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.
SERVICE 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. In
addition, the instrument cluster will display a
"SERVICE TPM SYSTEM" message for a mini-
mum of five seconds and then display dashes
(- -) in place of the pressure value to indicate
which sensor is not being received.
If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the “Tire
Pressure Monitoring Telltale Light” will no longer
flash, and the “SERVICE TPM SYSTEM” mes-
sage will no longer display, and a pressure value
will display in place of the dashes. A system fault
can occur due to any of the following:
• Jamming due to electronic devices or driving
next to facilities emitting the same radio fre-
quencies 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 housings.
• 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 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 or non-matching full
size spare tire in place of a road tire that has
a pressure below the low-pressure warning
limit, upon the next ignition key cycle, the
“TPMS Telltale Light” will remain on and a
chime will sound. In addition, the graphic in
the instrument cluster will still display a dif-
ferent color or highlighted pressure value
and the “Inflate to XX” message.
3. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the “TPMS Telltale
Light” will flash on and off for 75 seconds and
then remain on solid. In addition, the instru-
ment cluster will display a “SERVICE TPM
SYSTEM” message for five seconds and
then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a
chime will sound, the “TPMS Telltale Light”
will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a “SERVICE TPM SYSTEM”
message for five seconds and then display
dashes (- -) in place of the pressure value.
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,
the TPMS will update automatically. In addi-
tion, the “TPMS Telltale Light” will turn off and
the graphic in the instrument cluster will
display a new pressure value instead of
dashes (- -), 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 mph (24 km/h) in order for the TPMS to
receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale Light" will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display
dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE
