Description & Operation

WARNING: To avoid injury from accidental air bag deployment or seat belt tensioner triggering, read and carefully follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS .

Supplemental Restraint System (SRS) is designed to protect driver and front passenger by activating when vehicle receives a sufficient front-end impact. System includes driver-side air bag, passenger-side air bag, driver and passenger-side seat belt tensioners, SRS unit (with internal safing and impact sensors) and cable reel. See Figure .

The main circuit in SRS unit senses and judges force of impact and, if necessary, ignites inflator charges in air bag assemblies, causing air bags to inflate. If battery voltage is too low or power is disconnected due to impact, voltage regulator and back-up power circuit keeps voltage at a constant level.

During a frontal collision, SRS unit activates driver-side and passenger-side seat belt tensioners, causing them to instantly and firmly retract seat belts. This increases seat belt effectiveness.
