1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
2. Installing some form of aftermarket win-
dow 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
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” message will
turn on upon the next ignition cycle.
3. After driving the vehicle for up to 20 min-
utes above 15 mph (24 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 Tell-
tale Light” will turn off, as long as no tire
pressure is below the low-pressure warn-
ing limit in any of the four active road
tires. The vehicle may need to be driven
for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.
Premium System — If Equipped
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.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System
messages, which will display in the instru-
ment cluster display.
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Moni-
toring Telltale Light” will
illuminate in the instru-
ment cluster and a chime
will sound when tire pres-
