WARNING
Incorrectly estimating distances with the right outside mirror can cause collisions and seri-
ous injury.
The right outside mirror has a convex (curved) surface. This widens your field of vision.
But vehicles or other objects seen in a convex mirror will look smaller and farther away than
they really are.
If you use the right outside mirror to judge distances from vehicles behind you when
changing lanes, you could estimate incorrectly and cause a crash and serious injuries.
Whenever possible, use the inside mirror to more accurately judge distance and size of
vehicles or other objects seen in the convex mirror.
Always make sure you have a clear view to the rear of the vehicle.
NOTICE
Always fold in the outside mirrors when taking the vehicle through an automatic car wash.
Never fold power mirrors in manually because doing so could damage the electrical drive.
To reduce fuel consumption, use outside mirror heating only when needed.
When first switched on, outside mirror heating works with maximum heat for about 2 minutes.
If power mirror adjustment does not work, the outside mirrors can be adjusted by hand by press-
ing on the edges of the mirror surface.
