Operating the vehicle with the snowplow attached
Do not use your vehicle for snow removal until it has been driven at
least 500 miles (800 km).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature:
• If you are driving more than 15 miles (24 km) where outside air
temperatures are above freezing, then angle the plow blade to full left
or right to maximize airflow to the radiator.
• If you are driving less than 15 miles (24 km) at speeds up to 40 mph
(64 km/h) in cold weather you will not need to adjust blade position
Follow the severe duty schedule in your scheduled maintenance
information for engine oil and transmission fluid change intervals.
Snowplowing with your airbag-equipped vehicle
Your vehicle is equipped with a driver and passenger airbag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the airbag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
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 airbag deployment.
Do not attempt to service, repair, or modify the air bag
supplemental restraint system (SRS) or its fuses. See your Ford
or Lincoln Mercury dealer.
Additional equipment such as snowplow equipment may effect
the performance of the airbag sensors increasing the risk of
injury. Please refer to the Body Builders Layout Book for instructions
about the appropriate installation of additional equipment.

6. Make another check for leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note: Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire. 15

Passenger compartment fuse panel
The fuse panel is located below and to the left of the steering wheel by
the brake pedal. Remove the panel cover to access the fuses.
To remove the fuse panel cover, pull
the panel downward by the finger
slots on top of the panel. When the
top clips of the panel disengage, let
the panel fall easily.

To remove a fuse use the fuse puller
tool provided on the fuse panel
cover.
To reinstall the cover, align and
engage the two hooked clips at the
bottom of the cover onto the
instrument panel, then lift the panel
and press the top clips firmly into
place.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the passenger compartment fuse
panel before reconnecting the battery.
If the battery has been disconnected and reconnected, refer to the
Battery section of the Maintenance and Specifications chapter.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, always replace the cover to
the Power Distribution Box before reconnecting the battery or
refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Battery section of the Maintenance and Specifications chapter.
