To adjust the outside rearview mirror, move the selector switch in the middle of the control to L for the driver's side mirror or to R for the passenger's side mirror. Then use the arrows located on the four-way control pad to move the mirror in the desired direction. To make sure you do not accidentally move a mirror, return the selector switch to the middle position (off) after adjusting the mirrors. 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 r...ror 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. 2-33
