Ford F-250 Light Duty - 1998 Fuse Box Diagram

The right front passenger
air bag is not designed to
restrain occupants in the center
front seating position.
All occupants of the
vehicle including the driver
should always wear their safety
belts even when air bag SRS is
provided.
Do not place objects or
mount equipment on or
near the air bag cover on the
steering wheel or in front seat
areas that may come into contact
with a deploying air bag. Failure
to follow this instruction may
increase the risk of personal
injury in the event of a collision.
Do not attempt to service,
repair, or modify the Air
Bag Supplemental Restraint
System or its fuses. See your
Ford or Lincoln-Mercury dealer.
Children and air bags
For additional important safety
information, read all information
on safety restraints in this guide.
Children should always wear their
safety belts. Failure to follow these
instructions may increase the risk
of injury in a collision.

is possible that a fuse has blown
and the vehicle’s brakelamps may
not be operating properly. Refer to
Fuses and relays
in the
Roadside
emergencies
chapter.
Do not drive your vehicle
until you verify that the
brakelamps are working.
If your vehicle gets stuck in mud
or snow it may be rocked out by
shifting from forward and reverse
gears in a steady pattern. Press
lightly on the accelerator in each
gear.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine may
overheat.
Always set the parking
brake fully and make sure
the gearshift is latched in P
(Park). Turn off the ignition
whenever you leave your vehicle.
Driving with a 4–speed

to or greater than the air bag
deployment impact speeds listed
above can deploy the air bag. Such
driving also increases the risk of
accidents.
All occupants of the
vehicle, including the
driver, should always wear their
safety belts.
Never remove or defeat the
“tripping mechanisms” designed
into the snow removal equipment
by its manufacturer. Doing so may
cause damage to the vehicle and
the snow removal equipment as
well as possible air bag
deployment.
Do not attempt to service,
repair, or modify the Air
Bag Supplemental Restraint
System or its fuses. See your
Ford or Lincoln-Mercury dealer.
Engine temperature while
plowing
When driving with a plow, your
engine may run at a higher
temperature than normal because
the attached snowplow blade will
restrict airflow to the radiator.
If you are driving more than 24 km
(15 miles) at temperatures above
freezing, angle the plow blade

do not apply the brake heavily.
Instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.
Spare tire information
Your vehicle is equipped with a
spare tire that may be used as a
spare or a regular tire. The spare
tire is not equipped with wheel
trim. The wheel trim from the
original wheel/tire may be used on
the spare.
