Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006228171
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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision that would result in air ba g inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
 Do not use electrical test equipm ent 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 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 Wh eel Rotation after Battery Disconnect
INFOID:0000000006228172
NOTE:
 Before removing and installing any control units, first tu rn the push-button ignition switch to the LOCK posi-
tion, then disconnect 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 diagnos is 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 batte ry disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock wil l remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

Precaution for Servicing Front Final DriveINFOID:0000000006222373
 Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
 Check for the correct installation status prior to re moval or disassembly. When matching marks are required,
be certain they do not interfere with the f unction 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 from 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 dam age, 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 the mating surface; then remove any moisture, oil, and
foreign materials from the application and mating surfaces.
 In principle, tighten nuts or bolts gradually in severa l 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 jelly, or multi-purpose grease, as specified.
