• 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 switch cycle, the “Tire Pressure Monitoring
Telltale Light” will remain ON, a chime will sound, and
the instrument cluster will still display a highlighted or
different color pressure value in the graphic display.
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring Tell-
tale Light” will flash on and off for 75 seconds and then
remain on solid. In addition, the instrument cluster will
display a “SERVICE TPM SYSTEM
⬙
message for a
minimum of five seconds and then display dashes (- -) in
place of the pressure value. For each subsequent ignition
switch cycle, a chime will sound, the “Tire Pressure
Monitoring 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 a minimum of five seconds and then display dashes
(- -) in place of the pressure value.
• Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the “Tire Pressure Monitoring 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 assem-
blies 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.
