176 SAFETY
• Accumulation of excessive snow and/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
• The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
• 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 switch cycle, a chime will
sound, a "LOW TIRE PRESSURE" message will be
displayed and the TPMS Warning Light will turn on.
• After driving 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.
• For each subsequent ignition switch cycle, a chime will
sound, the TPMS Warning Light will flash on and off for
75 seconds and then remain on solid.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will automatically update, and the TPMS
Warning Light will turn off as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires.
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 TPMS Warning Light will flash on and off
for 75 seconds and then remain on.
Beginning with the next ignition cycle, the TPMS will no
longer chime or flash the TPMS Warning Light.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
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.
