(4) Pull leveling motor straight from headlamp
unit. Significant force will be required to unsnap
motor control arm from lens reflector.
NOTE: The headlamp leveling motor control arm is
snapped into the lens reflector mechanism very
securely. Use a firm, steady pull to disengage motor
arm from reflector.
(5) Remove leveling motor from headlamp unit.

INSTALLATION

(1) While holding headlamp reflector assembly
still, push leveling motor until control arm is fully
seated into reflector mechanism. An audible "snap"
will be heard.
(2) Push and rotate leveling motor one quarter
turn clockwise to lock motor to the headlamp unit.
(3) Connect headlamp leveling motor electrical
connector.
(4) Install headlamp unit in the vehicle (Refer to 8

HEADLAMP LEVELING
SWITCH - EXPORT
DESCRIPTION
This Headlamp Leveling Switch is located in the
accessory switch bezel (Fig. 22), located on the
instrument panel. The switch is the primary control-
ler of the headlamp leveling system. The leveling
switch has four settings 0-3, 0 being the lowest, and
3 being the highest headlight beam vertical setting.

OPERATION

With the rotation of the headlamp leveling switch
control knob (Fig. 22), voltage is adjusted at the
headlamp leveling switch (rheostat). This signals the
headlamp leveling motors (headlamp unit mounted)
to adjust the vertical headlamp beam pattern accord-
ingly. Headlamps must be ON in order for the level-
ing system to function.
