Infiniti G20 (P11). Manual — part 107
Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
NCBR0112
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” 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 composition which is available to INFINITI G20 is as follows:
I
For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt
pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
I
For a side collision
The Supplemental Restraint System consists of side air bag module (located in the outer side of front seat),
satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness,
warning lamp (one of components of air bags for a frontal collision).
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 must be performed
by an authorized INFINITI 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 (except “SEAT BELT PRE-TENSIONER” connector) can be
identified by yellow harness connector.

Precautions for Brake System
NCBR0002
I
Recommended fluid is brake fluid “DOT 3”.
I
Never reuse drained brake fluid.
I
Be careful not to splash brake fluid on painted areas.
I
To clean or wash all parts of master cylinder, disc brake
caliper and wheel cylinder, use clean brake fluid.
I
Never use mineral oils such as gasoline or kerosene. They
will ruin rubber parts of the hydraulic system.
I
Use flare nut wrench when removing and installing brake
tube.
I
Always torque brake lines when installing.
I
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 “Brake Burnishing Procedure”, “ON-VEHICLE
SERVICE”, BR-7.
