Ford Expedition (2018 year). Manual — part 81

After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.

Note:

Prior to relearning the battery state

of charge, the battery management system
may temporarily disable some electrical
systems.

Electrical Accessory Installation

To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.

Note:

If you add electrical accessories or

components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

ADJUSTING THE HEADLAMPS

Vertical Aim Adjustment

The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident,
contact an authorized dealer to check and
realign your headlamps.

Vertical Aim Adjustment

1.

Park your vehicle directly in front of a
wall or screen on a level surface,
approximately 25 ft (7.6 m) away.

2. Measure the height from the center of

your headlamp (indicated by a 3 mm
circle on the lens) to the ground and
mark an 8 ft (2.4 m) horizontal
reference line on the vertical wall or
screen at this height (a piece of
masking tape works well).

Note:

To see a clearer light pattern for

adjusting, you may want to block the light
from one headlamp while adjusting the
other.

3. Switch on the low beam headlamps to

illuminate the wall or screen and open
the hood. Cover one of the headlamps
so no light hits the wall.

E167358

4. For halogen or LED headlamps: On

the wall or screen you will observe a
light pattern with a distinct horizontal
edge toward the right. If this edge is not
at the horizontal reference line, you will
need to adjust the beam so the edge
is at the same height as the horizontal
reference line.

5. Locate the vertical adjuster on each

headlamp. Use a #2 Phillips
screwdriver to turn the adjuster either
counterclockwise or clockwise in order
to adjust the vertical aim of the
headlamp.

other headlamp.

7.

Close the hood and turn off the lamps.
