Optional
If your Buick has the
optional power mirror, the
mirror control is located on
the driver's door.
Move the switch in the middle of the control to choose
the right or left mirror. Push the arrow controls in the
direction you want to move the mirror.
Adjust each mirror so you can just see the side of your
vehicle and the area behind your vehicle.
Convex Outside Mirror
Your right side mirror is convex.
A convex mirror's surface is curved so you can see more
from the driver's seat.
Heated Outside Rearview Mirror
(Option)
If you have
this
option, the left outside mirror is heated
when you activate the rear window defogger.
