How The Airbag System Works
•
A crash sensor in the occupant compartment deter-
mines if a frontal impact is severe enough to require
the airbag. The sensor will not detect side, roll over, or
rear impacts. The crash sensor is connected to the
diagnostic unit and to the airbag/inflator unit.
•
The Diagnostic Unit monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in the START or RUN position. These include
all of the items listed above except the knee bolster, the
instrument panel, and the steering wheel and column.
The Diagnostic Unit also turns on the AIRBAG light in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously.
•
The Airbag/Inflator Units are in the center of the
steering wheel and in the instrument panel. The words
SRS/AIRBAG are embossed on the airbag covers.
WARNING!
Ignoring the AIRBAG light in your instrument panel
could mean you won’t have the airbags to protect
you in a collision. If the light does not come on, stays
on after you start the vehicle, or if it comes on as you
drive, have the airbag system checked right away.
