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
Tire Pressure Monitoring System Warning Light off.
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.
Service TPMS Warning
When a system fault is detected, the Tire Pressure
Monitoring System Warning Light will flash on and off for
75 seconds and then remain on solid. The system fault will
also sound a chime. In addition, the instrument cluster will
display a "SERVICE TPM SYSTEM" message for a minimum
of five seconds and then display dashes (--) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition key 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, and the "SERVICE TPM
SYSTEM" message will no longer display, and a pressure
value will display in place of the dashes. A system fault can
occur due to any of the following:
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors
Installing some form of aftermarket window tinting that
affects radio wave signals
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
Vehicles With Compact Spare Or Non-Matching Full Size
Spare
1.
The compact spare tire or non-matching full size
does not have a Tire Pressure Monitoring System
sensor. Therefore, the TPMS will not monitor the
pressure in the compact or non-matching full size
spare tire.
2.
If you install the compact or non-matching full size
spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, the Tire Pressure Monitoring
System Warning Light will remain on and a chime will
sound. In addition, the graphic in the instrument
cluster will still display a different color or highlighted
pressure value and the "Inflate to XX" message.
3.
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 will display a "SERVICE TPM
SYSTEM" message for five seconds and then display
dashes (--) in place of the pressure value.
4.
For each subsequent ignition key 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 will
display a "SERVICE TPM SYSTEM" message for
five seconds and then display dashes (--) in place of
the pressure value.
5.
Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact
spare or non-matching full size, the TPMS will update
automatically. In addition, the Tire Pressure
Monitoring System Warning Light will turn off and the
graphic in the instrument cluster 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
Tire Pressure Monitoring System (TPMS) sensors. Then,
drive the vehicle for 20 minutes above 15 mph (24 km/h).
The TPMS will chime, the Tire Pressure Monitoring System
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.
