Tire Pressure Monitor Warning Light

NOTE: The tire pressure warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by temperature. In this case, adjusting the tire pressure will turn off the warning light.

NOTE: If warning light turned on due to very low outside temperatures (such as in winter) causing decreases in tire pressure, adjust pressure to a higher pressure suitable to cold conditions. Tire pressure decreases by about 1.45 psi (10 kPa) for every 50°F (10°C) drop in ambient temperature.

When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure (including spare tire) and adjust as necessary. The warning light should turn off within a few minutes. If the warning light is still on even though the tire pressure is correctly adjusted, the tire could be punctured. Repair as necessary. If the warning light turns on within several hours after adjusting the tire pressure, the tire may have a slow air leak. Repair as necessary. If the warning light stays on or blinks, there is a malfunction in the TPM system. See appropriate manufacturer service information.

Under the following conditions, the system may not function properly:

The areas, facilities or devices that use similar radio wave frequencies are located in the vicinity of the vehicle.
A radio device of similar frequency is used near the vehicle.
A lot of snow or ice is stuck to the vehicle, especially around the wheels or wheel housings.
Tires and wheels are installed that are not equipped with a tire pressure sensor.
Snow tires or tire chains are used.
The battery of the sensor has been depleted.
Wheels other than manufacturer factory wheels are used. If any other wheels than the specified ones are used, the system may not function properly because the radio waves are differently transmitted from the tire pressure sensor.
Radio waves from the air pressure sensor installed on the spare tire cannot be received. If this problem has occurred, rotate spare tire 90 degrees and recheck system.
Depending on the tire type, the system may not function properly even though the specified wheels are used.
Using a different type of tire in combination with genuine tires.
If system was initialized with tire pressures which are not the specified values.
