PRECAUTIONSPFP:00001
DescriptionBAS0006Z
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BAS00070
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 and SB section of
this Service Manual.
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 NATS (NISSAN ANTI-THEFT SYSTEM)BAS00071
NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.

When 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 NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly con-
fidential to maintain the integrity of the anti-theft function.

When servicing NATS (trouble diagnoses, system initialization and additional registration of other 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 registered into NATS.

When failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectBAS00072
NOTE:

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 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 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
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if 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 battery cables. 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 battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
General PrecautionsBAS00073

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
