Maintenance and care

Do not remove lamp bulbs unless
they will be replaced immediately.
If a bulb is removed for an
extended period of time,
contaminants may enter the lamp
and affect 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.
1. Make sure that the headlamp
control is in the position.
2. Open the hood.
3. At the back of the headlamp,
pull clips rearward and up 19 mm
(about 3/4 in.) to release the
headlamp assembly.

plastic base and lock the ring into
the socket by turning it clockwise
until you feel a ªstop.º

AIMING HEADLAMPS
The alignment of your headlamps
should be checked if:
²Oncoming motorists frequently
signal you to turn off your
vehicle's high beams when you
do not have the high beams on.
²The headlamps do not seem to
give you enough light to see
clearly at night.
²The headlamp beams are
pointed substantially away from
a position slightly down and to
the right.
See your Ford dealer for precise
headlamp adjustment.
