226 SAFETY
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 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 TPM receiver module
dete
cts 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 transmis
-
sion. The hazard lamps will come on to confirm the vehicle
is i
n Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire pressure screen
will
be displayed in the instrument cluster.
Horn chirps will indicate STFA status as tires are inflated/
defl
ated. The horn will chirp under the following STFA
states:
1. The horn will chirp once when the selected pressure is
rea
ched to let you know when to stop inflating or
deflating the tire.
2. The horn will chirp three times if the tire is over-inflated
or
over-deflated.
3. The horn will chirp once again when enough air is added
or
removed to reach proper selected pressure level.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel and
tire
assemblies (road tires) with wheel and tire assemblies
that do not have TPMS sensors, such as when installing
winter wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel and tire
asse
mblies (road tires) with tires not equipped with Tire Pres-
