PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612922
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.

Precaution for ICC System ServiceINFOID:0000000001328803
 Never look straight into the laser beam discharger when adjusting laser beam aiming.
 Turn the MAIN switch OFF in conditions similar to dr iving, such as free rollers or a chassis dynamometer.
 Do not use the ICC sensor removing from v ehicle, disassemble, or remodel the sensor.
 Erase DTC when replacing parts of ICC system, then c heck the operation of ICC system after adjusting laser
beam aiming if necessary.

LASER BEAM AIMING ADJUSTMENT
5. Pivot the edge of the target board 20
° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift rates the 20 ° movement.
6. Do not place anything in the space shown in the figure (view from top). NOTE:
In case the space shown in the figure is not availabl e, make space by covering the side of the target board
with a 400 mm (15.75 in)-size frosted black board or black cloth.
Aiming AdjustmentINFOID:0000000001328816
CAUTION:
Never view ICC sensor integrated unit body windo w directly during laser beam aiming adjustment.
NOTE:
Complete all necessary work for laser beam adjustment until the adjustment completes as shown in the proce-
dure. If the procedure does not complete, the ICC system is inoperable.
1. Connect CONSULT-III and select “Work Support” of “ICC”.
2. Select “LASER BEAM ADJUST”.
3. Touch “START”.
NOTE:
If the adjustment screen does not appear on the CO NSULT-III screen in 10 seconds. After touching
“LASER BEAM ADJUST” screen, the following causes may be considered:
 Target is not set accurately.
 There is not enough space beside the target.
 Deformation of vehicle or the surrounding equipm ent unit, bracket, or the surrounding equipment is
causing inappropriate installation of sensor and aiming may be set out of the adjustable range.
 The area is not suitable for the adjustment work.
 ICC sensor is not clean.
 The ICC system warning lamp illuminates.
4. After the CONSULT-III displays “ADJUST THE VER TICAL OF LASER BEAM AIMING” turn the up-down
direction adjusting screw until “U/D CO RRECT” value is set in the range of ±4.
