Assist, you will be asked to enter your height and the camera in your vehicle will automatically detect the center of
your face to determine
the position of your head. The vehicle then uses this information to adjust the position of your seat, Active Driving

this feature unless you choose to create a Driver Profile as detailed above; if you create a Driver Profile
your ideal driving position settings will be stored with your Driver Profile. This is a convenience feature and you
can adjust vehicle settings manually instead of using the camera.
