Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010590148
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 SR 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 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 Battery Service
INFOID:0000000010590149
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000010590150
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc. to prevent damage to
windshield.
Service Notice or Precautions for Transfer
INFOID:0000000010590151
• After overhaul refill the transfer with new transfer oil.
• Check the oil level or replace the oil only with the vehicle parked on level surface.
• During removal or installation, keep inside of transfer clear of dust or dirt.
• Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern. Fit-
ting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause lon-
gitudinal vibration.
• 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 matching marks are required, be
certain 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 one if necessary.
• Gaskets, seals, O-rings and lock nuts should be replaced any time when 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.

STRUCTURE AND OPERATION
ELECTRIC CONTROLLED COUPLING
1.
The 4WD control unit supplies command current to electric con-
trolled coupling (4WD solenoid).
2.
The control clutch is engaged by electromagnet and torque is
detected in control clutch.
3.
The cam operates in response to control clutch torque and
applies pressure to main clutch.
4.
The main clutch transmits torque to front wheels according to
pressing power.
• Transmission torque to the rear wheels is determined accord-
ing to command current.

4WD SYSTEM : System Description
INFOID:0000000010755231
• Pressing force of multiple disc clutch is controlled by electric control. Driving torque distribution of front and
rear wheels changes automatically between approximately 100 : 0 (2WD) and 50 : 50 (4WD) to have an opti-
mized torque distribution adapted to road condition change.
• Driving mode is selectable among 2WD mode, AUTO mode, and LOCK mode by operating the 4WD mode
switch.
• In accordance with fail-safe function, when system is malfunctioning, 4WD control stops, and the system
becomes 2WD or slight 4WD (rear-wheels still have some driving torque). Refer to
.
• When a high load status continues for electric controlled coupling, 4WD control temporarily becomes front
wheel drive, according to protection function. Refer to
DLN-18, "4WD SYSTEM : Protection Function"
.

4WD SYSTEM : Control in Each Mode
INFOID:0000000010755232
2WD MODE
• Vehicle is in front-wheel drive.
CAUTION:
If front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties
for the system.
NOTE:
The 4WD control unit may distribute the minimum necessary driving torque to rear wheels even when the
2WD mode is selected, depending on the driving condition. (However AUTO or LOCK indicator lamp does not
illuminate.)
AUTO MODE
• Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
• Pressing force of multiple disc clutch is controlled by electric control. Driving torque distribution of front and
rear wheels changes automatically between approximately 100 : 0 (2WD) and 50 : 50 (4WD) to have an opti-
mized torque distribution adapted to road condition change.
• Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by distrib-
uting optimum torque to rear wheels.
Vehicle Starts Control
• At the start, torque distribution for front and rear wheels is fixed by electric control and stable start is
achieved.
• Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
Normal Control
• On roads which do not require 4WD, it contributes to improved fuel economy by driving in conditions close to
front-wheel drive and it results in better fuel efficiency.
• When spin occurs on front wheel, distribute optimum torque to rear wheel and keep stable driving.
• The vehicle cornering status is judged according to information from each sensor, and the optimum torque is
distributed to rear wheels for preventing tight cornering/braking symptom.
LOCK MODE
• Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
• In LOCK mode, the pressing force to the multiple disc clutches is maximized by the electronic control and
the driving torque distribution of front and rear wheels is fixed to obtain the 4WD status of approximately 50 :
50.
NOTE:
Only torque distribution may be switched to the control same as the one in AUTO mode, depending on the
driving condition.
• LOCK mode will change to AUTO mode automatically, when the vehicle has been driven at a high speed.
Then LOCK mode control is canceled and the LOCK indicator lamp turns off.
• When vehicle speed exceeds the specified speed, the mode cannot be switched from AUTO mode to LOCK
mode.
• LOCK mode will change to AUTO mode automatically, when the ignition switch is turned OFF in LOCK
mode.
NOTE:
