Headlamp Leveling System

The Remote Headlamp Leveling System allows the driver to adjust the headlamp beam pattern from the interior of the vehicle to compensate for passenger or cargo load. Only the vertical axis of the headlamp beam can be adjusted.

A Headlamp Leveling Switch is located on the Instrument Panel and controls the headlamp leveling motors/modules found on the headlamp modules. The Leveling Switch has two settings 0-1, 0 being the lowest, 1 being the highest headlight beam vertical setting.

NOTE: When performing a headlamp beam pattern alignment on a vehicle equipped with headlamp leveling, be certain the Headlamp Leveling Switch is in the "0" position before starting. Failure to do so will result in an incorrect headlamp alignment.

Moving the Headlamp Leveling Switch control knob will adjust the voltage sent to the headlamp leveling motors. This signals the headlamp leveling motors to move and adjust the vertical headlamp beam pattern accordingly. The headlamp switch must be "ON" in order for the leveling system to function. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
