Precautions

Precaution for Supplemental Restraint System (srs) "air Bag" and "seat Belt Pre-Tensioner"

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

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 collisions.

Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” sections 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 Service 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/power switch 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/power switch OFF, disconnect the 12V battery or batteries, and wait at least 3 minutes before performing any service.

Precautions for Drive Shaft

Precautions for Drive Shaft

Observe the following precautions when disassembling and assembling drive shaft.

  • Do not disassemble joint sub-assembly because it is non-overhaul parts.

  • Perform work in a location which is as dust-free as possible.

  • Clean the parts before disassembling and assembling.

  • Prevent the entry of foreign objects during disassembly of the service location.

  • Reassemble disassembled parts carefully in the correct order. If work is interrupted, a clean cover must be placed over parts.

  • Use paper shop cloths. Fabric shop cloths must not be used because of the danger of lint adhering to parts.

  • Clean disassembled parts (except for rubber parts) with kerosene which shall be removed by blowing with air or wiping with paper shop cloths.
