PRECAUTIONS

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

INFOID:0000000009886025

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 WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT 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 for Transfer Assembly and Transfer Control Unit Replacement

INFOID:0000000009886026

When replacing transfer assembly or transfer control unit, check the 4WD shift indicator pattern and adjust-

ment of the position between transfer assembly and transfer control unit if necessary.

CHECK 4WD SHIFT INDICATOR PATTERN

1. Set 4WD shift switch to 2WD, 4H, 4LO, 4H and 2WD in order. Stay at each switch position for at least 2

seconds.

2. Confirm 4WD shift indicator lamp and 4LO indicator lamp are changed properly as follows.

• If inspection results are normal, the position between transfer assembly and transfer control unit is cor-

rect.

• If inspection results are abnormal, the position is different between transfer assembly and transfer con-

trol unit.

Adjust the position between transfer assembly and transfer control unit. Refer to pattern table below.

Transfer position adjustment pattern

NOTE:
Method of adjustment can be chosen voluntarily, according to location of 4WD shift switch.

METHOD FOR ADJUSTMENT WITH 4WD SHIFT SWITCH AT 2WD

Select Adjustment Pattern

1. Start engine. Run engine for at least 10 seconds.
2. Check 4WD shift indicator lamp and 4LO indicator lamp.

To shift between 4H 

⇔ 4LO, stop vehicle and shift transmission 

shift selector to the "N" position with brake pedal depressed.

4LO

ON

The 4WD shift switch will not shift to the desired mode if the trans-
mission is not in "N" or the vehicle is moving.
You must wait for the 4LO indicator lamp to stop flashing and re-
main lit or turned off before shifting your transmission into gear or 
releasing the clutch pedal.
