2010 FORD F250 SUPER DUTY open hood

To adjust the headlamps:
1. Park your vehicle on a level
surface about 25 feet (7.6 meters)
away from a vertical plain surface
(3). Check your headlamp alignment
at night or in a dark area so that
you can see the headlamp beam
pattern.
• (1) 8 feet (2.4 meters)
• (2) Center height of lamp to
ground
• (3) 25 feet (7.6 meters)
• (4) Horizontal reference line
• (5) Center of headlamps
• (6) Center line of the vehicle
2. The center of the headlamp is marked either on the lens (a circle or
cross marker) or on the bulb shield, internal to the lamp (mark or
feature). Measure the height from the center of your headlamp to the
ground (2) and mark an 8 foot (2.4 meter) long horizontal line on the
wall or screen (1) at this height (masking tape works well).
3. Turn on the low beam headlamps
and open the hood.
4. Locate the high intensity area of
the beam pattern and place the top
edge of the intensity zone even with
the horizontal reference line (4). If
the top edge of the high intensity
area is not even with the horizontal
line, follow the next step to adjust
it.Lights

• (4) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 mm 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 E5 Torx
socket to turn the adjuster either
counterclockwise (to adjust down)
or clockwise (to adjust up) aligning
the upper edge of the light pattern
up to the horizontal line.
6. Repeat Steps 3–5 for the other
headlamp.
7. Close the hood and turn off the
lamps.
TURN SIGNAL CONTROL

turn signal.

PERIMETER ALARM SYSTEM (IF EQUIPPED)
The perimeter anti-theft system will warn you in the event of an
unauthorized entry to your vehicle.
If there is any potential perimeter anti-theft problem with your vehicle,
ensure ALL remote entry transmitters are taken to the authorized
dealer to aid in troubleshooting.
Arming the system
When armed, this system will respond if unauthorized entry is
attempted. When unauthorized entry occurs, the system will flash the
park/turn lamps and will sound the horn.
The system is ready to arm whenever the key is removed from the
ignition. Either of the following actions will prearm the alarm system:
• Press the control on the remote entry transmitter.
• Open a door and press the power door lock control to lock all the
doors, and then close the door.
• Press and hold the 7 • 8 and 9 • 0 controls on the keyless entry pad
at the same time to lock the doors (driver’s door must be closed).
There is a 20 second countdown when any of the above actions occur
before the vehicle becomes armed.
Each door and the hood is armed individually, and if any are open, they
must be closed before the open entry point can enter the 20 second
countdown.
The turn signal lamps will flash once when all doors and the hood are
closed indicating the vehicle is locked and entering the 20 second
countdown.Locks and Security
