Precautions Nissan Pathfinder

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.

General Precautions

WARNING:

When replacing fuel line parts, be sure to observe the following:

Put a “CAUTION: FLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO₂ fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.

CAUTION:

Use gasoline required by the regulations for octane number. Refer to Fuel.

Before removing fuel line parts, perform the following procedures:

Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in safe area.

Release fuel pressure from the fuel lines. Refer to Work Procedure.

Disconnect the battery cable from the negative terminal. Refer to Battery disconnect.

Always replace O-rings and clamps with new ones.

Do not kink or twist tubes when they are being installed.

Do not tighten hose clamps excessively to avoid damaging hoses.

After installing tubes, check that there are no fuel leaks at connections in the following steps.

Apply fuel pressure to fuel lines by placing ignition switch in the “ON” position (with engine stopped). Then check for fuel leaks at connections.

Start engine and rev it up and check for fuel leaks at connections.

Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the “MIL” may come on.
