Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006600488
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 “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
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 “SRS AIR BAG”.
• 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.
• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by
the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
vice.
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 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000006600489
NOTE:
• Before removing and installing any control units, first turn the ignition switch to the LOCK position, then dis-
connect both 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 diagnosis 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 battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

Service Notice or Precautions for Transfer
INFOID:0000000006359885
• 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.
• Never 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.

4WD SYSTEM : System Description
INFOID:0000000006359897
• 4WD mode is selectable among 2WD, 4WD-V, and 4WD by operating the 4WD mode switch.
• When judging driving conditions and road surface conditions based on signals transmitted from each sensor
and switch, the 4WD system automatically controls torque distribution of front and rear wheels and both rear
wheels, depending on the situation.
• In accordance with fail-safe function, when system is malfunctioning, 4WD control stops, and the system
becomes rear wheel drive. Refer to
DLN-19, "4WD SYSTEM : Fail-safe"
• When a high load status continues for electric controlled coupling, 4WD control temporarily becomes rear
wheel drive, according to protection function. Refer to
DLN-21, "4WD SYSTEM : Protection Function"
.
4WD SYSTEM : Torque Split Control
INFOID:0000000006543008
2WD mode
• Vehicle is in front-wheel drive.
4WD-V mode
Normal Control
• 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 (Front wheel drive) and 50 : 50 (4WD) to
have an optimized torque distribution adapted to road condition change.
• When spin occurs on front wheel, distribute optimum torque to rear wheel and keep stable driving.
• 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.
Cornering Control
• Torque between both rear wheels is automatically changed between 100 : 0 and 0 : 100 for distributing opti-
mum torque that depends on the driving conditions and road surface conditions.
• Producing a difference between both rear wheels enables sporty and smooth handling.
Combination meter
Mainly transmits the following signals via CAN communication line to 4WD control
module.
• Parking brake switch signal
