Supplemental Restraint System (SRS)

Supplemental Air Bag System
The Supplemental Restraint System (SRS) helps to reduce the risk or severity of injury to the driver in a frontal collision. The SRS consists of:
- Driver side air bag module
- Passenger side air bag module
- Air bag diagnostic monitor
- Wiring harness
- Air bag sliding contact (driver side)
- Air bag warning indicator

The following four steps show how the SRS works:

NOTE: Steps 1-3 take place in a fraction of a second.

1. The sensors in the air bag diagnostic monitor detect a severe frontal impact with the ignition switch in the ON or START position. When the primary crash air bag sensor and the safing air bag sensor in the air bag diagnostic monitor close at the same time, electric current flows to the inflator and ignites the chemicals.
2. The chemicals then rapidly burn in the metal container. The rapid burning produces nitrogen gas and a small amount of dust. The nitrogen gas and dust are cooled and filtered during inflation of the air bags.
3. The inflating air bags split open the trim cover. The air bags then rapidly unfold and inflate in front of the driver and front seat passenger.
4. After inflation, the gas empties through holes in the air bags. The air bags deflate at once.

Electrical System
The SRS can function with the ignition switch in the ON or START positions only. The SRS can function when the driver seat and passenger seat are unoccupied.

Sensors
The primary crash air bag sensor and the safing air bag sensor are incorporated into the air bag diagnostic monitor. The sensors are not serviceable components. The air bag diagnostic monitor, primary crash air bag sensor, and the safing air bag sensor are serviced as a complete assembly.
