The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition 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 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation after Battery Disconnect
INFOID:0000000006222210
NOTE:
Before removing and installing any control units, first tu rn the push-button ignition switch to the LOCK posi-
tion, then disconnect bot h battery cables.
After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnos is according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the bat tery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock wi ll remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

Service Notice or Precautions for TransferINFOID:0000000006222211
CAUTION:
Use Genuine NISSAN Transfer Fluid. Refer to MA-10, "
Fluids and Lubricants".
Never reuse transfer fluid, once it has been drained.
Check the fluid level or repl ace the fluid only with the vehicle parked on level ground.
During removal or installati on, keep inside of transfer clear of dust or dirt.
Replace all tires at the same time. Always use tir es of the proper size and the same brand and pat-
tern. Fitting improper size and unusually worn tires applies excessive force to vehicle mechanism
and can cause longitudinal vibration.
Disassembly should be done in a clean work area, it is preferable to work in dustproof area.
Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the
internal parts from becoming contamin ated by dirt or other foreign matter.
All parts should be carefully cl eaned with a general purpose, non-flammable solvent before inspec-
tion or reassembly.
Check for the correct installation status prior to removal or disassembly. If matching marks are
required, be certain they do not interfere wit h the function of the parts when applied.
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 be replaced any time the transfer is disassembled.
In principle, tighten bolts or nu ts gradually in several steps workin g diagonally from inside to out-
side. If tightening sequence is specified, use it.
Observe the specified torque when assembling.
Clean and flush the parts su fficiently and blow-dry them.
Be careful not to damage sliding surfaces and mating surfaces.
Clean inner parts with lint-free cloth or towels . Do not use cotton work gloves and rags to prevent
adhering fibers.

DLN-14
< SYSTEM DESCRIPTION >[TRANSFER: ATX90A]
STRUCTURE AND OPERATION
DESCRIPTION
Ball ramp lever operates in the direction of main shaft axis according to rotation of actuator shaft and
presses piston. Pressure is applied to each clutch and torque is transmitted.
Shift fork operates in the direction of main shaft axis according to rotation of actuator shaft and performs
engagement and disengagement to Hi-Lo sleeve and lock sleev e of main shaft. Mode is switched between
4H ⇔4L.
AUTO MODE
The optimum torque distribution is electronically performed for front and rear wheels according to road con-
ditions.
Stable start without wheel spin is possible on slippery road conditions, such as on a snowy road.
When road condition does not require 4WD driving, the st atus becomes close to rear wheel drive, which
results in better fuel efficiency and prov ides FR-like steering characteristics.
The vehicle cornering status is judged according to information from each sensor, and the optimum torque is
distributed to front wheels for prev enting tight-corner braking symptom.
NOTE:
When there is a difference of revolution speed between the front and rear wheel the shift occasionally changes
to direct 4-wheel driving conditions aut omatically. This is not a malfunction.
4H MODE
Torque distribution for front and rear wheels is fixed and stable start is achieved while driving on an rough,
sandy or snowy road.
4L MODE
Large traction force is obtained due to low gear. High running ability and escaping ability are achieved.
Switching from 4H mode to 4L mode is not possible w hen the vehicle is not stopped and A/T shift selector is
not in the neutral position.
