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

INFOID:0000000010297290

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. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

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

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000010297291

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-

THEFT SYSTEM).

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

in the LOCK position.

• Always use CONSULT 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.

Precautions for Drive Shaft

INFOID:0000000010297292

CAUTION:

Note the following precautions when disassembling and assembling drive shaft.
• Joint sub-assembly does not disassemble because it is non-overhaul parts.
• Perform work in a dust-free location.
• Before disassembling and assembling, clean the parts.
• Prevent the entry of foreign objects during disassembly of the service location.
• Parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover must

be placed over parts.

• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint

adhering to parts.

• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be

removed by blowing with air or wiping with paper shop cloths.

• When disassembling a joint or disassembling the drive shaft from the transaxle, when exists,

replace the circlip.
