This feature notifies the user when the placard tire pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill Alert feature through use of the customer settings in the radio.
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 TPMS fault is set to “active” or if the system is in deactivation mode (if equipped).
The system will be activated when the system detects an increase of tire pressure, while filling the fire. The ignition must be in the RUN mode, with the transmission in PARK (P).
It is not required to have the engine running to enter Tire Fill Alert mode.
The Hazard Warning Flashers will come on to confirm the vehicle is in Tire Fill Alert mode.
If the Hazard Warning Flashers do not come on while inflating the tire, the TPMS 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.
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 overfilled 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 underinflated and will continue to chirp every five seconds if the user continues to deflate the tire.
After use, the TFA feature will NOT remain active after ignition shut down. The feature will need to be re-enabled when the vehicle is restarted UCONNECT SETTINGS.
