installed, the dimmer control requires re-calibration. Press the dimmer
control from the full dim position to the full on position to reset. This
will ensure that your displays are visible under all lighting conditions.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Vertical aim adjustment
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height of the
headlamp bulb center from the
ground and mark an 8 foot
(2.4 meter) horizontal reference line
on the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
To see a clearer light pattern for adjusting, you may want to block the
light from one headlamp while adjusting the other.

Welcome and farewell lighting are included in the Lincoln white signature
color. The transition from signature color to ambient occurs when the
key is placed in the ignition and all doors are closed. Farewell lighting
occurs when the key is removed from the ignition and the driver door is
opened.
Note:The ambient color will stay on until after the ignition is placed in
the off position and either of the front doors are opened or the accessory
delay timer expires. At that time, the ambient color changes to the
signature color.
BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to dealer for service if any of the above conditions of
unacceptable moisture are present.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

see your authorized dealer.
Replacing stop/tail/turn and side marker bulbs
Your vehicle is equipped with a rear lamp that has a stop/tail/turn and
side marker lamp module containing integral multiple light emitting
diodes (LED). If one or more LEDs burn out, the complete lamp module
has to be replaced. See your authorized dealer for the replacement lamp.

side trim panel) outboard to expose the lamp assembly. The most
effective point to grasp the trunk side panel when pulling it out from the
luggage scuff plate is at it’s bottom edge where that edge meets the
exposed sheet metal of the trunk floor.
Note:Do not allow the trunk side panel to remain bent and untucked
from the luggage scuff plate (hard molding) for a long period of time.
Doing so may result in permanent deformation.
4. Remove the bulb socket by
rotating it counterclockwise, then
pulling it out of the lamp assembly.
5. Pull the bulb from the socket and
push in the new bulb.
6. Install the bulb socket into the
lamp assembly by rotating it
clockwise.
7. Carefully push the trunk side
panel (dark grey, soft wheelhouse
side trim panel) back to the shingle position to the luggage scuff plate
(hard molding).
8. Reinstall the trunk floor carpeting panel.
