PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS0028A
The Supplemental Restraint System such as “AIR 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 whether 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 inoperative, 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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Procedures without Cowl Top CoverAFS0038B
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemAFS001MQ
Recommended fluid is brake fluid “DOT 3”.
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 clean brake fluid.
Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use flare nut wrench when removing and installing brake tube.
When installing brake piping, be sure to check torque.
Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
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-25, "
BRAKE BURNISHING PROCEDURE" .
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.

ADJUSTMENT
1. Loosen stop lamp switch and ASCD cancel switch (or brake
switch) by turning it counterclockwise by 45 °.
2. Loosen lock nut (A) on input rod, then rotate input rod to set pedal to the specified height, and tighten lock nut (A).
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch and ASCD cancel switch (or brake switch) until its threaded end con-
tacts stopper rubber.
4. With the threaded end of stop lamp switch and ASCD cancel switch (or brake switch) contacting stopper rubber, rotate switch
clockwise by 45 ° to secure.
CAUTION:

and threaded end of stop lamp switch and ASCD cancel
switch (or brake switch) is within the standard.
5. Check pedal play. CAUTION:
Make sure that stop lamps go off when pedal is released.
6. Start engine to check brake pedal depressed height.

LEVEL CHECK
Make sure the fluid level in reservoir tank is within the standard
(between MAX and MIN lines).
Visually check around reservoir tank for fluid leaks.
If fluid level is excessively low, check brake system for leaks.
If brake warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillAFS001MW
CAUTION:
Refill with new brake fluid “DOT3”.
Do not reuse drained brake fluid.
Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint, so
when splashing it, immediately wipe off the area and wash away with water.
Before servicing, disconnect actuator connector or battery negative cable.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
Bleed Air. Refer to BR-10, "
