2. Measure the height from the center of
your headlamp (indicated by a 3.0
millimeter circle on the lens) to 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).
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. 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. 6. Repeat Steps 3 through 7 to adjust the
other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this vehicle
and is not adjustable.

CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not start
your engine with the air cleaner removed
and do not remove it while the engine is
running. Note:
Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage may
not be covered by the vehicle Warranty.
When changing the air filter element, use
only the air filter element listed. See
Motorcraft Parts (page 329).
Change the air filter element at the correct
interval. See Scheduled Maintenance (page
456
). 1.
Locate the mass air flow sensor electrical
connector on the air outlet tube.
Disconnect the mass air flow sensor
electrical connector. 2. Reposition the locking clip on the
connector (connector shown from below
for clarity), squeeze the connector and
pull it off of the air outlet tube. 3. Clean the area from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
loosen the bolt on the air tube clamp so
the clamp is no longer snug to the air
tube. It is not necessary to completely
remove the clamp.
4. Pull the air tube off from the air cleaner housing.

the air filter housing and cover and
ensure that you properly align the tabs
on the edge into the slots.
9. Slip the air tube onto the air filter housing
and tighten the air-tube clamp bolt
snugly. Do not over tighten air-tube
clamp bolt. 10. Reconnect the mass air flow sensor
