PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005398096
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 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS 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 NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect 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 SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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:0000000005398097
NOTE:
• This Procedure is applied only to models with Intelligent 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.

WARNING:
Be sure to perform this step
when the engine is stopped.
NOTE:
On vehicles not equipped with A/C, there is an idler pulley in the position for the drive belt routing.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range.
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of t he possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000005398112
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000005398113
REMOVAL
1. Remove fender protector (RH). Refer to EI-24, "Removal and Installation".
2. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
WARNING:
Never place hand in a location where pinching may occur if
the holding tool acci dentally comes off.
CAUTION:
Do not loosen the auto-tensione r pulley bolt. (Do not turn it
counterclockwise.) If turned counterclockwise, the com-
plete auto-tensioner must be replaced as a unit, including
pulley.
3. Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of t he retaining boss to fix drive belt auto-tensioner.
• Leave tensioner pulley arm locked until belt is installed again.
4. Remove drive belt.
