Selectable Tire Fill Alert (STFA) —
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 ≥15 psi to XX 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 pressure 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.
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 deflating 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
following 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
overinflated or over-deflated.
3. The horn will chirp once again when enough
air is added or removed to reach proper
selected pressure level.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
