Customer Action RequiredPossible CauseLow Tire PressureWarning Light
Make sure tires are at the proper pres-sure. See Inflating your tires in thischapter. After inflating your tires to themanufacturer’s recommended pressureas shown on the Tire Label, located onthe edge of driver door or the B-Pillar, thevehicle must be driven for at least twominutes over 20 mph (32 km/h) beforethe light turns off.

When Inflating Your Tires
When putting air into your tires, such as ata gas station or in your garage, the tirepressure monitoring system may notrespond immediately to the air added toyour tires.
It may take up to two minutes of drivingover 20 mph (32 km/h) for the light to turnoff after you have filled your tires to therecommended inflation pressure.

How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. When driving in a normal manner, atypical passenger tire inflation pressuremay increase about 2–4 psi (14–28 kPa)from a cold start situation. If the vehicle isstationary overnight with the outsidetemperature significantly lower than thedaytime temperature, the tire pressure maydecrease about 3 psi (21 kPa) for a drop of30°F (17°C) in ambient temperature. Thislower pressure value may be detected bythe tire pressure monitoring system asbeing significantly lower than therecommended inflation pressure andactivate the system warning light for lowtire pressure. If the low tire pressurewarning light is on, visually check each tireto verify that no tire is flat. If one or moretires are flat, repair as necessary. Checkthe air pressure in the road tires. If any tireis under-inflated, carefully drive the vehicleto the nearest location where air can beadded to the tires. Inflate all the tires tothe recommended inflation pressure.
Tire Pressure Monitoring System ResetProcedure
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance CertificationLabel (on the door hinge pillar,door-latch post or the door edge thatmeets the door-latch post, next to thedriver seat) or the Tire Label on theB-Pillar or the edge of the driver door.
Note:You need to perform the tire pressuremonitoring system reset procedure aftereach tire rotation.
To provide the vehicle's load carryingcapability, some vehicles require differentrecommended tire pressures in the fronttires as compared to the rear tires. The tirepressure monitoring system on thesevehicles illuminate the low tire pressurewarning light at two different pressures:one for the front tires and one for the reartires.
Since tires need to be rotated to provideconsistent performance and maximum tirelife, the tire pressure monitoring systemneeds to know when the tires are rotatedto determine which set of tires are on thefront and which are on the rear. With thisinformation, the system can detect andproperly warn of low tire pressures.
System reset tips:
•To reduce the chances of interferencefrom another vehicle, perform thesystem reset procedure at least 3 ft(1 m) away from another vehicleundergoing the system reset procedureat the same time.
•Do not wait more than two minutesbetween resetting each tire sensor orthe system can time-out and you haveto repeat the entire procedure on allfour wheels.
•A double horn sounds indicating theneed to repeat the procedure.
Performing the System Reset Procedure- Single Rear Wheel
Read the entire procedure beforeattempting.
1.Drive the vehicle above 20 mph(32 km/h) for at least two minutes,then park in a safe location where youcan easily get to all four tires and haveaccess to an air pump.
2.Place the ignition in the off position andkeep the key in the ignition.
