REAR : If equipped, press to turn the

outside mirrors, they turn on when the rear
window defogger button is on and help to
clear fog or frost from the surface of the
mirror. See Heated Mirrors 0 26.

clear the inside rear window can damage
the rear window defogger. Repairs would
not be covered by the vehicle warranty.
Do not clear the inside rear window with
sharp objects.
