PRECAUTIONS

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

INFOID:0000000012198139

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, it is recommended that all maintenance

and repair be performed by an authorized NISSAN/INFINITI dealer.

• Improper repair, 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 or batteries, and wait at least 3 minutes before performing any service.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000012198140

When performing the procedure after removing cowl top cover, cover

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

windshield.

Precautions For Xenon Headlamp Service

INFOID:0000000012198141

WARNING:

Comply with the following warnings to prevent any serious accident.

• Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-

ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage

generated parts.

• Never work with wet hands.

• Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon

headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
