PRECAUTIONS

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

EBS00T2G

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 and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.

General Precautions

EBS00QUD

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 the workshop with a CO

fire extinguisher.

●

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

CAUTION:

●

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

GI-5, "Precautions

for Fuel (Unleaded Premium Gasoline Recommended)"

●

Before removing fuel line parts, carry out 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

EC-79, "FUEL PRESSURE RELEASE"

–

Disconnect the battery negative terminal.

●

Always replace O-rings and clamps with new ones.

●

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

●

Do not tighten hose clamps excessively to avoid damaging hoses.

●

Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end.

●

Ensure that clamp screw does not contact adjacent parts.

PRECAUTIONS

FL-3

2007 Pathfinder

●

After connecting the fuel tube quick connectors, make sure
the quick connectors are secure.
Ensure that the connector and resin tube do not contact
any adjacent parts.

●

After installing tubes, make sure there is no fuel leakage at
connections in the following steps.

–

Apply fuel pressure to fuel lines with turning ignition switch
ON (with engine stopped). Then check for fuel leaks at con-
nections.

–

Start the 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.

●

For servicing “Evaporative Emission System” parts, refer to

EC-32, "EVAPORATIVE EMISSION SYSTEM"

●

For servicing “On Board Refueling Vapor Recovery
(ORVR)” parts, refer to

EC-39, "ON BOARD REFUELING

VAPOR RECOVERY (ORVR)"
