240 SAFETY
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 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 Tire Pressure Monitoring System (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
Tire Pressure Monitoring System 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”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 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
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
"SERVICE TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.
