Electronic Day/Night Mirror (AEROSTAR)
The electronic day/night mirror changes from the normal state to the non-glare state when glare reaches the mirror. This mirror mainly functions at night, with 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 glare goes away, and prevents excessive changing of the mirror as traffic moves behind and around the vehicle, or on rolling hills and curves. The sensitivity of the mirror can be adjusted by moving the switch between LOW and HIGH. See Fig 1 .
HIGH is the most sensitive setting and bright headlamps far away will cause the mirror to automatically darken. At the LOW setting, bright headlamps will have to be closer to darken the mirror. The electronic mirror also measures the brightness of the light in front of the vehicle. It automatically makes a correction in the glare state selected on the switch. The mirror automatic function may be turned off by sliding the switch to the OFF position. It may be turned off in either the normal or non-glare state.
There are two light sensors (photocells) in this mirror. The sensor that detects rear glare is located inside a window in the upper right 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 locks in the normal state whenever the vehicle is placed in REVERSE. This feature makes sure the view in the mirror is clear and bright when backing up.
