SAFETY139
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 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
over filled 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 under-inflated and will continue to
chirp every five seconds if the user continues
to deflate the tire. 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 the customer to select a pres
-
sure to inflate or deflate the vehicle's front and
rear axle tires to and to provide feedback to the
customer while inflating or deflating the
vehicle's tires.
In the Selectable Tire Fill Alert customer
settings menu in the radio, the customer 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.
The customer may also store the pressure
values chosen for each axle in the radio as a
preset pressure. The customer will be allowed
to store up to two sets of preset values in the
radio for the front and rear axle pressure values.
Once the customer selects the tire pressures for
the front and rear axles that they want to inflate
or deflate to, they 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 detects a change in tire pres
-
sure. The ignition must be in the RUN mode,
with the transmission in PARK (P).
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 display screen will be displayed in the
instrument cluster.
Operation:
The horn will chirp once when the selected
pressure is reached to let the user know
when to stop inflating or deflating the tire.
The horn will chirp three times if the tire is
over inflated or over deflated and will
continue to chirp every five seconds if the
user continues to inflate or deflate the tire.
The horn will chirp once again when enough
air is added or removed to reach proper
selected pressure level.
