PRINCIPLE OF OPERATION
WARNING: Airbags do not inflateslowly or gently, and the risk of injuryfrom a deploying airbag is the greatestclose to the trim covering the airbagmodule.
WARNING: All occupants of yourvehicle, including the driver, shouldalways properly wear their seatbelts,even when an airbag supplementalrestraint system is provided. Failure toproperly wear your seatbelt couldseriously increase the risk of injury ordeath.
WARNING: Even with advancedrestraints systems, properly restrainchildren 12 and under in a rear seatingposition. Failure to follow this couldseriously increase the risk of injury ordeath.
WARNING: Do not place your armson the airbag cover or through thesteering wheel. Failure to follow thisinstruction could result in personal injury.
WARNING: Keep the areas in frontof the airbags free from obstruction. Donot affix anything to or over the airbagcovers. Objects could become projectilesduring airbag deployment or in a suddenstop. Failure to follow this instructioncould result in personal injury or death.
WARNING: Airbags can kill or injurea child in a child restraint. Never place arear-facing child restraint in front of anactive airbag. If you must use aforward-facing child restraint in the frontseat, move the seat upon which the childrestraint is installed all the way back.
WARNING: Do not attempt toservice, repair, or modify thesupplementary restraint system orassociated components. Failure tofollow this instruction could result inpersonal injury or death.
WARNING: Several airbag systemcomponents get hot after inflation. Toreduce the risk of injury, do not touchthem after inflation.
WARNING: If a supplementaryrestraint system component hasdeployed, it will not function again. Havethe system and associated componentsinspected as soon as possible. Failure tofollow this instruction could result inpersonal injury or death.
The airbags are a supplemental restraintsystem and are designed to work with theseatbelts to help protect the driver andright front passenger from certain upperbody injuries. Airbags do not inflate slowly;there is a risk of injury from a deployingairbag.
Note:You will hear a loud bang and see acloud of harmless powdery residue if anairbag deploys. This is normal.
The airbags inflate and deflate rapidlyupon activation. After airbag deployment,it is normal to notice a smoke-like, powderyresidue or smell the burnt propellant. Thismay consist of cornstarch, talcum powder(to lubricate the bag) or sodiumcompounds (for example, baking soda)that result from the combustion processthat inflates the airbag. Small amounts ofsodium hydroxide may be present whichmay irritate the skin and eyes, but none ofthe residue is toxic.

The system consists of the following:
•A label or embossed side panelindicating that your vehicle has sideairbags.
•Side airbags inside the driver and frontpassenger seat backrests.
·Crash sensors and monitoringsystem with a readinessindicator. See Crash Sensorsand Airbag Indicator (page 56).

DRIVER AND PASSENGER
KNEE AIRBAGS
WARNING: To reduce risk of injury,do not obstruct or place objects in thedeployment path of the airbag.
WARNING: Close the glove boxdoor when your vehicle is moving. Failureto follow this instruction could reducethe effectiveness of the passenger kneeairbag and increase the risk of injury in acrash.
A driver knee airbag is located under orwithin the instrument panel. A passengerknee airbag is located within or under theglove box door. During a crash, therestraints control module may activate thedriver and passenger knee airbags basedon crash severity and occupant conditions.Under certain crash and occupantconditions, the driver and passenger kneeairbag may deploy but the driver frontairbag may not activate. As with front andside airbags, it is important to be properlyseated and restrained to reduce the risk ofdeath or serious injury.
Make sure the knee airbags areoperating properly. See CrashSensors and Airbag Indicator(page 56).

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or addingequipment to the front of your vehiclecould affect the performance of theairbag system, increasing the risk ofinjury. This includes the hood, bumpersystem, frame, front body structure, towhooks, hood pins, push bar andsnowplows.
Your vehicle has a collection of crash andoccupant sensors. These sensors provideinformation to the restraints controlmodule which activates the following:
•Driver airbag.
•Passenger airbag.
•Front seatbelt pretensioners.
•Adaptive steering column.
•Knee airbag(s).
•Seat mounted side airbags.
•Safety Canopy airbags.
Based on the type of crash, the restraintscontrol module deploys the appropriatesafety devices.
The restraints control module alsomonitors the readiness of the above safetydevices plus the crash and occupantsensors. The readiness of the safetysystem is indicated by a warning indicatorlight in the instrument cluster or by abackup tone if the warning light is notworking. Routine maintenance of theairbag is not required.
A difficulty with the system is indicated byone or more of the following:
The readiness light will notilluminate immediately after youswitch the ignition on.
•The readiness light either flashes orstays lit.
•You will hear a series of five tones. Thetone pattern repeats periodically untilthe problem, the light or both arerepaired.
If any of these things happen, evenintermittently, have the supplementalrestraint system serviced at an authorizeddealer immediately. Unless serviced, thesystem may not function properly in theevent of a crash.
The seatbelt pretensioners and the frontairbag supplemental restraint system aredesigned to activate when the vehiclesustains frontal deceleration sufficient tocause the restraints control module todeploy a safety device.
The fact that the seatbelt pretensionersor front airbags did not activate for bothfront seat occupants in a crash does notmean that something is wrong with thesystem. Rather, it means the restraintscontrol module determined the accidentconditions (crash severity, belt usage)were not appropriate to activate thesesafety devices.
•The front airbags activate only infrontal and near-frontal crashes. Frontairbags may activate in rollovers, sideimpacts or rear impacts if the crashcauses sufficient frontal deceleration.
•The seatbelt pretensioners activate infrontal, near-frontal and side crashes,and in rollovers.
•The knee airbag(s) may deploy basedon crash severity and occupantconditions.
