NORMAL OPERATING CONDITION

Description

INFOID:0000000001088451

While driving, 4WD warning lamp blinks 2 times in 1 second and it turns OFF after 1 minute.
• This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and

multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before lamp blinks quickly. Both cases are not malfunction.

• When this symptom occurs, stop vehicle and allow it to idle for some times. Blinking will stop and system will

be restored.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000001070056

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 SRC 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 SRC 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.

Service Notice or Precautions for Transfer

INFOID:0000000000972123

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.
• 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.
