Precautions for Removing Battery Terminal
INFOID:0000000010508557
• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key
or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
• When disconnecting the 12V battery terminal, turn off the ACC
power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
HOW TO DISCONNECT 12V BATTERY TERMINAL
Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.
INSTRUCTION 1
1.
Open the hood.
2.
Turn key switch to the OFF position with the driver side door opened.
3.
Get out of the vehicle and close the driver side door.
4.
Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.
CAUTION:
While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.
5.
Remove 12V battery terminal.
CAUTION:
After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.
INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)
1.
Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.
2.
Open the driver side door.
3.
Open the hood.
4.
Close the driver side door.
5.
Wait at least 3 minutes.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010505230
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.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, 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 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 “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never 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 Procedure without Cowl Top Cover
INFOID:0000000010505229
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:0000000010288327
CAUTION:
• 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 pat-
tern. Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and
can cause longitudinal vibration.
• Disassembly should be done in a clean work area.
PIIB3706J
DLN-100
< PRECAUTION >
[TRANSFER: TY30A]
PRECAUTIONS
• 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 inspec-
tion 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 disassem-
bled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-
side. If tightening 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.

System Description

DESCRIPTION
• AWD controls distribution of drive power between front-wheel drive (100:0) and AWD (50:50) conditions
according to signals from sensors.
• It transmits/receives each signal from the following control unit via CAN communication line.
*: With ESP
AUTO Mode
• Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
• AWD mode makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
• On roads which do not require AWD, AUTO mode contributes to improved fuel economy by driving in condi-
tions close to front-wheel drive.
• Sensor inputs determine the vehicle's turning condition, and tight cornering/braking are controlled by distrib-
uting optimum torque to rear wheels.

• Front/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
• Vehicle will switch automatically to AUTO mode if vehicle speed increases. If vehicle speed then decreases,
the vehicle automatically returns to direct 4-wheel driving conditions.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
LOCK mode may be prohibited, or speeds at which LOCK mode is enabled may be restricted detecting tire
conditions.
2WD Mode
Vehicle is in front-wheel drive.
NOTE:
• If front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for the
system.
• Even if the AWD mode switch is in 2WD mode, the AWD control unit occasionally automatically change to
AUTO mode depending on the driving condition (For example; Depressing the acceleration firmly). This is
not malfunction. However, AWD indicator lamp dose not illuminate.

OPERATION PRINCIPLE
Electric Controlled Coupling
1.
The AWD control unit supplies command current to electric con-
trolled coupling (AWD 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.
