When the tread is worn down to onesixteenth of an inch (2 mm), tires mustbe replaced to help prevent your vehiclefrom skidding and hydroplaning. Built-intreadwear indicators, or wear bars,which look like narrow strips of smoothrubber across the tread will appear onthe tire when the tread is worn down toone sixteenth of an inch (2 mm).
When the tire tread wears down to thesame height as these wear bars, the tireis worn out and must be replaced.
The tires should also be balancedperiodically. An unbalanced tire andwheel assembly may result in irregulartire wear.
Periodically inspect the tire treads foruneven or excessive wear and remove
objects such as stones, nails or glassthat may be wedged in the treadgrooves.
INSPECTING THE TIRE FOR
DAMAGE
Inspect the tire sidewalls for cracking,cuts, bruises and other signs of damageor excessive wear. If internal damage tothe tire is suspected, have the tiredismounted and inspected in case itneeds to be repaired or replaced. Foryour safety, tires that are damaged orshow signs of excessive wear shouldnot be used because they are morelikely to blow out or fail.
Periodically inspect the tire treads andsidewalls for damage, such as bulges inthe tread or sidewalls, cracks in thetread groove and separation in the treador sidewall. If damage is observed orsuspected, have the tire inspected by atire professional.
Safety Practices
WARNING: If your vehicle isstuck in snow, mud or sand, do notrapidly spin the tires; spinning the tirescan tear the tire and cause anexplosion. A tire can explode in as littleas three to five seconds.
WARNING: Do not spin thewheels at over 34 mph (55 km/h). Thetires may fail and injure a passengeror bystander.
Highway Hazards
No matter how carefully you drive, thereis always the possibility that you could
eventually have a flat tire on thehighway. Drive slowly to the closest safearea out of traffic. This could furtherdamage the flat tire, but your safety ismore important.

If you feel a sudden vibration or ridedisturbance while driving, or you suspectyour tire or vehicle has been damaged,immediately reduce your speed. Drivewith caution until you can safely pull offthe road. Stop and inspect the tires fordamage. If a tire is under-inflated ordamaged, deflate it, remove the wheeland replace it with your spare tire andwheel. If you cannot detect a cause,have the vehicle towed to the nearestrepair facility or tire dealer to have thevehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or potholecan cause the front end of your vehicleto become misaligned or cause damageto your tires. If your vehicle seems topull to one side when you are driving,the wheels could be out of alignment.Have an authorized dealer check thewheel alignment periodically.
Wheel misalignment in the front or therear can cause uneven and rapidtreadwear of your tires and should becorrected by an authorized dealer.
INSPECTING THE WHEEL VALVE
STEMS
Check the valve stems for holes, cracks,or cuts that could permit air leakage.
TIRE ROTATION
WARNING: If the tire label showsdifferent tire pressures for the frontand rear tires and the vehicle has atire pressure monitoring system, thenyou need to update the settings forthe system sensors. Always performthe system reset procedure after tirerotation. If you do not reset the system,it may not provide a low tire pressurewarning when necessary.
Rotating your tires at the recommendedinterval will help your tires wear moreevenly, providing better tire performanceand longer tire life.
Note:If your tires show any unevenwear have the alignment checked byan authorized dealer before rotatingtires.
Note:If you have a dissimilar sparewheel and tire assembly, it is intendedfor temporary use only and should notbe used in a tire rotation.
Note:After having your tires rotated,inflation pressure must be checked andadjusted to the vehicle requirements.

Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS fromfunctioning properly. Always check the TPMSmalfunction telltale after replacing one ormore tires or wheels on your vehicle toensure that the replacement or alternate tiresand wheels allow the TPMS to continue tofunction properly.
