SAFETY
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a differ-
ent color in the instrument cluster graphic) to the vehi-
cle's recommended cold placard pressure value as
shown in the "Inflate to XX" message. Once the system
receives the updated tire pressures, the system will
automatically update, the pressure values in the
graphic display in the instrument cluster will return to
their original color, and the TPMS Warning Light will
turn off.
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 TPMS 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 TPMS 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 TIRE PRESSURE SYSTEM" message for a mini-
mum of five seconds and then display dashes (--) in
place of the pressure value to indicate which sensor is
not being received.
If the ignition is cycled, this sequence will repeat, pro-
viding the system fault still exists. If the system fault no
longer exists, the TPMS Warning Light will no longer
flash, and the "SERVICE TIRE PRESSURE SYSTEM" mes-
sage 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
housings
•
Using tire chains on the vehicle
•
Using wheels/tires not equipped with TPMS sensors
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 Pres-
sure Monitoring System sensor, and can be moni-
tored 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 igni-
tion 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 cluster, and
the graphic display will still show the low tire pres-
sure 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 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 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 display the "SERVICE TIRE PRES-
SURE 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 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
display pressure values in place of the dashes. On the
next ignition cycle the "SERVICE TIRE PRESSURE SYS-
TEM" 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 customer settings menu of the
Uconnect system.
NOTE:
•
Only one tire can be filled at a time when using the
Tire Fill Alert system.
•
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to "active" or if the system
is in deactivation mode (if equipped).
