SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005396972
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:0000000005396973
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.

BRAKE PEDAL
1. Disconnect accelerator pedal position sensor harness connec-tor.
2. Remove stop lamp switch and ASCD cancel switch (if equipped) from brake pedal assembly.
3. Remove snap pin and clevis pin from clevis of brake booster.
4. Remove nuts from brake pedal bracket, and remove brake pedal assembly from vehicle.
5. Remove accelerator pedal from brake pedal assembly.
INSPECTION AFTER REMOVAL
• Check brake pedal upper rivet for deformation.
• Make sure that the lapping length of sub-bracket and slide plate is at least 6.9 mm (0.272 in).
• Check brake pedal for bend, damage, and cracks on the welded parts.
• Replace brake pedal assembly if any non-standard condition is
detected.
• Check clevis pin and plastic stopper for damage and deformation. Replace clevis pin as necessary.
INSTALLATION
1. Install the accelerator pedal on the brake pedal assembly. Refer to ACC-4, "Removal and Installation".
2. Install the brake pedal assembly on the lower dash panel and tighten the brake pedal assembly nuts in the order as shown to
specification.
3. Installation of the remaining components are in the reverse order of the removal. • After installing brake pedal assembly to vehicle, adjust brake pedal. Refer to BR-6, "
Inspection and
Adjustment".
• After installing accelerator pedal, check accelerator pedal. Refer to ACC-4, "
Removal and Installation".

CAUTION:
• Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
• While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
• It is not necessary to remove torque member mounting bolts and brake hose except for disassembly
or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake hose is
not under tension.
• Do not damage piston boot.
• If any shim is subject to serious corrosion, replace it with a new one.
• Keep rotor free from brake fluid.
• When replacing brake pad, replace shim with a new one.
