TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system isnot a substitute for manually checkingtire pressures. You should periodically checktire pressures using a pressure gauge.Failure to correctly maintain tire pressurescould increase the risk of tire failure, loss ofcontrol, vehicle rollover and personal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
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 from
