CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and childsafety seat systems periodically to makesure they work properly and are notdamaged. Inspect the vehicle and childrestraint seatbelts to make sure there areno nicks, tears or cuts. Replace ifnecessary. All vehicle seatbelt assemblies,including retractors, buckles, front seatbeltbuckle assemblies, buckle supportassemblies (slide bar-if equipped),shoulder belt height adjusters (ifequipped), shoulder belt guide on seatbackrest (if equipped), child safety seatLATCH and tether anchors, and attachinghardware, should be inspected after acrash. Read the child restraintmanufacturer's instructions for additionalinspection and maintenance informationspecific to the child restraint.
We recommend that all seatbeltassemblies in use in vehicles involved in acrash be replaced. However, if the crashwas minor and an authorized dealer findsthat the belts do not show damage andcontinue to operate properly, they do notneed to be replaced. Seatbelt assembliesnot in use during a crash should also beinspected and replaced if either damageor improper operation is noted.
Properly care for seatbelts. See VehicleCare (page 291).
SEATBELT EXTENSIONS
WARNING: Persons who fit intothe vehicle's seatbelt should not use anextension. Unnecessary use could resultin serious personal injury in the event ofa crash.
WARNING: Only use extensionsprovided free of charge by our dealers.The dealer will provide an extensiondesigned specifically for this vehicle,model year and seating position. The useof an extension intended for anothervehicle, model year or seating positionmay not offer you the full protection ofyour vehicle's seatbelt restraint system.
WARNING: Never use seatbeltextensions to install child restraints.
WARNING: Do not use a seatbeltextension with an inflatable seatbelt.
WARNING: Do not use extensionsto change the way the seatbelt fitsacross the torso, over the lap or to makethe seatbelt buckle easier to reach.
If, because of body size or driving position,it is not possible to properly fasten theseatbelt over your lap and shoulder, anextension that is compatible with theseatbelts is available free of charge fromour dealers. Only use our seatbeltextensions made by the original equipmentseatbelt manufacturer with our seatbelts.Ask your authorized dealer if your extensionis compatible with your vehicle restraintsystem.

While the system is designed to helpreduce serious injuries, contact with adeploying airbag may also cause abrasionsor swelling. Temporary hearing loss is alsoa possibility as a result of the noiseassociated with a deploying airbag.Because airbags must inflate rapidly andwith considerable force, there is the risk ofdeath or serious injuries such as fractures,facial and eye injuries or internal injuries,particularly to occupants who are notproperly restrained or are otherwise out ofposition at the time of airbag deployment.Thus, it is extremely important thatoccupants be properly restrained as faraway from the airbag module as possiblewhile maintaining vehicle control.
Routine maintenance of the airbags is notrequired.
DRIVER AND PASSENGER
AIRBAGS
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.
The driver and front passenger airbags willdeploy during significant frontal and nearfrontal crashes.
The driver and passenger front airbagsystem consists of:
•Driver and passenger airbag modules.
•Front passenger sensing system.
· Crash sensors and monitoringsystem with readiness indicator.See Crash Sensors and AirbagIndicator (page 56).
Proper Driver and Front PassengerSeating Adjustment
WARNING: National HighwayTraffic Safety Administration (NHTSA)recommends a minimum distance of atleast 10 in (25 cm) between anoccupant's chest and the driver airbagmodule.
To properly position yourself away fromthe airbag:
•Move your seat to the rear as far as youcan while still reaching the pedalscomfortably.
•Recline the seat slightly (one or twodegrees) from the upright position.

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.
