Read Steps 1-4 before proceeding with theprogramming procedure.
Make sure that:
•You set the parking brake.
•The transmission is in park (P).
•The ignition is off.
•You close all vehicle doors.
•You unfasten the driver and frontpassenger seatbelts.
1.Switch the ignition on. Do not start theengine.
2.Immediately start the deactivation orreactivation procedure in Step 3. Onceyou start Step 3, you must complete theprocedure within 30 seconds.
3.For the seating position you are switchingoff or on, fasten then unfasten theseatbelt four times at a moderate speed,ending in the unfastened state. Theseatbelt warning light flashes forconfirmation.
This switches the feature off for that seatingposition if it is currently on.
This switches the feature on for that seatingposition if it is currently off.
CHECKING THE SEATBELTS
Check the seatbelts and child restraintsperiodically to make sure they work properlyand are not damaged. Make sure there areno nicks, tears or cuts. Replace if necessary.
Check the following seatbelt assemblies aftera crash.
•Retractors.
•Buckles.
•Front seatbelt buckle assemblies.
•Shoulder belt height adjusters.
•Shoulder belt guide on seat backrest.
•Child restraint LATCH and tether anchors.
•Attaching hardware.
Read the child restraint manufacturer'sinstructions for additional inspection andmaintenance information specific to the childrestraint.
We recommend that all seatbelt assembliesin use in vehicles involved in a crash bereplaced. However, if the crash was minorand an authorized dealer finds that the beltsdo not show damage and continue tooperate properly, they do not need to bereplaced. Seatbelt assemblies not in useduring a crash should also be checked andreplaced if either damage or improperoperation is noted.
Properly care for seatbelts. See CleaningSeatbelts (page 434).
SEATBELT EXTENSIONS
WARNING: Persons who fit into thevehicle's seatbelt should not use anextension. Unnecessary use could resultin serious personal injury in the event of acrash.

HOW DO THE FRONT AIRBAGS
WORK
The driver and front passenger airbagsdeploy during significant frontal and nearfrontal crashes.
The driver and passenger front airbag systemconsists of:
•Driver and passenger airbag modules.
•Front passenger sensing system.
•Crash sensors and monitoring systemwith readiness indicator. See CrashSensors and Airbag Indicator (page 68).
The airbags are a supplemental restraintsystem and are designed to work with theseatbelts to help protect the driver and rightfront passenger from certain upper bodyinjuries. Airbags do not inflate slowly; thereis a risk of injury from a deploying airbag.
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 rapidly uponactivation. After airbag deployment, it isnormal to notice a smoke-like, powderyresidue or smell the burnt propellant. Thismay consist of cornstarch, talcum powder (tolubricate the bag) or sodium compounds (forexample, baking soda) that result from thecombustion process that inflates the airbag. Small amounts of sodium hydroxide may bepresent which may irritate the skin and eyes,but none of the residue is toxic.
Contact with a deploying airbag may causeabrasions or swelling. Temporary hearingloss is also a possibility as a result of thenoise associated with a deploying airbag.
Because airbags must inflate rapidly and withconsiderable force, there is the risk of deathor serious injuries such as fractures, facialand 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 that occupantsbe properly restrained as far away from theairbag module as possible while maintainingvehicle control.
Routine maintenance of the airbags is notrequired.
HOW DO THE SIDE AIRBAGS
WORK
WARNING: Do not place objects ormount equipment on or near the airbagcover, on the side of the front or rearseatbacks, or in areas that may come intocontact with a deploying airbag. Failure tofollow these instructions may increase therisk of personal injury in the event of acrash.

WARNING: Modifying or addingequipment to the front of your vehiclecould affect the performance of the airbagsystem, increasing the risk of injury. Thisincludes the hood, bumper system, frame,front body structure, tow hooks, hood pins,push bar and snowplows.
Your vehicle has a collection of crash andoccupant sensors. These sensors provideinformation to the restraints control modulewhich activates the following:
•Front seatbelt pretensioners.
•Adaptive steering column.
•Driver airbag.
•Passenger airbag.
•Seat mounted side airbags.
•Safety Canopy.
Based on the type of crash, the restraintscontrol module deploys the appropriatesafety devices.
The restraints control module also monitorsthe readiness of the above safety devicesplus the crash and occupant sensors. Thereadiness of the safety system is indicatedby a warning indicator light in the instrumentcluster or by a backup tone if the warninglight is not working. Routine maintenance ofthe airbag is not required.
A difficulty with the system is indicated byone or more of the following:

WHAT IS DISTANCE TO EMPTY
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank. Changes in driving pattern cancause the value to not only decrease but alsoincrease or stay constant for periods of time.
ENGINE COOLANT TEMPERATURE
GAUGE
Indicates the engine coolant temperature.
ENGINE OIL PRESSURE GAUGE
Indicates the engine oil pressure.
Note:This is a configurable gauge.

WHAT IS THE CABIN AIR FILTER
The cabin air filter improves the quality of airin your vehicle by trapping dust, pollen andother particles.
REPLACING THE CABIN AIR FILTER
Replace the filter at regular intervals. SeeScheduled Maintenance (page 529).
Note:Make sure you have a cabin air filterinstalled at all times. This prevents foreignobjects from entering the system. Runningthe system without a filter in place couldresult in degradation or damage to thesystem.
Note:Using an aftermarket cabin air filtercould reduce cabin air filtration and climatecontrol performance.
