Precaution for Supplemental Restraint S
ystem (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005877756
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 electri c 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 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005877757
NOTE:
This Procedure is applied only to models with Intelli gent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.

6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Servicing Rear Final DriveINFOID:0000000004193549
Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
Check for the correct installation status prior to removal or disassembly. When matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
Overhaul should be done in a clean work area, a dust proof area is recommended.
Before disassembly, completely remove sand and mud fr om the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
Always use shop paper for cleaning the inside of components.
Avoid using cotton gloves or a shop cloth to prevent the entering of lint.
Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace them with new ones if necessary.
Gaskets, seals and O-rings should be replaced any time the unit is disassembled.
Clean and flush the parts sufficiently and blow them dry.
Be careful not to damage sliding surfaces and mating surfaces.
When applying sealant, remove the old sealant from t he mating surface; then remove any moisture, oil, and
foreign materials from the application and mating surfaces.
In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a tightening sequence is specified, observe it.
During assembly, observe the specified tightening torque.
Add new differential gear oil, petroleum jell y, or multi-purpose grease, as specified.

FRONT OIL SEAL
1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly until it becomes flush
with the gear carrier using Tool.
CAUTION:
Do not reuse front oil seal.
Do not incline the new fron t oil seal when installing.
Apply multi-purpose grease to the lips of the new front oil
seal.
2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using suitable tool (A),
and check the total preload torque using Tool (B).
The total preload torque should be within the total preloadtorque specification. When not replacing the collapsible
spacer, it should also be equal to the measurement taken dur-
ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).
If the total preload torque is low, tighten the drive pinion lock nut in 6.8 N·m (0.69 Kg-m, 5ft-lb) increments until the total pre-
load torque is met.
CAUTION:
Do not reuse drive pinion lock nut.
Apply anti-corrosive oil to th e threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to DLN-253, "Disassembly and
Assembly".
Do not loosen drive pinion lock nu t to adjust the total preload torque. If the total preload torque
exceeds the specifications, replace the collapsible sp acer and tighten it again to adjust. Refer to
DLN-253, "Disassembly and Assembly"
.
After adjustment, rotate drive pinion back and fo rth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
4. Installation of the remaining components is in the reverse order of removal. CAUTION:
Check the differential gear oil level after installation. Refer to DLN-244, "Checking Differential Gear
