The customer may choose to disable or enable the Tire Fill
Alert feature through use of the customer settings in the
radio.
NOTE:
• Only one tire can be filled at a time when using the Tire
Fill Alert system.
• The Tire Fill Alert feature cannot be entered if an existing
TPM system fault is set to “active” or if the system is in
deactivation mode (if equipped).
The system will be activated when there is over 1.5 psi (10
kPa) of change in tire pressure. The ignition must be in the
RUN mode, with the transmission in PARK (P).
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.
When Tire Fill Alert Mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
•
The horn will chirp 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.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies 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 ve-
hicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the ⬙ TPM Telltale Light ⬙ will flash on and off for
75 seconds and then remain on. The instrument cluster will
display the “SERVICE TPM SYSTEM” message and then
display dashes (--) in place of the pressure values.
