Electrochromic Day/Night Inside Rearview Mirror with Map Lamps (Option) Your vehicle may have an automatic electrochromic day/night rearview mirror with map lamps. This mirror automatically changes to reduce glare from headlamps behind you. A time delay feature prevents rapid changing from the day to night positions while driving under lights and through traffic. The automatic dimming feature is turned on or off by pressing the IO button located on the lower part of the mirror. Press and hold the IO button for up to three seconds to turn this feature on or off. When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror housing. Driver's Outside Auto-Dimming Rearview Mirror (If Equipped) The driver's side outside mirror will adjust for the glare of headlamps behind you. This feature is controlled by the on and off setting on the inside electrochromic mirror. See "Electrochromic Day/Night Rearview Mirror" in the Index. The mirror includes two map lamps and an automatic dimming function. 2-55
