CRASH SENSORS AND AIRBAG INDICATOR
WARNING: Modifying or adding equipment to the front end of
your vehicle (including frame, bumper, front end body structure
and tow hooks) may affect the performance of the airbag system,
increasing the risk of injury. Do not modify the front end of your
vehicle.
Your vehicle has a collection of crash and occupant sensors which
provide information to the restraints control module which deploys
(activates) the front safety belt pretensioners, rear inflatable safety belts,
driver airbag, passenger airbag, passenger knee airbag, seat mounted side
airbags, and the Safety Canopy. Based on the type of accident (frontal
impact, side impact or rollover) the restraints control module will deploy
the appropriate safety devices.
The restraints control module also monitors the readiness of the above
safety devices plus the crash and occupant sensors. The readiness of the
safety system is indicated by a warning indicator light in the instrument
cluster or by a backup tone if the warning light is not working. See the
Instrument Cluster chapter. Routine maintenance of the airbag is not
required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light will either flash or stay lit.
• The readiness light will not illuminate immediately after the
ignition is turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem or light is repaired.
If any of these things happen, even intermittently, have the supplemental
restraint system serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a crash.
The safety belt pretensioners, rear inflatable safety belts and the airbag
supplemental restraint system are designed to activate when the vehicle
sustains frontal or sideways deceleration sufficient to cause the restraints
control module to deploy a safety device or when a certain likelihood of
a rollover event is detected by the rollover sensor.
The fact that the safety belt pretensioners or airbags did not activate for
both front seat occupants in a crash does not mean that something is
wrong with the system. Rather, it means the restraints control module
determined the accident conditions (such as crash severity, belt usage)
were not appropriate to activate these safety devices.
