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

INFOID:0000000003938884

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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004448850

NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

Use the Intelligent Key or mechanical key to turn the ignition switch to the

″

ACC

″

position. At this time, the

steering lock will be released.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

Perform the necessary repair operation.

When the repair work is completed, return the ignition switch to the

″

LOCK

″

position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

Perform a self-diagnosis check of all control units using CONSULT-III.

General Precaution

INFOID:0000000003938885

WARNING:

When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the workshop.

PRECAUTIONS

FL-3

< PRECAUTION >

• 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-38, "Precaution

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-484, "Fuel Pressure Check"

(VQ40DE),

EC-951,

"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-487, "Removal and Installation"

(VQ40DE),
