Is there any way to limit the opening height on a 2015 Sienna power liftgate? My wife is short and cannot reach to reach the button to make itcome down. IIRC the salesman set it with the button on the liftgate itself, he has since left the dealership. I have been unable to do so. Neither the dealer service or Toyota customer "experience" center has provided an answer of yes and how or no I am in another planet.
