tab on the connector is in the
“locked” position (connector shown

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Vertical Aim Adjustment
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.

7. Turn the jack handle clockwise
until the wheel is completely off the
ground and high enough to install
the spare tire.

wrench.
9. Replace the flat tire with the spare
tire, making sure the valve stem is
facing outward for all front wheels
and single rear wheel vehicles. If
replacing an inboard rear tire on dual rear wheel vehicles, the valve stem
must be facing outward. If replacing the outboard wheel, the valve stem
must be facing inward. Reinstall the lug nuts until the wheel is snug against
the hub. Do not fully tighten the lug nuts until the wheel has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.
Go to Step 19.
The following steps apply to F–350 Dual Rear Wheel (DRW) and
F–450/F–550 vehicles only:
11. Slide the notched end of the
jack handle over the release valve
and use the handle to slide the jack
under the vehicle. Make sure the
valve is closed by turning it
clockwise.
12. Position the jack according to
the following guides:
•Front (4x2): F–350 DRW
Note:Place the jack directly under
I-beam.
