158 SAFETY
Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring Warning Light” will flash on and off for
75 seconds and then remain on solid. In addition,
the instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds
and then display dashes (- -) in place of the
pressure value to indicate which sensor is not
being received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the “Tire Pressure
Monitoring Warning 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:
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the TPM sensors.
Installing aftermarket window tinting that
contains materials that may block radio wave
signals.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPM sensors.
A system fault may occur due to an incorrect TPM
sensor location condition. When a system fault
occurs due to an incorrect TPM sensor location,
the “Tire Pressure Monitoring Warning Light” will
flash on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime.
In addition, the instrument cluster will display a
“Tire Pressure Temporarily Unavailable” message
in place of the tire pressure display screen. If the
ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system
fault no longer exists, the “Tire Pressure
Monitoring Warning Light” will no longer flash and
the tire pressure display screen will be displayed
showing the tire pressure values the correct
locations.
Vehicles With Non-Matching Full Size Spare Or
Compact Spare
The non-matching full size spare or compact
spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the non-matching full size spare
or compact spare tire.
If you install the non-matching full size spare or
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, the
TPM Warning Light and a “LOW TIRE” message
will remain on and a chime will sound.
In addition, the graphic in the instrument cluster
will still display a pressure value in a different
color and an “Inflate to XX” message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPM Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instrument
cluster will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (- -) in place of the pressure
value.
For each subsequent ignition switch cycle, a
chime will sound, the TPM 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 a
minimum of five seconds and then display
dashes (- -) in place of the pressure value.
Once you repair or replace the original road tire
and reinstall it on the vehicle in place of the non-
matching full size spare or compact spare, the
TPMS will update automatically. In addition, the
TPM Warning Light will turn off and the graphic
in the instrument cluster will display a new pres-
sure 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.
