignition key put in key cylinder and driver's
and passenger's door open, driver and passenger door lock actuators are locked and then unlocked.
