4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or non-Matching Full
Size Spare
1. The compact spare tire or non-matching full size spare
tire does not have a tire pressure monitoring sensor.
Therefore, the TPMS will not monitor the pressure in
the 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, a chime will
sound and the “TPMS Telltale Light” and “LOW TIRE
PRESSURE” and ЉInflate to XXЉ messages will turn on
upon the next ignition cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition 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
or non-matching full size spare, the TPMS will update
automatically and the “TPMS Telltale 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. 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.
