242 SAFETY
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster, and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. In addition,
the instrument cluster will display an "Inflate to XX"
message and a graphic display of the pressure value(s)
with the low tire(s) in a different color
Ú page 96.
NOTE:
Your system can be set to display pressure units in PSI,
BAR, or kPa.
Low Tire Pressure Monitoring System Display
Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and
inflate the low tire(s) that is in a different color on the
graphic display to the vehicle’s recommended cold tire
pressure displayed in the “Inflate to XX” message.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
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 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:
There is no Tire Pressure Monitoring System 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 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 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 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
