GM Service Manual Online
For 1990-2009 cars only

Adjust the outside mirrors to see the side of the vehicle and have a clear view of objects behind you.

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.

Using hood-mounted air deflectors and add-on convex mirror attachments could decrease mirror performance.
