Features 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 upper RH corner 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. To turn on the automatic mirror, have the key in the ON position and push the ON button once. The light in the center of the button will light indicating the mirror is on. To turn the mirror off push the ON button again. The mirror can be temporarily darkened, if wanted, by pushing the Dim button. After releasing the button, the mirror will return to the previous operation mode after a short delay. 189
