PRECAUTION

PRECAUTIONS

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

INFOID:0000000004212376

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:0000000004212377

Refer to 

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

.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004212378

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI

VEHICLE IMMOBILIZER SYSTEM - NATS).

• Remove and install all control units after disconnecting both 12-volt battery terminals 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 NVIS/IVIS, an electrically controlled steering lock

mechanism is adopted on the key cylinder.

For this reason, if the 12-volt battery is disconnected or if the 12-volt battery is discharged, the steering wheel

will lock and steering wheel rotation will become impossible.

If steering wheel rotation is required when 12-volt battery power is interrupted, follow the procedure below

before starting the repair operation.

OPERATION PROCEDURE

1. Connect both 12-volt battery terminals.

NOTE:

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

2. 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.

3. Disconnect both 12-volt battery terminals. The steering lock will remain released and the steering wheel

can be rotated.

4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the 

″LOCK″ position before connecting

the 12-volt battery terminals. (At this time, the steering lock mechanism will engage.)

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