Your vehicle is equipped with a tire pressure monitoring system (TPMS) that turns on every time you start the engine and monitors the pressure in your tires while driving.
Each tire has its own pressure sensor (not including the spare tire).
If the air pressure of a tire becomes significantly low while driving, the sensor in that tire immediately sends a signal that causes the low tire pressure indicator to come on.
Low Tire Pressure Indicator
When the low tire pressure indicator is on, one or more of your tires is significantly underinflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicleвЂ™s tire information placard.
If you think you can safely drive a short distance to a service station, proceed slowly, and inflate the tire to the recommended pressure shown on the driverвЂ™s doorjamb.
If the tire is flat, or if the tire pressure is too low to continue driving, replace the tire with the compact spare tire.
If you cannot make the low tire pressure indicator go out after inflating the tires to the specified values, have your dealer check the system as soon as possible.
Driving on a significantly under inflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicleвЂ™s handling and stopping ability.
Because tire pressure varies by temperature and other conditions, the low tire pressure indicator may come on unexpectedly.
For example, if you check and fill your tires in a warm area, then drive in extremely cold weather, the tire pressure will be lower than measured and could be underinflated and cause the low tire pressure indicator to come on. Or, if you check and adjust your tire pressure in cooler conditions, and drive into extremely hot conditions, the tire may become overinflated.However, the low tire pressure indicator will not come on if the tires are overinflated.
Although your tire pressure is monitored, you must manually check the tire pressures monthly.
Each tire, including the spare, should be checked monthly when cold, and set to the recommended inflation pressure as specified on the tire information label and in the ownerвЂ™s manual.
Tire PressureMonitoring System (TPMS) Indicator
This indicator comes on and stays on if there is a problem with the tire pressure monitoring system.
If this happens, the system will shut off and no longer monitor tire pressures. Have the system checked by your dealer as soon as possible.
If the low tire pressure indicator or TPMS indicator comes on, the VSA system automatically turns on even if the VSA system is turned off by pressing the VSA OFF switch. If this happens, you cannot turn the VSA system off by pressing the VSA OFF switch again.
When you restart the vehicle with the compact spare tire, the TPMS indicator may also come on and stay on after driving several miles (kilometers).
