yellowblue Mirrors Electrochromic Day/Night Rearview Mirror with Compass When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing. Mirror Operation Your vehicle has an electrochromic inside rearview mirror with a compass. When set in the MIRROR position, this mirror automatically changes to reduce glare from headlamps behind you. The mirror also includes an eight-point compass display in the upper right corner of the mirror face. When on, the compass automatically calibrates as the vehicle is driven. The right side of the button, located at the bottom of the mirror, turns the electrochromic mirror on and off. To turn on the automatic dimming feature, press MIRROR. To turn off automatic dimming, press MIRROR again. The green indicator light will be illuminated when this feature is active. 2-49
