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
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 (TPM) sensor may be
in an inoperative position, preventing the TPM
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
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 assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
"SERVICE TIRE PRESSURE SYSTEM" message
and then display dashes (--) in place of the
pressure values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the "SERVICE
TIRE PRESSURE SYSTEM" message in the
instrument cluster but dashes (--) will remain in
place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPMS sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the "SERVICE TIRE
PRESSURE SYSTEM" message and then display
pressure values in place of the dashes. On the
next ignition cycle the "SERVICE TIRE
PRESSURE SYSTEM" message will no longer be
displayed as long as no system fault exists.
