Essential Safety Equipment
SRS Air Bags
Driver Air Bag
The driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag infl ates quickly helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-55 ).
(With Front Passenger Air Bag Deactivation Switch)
The infl ation of the driver's dual-stage air bag is controlled in two energy stages depending
on the driver's seat position. The driver's seat slide position sensor is located under the
driver's seat. The sensor determines whether the driver's seat is forward of or behind a
reference position and sends the seat position to the diagnostic module (SAS unit). The SAS
unit is designed to control the deployment of the driver's air bag depending on how close the
driver's seat is to the steering wheel.
During an impact of moderate severity, the driver's air bag deploys with lesser energy,
whereas during more severe impacts and when the driver's seat is behind the reference
position, it deploys with more energy.
