2008 GMC Savana Van Owner's Manual - Page 113

Outside Power Mirrors If the vehicle has power mirrors, the control is located on the driver's side door. Outside Convex Mirror {CAUTION: A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on your right. Check your inside mirror or glance over your shoulder before changing lanes. Select each mirror by turning the knob clockwise for the passenger's side mirror or counterclockwise for the driver's side mirror. The center position is neutral. Then, adjust the mirror angle by moving the knob in the desired direction. The auxiliary convex mirrors can only be adjusted manually. The passenger side mirror may have convex glass. A convex mirror's surface is curved so more can be seen from the driver's seat. It also makes things like other vehicles, look farther away than they really are. 2-33
