PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010138152
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
Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT 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 three minutes before performing any service.

3. Remove front RH and LH blade assembly from the front RH and LH arm.
Installation
1. Operate wiper motor one full cycle, then turn "OFF" (Auto Stop).
2. Clean up the pivot area as shown. This will reduce possibility of
wiper arm looseness.
3. Install front RH and LH blade assembly on the front RH and LH arm.
4. Install front RH wiper arm and front LH wiper arm.
5. Ensure that wiper blades stop within proper clearance. Perform "FRONT WIPER ARM ADJUSTMENT".
6. Tighten wiper arm nuts to specified torque, and install wiper arm covers. Refer to
.
FRONT WIPER ARM ADJUSTMENT
1. Operate wiper motor one full cycle, then turn “OFF” (Auto Stop).
2. Lift the wiper blade up and then rest it onto glass surface, check
the blade clearance (A) and (B).
3. Operate the wiper motor one half cycle so that the wiper arms
are in the upright position and stop arms there, then check the
blade clearances at (C) and (D).
4. Remove wiper arm covers and wiper arm nuts.
5. Adjust front wiper arms on wiper motor pivot shafts to obtain above specified blade clearances.
6. Tighten wiper arm nuts to specified torque, and install wiper arm covers. Refer to
.
