Lots of folks don't know this one:
In reverse, the mirrors tilt down if the mirror adjuster switch is in the right, or left position. If it is in the center position, they will NOT tilt down. As long as you have around view monitor, you probably don't want/need them to tilt down.
Speaking of cameras: Most folks know you can press the "Camera" button on the dash while parking to turn on the forward facing camera. You can also press that button again, to switch the alternate (top down view is standard) to side view, or a second time to make it a very wide angle view out the front - this is useful if pulling out of a parking garage right onto a sidewalk with pedestrians. The "Change View" button on the screen also accomplishes the same thing.
