Headlamp Switch: Description and Operation

Fig.12 Headlamp Leveling Switch Location:

HEADLAMP LEVELING SWITCH
The Headlamp Leveling Switch is located on the center instrument panel area in the accessory switch bezel, and is the primary controller of the headlamp leveling system. The leveling switch has four settings 0 - 3, 0 being the lowest, and 3 being the highest headlamp beam vertical setting.

With the rotation of the headlamp leveling switch control knob, voltage is adjusted at the headlamp leveling switch (rheostat). This signals the headlamp leveling motors (headlamp module mounted) to adjust the vertical headlamp beam pattern accordingly. Headlamps must be "ON" in order for the leveling system to function.
