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

INFOID:0000000001282161

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 SR
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 SR 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 SR section.

• Do not use electrical test equipment on any circuit related to the SR unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

General Precaution

INFOID:0000000001282162

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

2

 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-40, "Precaution

for Fuel"

.

• 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-481, "Fuel Pressure Check"

 (VQ40DE), 

EC-948,

"Fuel Pressure Check"

 (VK56DE).

- 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.

• 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 con-

nections.

• 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-484, "Removal and Installation"

. 

• For servicing “On Board Refueling Vapor Recovery (ORVR)”

parts, refer to 

EC-483, "How to Detect Fuel Vapor Leakage"

.

REMOVAL

WARNING:

Follow the “General Precautions” before working on the fuel system. Refer to 

FL-2, "General Precau-

tion"

.

1.

Remove the fuel filler cap to release the pressure from inside the fuel tank.

2.

Remove the LH rear wheel and tire. Refer to 

WT-36, "Rotation"

.

3.

Check the fuel level on level gauge. If the fuel gauge indicates
more than the level as shown (half "1/2"), drain the fuel from the
fuel tank until the fuel gauge indicates the level as shown, or
less.
NOTE:
Fuel will be spilled when removing the lower fuel filler hose if the
level is above "1/2".
• As a guide, the fuel level reaches the fuel gauge position as

shown, or less, when approximately 43   (11 3/8 US gal, 9 1/2
Imp gal) of fuel are drained from the full fuel tank. 

• If the fuel pump does not operate, use the following procedure

to drain the fuel to the specified level.

a.

Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel filler pipe through the fuel filler
opening to drain the fuel from fuel filler pipe.

b.

Disconnect the fuel filler hose from the fuel filler pipe.

c.

Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.

4.

Release the fuel pressure from the fuel lines. Refer to 

EC-481, "Fuel Pressure Check"

 (VQ40DE), 

EC-

948, "Fuel Pressure Check"

 (VK56DE).

5.

Disconnect the battery negative terminal.

6.

Disconnect the lower fuel filler hose from the fuel tank, the EVAP hose, and the vent pipe quick connector.
• Disconnect the fuel feed hose from the molded clip in the side of the fuel tank.
Disconnect the quick connector as follows:
• Hold the sides of the connector, push in the tabs 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.

• The quick connector can be disconnected when the tabs

are completely depressed. Do not twist the quick connec-
tor more than necessary.

• Do not use any tools to disconnect the quick connector.
• Keep the resin tube away from heat. Be especially careful

when welding near the tube.

• Prevent any acid liquids such as battery electrolyte, from

getting on the resin tube.

• Do not bend or twist the resin tube during connection. 
• Do not remove the remaining retainer on the hard tube (or

the equivalent) except when the resin tube or the retainer
is replaced.

• When the resin tube or hard tube, or the equivalent, is 

replaced, also replace the retainer with a new one (semi-
transparent colored retainer).

• To keep the quick connector clean and to avoid damage

and contamination from foreign materials, cover the quick
connector with plastic bags or suitable material as shown.      

7.

On models equipped with fuel tank shield, remove the four bolts and remove the fuel tank shield.

8.

Remove the propeller shaft. Refer to 

DLN-308, "Removal and Installation"

 (2F1310), 

DLN-316, "Removal

and Installation"

 (2S1330), 

DLN-325, "Removal and Installation"

 (2S1350).

9.

Support the fuel tank using a suitable lift jack.

10. Remove the three fuel tank strap bolts while supporting the fuel

tank with a suitable lift jack.

11. Remove the fuel tank straps and slowly lower the fuel tank to access the top of the fuel level sensor, fuel

filter and fuel pump assembly.

CAUTION:

Do not lower the fuel tank too far to prevent damage to the fuel feed hose and the fuel level sensor,
fuel filter and fuel pump assembly connector.
