PRECAUTIONS

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

INFOID:0000000004211683

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 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 SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

Precautions For High-Voltage System

INFOID:0000000004211684

Refer to 

GI-24, "Precautions For High-Voltage System"

.

Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004501285

NOTE:

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both 12-volt battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both 12-

volt battery cables.

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

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

This vehicle is equipped with a push-button ignition switch and a steering lock unit.

If the 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

If turning the steering wheel is required with the 12-volt battery disconnected or discharged, follow the proce-

dure below before starting the repair operation.

OPERATION PROCEDURE

1. Connect both 12-volt battery cables.

NOTE:

Supply power using jumper cables if 12-volt battery is discharged.

2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

3. Disconnect both 12-volt battery cables. The steering lock will remain released with both 12-volt battery

cables disconnected and the steering wheel can be turned.

4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both 12-volt battery cables. With the brake pedal released,

turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steer-

ing wheel will lock when the push-button ignition switch is turned to LOCK position.)

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

• 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

• 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.
