Tire Pressure Monitoring Low Pressure Warnings
The TPM Light will illuminate in the instrument
cluster and a chime will sound when tire pressure
is low in one or more of the four active road tires.
Should this occur, you should stop as soon as possible,
check the inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update and the TPM Light will turn off. The vehicle may
need to be driven for up to 10 minutes above 15 mph (25
km/h) in order for the TPMS to receive this information.
Check TPMS Warning
The TPM Light will flash on and off for 75 seconds and
then remain on solid when a system fault is detected. The
system fault will also sound a chime. If the ignition key is
cycled, this sequence will repeat, providing the system
fault still exists. The TPM Light will turn off when the
fault condition no longer exists. A system fault can occur
due to any of the following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same Radio Frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials which may block radio wave signals.
3. Excessive accumulation of snow or ice around the
wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
1. The compact spare tire (if so equipped) does not have
a tire pressure monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare tire.
