SAFETY 199
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 or
non-matching full size 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.
To reactivate the TPMS, replace all four wheel and
tire assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
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 turn off. The
instrument cluster will display the “Service Tire
Pressure System” message and then display
pressure values in place of the dashes. On the next
ignition cycle the "Service Tire Pressure System"
message will no longer be displayed as long as no
system fault exists.
