Vehicles with outside power mirrors have controls located on the driver's door.
If the travel position in any direction of the mirror is reached, it 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 knob 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. To return the mirror to its original position, push outward. Be sure to return both mirrors to their original unfolded position before driving.
