PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005550691
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 Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000005550692
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
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.

Precaution for Transfer Assembly and Transfer Control Unit Replacement
INFOID:0000000005258429
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 OK, the position between transfer assembly and transfer control unit is correct.
• If NG, the position is different between transfer assembly and transfer control 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.

Precaution
INFOID:0000000005258431
•
Before connecting or disconnecting the transfer control unit
harness connector, turn ignition switch “OFF” and disconnect
the battery cables. Battery voltage is applied to transfer con-
trol unit even if ignition switch is turned “OFF”.
•
When connecting or disconnecting pin connectors into or
from transfer control unit, take care not to damage pin termi-
nals (bend or break).
When connecting pin connectors make sure that there are not

Service Notice
INFOID:0000000005258432
• After overhaul refill the transfer with new transfer fluid.
• Check the fluid level or replace the fluid only with the vehicle parked on level ground.
• During removal or installation, keep inside of transfer clear of dust or dirt.
• Disassembly should be done in a clean work area.
• Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
• Check for the correct installation status prior to removal or disassembly. If matchmarks are required, be cer-
tain they do not interfere with the function of the parts when applied.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
• Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.
• Gaskets, seals and O-rings should replaced any time the transfer is disassembled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, use it.
• Observe the specified torque when assembling.
• Clean and flush the parts sufficiently and blow-dry them.
• Be careful not to damage sliding surfaces and mating surfaces.
• Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.
