Lots of snow or ice around the wheels or wheel
housings.

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.
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.
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 system fault is set to “active” or if the
system is in deactivation mode (if equipped).
The system will be activated when the system detects
an increase in tire pressure while filling the tire. The
ignition must be in the ON/RUN mode with the trans-
mission in PARK for vehicles equipped with an auto-
matic transmission. For vehicles equipped with a
manual transmission, the parking brake must be
applied.
NOTE:
It is not required to have the engine running to enter
Tire Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is
in Tire Fill Alert mode. If the hazard lamps do not come
on while inflating the tire, the Tire Pressure Monitoring
System (TPMS) sensor may be in an inoperative posi-
tion, preventing the TPMS sensor signal from being
received. In this case, the vehicle may need to be
moved slightly forward or backward.
The Tire Fill Alert system will only inflate or deflate one
tire at a time. Wait until the hazard lights have stopped
flashing for 30 seconds after the desired pressure is
achieved in one tire before switching to another.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument
cluster.
Operation:
•
The horn will chirp once to let the user know when
to stop filling the tire, when it reaches recom-
mended pressure.
•
The horn will chirp three times if the tire is overfilled
and will continue to chirp every five seconds if the
user continues to inflate the tire.
•
The horn will chirp once again when enough air is let
out to reach proper inflation level.
•
The horn will also chirp three times if the tire is then
underinflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
NOTE:
The Tire Fill Alert feature is set to “Disabled” every time
the ignition is turned to “OFF”. To re-enable the Tire Fill
Alert feature at the next ignition “RUN” state, the cus-
tomer must re-enable the feature through use of the
customer settings in the radio.
SELECTABLE TIRE FILL ALERT — IF EQUIPPED
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the normal
Tire Fill Alert system. The system is designed to allow
you to select a pressure to inflate or deflate the vehi-
cle's front and rear axle tires to, and to provide feed-
back while inflating or deflating the vehicle's tires.
In the Selectable Tire Fill Alert application, which is
located in the apps menu of the Uconnect system, you
will be able to select a pressure setting for both the
front and rear axle tire pressures by scrolling through a
pressure range from XX to 15 psi in 1 psi increments for
each axle setting.
XX = the vehicle's cold placard pressure values for the
front and rear axles as shown on the vehicle placard
pressure label.
NOTE:
The Tire Fill Alert feature disables every time the igni-
tion is placed in the OFF position. The feature must be
re-enabled through the radio each time the ignition is
placed back in the ON/RUN position
page 181.
