268 STARTING AND OPERATING
3. Excessive accumulation of snow or ice around the
wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS Sensors.
NOTE:
1. 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.
2. 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 key cycle, a chime will
sound and the TPMS Telltale Light will turn ON due to
the low tire.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the TPMS Telltale Light will flash on
and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPMS Telltale Light will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPMS
Telltale Light will turn OFF, as long 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 (25 km/h) in order for the
TPMS to receive this information.
