To turn the mirror on, push the ON/OFF switch, located on the bottom of the mirror, to latch it in the ON position. The switch will illuminate and the mirror will be in the automatic dimming mode. To turn the switch illumination and automatic dimming feature off, push the ON/OFF switch again. 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. There are two light sensors (photocells) in this mirror. The sensor that detects rear glare is located inside a window in the center of the mirror. The second light sensor which determines outside light level is located on the backside of the mirror case. One important safety feature is that the mirror automatically returns to the normal position whenever the vehicle is placed in R (Reverse) (when the mirror is in the ON position). This feature ensures a bright clear view in the mirror when backing up. Adjusting the Dual Electric Remote Control Mirrors Your vehicle is equipped with electric remote control side view mirrors; the switch for controlling their operation is a control knob in the armrest. Do not clean the housing or glass of any mirror with harsh abrasives, fuel or other petroleum-based cleaning products. 141
