Outside Power Mirrors
The outside power mirror
controls are located near
the driver's side window,
on the armrest.
Use the selector switch located above the four-way
control panel to choose either the left or right outside
mirror. Then press any of the four arrows located on the
control pad to move each mirror in the desired
direction.
Adjust each mirror so you can see the side of your
vehicle and the area beside and behind your vehicle.
Heated Outside Mirrors
If your vehicle has this feature, the surface of both
outside mirrors will heat when you activate the
rear window defogger.
Outside Convex 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.
A convex mirror can make tt gs (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.
