Tire Pressure Monitor Warning Indicators

NOTE: As ambient temperature decreases by 6°C (10°F), tire pressure decreases 1 psi (7 kPa). Because tire pressures fluctuate with temperature changes, tire pressures must be set when tires are at outdoor ambient temperatures. If the tire pressure may drop enough to be detected by the TPM system, which will activate the low pressure warning light.

When the tire pressure warning light comes on solid and message center displays "LOW TIRE PRESSURE", check the air pressure of all tires and adjust to the specified cold pressure listed on vehicle certification label (found on driver's door or door pillar). Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. If the vehicle has been stationary for more than 30 minutes, the sensor will enter into a "sleep mode" and stop transmitting. A TPM sensor Activation procedure may be needed. Make sure the warning light goes off. If the warning light stays on, there is a malfunction in the TPM system. See appropriate manufacturer service information.

When the tire pressure warning light flashes for 70 seconds and then remains illuminated, after bulb-check has been performed and message center displays warning messages, there is a malfunction in the TPM system. See appropriate manufacturer service information.
