SAFETY 137
The system will automatically update, the
graphic display of the pressure value(s) will
return to its original color and the TPMS
Warning Light will extinguish once the updated
tire pressure(s) have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
Service TPM System Warning
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds, and
remain on solid when a system fault is detected.
The system fault will also sound a chime. The
instrument cluster display will display a
“SERVICE TPM SYSTEM” message for a
minimum of five seconds. This message is then
followed by a graphic display, with “--“ in place
of the pressure value(s), indicating which Tire
Pressure Monitoring sensor(s) 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 System Warning Light will
no longer flash, the "SERVICE TPM SYSTEM"
message will not be present, and a pressure
value will be displayed instead of dashes. A
system fault can occur by any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same Radio
Frequencies as the TPM sensors.
Lots of snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM
sensors.
NOTE:
There is no Tire Pressure Monitoring sensor in
the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the 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 Tire Pressure
Monitoring System Warning Light will remain
on, a chime will sound, and the instrument
cluster display will still display a pressure value
in the different color graphic display and an
“Inflate to XX” message will be displayed. After
driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Moni-
toring System Warning Light will flash on and off
for 75 seconds and then remain on solid. In
addition, the instrument cluster display will
display a “SERVICE TPM SYSTEM" message for
five seconds and then display dashes (--) in
place of the pressure value. For each subse-
quent ignition switch cycle, a chime will sound,
the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
then remain on solid, and the instrument
cluster display will display a "SERVICE TPM
SYSTEM" message for 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 spare tire, the TPMS will update automat-
ically.
In addition, the Tire Pressure Monitoring System
Warning Light will turn off and the graphic in the
instrument cluster display 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.
