Mirrors Automatic Dimming Inside Rearview Mirror (If equipped) The electronic day/night mirror will change from the normal state to the non-glare state when bright lights (glare) reach the mirror. This mirror functions at night, and has a limited function at dusk or dawn. From the non-glare state, the mirror will return to the normal state after a short delay. The delay starts when the glare goes away. The delay prevents excessive changing of the mirror as traffic moves behind and around the vehicle, or on rolling hills and curves. The automatic non-glare mirror To turn the mirror on or off, push the On/Off switch, located on the bottom of the mirror. The switch will illuminate in the on position. The electronic mirror measures the brightness of the light coming in from the rear of the vehicle. It automatically makes a correction in the glare state. The mirror may be turned off in either the normal or non-glare position. 89
