Power Remote Control Mirror
(If Equipped)
This selector controls both
outside rearview mirrors.
Select the mirror you want to adjust by moving the switch
to the right or the left. Press any of the four arrow buttons
to move the mirror in the direction desired. Adjust each
mirror so that you can see the side of your vehicle when
you are sitting in a comfortable driving position.
Convex Outside Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved so you can see more from the
driver’s seat.
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.
