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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.

Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM -
NATS) (If Equipped)

NAS0001A

NVIS/IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS/IVIS
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

●

When NVIS/IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in
"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

●

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVIS/IVIS (NATS) initialization and NVIS/IVIS (NATS) ignition key ID regis-
tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).

Therefore, CONSULT-II NVIS/IVIS (NATS) software (program card and operation manual) must be kept
strictly confidential to maintain the integrity of the anti-theft function.

●

When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis-
tered into NVIS/IVIS (NATS).

●

When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.

Leave the ignition key in "ON" position for approximately 5 seconds.

Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.

Repeat step 1 and 2 again.

Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS

Precautions Necessary for Steering Wheel Rotation After Battery Disconnect

NAS0009O

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 battery cables with the ignition knob in the

″

LOCK

″

position.

●

Always use CONSULT-II 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 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-II.
