The most effective occupant restraint

system yet developed for use in

production vehicles is the seat belt. In

some cases, however, the protective

effect of a seat belt can be further

The driver airbag is located in the

steering wheel hub. The passenger front

airbag is located in the dashboard ahead

of the front passenger

The side impact airbags are located in

the doors. In conjunction with wearing

the seat belts with emergency

tensioning retractors, the airbags can

provide increased protection for the

driver and front passenger in certain

major frontal (for front airbags), and

side impacts (for side impact airbags).

The operational readiness of the airbag

system is verified by the indicator lamp

"SRS" in the instrument cluster when

turning the electronic key in steering

lock to position 1 or 2. If no fault is

detected, the lamp will go out after

approximately 4 seconds; after the lamp

goes out, the system continues to

monitor the components and circuitry

of the airbag system and will indicate a

malfunction by coming on again.

The following system components are

monitored or undergo a self-check:

crash-sensor(s), airbag ignition circuits,

front seat belt buckles, emergency

tensioning retractors, seat sensor.

Initially, when the electronic key is

turned from steering lock position 0 to

positions 1 or 2, malfunctions in the

crash-sensor are detected and

indicated (the "SRS" indicator lamp

stays on longer than 4 seconds).

In the operational mode, after the

indicator lamp has gone out following
