276 SAFETY
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
System (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.
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 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.
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 customer
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 vehicle's front and rear
axle tires to, and to provide feedback 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 ignition 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
