SAFETY 243
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 10 minutes above 15 mph (24 km/h) to
receive this information.
Service TPMS 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 System
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
TPMS sensors.
 Lots of snow or ice around the wheels or wheel hous -
ings.
 Using tire chains on the vehicle.

Using wheels/tires not equipped with TPMS sensors.
NOTE:
Only vehicles equipped with a full size matching spare
(i.e., matching with a road wheel) come with a Tire
Pressure Monitoring System (TPMS) sensor mounted in
the spare tire. In either option of having a full size spare
equipped or not, the tire pressure is not monitored or
displayed on the cluster for the corresponding spare tire
location. 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 Moni -
toring 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.
After driving the vehicle for up to 10 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring 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 subsequent 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
automatically.
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
10 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
