 PRECAUTIONS

PRECAUTIONS PFP:00001
A
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” EFS000NG

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
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. C
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. D
● 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. E
● 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. BR
Precautions for Brake System EFS000NL

● Recommended fluid is brake fluid “DOT 3”. G

● Never 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 H
and wheel cylinder, use clean brake fluid.
● Never use mineral oils such as gasoline or kerosene. They will
ruin rubber parts of hydraulic system. I
● Use flare nut wrench when removing and installing brake tube.
● Always torque brake lines when installing.
● Before working, turn ignition switch OFF and disconnect con- SBR686C J
nectors for VDC/TCS/ABS actuator or battery terminals.
● Burnish brake contact surfaces after refinishing or replacing drums or rotors, after replacing pads or lin-
ings, or if a soft pedal occurs at very low mileage. K
Refer to BR-25, "Brake Burnishing Procedure" .
WARNING:
● Clean brake pads and shoes with a waste cloth, then wipe with a dust collector. L

Brake Burnishing Procedure EFS000NV

Burnish brake contact surfaces according to following procedure after refinishing or replacing drums or rotors, K
after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution. L
1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal/foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH). Adjust
brake pedal/foot pressure such that vehicle stopping time equals 3 to 5 seconds. M
3. To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.
