SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000001720987
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 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 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.

Checking Fuel Line INFOID:0000000001720990
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace faulty parts as necessary.

General Precaution INFOID:0000000001720991
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: INFLAMMABLE” sign in the work area.

• Be sure to work in a well ventilated area and have a CO
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
CAUTION:
• 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-77, "
- Disconnect the battery ground cable.
• 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.
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

• 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.
- a) Apply fuel pressure to the fuel lines by turning the ignition
switch to ON (without starting the engine). Then check for fuel
leaks at the fuel tube connections.
- b) Start the engine and rev the engine, then check for fuel
leaks at the fuel tube connections.
• After installing tubes, run engine 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-30
.
• For servicing “On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-36

assembly electrical connector; EVAP hose; and fuel feed hose
from the fuel level sensor unit, fuel filter, and fuel pump assembly.
a. Disconnect the quick connectors as follows:
• Hold the sides of the connector, push in tubs and pull out the
tube.
• If the connector and the tube are stuck together, push and pull
several times until they start to move. Then disconnect them
by pulling.
CAUTION:
• The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid liquid such as battery electrolyte, from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor,
fuel filter, and fuel pump assembly.
• When the tube or fuel level sensor, fuel filter, and fuel pump assembly is replaced, also replace
the retainer with a new one (green colored retainer).
• To keep the connecting portion clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
