SAFETY 223
SERVICE TPMS WARNING
If a system fault is detected, the TPMS 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 "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.
Tire Pressure Monitoring System Display
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the TPMS 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 TPMS 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 TPMS
sensors
A system fault may occur due to an incorrect TPMS
sensor location condition. When a system fault
occurs due to an incorrect TPMS sensor location,
the TPMS 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 TPMS Warning Light will no
longer flash and the tire pressure display screen
will be displayed showing the tire pressure values
for 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 TPMS sensor. There-
fore, 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
TPMS Warning Light and a “LOW TIRE” message
will remain on and a chime will sound. In addi-
tion, 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 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 TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pressure
value.
