PRINCIPLES OF OPERATION

Exterior Rear View Mirrors
The rear view mirror system consists of 2 exterior mirrors (each mirror includes 2 mirror motors) mounted on the exterior doors, an exterior mirror control switch and an interior rear view mirror.

The exterior mirrors are electrically controlled by the exterior mirror control switch for both vertical and horizontal movement. The exterior mirror control switch is hardwired to the exterior mirrors. When the LH or RH exterior mirror is selected, adjustment is carried out by moving the control to the desired position.

Auto-Dimming Interior Rear View Mirror
The interior rear view mirror may be equipped with an auto-dimming option. This feature automatically reduces the glare caused by headlamps reflecting in the mirror. The auto-dimming feature is disabled when the vehicle is in REVERSE. Power is supplied to the auto-dimming interior mirror when the ignition is in the RUN or ACC position.

The auto-dimming feature has 2 photoelectric sensors that detect forward and rear light conditions, and based on those inputs, adjusts the reflectance level of the mirror to eliminate unwanted glare. The reflectance level of the mirror glass is variable and depends on the amount of rear glare in relation to ambient light conditions in front of the interior mirror.

When the forward sensor detects daytime conditions, the rear sensor is inactive, and the mirror stays in a high reflectance mode. When the forward sensor detects nighttime conditions, the rear sensor is active and detects glare from the highlights of vehicles approaching from the rear or other glare producing light sources. To provide increased visibility when backing up, the mirror will automatically return to a high reflectance mode whenever the shifter is placed in REVERSE.

If the forward or rear sensors are blocked, the auto-dimming interior mirror might not work correctly.
