Outside Power Foldaway Mirrors The power mirror controls are located on the driver's door armrest. 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 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. To choose either the left or right outside mirror, move the selector switch located above the control pad to the left or the right. Then use the four-way arrows located on the control pad to move the mirrors in the desired direction. Adjust each mirror so you can see the side of your vehicle and the area behind your vehicle. 2-33
