PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703094
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 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 har-
ness connectors.

Checking Fuel LineINFOID:0000000001703097
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001703098
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
• Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
• Use gasoline required by the regulations for octane number. Refer to GI-4, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
• Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines. Refer to EC-78, "
Fuel Pressure Check".
- 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.
• Perform work on level surface.
• Do not tighten hose clamps excessively to avoid damaging hoses.
• After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that 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 by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube 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.
• For servicing “Evaporative Emission System” parts, refer to EC-31
.
• For servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to EC-38
.

REMOVAL
WARNING:
Be sure to read “General Precautions” before working on the fuel system. Refer to FL-4, "
General Pre-
caution" .
1. Check fuel level with the vehicle on a level surface. If the fuel
gauge indicates more than the level as shown (7/8 full), drain
fuel from the fuel tank until the fuel gauge indicates level as
shown (7/8 full).
NOTE:
Fuel will be spilled when removing fuel pump assembly if fuel
level is above the fuel pump assembly installation surface.
• As a guide, fuel level is at the level as shown or below when
approximately 12 (3 1/8 US gal, 2 5/8 Imp gal) of fuel is
drained from a full fuel tank.
• In case fuel pump does not operate, perform the following pro-
cedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
drain fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-9
.
c. Insert fuel tubing into fuel tank through fuel filler hose to drain fuel from fuel tank.
2. Open fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
3. Release the fuel pressure from the fuel lines. Refer to EC-78, "
Fuel Pressure Check" .
4. Remove rear seat bottom. Refer to SE-14
.
5. Turn the four retainers 90° in a clockwise direction and remove the fuel pump inspection hole cover.
