• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size spare
tire does not have a tire pressure monitoring sensor.
Therefore, the TPMS will not monitor the pressure in the
spare tire.
2. If you install the compact or non-matching full size
spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, a chime will sound and
the "TPMS Telltale Light" and "LOW TIRE PRESSURE"
and Inflate to XX messages will turn on upon the next
ignition cycle.
3. After driving the vehicle for up to 20 minutes above
15.5 mph (25 km/h), the "TPMS Telltale Light" will flash
on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition cycle, a chime will sound
and the "TPMS Telltale Light" will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare or
non-matching full size spare, the TPMS will update
automatically and the "TPMS Telltale Light" will turn
off, as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15.5 mph (25 km/h) in order for the TPMS to
receive this information.
Tire Pressure Monitor System Operation
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
