SAFETY
175
Accumulation 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
1. The compact spare tire or non-matching
full size does not have a Tire Pressure
Monitoring System 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 Warning Light will remain
on and a chime will sound. In addition, the
graphic in the instrument cluster will still
display a different color pressure value and
an "Inflate to XX" message.
3. After driving the vehicle for up to
20 minutes above 15 mph (24 km/h), the
TPMS Warning Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will display
a “Service Tire Pressure 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 Warning Light
will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a “Service Tire Pressure 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
addition, the TPMS Warning 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 Tire Pressure Monitoring System (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
System (TPMS) sensors. Then, drive the vehicle
for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“Service Tire Pressure 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 Tire
Pressure System” message in the instrument
cluster but dashes (--) will remain in place of the
pressure values.
