Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001697601
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 SR 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 performed by
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 the SR 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 har-
ness connectors.

POWER WINDOW OPERATION
 Power window system is operable during the retained power operation timer after turning ignition switch ON
and OFF.
 Main power window and door lock/unlock switch can open/close all windows.
 Front & rear power window switches can open/close the corresponding windows.
POWER WINDOW AUTO-OPERATION (FRONT DRIVER SIDE)
 AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch turns
to AUTO.
 Encoder continues detecting the movement of power window motor and transmits to main power window
and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
 Main power window and door lock/unlock switch reads the changes of encoder signal and stops AUTO oper-
ation when door glass is at fully opened/closed position.
 Power window motor is operable in case encoder is malfunctioning.
RETAINED POWER OPERATION
 Retained power operation is an additional power supply function that enables power window system to oper-
ate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions  Front door CLOSE (door switch OFF)→OPEN (door switch ON).
 When ignition switch is ON.
 When timer time passes (45 seconds).
POWER WINDOW LOCK
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock
switch is ON. This inhibits power window switch operation except with the main power window and door lock/
unlock switch.
ANTI-PINCH OPERATION (FRONT DRIVER SIDE)
 Pinch foreign material in the door glass during AUTO-UP operation,and it is the anti-pinch function that low-
ers the door glass 150 mm (5.9 in.) or 2 seconds when detected.
 Encoder continues detecting the movement of power window motor and transmits to main power window
and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
 Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
 Power window switch controls to lower the window glass for 150 mm (5.9 in.) or 2 seconds after it detects
encoder pulse signal frequency change.
OPERATION CONDITION
 When door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the door
glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower.
