low-pressure warning limit, upon the next
ignition cycle, the TPMS Warning Light
will remain on and a chime will sound. In
addition, the graphic in the instrument
cluster will still display a different color
pressure value.
3. After driving the vehicle for up to 10 min-
utes 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 will
display a "Service Tire Pressure System"
message for five seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition cycle, a
chime will sound, the TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment cluster will display a "SERVICE
TIRE PRESSURE 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 TPMS
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.
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, and the graphic
display will still show the low tire pressure
value in a different color.
3. Driving the vehicle for up to 10 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 10 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.
