Tire Pressure Monitor Warning Indicators

NOTE: If a flat tire is replaced with the spare tire, and the flat tire is stored in the cargo area, the low pressure indicator will stay on but the appropriate tire indicator will go off. This prevents the customer from thinking there is a problem with the spare tire. When the flat tire is taken out of the vehicle for repair, the warning light will come on because the system is no longer receiving the signal from the tire's transmitter.

NOTE: If the temperature drops and then rises, tire pressure could decrease just enough to turn on the low pressure and tire(s) indicators, but later increase enough to turn them off. This can be an indication that tires pressures are near the minimum acceptable specification.

NOTE: If the outside temperature is at or below -40°F (-40°C), the system may not function properly.

If the TPMS control unit detects pressure below the lower limit, it turn on the low pressure indicator and the appropriate tire indicator(s) on the multi-information display, as well as the message indicator. When the tire pressure is increased to normal the control unit will turn off the indicators.

When 2 or more tire pressures are low, the low pressure indicator comes on about 5 seconds before the appropriate tire indicator.

If a problem is detected in the system, the TPMS indicator will come on. If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. When the system detects a problem, the TPMS control unit sets a code, but shifts to fail-safe mode, and does not alert the driver to low tire pressures. If the TPMS control unit loses power or fails, the TPMS indicator will come on.

If low tire pressure indicator and multi-information display indicator(s) are lit continuously due to low pressure in one or more tires, adjust tire inflation to proper pressure as indicated on the tire and loading information placard. The light will remain on until tire pressure is properly set. If warning light is still illuminated or the TPMS indicator is lit continuously, there is a problem in the TPM system. See appropriate manufacturer service information.
