Supplemental Restraint System (SRS) “AIR
BAG”
NMBR0122
The Supplemental Restraint System such as “AIR BAG” used along with a seat belt, helps to reduce the risk
or severity of injury to the driver and front passenger for certain types of collision. The SRS system composi-
tion which is available to NISSAN MODEL S15 is as follows:
The Supplemental Restraint System consists of driver air bag module (located in the center of the steering
wheel), front passenger air bag module (located on the instrument panel on passenger side), a diagnosis
sensor unit, warning lamp, wiring harness and spiral cable.
Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
I
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 should be per-
formed by an authorized NISSAN dealer.
I
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 RS section.
I
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 with yellow harness connector.

Precautions for Brake System
NMBR0002
I
Use brake fluid “DOT 3”.
I
Never reuse drained brake fluid.
I
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.
I
To clean master cylinder parts, disc brake caliper parts or
wheel cylinder parts, use clean brake fluid.
I
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
tubes.
I
Always torque brake lines when installing.
WARNING:
I
Clean brakes with a vacuum dust collector to minimize
risk of health hazard from powder caused by friction.
