PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000BB
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 Brake SystemBFS000BC

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 or DOT 4”. Refer to MA-14, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed
on painted surfaces of body, immediately wipe it off and them wash it away with water immediately.

To clean or wash all parts of master cylinder, disc brake caliper, use clean 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 torque wrench when installing brake tube.

When installing brake tube, be sure to check torque.

Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery cables.

Burnish the brake contact surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low
mileage. Refer to BR-32, "
BRAKE BURNISHING PROCE-
DURE" (Front disc brake), BR-39, "BRAKE BURNISHING
PROCEDURE" (Rear disc brake).
WARNING:

Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

BRAKE PEDAL

BRAKE PEDALPFP:46501
Inspection and AdjustmentBFS000BG
Play and clearance inspection between brake pedal and floor panel with pedal depressed.

Check brake pedal height from dash lower panel (1).

Adjust height referring to the following specifications.
ADJUSTMENT
1. Loosen stop lamp switch, brake switch and/or ASCD cancel
switch by turning it counterclockwise by 45°.
2. Loosen lock nut “A” on input rod, then rotate input rod to set,
brake pedal to the specified height, and tighten lock nut “A”.
Refer to BR-22, "
COMPONENTS" .
CAUTION:
Make sure the threaded end of input rod stays inside clevis.
3. With pedal pulled and held by hand, press stop lamp switch,
brake switch and/or ASCD cancel switch until its threaded end
contacts bracket.
4. With threaded end of stop lamp switch, brake switch and/or
ASCD cancel switch contacting bracket, rotate switch clockwise
by 45° to secure.
CAUTION:

Make sure that the clearance “C” between bracket and
end of stop lamp switch, brake switch and/or ASCD can-
cel switch is within the standard.

When locking stop lamp switch and ASCD cancel switch,
pull brake pedal to avoid moving toward the direction
where switches are being pressed.
5. Check the pedal play.
CAUTION:
Make sure that stop lamps goes off when pedal is released.
6. Start engine to check brake pedal depressed height.
