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 Cover

AFS0038M

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

Precautions for Brake System

AFS0016P

●

Recommended fluid is brake fluid “DOT 3”.

●

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 areas, wash it away with water immediately.

●

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

●

Never 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 torque.

●

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and control unit or battery negative ter-
minal.

●

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-32, "BRAKE BURNISHING PROCEDURE"

WARNING:

●

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