PRECAUTIONS

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

INFOID:0000000009760248

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. Information necessary to service the system safely is included in the SR and SB section of

this Service Manual.

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

Service Manual. 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.

Precaution for Battery Service

INFOID:0000000009177701

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.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009177702

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc. to prevent damage to

windshield.

Service Notice or Precautions for Transfer

INFOID:0000000009177703

• After overhaul refill the transfer with new transfer oil.

• Check the oil level or replace the oil only with the vehicle parked on level surface.

• During removal or installation, keep inside of transfer clear of dust or dirt.

• Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern. Fit-

ting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause lon-

gitudinal vibration.

• Disassembly should be done in a clean work area.
