PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000007578026

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

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
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”.

• 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• 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
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.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000007578027

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

SYSTEM

AUTO OPERATION

Sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof with-
out holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.

RETAINED POWER OPERATION

Retained power operation is an additional power supply function that enables sunroof system to operate dur-
ing 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 again.
• When timer time passes. (45 seconds)

ANTI-PINCH FUNCTION

The CPU of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-
closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until full up position (when tilt down operate) or
150 mm (5.91 in) or more in an open direction (when slide close operate).

INFOID:0000000007578038

MEMORY RESET PROCEDURE

Please observe the following instructions at confirming the sunroof operation.
NOTE:
Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof
stops (to wipe-out the memory of lid position and operating friction).

Initialization of system should be conducted after the following conditions.
• When the sunroof motor is changed.
• When the sunroof does not operate normally. (Incomplete initialization conditions)

ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Re-
quirement

INFOID:0000000007578039

INITIALIZATION PROCEDURE

If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1.

Press tilt up switch several times and set glass lid to the tilt up position.

Release the tilt up switch once, press the tilt up switch again, press and hold the switch until lid pops up.

The glass lid moves slight toward tilt up direction then stop. (Press and hold the switch during this opera-
tion)

Release the switch again, and press the tilt up switch within the first 4 seconds. (Press and hold the
switch)

After 4 seconds, the glass lid will be automatically operated in sequence of tilt down, slide open and slide
close.

After the glass lid stops, release the switch 0.5 second later. (Press and hold the switch during this opera-
tion)

If slide switch operates normally, this initialization is done.

ANTI-PINCH FUNCTION

Full open the sunroof.

Place a wooden piece (wooden hammer handle, etc.) at near fully closed position.

Close the sunroof completely with auto-slide close.

Check that sunroof lowers for approximately 150 mm (5.91in) or 2 seconds with out pinching a wooden piece
and stops.

CAUTION:

• Never check with hands and other part of body because they may be pinched. Never get pinched.
• Depending on environment and driving conditions, if a similar impact or lord is applied to the sun-

roof it may lower.

• Check that auto-slide operates before inspection when system initialization is performed.
• Perform initial setting when auto-slide operation or anti-pinch function does not operate normally.
