SAFETY 167
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 TPMS 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 TPMS 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 TPMS 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 TPMS 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 TPMS 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 TPMS 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 TPMS 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.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such as when
installing winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
TPMS sensors. Then, drive the vehicle for 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
remain on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then display
dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
