{Warning
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie⇣down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
This vehicle is equipped with one ormore airbags. SeeAirbag System055.Airbagsaredesignedtoinflateif the impact exceeds the specificairbag system's deploymentthreshold. Deployment thresholdsare used to predict how severe acrash is likely to be in time for theairbags to inflate and help restrainthe occupants. The vehicle haselectronic sensors which help theairbag system determine theseverity of the impact. Deploymentthresholds can vary with specificvehicle design.
Frontal airbags are designed toinflate in moderate to severe frontalor near-frontal crashes to helpreduce the potential for severeinjuries mainly to the driver or frontoutboard passenger head andchest.
Whether the frontal airbags will orshould deploy is not based primarilyon how fast the vehicle is traveling.
It depends largely on what you hit,the direction of the impact, and howquickly the vehicle slows down.
Frontal airbags may inflate atdifferent crash speeds depending onwhether the vehicle hits an objectstraight on or at an angle, andwhether the object is fixed ormoving, rigid or deformable, narrowor wide.
Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.
Seat-mounted side impact airbags,if equipped, are designed to inflatein moderate to severe side crashesdepending on the location of theimpact. Seat-mounted side impactairbags are not designed to inflate infrontal impacts, near-frontal impacts,rollovers, or rear impacts.Aseat-mountedsideimpactairbagis intended to inflate on the side ofthe vehicle that is struck.
The vehicle may or may not beequipped with roof-rail airbags.Roof-rail airbags are designed toinflate in moderate to severe sidecrashes depending on the location

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation0321.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, frontsensors, or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0269for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect the
vehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any otherreason, call Customer Assistance.SeeCustomer AssistanceOffices0314.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light099.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the
airbags, seeWhere Are the
Airbags?057.Seeyourdealer

The power outlet is not designed forthe following, and may not workproperly if they are plugged in:
.Equipment with high initial peakwattage, such ascompressor-driven refrigeratorsand electric power tools.
.Other equipment requiring anextremely stable power supply,such asmicrocomputer-controlledelectric blankets and touchsensor lamps.
.Medical equipment.
Cigarette Lighter
If equipped with a cigarette lighter,to heat push it in all the way and letgo. When it is ready for use, it willpop back out by itself.
Do not use the lighter to plug inaccessory devices. Use the poweroutlets provided.
Caution
Holding a cigarette lighter in while
it is heating does not let the
lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.
Ashtrays
If equipped with a removableashtray, it can be placed into thefront floor console cupholder. Openthe cover to use.
Caution
If papers, pins, or other
flammable items are put in the

them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges cansignal that something is wrongbefore it becomes serious enoughto cause an expensive repair orreplacement. Paying attention to thewarning lights and gauges couldprevent injury.
Some warning lights come on brieflywhen the engine is started toindicate they are working. Whenone of the warning lights comes onand stays on while driving, or whenone of the gauges shows there maybe a problem, check the section thatexplains what to do. Waiting to dorepairs can be costly and evendangerous.

Voltmeter Gauge
When the engine is not running, butthe ignition is on, this gauge showsthe battery's state of charge inDC volts.
When the engine is running, thegauge shows the condition of thecharging system. Readings betweenthe low and high warning zonesindicate the normal operating range.
Readings in the low warning zonemay occur when a large number ofelectrical accessories are operatingin the vehicle and the engine is leftat an idle for an extended period.This condition is normal since the
charging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.
The vehicle can be only driven for ashort time with the reading in eitherwarning zone. If it must be driven,turn off all unnecessaryaccessories.
Readings in either warning zoneindicate a possible problem in theelectrical system. Have the vehicleserviced as soon as possible.
