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 115). 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 information displayas a tire pressure gauge. Failure to followthis instruction could result in personal injuryor 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 pressure monitorsensor becomes damaged it may notfunction.
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 the 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 tirepressure monitoring system sensors. SeeTire Pressure Monitoring System (page 359).Replace the spare tire with a road tire assoon as possible. During repairing orreplacing of the flat tire, have an authorizeddealer inspect the tire pressure monitoringsystem sensor for damage.
