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 FLUIDPFP:KN100
Checking Brake Fluid LevelBFS000BI

Make sure that a brake fluid level in reservoir tank is within the
standard (between MAX and MIN lines).

Visually check around reservoir tank for fluid leakage.

If fluid level is excessively low, check brake system for leakage.

Release parking brake pedal and see if brake warning lamp
goes off. If not, check brake system for fluid leakage.
Drain and RefillBFS000BJ
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Do not reuse drained brake fluid.

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

Before working, turn ignition switch OFF and disconnect electrical connector of ABS actuator and
electric unit (control unit) or battery cables.
1. Connect a vinyl tube to bleed valve.
2. Depress brake pedal, loosen bleed valve, and gradually remove
brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
brake pedal until it stops. Tighten bleed valve. Release brake
pedal. Repeat this process a few time, them pause to and new
brake fluid to master cylinder. Continue until new brake fluid
flows out.
5. Bleed air. Refer to BR-10, "
Bleeding Brake System" .
