²The Front Axle Accessory Reserve Capacity and the Total Accessory
Reserve Capacity listed on the bottom right of the Safety Compliance
Certification Label will determine whether or not the addition of a
snowplow will overload your vehicle.
²The weight of the snowplow and supporting components distributed to
the front axle must not exceed the front accessory reserve capacity.
²The total weight of the snowplow and aftermarket equipment must
not exceed the Total Accessory Reserve Capacity.
²The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
²The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the Gross
Combined Weight Rating (GCWR) for towing.
²Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
²After installing a snowplow to the vehicle, ensure the vehicle's front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle's Workshop
Manual. Adherence to the toe, tire pressures and ride height
specification is important for proper tire wear, ride, handling and
headlight aim. Also, maintain the engine oil and transmission fluid
change intervals following the severe duty schedule.
Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.
Removing snowplow
Read the following instructions before removing a snowplow:
²After removing a snowplow from the vehicle, ensure the vehicle's front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle's Workshop
Manual. Adherence to the toe and ride height specification is
important for proper tire wear, ride, handling and headlight aim.

Snowplowing with your air bag equipped vehicle
Your vehicle is equipped with driver
and passenger air bags. The air bags
are designed to deploy in a collision
with a solid barrier at a range of
13 to 23 km/h (8 to 14 mph) or a
parked car at a range of 25 to
45 km/h (16 to 28 mph).
Careless or high speed driving while plowing snow which results in
vehicle decelerations equivalent 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
properly wear their safety belts, even when an air bag SRS is
provided.
Never remove or defeat the ªtripping mechanismsº 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.

Driving
147

If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
Transmission operation while plowing
²Shift transfer case to 4L (4WD Low) when plowing in small areas at
speeds below 8 km/h (5 mph).
²Shift transfer case to 4H (4WD High) when plowing larger areas or
light snow at higher speeds. Do not exceed 24 km/h (15 mph).
²Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
²If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.

HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle breakdown,
approaching danger, etc. The hazard flashers can be operated when the
ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn the
flashers off.
FUEL PUMP SHUT-OFF SWITCH
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated. The ªFuel Resetº indicator light
will illuminate in the instrument cluster. The shut-off switch is a device
intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

CHANGING THE TIRES
If you get a flat tire while driving, 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 wheel may not match the road wheel, and is
not equipped with wheel trim. The wheel trim from the wheel/tire may
be used on the spare if the wheels match.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Such a tire could
result in damage to driveline components and make the vehicle
difficult to control.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire Under the vehicle, just forward of the rear
bumper
Jack, lug nut wrench Under the seat
Jack handle On top of the radiator support at the front of
the engine compartment
Roadside emergencies
157

Refer to the instruction sheet (located under the passenger front seat
with the jack) for detailed tire change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
(automatic transmission) or in the
reverse gear (manual transmission)
and turn engine OFF.
3. Block the diagonally opposite
wheel.
4. Obtain the spare tire and jack
from their storage locations.
5. Use the tip of the lug wrench to
remove any wheel trim.
6. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.

²Front (4x4)
²Rear
To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
²Never use the front or rear
differential as a jacking point.
9. Remove the lug nuts with the lug wrench.
10. Replace the flat tire with the spare tire, making sure the valve stem
is facing outward. 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.
11. Lower the wheel by turning the jack handle counterclockwise.
