They (flippers) are invaluable if you drive in mountains frequently. I had them in my Santa Fe 2.0T and quickly learned how to use and love them. So in my Palisade they were a part of the buying decision. They are most useful when traffic is continually changing speed in a downhill situation. Usually you need to change more than one gear up or down because there is a wide range between first and eighth gear. To disengage simply hold the + flipper in for a couple of seconds. The gear being used is displayed on the display. As mentioned before, they are also handy after leaving the freeway to slow down on the off ramp or approaching a traffic light. Stay safe.
