PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS0009B
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.
Service NoticeNIS0009C
When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.
Apply sealing compound where necessary when installing parts.
When applying sealing compound, be careful that the sealing compound does not protrude from parts.
When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
Precautions for Battery ServiceNIS0009D
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 WorkNIS0009E
When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-
nent with a shop cloth or vinyl tape to protect it.
Protect the removed parts with a shop cloth and keep them.
Replace a deformed or damaged clip.
If a part is specified as a non-reusable part, always replace it with new one.
Be sure to tighten bolts and nuts securely to the specified torque.
After re-installation is completed, be sure to check that each part works normally.
Follow the steps below to clean components.
–Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the
fouled area.
Then rub with a soft and dry cloth.
–Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub
with a soft and dry cloth.

Seat Status Output Signal
Depending on the seat status, the “passenger seat control unit” sends the seat status output signal to the
“soft top control unit”.
The “soft top control unit” controls the soft top open/close operation based on whether the seat status sig-
nal is ON or OFF. For details about soft top control, refer to RF-19, "
Operation Chart" .
*3: After that, seat condition signal stays ON if cancel switch turns to AUTO.
The seat status signal turns ON only when power window DOWN signal input is ON.
*4: If tilt forward/backward operation stops as a result of the conditions below, the tilt start position does not change.
The vehicle speed is approximately 7 km/h or more.
The seatback tilt switch is operated while the seatback is operating.
The ignition switch is turned to the START position. Stop conditions
A power seat switch (sliding or reclining) is operated.
Reclining motor lock is detected (return operation only).
The seatback tilt switch is operated while the seatback is operating.
The seatback tilt cancel switch is turned to CANCEL.
Pause condition
The ignition switch is turned to the START position.
