Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells and mirror face when necessary.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Outside Manual Mirror
Adjust your outside mirrors so you can see a little of the
side of your vehicle and the area beside and behind
your vehicle from a comfortable driving position.
You can also fold the mirrors in before entering a car
wash. Pull the mirrors in toward the vehicle. Push
the mirrors back out when ®nished.
Outside Power Mirrors
If your vehicle has this
feature, the controls are
located on the driver's door
armrest.
Move the selector switch to the left or right to choose
the driver's or passenger's mirror, then use the
arrows located on the four-way control pad to move the
mirror in the direction you want the mirror to go.
Put the selector switch back in the center position when
®nished adjusting the mirror so that you don't
accidentally bump into the control pad and get the
mirror out of adjustment.
