282 SAFETY
If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists.
If the system fault no longer exists, the Tire
Pressure Monitoring Telltale Light will no longer
flash, and the “SERVICE TPM SYSTEM” message
will no longer display, and a pressure value will
display in place of the dashes. A system fault can
occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Lots 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 or Non-Matching
Full Size 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 TPM 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.
