Automatic Headlamp Dimmer
The Headlamp Dimmer Sensor senses the headlights of oncoming cars and activates the HI-LO Beam Relay. The relay switches the headlamps to lo beams. When oncoming headlight are no longer sensed, the relay switches the headlamps back to hi beams.
Sensitivity of the Headlamp Dimmer Sensor is adjusted by the Auto Dimmer Control located on the instrument panel. Turning the control clockwise increases the Headlamp Dimmer Sensor's sensitivity (lamps will dim at greater distance).
When the Multi-function Switch Dimmer Switch is in the LO position and the turn signal lever is pulled partway toward the driver, the hi beams will flash.
