The telescoping feature (if equipped) allows the mirror to extend
approximately 3.15 inches (80 mm). This feature is especially useful to
the driver when towing a trailer.
POWER ADJUSTABLE FOOT PEDALS (IF EQUIPPED)
The accelerator and brake pedal
should only be adjusted when the
vehicle is stopped and the gearshift
lever is in the P (Park) position.
Press and hold the rocker control to
adjust accelerator and brake pedal
toward you or away from you.
The adjustment allows for approximately 3 inches (71–76 mm) of
maximum travel.
Never adjust the accelerator and brake pedal with feet on the
pedals while the vehicle is moving.
SPEED CONTROL (IF EQUIPPED)
With speed control set, you can maintain a speed of 30 mph (48 km/h)
or more without keeping your foot on the accelerator pedal. Speed
control does not work at speeds below 30 mph (48 km/h).
Do not use the speed control in heavy traffic or on roads that
are winding, slippery or unpaved.
Setting speed control
The controls for using your speed
control are located on the steering
wheel for your convenience.
1. Press the ON control and release
it.

•The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Certification Label. This applies to
Ford-completed vehicles of 10,000 lb. GVWR or less. This is the
weight of permanently-attached auxiliary equipment, such as
snowplow frame-mounting hardware, that can be added to the vehicle
and satisfy Ford compliance certification to FMVSS. Exceeding this
weight may require the auxiliary equipment installer additional safety
certification responsibility. The Front Accessory Reserve Capacity
(FARC) is added for customer convenience.
•Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
•Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the FordWorkshop
Manual.
•Headlight aim may require re-adjustment.
•The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted 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 dealer for additional
information.
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 yourScheduled Maintenance Guide
for engine oil and transmission fluid change intervals.
Snowplowing with your air bag-equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
