The outside power mirror control is located on the driver door.
If you reach the mirror's end of the travel position in any direction, the mirror enters a ratcheting mode. This action is harmless. It is a warning that the mirror can go no further. To stop this action, back the mirror up by moving the control in the opposite direction.
Manually fold the mirrors inward to prevent damage when going through an automatic car wash. To fold, push the mirror toward the vehicle. Push the mirror outward, to return to its original position.
