PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612918
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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct 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 “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001612920
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000001327604
 Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
 Recommended fluid is brake fluid “DOT 3”. MA-9, "
Fluids and Lubricants".
 Do not reuse drained brake fluid.
 Be careful not to splash brake fluid on painted areas.
 To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
 Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
 Use a flare nut crowfoot and torque wrench when installing brake
tube.
 When installing brake piping, be sure to check torque.
 Before working, turn ignition switch OFF and disconnect connec- tors for ABS actuator and electric unit (control unit) or battery neg-
ative terminal.
 Burnish the brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-23, "
Brake Burnishing Procedure" (Front disc brake),
BR-29, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
 Clean brake pads and shoes with a waste cl oth, then clean with a dust collector.

terclockwise.
 The brake tubes and hoses is an important safety pa rt. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.

BRAKE BOOSTER
BRAKE BOOSTER
On-Vehicle ServiceINFOID:0000000001327621
OPERATING CHECK
With engine stopped, change the vacuum to the atmospheric pres-
sure by depressing brake pedal several times. Then with brake
pedal fully depressed, start engine and when the vacuum pressure
reaches the standard, make sure the clearance between brake pedal
and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK
 Run engine at idle for approximately 1 minute, and stop it afterapplying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure dis-
tance between brake pedal and floor panel gradually increases.
 Depress brake pedal while engine is running, and stop engine with
pedal depressed. The pedal stroke should not change after holding
pedal down for 30 seconds.
CAUTION:
Depressing brake pedal is interval is approximately at intervals
5 seconds.
