The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the vehicle’s tire label.
The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
if the temperature is very cold. ALWAYS check the
pressure in your tires if the TPM lamp is illuminated.
