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.

< PRECAUTION >
PRECAUTIONS
• Tighten the brake tube flare nut to the specified torque with
crowfoot (A) and torque wrench (B).
• Always confirm the specified ti ghtening torque when install-
ing the brake pipes.
• Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the parts.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.

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.

BRAKE BOOSTER
BRAKE BOOSTER
InspectionINFOID:0000000009463686
OPERATION
Depress the brake pedal several times at five second intervals with
the engine stopped. Start the engine with the brake pedal fully
depressed. Check that the cl earance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.
VACUUM INSPECTION
Idle the engine for one minute to apply vacuum to the brake booster.
Stop the engine. Depress the brake pedal several times at five sec-
ond intervals until the accumulated vacuum is released to atmo-
spheric pressure. Check that the clearance between brake pedal
and dash lower panel gradually increases (A → B → C) each time
the brake pedal is depressed during this operation.
Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal for
30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.

DISC ROTOR
DISC ROTOR : InspectionINFOID:0000000009463688
APPEARANCE
Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.
RUNOUT
1. Check the wheel bearing axial end play before the inspection. Refer to FAX-6, "Inspection".
2. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.
3. Inspect the runout with a dial gauge, measured at 10 mm (0.39 in) inside the disc edge.
4. Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation
position by one hole at a time if the runout exceeds the limit
value.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When refinishing, use Tool.
THICKNESS
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thick ness is below the wear limit.
