● Installing some form of aftermarket window tinting
that aff
ects radio wave signals.
● Lots of snow or ice around the wheels or wheel
housings.
● 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.
3. 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 will display a “SERVICE
TPM S
YSTEM” 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, 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 10
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 10 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.
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 10 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 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.
