CRASH SENSORS AND AIRBAG INDICATOR
WARNING: Modifying or adding equipment to the front end of
the 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 the vehicle.
The vehicle has a collection of crash and occupant sensors which provide
information to the Restraints Control Module (RCM) which deploys
(activates) the front safety belt pretensioners, driver airbag, passenger
airbag, seat mounted side airbags, and the Safety Canopy威. 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. Refer to
Warning lamps and Indicators in 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 and/or light are 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 collision.
The safety belt pretensioners and the airbag supplemental restraint
system is designed to activate when the vehicle sustains longitudinal or
lateral deceleration sufficient to cause the restaints control module to
deploy a safety device or when a certain likelihood of a rollover event is
detected by the rollover sensor.
