integral screw-drive transmission. The ball on the end of the pushrod is snapped into a socket on the back of the
reflector within the front lamp unit housing, which will cause the reflector to move as the pushrod is extended
or retracted, changing the angle at which the light is projected from the headlamp low beam bulb filaments.
The hard wired circuits for the headlamp leveling motors may be diagnosed using conventional diagnostic tools
and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will
not prove conclusive in the diagnosis of the active electronic elements within the headlamp leveling motors or
the electronic controls and communication between other modules and devices that provide some features of the
headlamp leveling system. The most reliable, efficient, and accurate means to diagnose the headlamp leveling
motor or the electronic controls and communication related to headlamp leveling system operation requires the
use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

The headlamp leveling switch (3) is used only on vehicles manufactured for certain markets where the
headlamp leveling system is required. The headlamp leveling switch is integral to the switch pod (1) on the
instrument panel. A stencil-like International Control and Display Symbol icon for Headlamp Levelling
Control identifies the headlamp leveling switch button. The switch push button is also marked with the
numbers 0 , 1 , 2 , and 3 , which indicates each of the four headlamp leveling positions. Each higher number
represents a lower aiming position of the headlamp beam relative to the road surface.
The headlamp leveling switch button has panel lamps dimmer controlled illumination for night visibility. The
switch button also features a jewel like Light Emitting Diode (LED) indicator adjacent to the numbers 1 , 2 ,
and 3 . The appropriate LED is illuminated when that headlamp position is currently selected. The momentary
switch push button is operated by depressing, then releasing the top or bottom of the button in a rocker manner
to enable the selection of a sequentially higher or lower position with each button press.
All of the circuitry and components of the headlamp leveling switch are contained within a molded black plastic
instrument panel switch pod housing. A single connector receptacle is integral to the back of the switch pod
housing. The switch is connected to the vehicle electrical system through a dedicated take out and connector of
the instrument panel wire harness.
The headlamp leveling switch cannot be adjusted or repaired and, if ineffective or damaged, the entire
