yellowblue One photocell on the front of the mirror senses when it is becoming dark outside. Another photocell, facing rearward, senses headlamps behind you. To turn the electrochromic feature off, press the button on the bottom of the mirror again. To keep the photocells operating well, occasionally clean them with a cotton swab and glass cleaner. Convex Outside 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. CAUTION: 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. Power Outside Mirrors The power mirror control is near the driver's window, on the armrest. Turn the control counterclockwise to adjust the left mirror or clockwise to adjust the right mirror. Then move the control in the direction you want to move the mirror. 2-58
