PRECAUTIONS

PRECAUTION

PRECAUTIONS

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

INFOID:0000000003935605

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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004448898

NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables 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 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-III.

Precaution for Work

INFOID:0000000003935606

• When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, be sure to protect it with a shop cloth.

2009 Pathfinder

ADP-154

< PRECAUTION >

PRECAUTIONS

• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and keep them.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After re-installation is completed, be sure to check that each part works normally.
• Follow the steps below to clean components.
- Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the

fouled area.
Then rub with a soft and dry cloth.

- Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe

the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub with
a soft and dry cloth.

• Do not use organic solvent such as thinner, benzene, alcohol, or gasoline.
• For genuine leather seats, use a genuine leather seat cleaner.
