Four Tire Pressure Monitoring Sensors
•
Tire Pressure Monitoring Telltale Light
The matching full size spare wheel and tire as-
sembly (if equipped) has a tire pressure monitor-
ing sensor. The matching full size spare can be
used in place of any of the four road tires. The
TPMS will only monitor the pressure in the full size
spare when it is used in place of a road tire.
Otherwise, a spare with a pressure below the
low-pressure limit will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime
to sound.
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale 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 pres-
sure value. Once the system receives the updated
tire pressures, the system will automatically up-
date and the Tire Pressure Monitoring Telltale
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 infor-
mation.
Check TPMS Warning
When a system fault is detected, the Tire Pressure
Monitoring Telltale Light will flash on and off for 75
seconds and then remain on solid. 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 Tire Pressure Monitor-
ing Telltale Light will turn off when the fault condi-
tion no longer exists. A system fault can occur due
to any of the following:
1. Jamming due to electronic devices or driving
next to facilities emitting the same radio frequen-
cies 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 sen-
sors.
NOTE:
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire
assembly has a tire pressure monitoring sensor
that can be monitored by the TPMS.
2. If you install the full size spare 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 TPM Telltale
Light will turn ON.
3. 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 no tire pres-
sure is below the low-pressure warning limit in any
of the four active road tires.
NOTE:
Vehicles with Compact Spare
1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare
tire.
2. If you install the compact 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.
3. After driving the vehicle for up to 10 minutes
above 15 mph (25 km/h), the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75
seconds and then remain on solid.
4. 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.
5. Once you repair or replace the original road
tire, and reinstall it on the vehicle in place of the
compact spare, the TPMS will update automati-
