Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a match-
ing full-size spare wheel and tire assem-
bly, it has a tire pressure monitoring sen-
sor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when
swapped with a low pressure road tire.
2. In the event that the matching full-size
spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, an Inflate to XX
message to appear in the instrument clus-
ter, and the graphic display will still show
the low tire pressure value in a different
color.
3. Driving the vehicle for up to 20 minutes
above 15 mph (24 km/h) will turn off the
TPMS Warning Light as long as none of
road tires are below the low pressure warn-
ing threshold.
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 Moni-
toring (TPM) 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 dis-
play the “SERVICE TIRE PRESSURE SYS-
TEM” 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 TIRE PRESSURE SYSTEM” mes-
sage 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 TIRE
PRESSURE SYSTEM” message and then dis-
play pressure values in place of the dashes.
On the next ignition cycle the "SERVICE TIRE
PRESSURE SYSTEM" message will no longer
be displayed as long as no system fault exists.
