²license plate lamp
²tail lamps
²back-up lamps
Do not remove lamp bulbs unless
they can be replaced immediately
with new ones. If a bulb is
removed for an extended period of
time, contaminants may enter the
lamp housings and affect lamp
performance.
Replacing headlamp bulbs
Handle a halogen
headlamp bulb carefully
and keep out of children's reach.
Grasp the bulb only by its plastic
base and do not touch the glass.
The oil from your hand could
cause the bulb to break the next
time the headlamps are
operated.
If the bulb is accidentally
touched, it should be cleaned
with rubbing alcohol before
being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position, then open the hood.
If you are replacing the driver side
headlamp, unclip the electronic
module on the right side of the
battery and move it out of the way.
2. Locate the headlamp bulb
through the hole in the upper
radiator support assembly.

3. Push the electrical connector
into the rear of the plastic base
until it snaps, locking it into
position.
4. Turn the headlamps on and
make sure they work properly. If
the headlamp was correctly aligned
before you changed the bulb, you
should not need to align it again.

AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp. Each
headlamp may be properly aimed
in the vertical (up/down) and the
horizontal (left/right) directions
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant, and vertical and horizontal
indicators of the VHAD system are
calibrated.
A bubble (vertical indicator) that
is not centered between the two
red lines does not necessarily
indicate out-of-aim headlamps. If
your vehicle is not positioned on a
level surface, the slope will be
included in the vertical indication.
Therefore, vertical and horizontal
headlamp adjustment should be
performed only when the beam
direction appears to be incorrect.
You will need one 4 mm wrench or
socket with ratchet to make the
adjustments.
The following procedure assumes
that the factory set horizontal
indicator reference has not
changed and the vehicle's front
structure is in its factory alignment
condition. If the vehicle has been
in an accident requiring the front
end of the vehicle to be repaired,
the horizontal indicator should be
recalibrated by the servicing
facility according to instructions in
the vehicle's Workshop Manual.

Horizontal aim adjustment
1. With the hood open, locate the
horizontal indicator and adjusting
screw. They are located below the
viewing hole at the rear of the
headlamp assembly.
2. Use a 4mm wrench or socket to
turn the horizontal adjusting screw
until the ª0º mark on the yellow
dial lines up with the reference
mark on the marker (as shown)
when viewed directly from above.
Vertical aim adjustment
1. Park the vehicle on a level
surface.
2. With the hood open, locate the
bubble level and vertical
adjustment screw. The adjustment
screw is located on the outboard
side of the headlamp.
3. The ªUPº and ªDNº on the
bubble indicate the directional
change (up or down) of the
vertical aim.
4.Usea4mmwrench or socket to
turn the vertical adjusting screw
clockwise or counterclockwise until
the bubble is centered over the ª0º
mark.

CLEANING AND CARING FOR
YOUR VEHICLE
Refer to the ªCustomer Assistance
Guideº for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of
water for best results. To avoid
spots, avoid washing when the
hood is still warm, immediately
after or during exposure to strong
sunlight.
During winter months, it is
especially important to wash the
vehicle on a regular basis. Large
quantities of dirt and road salt are
difficult to remove and also cause
damage to the vehicle. Remove any
exterior accessories, such as
antennas, before entering a car
wash.
After washing, apply the brakes
several times to dry them.
Waxing your vehicle
Wax when water stops beading on
the surface. This could be every
three or four months, depending
on operating conditions.
