PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AGS000GO
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 Necessary for Steering Wheel Rotation After Battery DisconnectAGS000L5
NOTE:
This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″ LOCK ″ position.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Steering SystemAGS000GP
Before disassembly, thoroughly clean the outside of the unit.
Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
For easier and proper assembly, place disassembled parts in order on a parts rack.

ANTI-PINCH FUNCTION
The CPU of sunroof motor 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
125 mm (4.92 in) or more in an open direction (when slide close operate).
close operation and tilt down when ignition switch is in the ON position.
close operation and tilt down during retained power operation.
MEMORY RESET PROCEDURE
1. Please observe the following instructions while 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.)
2. Initialization of system should be conducted after the following conditions.
When the battery is out or connector is disconnected while sunroof is operating or within 5 seconds
after sunroof stops.
When the sunroof motor is changed.
When an emergency handle is used.
When the sunroof does not operate normally. (Incomplete initialization conditions)
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1. Close the sunroof if it is not in the closed position. It may be necessary to repeatedly push the switch to close the sunroof.
2. Press and hold the TILT UP switch. Do not release the switch, keep pressure on it. After 10 seconds of depressing, the sunroof will tilt up, then tilt down. Release the button.
3. Press and hold the TILT UP switch again. Do not release the switch, keep pressure on it. While depress- ing the switch, the sunroof will “Slide open” “Slide close” “Tilt up” “Tilt down”. Release the button after the
sunroof “Tilts down” and stops.
4. Initializing procedure is complete. Confirm proper operation of the sunroof (slide open, slide close, tilt up, tilt down.)
