The automatic day-night mirror system consists of an inside rearview mirror.

With the ignition switch in the ON position, ignition 3 voltage is supplied through the A/C CRUISE fuse to the inside rearview mirror. The inside rearview mirror uses 2 photocell sensors in order to determine light conditions in the front and the back of the vehicle. At night, with the automatic day-night feature enabled, the mirror automatically darkens to reduce the glare from the headlamps from behind. In the daytime, the mirror is in a normal state. With the gear selector lever in the REVERSE position, backup lamp supply voltage is supplied as an input to the inside rearview mirror. The inside rearview mirror will gradually change to a normal state as a result of the backup lamp supply voltage input. Ground for the inside rearview mirror is provided by G302.
