REMOVAL
CAUTION:
• Before servicing, turn the ignition switch OFF, disconnect both battery terminals and wait at least
three minutes.
• Do not use air tools or electric tools for servicing.
1. Disconnect both the negative and positive battery terminal s, then wait at least three minutes. Refer to PG-
73, "Removal and Installation (Battery)".
2. Remove the steering column covers. Refer to IP-17, "Removal and Installation"
.
3. Rotate steering wheel clockwise to access first combination switch bolt and remove.
4. Rotate steering wheel counter-clockwise to access second combination switch bolt and remove.
5. Disconnect the harness connector from the combination switch and remove.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• After the work is completed, make sure no system malfunction is detected by air bag warning lamp.
• In case a malfunction is detected by the air bag wa rning lamp, reset with the self-diagnosis function
and delete the memory with CONSULT.
• If a malfunction is still detected after the above operation, perform self-diagnosis to repair malfunc-
tions. Refer to SRC-42, "ADDITIONAL SERVICE WHEN RE PLACING CONTROL UNIT : Special Repair
Requirement".

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951709
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. Information necessary to service t he system safely is included in the SR and SB section 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 which would result in air bag 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 SR section.
• 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 Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009463677
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000009463678
WARNING:
Clean any dust from the front brake and rear brake wi th a vacuum dust collector. Never blow with com-
pressed air.
CAUTION:
• Brake fluid use. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.
• Do not reuse drained brake fluid.
• Do not spill or splash brake fluid on painted su rfaces. Brake fluid may seriously damage paint. Wipe
it off immediately and wash with wa ter if it gets on a painted surface.
• Always clean with new brake fluid when cleaning th e master cylinder, brake caliper and other com-
ponents.
• Do not use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and
cause improper operation.
• Always loosen the brake tube flar e nut with a flare nut wrench.

InspectionINFOID:0000000009463683
BRAKE FLUID LEVEL
• Make sure that the brake fluid level in the reservoir tank is betweenthe MAX and MIN lines.
• Visually check around the reservoir tank for brake fluid leakage.
• If the brake fluid level is excessively low, check the brake system for leakage.
• If brake warning lamp remains illuminated after parking brake pedal is released, check the brake system for brake fluid leakage.
BRAKE LINE
1. Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.
2. Check for brake fluid leakage by depressing brake pedal under a force of 785 N (80 kg-f, 177 lb-f) for approximately 5 seconds
while engine is running.
CAUTION:
If brake fluid leakage occurs around joints, retighten or
replace damaged parts as necessary.
