AIR FILTER CHECK
WARNING: To reduce the risk of vehicle damage and or
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. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
When changing the air filter element, use only the air filter element
listed. See Motorcraft® Part Numbers in theCapacities and
Specifications chapter.
See Scheduled Maintenance Information for the appropriate intervals
for changing the air filter element.
Note: Failure to use the correct air filter element may result in severe

Changing the Air Filter Element1. Locate the mass air flow sensor
electrical connector on the air
outlet tube. This connector will
need to be unplugged.
2. Unlock the locking clip on the
connector (connector shown from
below for clarity), then squeeze and
pull the connector off of the air
outlet tube.
3. Clean the area around the air
tube to air cover connection to
prevent debris from entering the
system and then 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 vehicle and up slightly to release it.6. Remove the air filter element
from the air filter housing.
7. Install a new air filter element.
8. Replace the air filter housing
cover and secure the clamps. Be
careful not to crimp the filter
element edges between the air filter
housing and cover and ensure that
the tabs on the edge are properly
aligned into the slots.
9. Slip the air tube onto the air
filter housing and tighten the
air-tube clamp bolt snugly, but do
not overtighten it.
10. Reconnect the mass air flow
sensor electrical connector to the
outlet tube. Make sure the locking
tab on the connector is in the
“locked” position (connector shown
from below for clarity).

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
Vertical Aim Adjustment
Before aim adjustment, disable the air suspension system. Refer to
Message centerin theDriver Controls chapter.
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away. •(A) 8 feet (2.4 meters)
• (B) Center height of lamp to
ground
• (C) 25 feet (7.6 meters)
• (D) Horizontal reference line
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).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light from that lamp
hits the wall.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.

5. Locate the vertical adjuster on
each headlamp, then use a Phillips
#2 screwdriver to turn the adjuster
either counterclockwise or
clockwise in order to adjust the
vertical aim of the headlamp. The
upper edge of the light pattern
should touch the horizontal
reference line.
6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT ADJUSTABLE.
7. Repeat Steps 3–5 for the other headlamp.
8. Close the hood and turn off the lamps.
CHANGING A BULB
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.
These are examples of acceptable condensation:
• Presence of thin mist (no streaks, drip marks or droplets).
• Fine mist covers less than 50% of the lens.
These are examples of unacceptable moisture (usually caused by a lamp
water leak):
• Water puddle inside the lamp.
• Large water droplets, drip marks or streaks present on the interior of
the lens.
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
