•
Inspect exhaust system for damage or
looseness.
• Inspect undercarriage fasteners. If any
are loose or damaged, tighten or
replace ensuring that the proper torque
specification is used.
• Inspect the tires for any cuts in the
tread or sidewall area. Also inspect the
sidewall for any bulge indicating
damage to the tire.
• Inspect the wheels for dents, cracks,
or other damage.
• Refit the front license plate if removed
previously.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Engine Oil Capacity and Specification
(page
449).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Engine damage can occur if water
enters the air filter.
For Vehicles without Tremor Off-
Road Package
Note: Driving through standing water can
cause vehicle damage.
Note: Drive through water in an emergency
only and not as part of normal driving.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.

•
The tire air pressures recommended
for general driving are on the vehicle ’s
Safety Certification Label. The
maximum cold inflation pressure for
the tire and associated load rating is
on the tire sidewall. Tire air pressure
may require re-adjustment within these
pressure limits to accommodate the
additional weight of the snowplow
installation.
• Federal and some local regulations
require additional exterior lamps for
snowplow-equipped vehicles. Consult
your authorized dealer for additional
information.
Operating the Vehicle with the
Snowplow Attached
Note: Do not use your vehicle for snow
removal until you have driven at least
500 mi (800 km).
Ford recommends vehicle speed does not
exceed
45 mph (72 km/h) when
snowplowing.
If transporting a snowplow in summertime,
cooling system airflow may be blocked by
the snowplow. Change the snowplow
height or position to improve airflow to the
radiator or limit your vehicle speed to a
maximum of
45 mph (72 km/h).
The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature:
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals. Snowplowing with your Airbag
Equipped Vehicle WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.
Note: Please refer to the Body Builders
Layout Book for instructions about the
appropriate installation of additional
equipment.
Your vehicle is equipped with a driver and
passenger airbag supplemental restraint
system. The supplemental restraint system
will activate in certain frontal and offset
frontal collisions when the vehicle sustains
sufficient frontal deceleration.
Careless or high speed driving while
plowing snow that results in sufficient
vehicle decelerations can deploy the
airbags. Such driving also increases the risk
of accidents.
