SAFETY 319

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 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, an “Inflate to XX”
message to appear in the instrument
cluster, 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 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 transmission in PARK for
vehicles equipped with an automatic
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 (TPMS) sensor
may be in an inoperative position, preventing
the TPMS sensor signal from being received. In
this case, the vehicle may need to be moved
slightly forward or backward.
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
recommended 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.
