Your vehicle may have outside heated mirrors which help clear them of condensation, snow, and ice. When the rear window defogger button is pressed, the heated mirrors are also turned on. Only the upper glass of the mirror is heated. The lower convex part of the mirror is not heated. Your mirror may also have a turn signal arrow that will flash in the direction of the turn or lane change. To adjust each mirror, press one of the four arrows located on the control pad to move the mirror in the direction you want it to go. Adjust each outside mirror so that you can see a little of your vehicle, and the area behind your vehicle. The mirrors may also include a memory function that works with the memory seats. See Memory Seat, Mirrors, and Pedals on page 13 for more information. The mirrors can be manually folded inward to prevent damage when going through an automatic car wash. To fold, push the mirror toward the vehicle. To return the mirror to its original position, push outward. Be sure to return both mirrors to their original unfolded position before driving. Outside Power Mirrors If your vehicle is equipped with outside power mirrors, the controls are located on the driver's door armrest. Press (A) to select the driver's side mirror or (B) to select the passenger's side mirror. 164
