1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots 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:
If your vehicle is equipped with a matching full
size spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that the
matching full size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, and a chime to sound. Driving the vehicle for up to
10 minutes above 15 mph (25 km/h) will turn OFF the
“Tire Pressure Monitoring Telltale Light” as long as none
of the road tires are below the low pressure warning
threshold.
NOTE:
If your vehicle is not equipped with a matching
full size spare wheel and tire assembly, it does not have a
tire pressure monitoring sensor in the spare tire. The
TPMS will not be able to monitor the tire pressure. If you
install the spare tire in place of a road tire that has a
pressure below the low-pressure warning limit, upon the
next ignition key cycle, a chime will sound and the “Tire
Pressure Monitoring Telltale Light” will turn ON. After
driving the vehicle for up to 10 minutes above 15 mph (25
km/h), the “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
For each subsequent ignition key cycle, a chime will
sound and the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid. Once you repair or replace the original road tire,
