AWD WARNING LAMP BLINKS QUICKLY
AWD WARNING LAMP BLINKS QUICKLY
Description
INFOID:0000000003302091
While driving, AWD 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:0000000003743925
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 “SRS AIRBAG” and “SEAT BELT” 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 “SRS AIRBAG”.
• 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
When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003743926
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Service Notice or Precautions for Transfer
INFOID:0000000003450868
• 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.

Revision: 2008 October

DLN-42
< PRECAUTION >
[TRANSFER: TY20A]
PRECAUTIONS
• 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.
