Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver's door.See Load Carrying (page 288).
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tirepressure with a tire gauge (includingspare, if equipped). Inflate all tires to theinflation pressure recommended by us.
You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. We recommend the use ofa digital or dial-type tire pressure gaugerather than a stick-type tire pressuregauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
WARNING: Under-inflation is themost common cause of tire failuresand may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rollingresistance, resulting in heat buildup

and internal damage to the tire. It alsomay result in unnecessary tire stress,irregular wear, loss of vehicle controland accidents. A tire can lose up tohalf of its air pressure and not appearto be flat!
Always inflate your tires to the ourrecommended inflation pressure evenif it is less than the maximum inflationpressure information found on the tire.Our recommended tire inflation pressureis found on the Safety ComplianceCertification Label or Tire Label (affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver'sseating position), or Tire Label locatedon the B-pillar or the edge of the driver's
door. Failure to follow the tire pressurerecommendations can cause uneventreadwear patterns and adversely affectthe way your vehicle handles.
Note:Do not reduce tire pressure tochange the ride characteristics of thevehicle. If you do not maintain theinflation pressure at the levels specifiedby us, your vehicle may experience acondition known as shimmy. Shimmy isa severe vibration and oscillation in thesteering wheel after the vehicle travelsover a bump or dip in the road that doesnot dampen out by itself. Shimmy mayresult from significant under-inflation ofthe tires, improper tires (load range, size,or type), or vehicle modifications suchas lift-kits. In the event that your vehicleexperiences shimmy, you should slowlyreduce speed by either lifting off theaccelerator pedal or lightly applying thebrakes. The shimmy will cease as thevehicle speed decreases.
Maximum Inflation Pressure is the tiremanufacturer's maximum permissiblepressure and the pressure at which themaximum load can be carried by the tire.This pressure is normally higher than themanufacturer’s recommended coldinflation pressure which can be foundon the Safety Compliance Certification
Label (affixed to either the door hingepillar, door-latch post, or the door edgethat meets the door-latch post, next tothe driver's seating position), or TireLabel located on the B-pillar or the edgeof the driver's door. The cold inflationpressure should never be set lower thanthe recommended pressure on theSafety Compliance Certification Labelor Tire Label.
When weather temperature changesoccur, tire inflation pressures alsochange. A 10°F (6°C) temperature dropcan cause a corresponding drop of 1 psi(7 kPa) in inflation pressure. Check yourtire pressures frequently and adjustthem to the proper pressure which canbe found on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaningthey are not hot from driving even amile.

Changing Tires With a Tire PressureMonitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire andis not visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (at leastmonthly) using an accurate tire gauge. SeeWhen Inflating Your Tires in this chapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your road tires andsends the tire pressure readings to yourvehicle. You can view the tire pressurereadings through the information display.See General Information (page 119). The lowtire pressure warning light will turn on if thetire pressure is significantly low. Once the
light is illuminated, your tires areunder-inflated and need to be inflated to themanufacturer’s recommended tire pressure.Even if the light turns on and a short timelater turns off, your tire pressure still needsto be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.

Make sure tires are at the proper pressure. See Inflating your tiresin this chapter. After inflating your tires to the manufacturer’srecommended pressure as shown on the Tire Label (located onthe edge of driver’s door or the B-Pillar), the vehicle must be drivenfor at least two minutes over 20 mph (32 km/h) before the lightturns off.

When Inflating Your Tires
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failure tofollow this instruction could result inpersonal injury or death.
When putting air into your tires (such as at agas station or in your garage), the tirepressure monitoring system may not respondimmediately to the air added to your tires.
It may take up to two minutes of driving over20 mph (32 km/h) for the light to turn off afteryou have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring system monitorstire pressure in each pneumatic tire. Whiledriving in a normal manner, a typicalpassenger tire inflation pressure mayincrease about 2–4 psi (14–28 kPa) from acold start situation. If the vehicle is stationaryovernight with the outside temperature
significantly lower than the daytimetemperature, the tire pressure may decreaseabout 3 psi (21 kPa) for a drop of 30°F (17°C)in ambient temperature. This lower pressurevalue may be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If one ormore tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drive thevehicle to the nearest location where air canbe added to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNING: If the tire pressuremonitor sensor becomes damaged it maynot function.
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on this vehicle.
If you get a flat tire when driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have a flat serviced by an authorized dealerin order to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem (page 409). Replace the spare tirewith a road tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.

CD and CD Player Information
Note:CD units play commercially pressed4.7 in (12 cm) audio compact discs only. Dueto technical incompatibility, certainrecordable and re-recordable compact discsmay not function correctly when used in thevehicle’s CD player.
Note: Do not insert CDs with homemadepaper (adhesive) labels into the CD playeras the label may peel and cause the CD tobecome jammed. You should use apermanent felt tip marker rather thanadhesive labels on your homemade CDs. Ballpoint pens may damage CDs. Ask anauthorized dealer for more information.
Note:Do not use any irregularly shapeddiscs or discs with a scratch protection filmattached.
Always handle discs by their edges only. Clean the disc with an approved CD cleaneronly. Wipe it from the center of the disctoward the edge. Do not clean in a circularmotion.
Do not expose discs to direct sunlight or heatsources for extended periods.
MP3 and WMA Track and FolderStructure
Audio systems capable of recognizing andplaying MP3 and WMA individual tracks andfolder structures work as follows:
•There are two different modes for MP3and WMA disc playback: MP3 and WMAtrack mode (system default) and MP3 andWMA folder mode.
•MP3 and WMA track mode ignores anyfolder structure on the MP3 and WMAdisc. The player numbers each MP3 andWMA track on the disc (noted by the MP3or WMA file extension) from T001 to amaximum of T255. The maximum numberof playable MP3 and WMA files may beless depending on the structure of theCD and exact model of radio present.
•MP3 and WMA folder mode representsa folder structure consisting of one levelof folders. The CD player numbers allMP3 and WMA tracks on the disc (notedby the MP3 or WMA file extension) andall folders containing MP3 and WMA files,from F001 (folder) T001 (track) to F253T255.
•Creating discs with only one level offolders helps with navigation through thedisc files.
If you are burning your own MP3 and WMAdiscs, it is important to understand how thesystem reads the structures you create. Whilevarious files may be present (files withextensions other than MP3 and WMA), onlyfiles with the MP3 and WMA extension areplayed; other files are ignored by the system.This enables you to use the same MP3 andWMA disc for a variety of tasks on your workcomputer, home computer and yourin-vehicle system.
