PRECAUTIONS

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

INFOID:0000000009757014

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 Procedure without Cowl Top Cover

INFOID:0000000009757015

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 Clutch

INFOID:0000000009757016

WARNING:

After cleaning clutch disc, wipe it with a dust collector. Do not use compressed air.

CAUTION:

• Clutch fluid use refer to 

MA-11, "Fluids and Lubricants"

.

• Do not reuse drained clutch fluid.

• Keep painted surface on the body or other parts free of clutch fluid. If it spills, wipe up immediately

and wash the affected area with water.

• Do not use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic

system.

• Do not reuse CSC (Concentric Slave Cylinder). Because CSC slides back to the original position

every time when removing transaxle assembly. At this timing, dust on the sliding parts may damage

a seal of CSC and may cause clutch fluid leakage. Refer to 

CL-16, "Removal and Installation"

.

• Do not disassemble clutch master cylinder and CSC.
