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 sensor may be in an inoperative position, pre-
venting 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 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 (STFA) —
IF EQUIPPED
The 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 vehi-
cle's tires.
NOTE:
To use the STFA feature, the Tire Fill Alert feature must
be enabled through use of the customer settings in the
radio.
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.
You may also store pressure values chosen for each
axle in the Uconnect system application as preset pres-
sure values. Up to two sets of preset pressure values
can be stored in the Uconnect system for the front and
rear axle. Once you select the tire pressures for the
front and rear axles that you want to inflate or deflate
to, you can begin inflating or deflating one tire at a
time.
SAFETY
NOTE:
The STFA system will only support inflating or deflating
one tire at a time.
The system will be activated when the TPMS receiver
module detects a change in tire pressure. The ignition
must be in the ON/RUN mode, with the transmission in
PARK in vehicles with an automatic transmission, and
in NEUTRAL with the parking brake engaged in vehicles
with a manual transmission. The hazard lamps will
come on to confirm the vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire pressure
screen will be displayed in the instrument cluster. If the
hazard lamps do not come on while inflating or deflat-
ing the tire, the Tire Pressure Monitoring System 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.
Horn chirps will indicate STFA status as tires are
inflated/deflated. The horn will chirp under the follow-
ing STFA states:
1. The horn will chirp once when the selected pressure
is reached to let you know when to stop inflating or
deflating the tire.
2. The horn will chirp three times if the tire is overin-
flated or over-deflated.
3. The horn will chirp once again when enough air is
added or removed to reach proper selected pres-
sure level.
