PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS006NT
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.
WA RN ING:
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 SystemEFS006J2
Refill using recommended brake fluid. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted sur-
faces of body immediately wipe it off with cloth and then wash it away with water.
To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use a flare nut wrench when removing a brake tube and use a
flare nut torque wrench when installing a brake tube.
When installing brake tubes and hoses, be sure to check torque.
Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or the bat-
tery cable from the negative terminal.
Burnish the new braking surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer toBR-29, "
Brake Burnishing
Procedure" .SBR6 86 C

CHECKING BRAKE FLUID LEVEL
Make sure the fluid level in the reservoir tank is within the stan-
dard (between MAX and MIN lines).
Visually check around the reservoir tank for fluid leakage.
If fluid level is excessively low, check brake system for fluid leak-
age.
Release parking brake lever and see if brake warning lamp goes
off. If not, check brake system for fluid leakage.
Drain and RefillEFS006J9
CAUTION:
Refill using recommended brake fluid. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Never 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 areas, immediately wipe them with cloth and wash it away with water.
Before working, disconnect connectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke
and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the brake pedal. Repeat the same procedure
for each wheel.
5. Bleed air. Refer to BR-10, "
Bleeding Brake System" .
