To adjust the power mirrors: 1. Move the selector switch to the L (left) or R (right) to choose the driver or passenger mirror. 2. Press one of the four buttons located on the control pad to move the mirror to the desired direction. 3. Return the selector switch to the center position once the mirrors are adjusted. If the mirror begins making a ratcheting sound, the mirror has reached the end of its travel and can go no farther in that direction. To stop the sound, reverse the mirror direction using the control pad. Manually fold the mirrors inward to prevent damage when going through an automatic car wash. To fold, push the mirror toward the vehicle. Push outward, to return the mirror to its original position. Outside Convex Mirror { WARNING: 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 the right. Check the inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex shaped. A convex mirror's surface is curved so more can be seen from the driver seat. 3-39
