Vehicles With a Full-Size Matching Spare
1. If your vehicle is equipped with a matching
full-size spare wheel and tire assembly, it
has a Tire Pressure Monitoring System
sensor, 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 warning
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 Monitoring
System (TPMS) 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 display the
"SERVICE TIRE PRESSURE 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
TIRE PRESSURE 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 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 display
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.
TIRE FILL ALERT
This feature notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
The customer may choose to disable or enable
the Tire Fill Alert feature in the apps menu of the
Uconnect system.
