TPMS with Tire Fill Assist provides visual and audible assistance during tire pressure adjustment. With the power mode in ON and the transmission in P, while you adjust tire pressure up or down, the system alerts you as follows:

Below recommended pressure: The beeper sounds and exterior lights flash once every five seconds.

At recommended pressure: The beeper sounds and exterior lights flash rapidly for three seconds with five-second intervals. Stop filling the tire.

Above recommended pressure: The beeper sounds and lights flash twice every two seconds.

When a certain amount of time has passed since the power mode is set to ON, Tire Fill Assist will be canceled until you set the power mode to OFF.

You cannot use Tire Fill Assist if the engine was started by the remote engine start, or if there is a malfunction in the system. If Tire Fill Assist does not work, use a tire pressure gauge.
