Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% of the
total weight of the trailer is on the tongue.

Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a 25.4 mm (one inch) shank diameter. The bumper has a 2,270
kg (5,000 lb.) trailer weight and 227 kg (500 lb.) tongue weight capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•If your vehicle is equipped with a 4–speed automatic
transmission:To eliminate excessive transmission shifting, use a
lower gear. This will also assist in transmission cooling. (For additional
information, refer to theUnderstanding the positions of the 4–speed
automatic transmissionsection in this chapter.
•If your vehicle is equipped with a 5–speed automatic
transmission:To eliminate excessive transmission shifting, activate
the Tow/Haul feature. This will also assist in transmission cooling. (For
additional information, refer to theUnderstanding the positions of
the 5–speed automatic transmissionsection in this chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
Driving

ProCarManuals.com

•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
•Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants any time the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
ALL REAR WHEEL DRIVE (RWD) VEHICLES
This applies to all cars and 4x2 trucks/sport utilities with rear wheel
drive capability.
An example of recreational towing is towing your vehicle behind a
motorhome. The following recreational towing guidelines are designed to
ensure that your transmission is not damaged.
•Place the transmission in N (Neutral).
•Maximum speed is 56 km/h (35 mph).
•Maximum distance is 80 km (50 miles).
If a distance of 80 km (50 miles) or a speed of 56 km/h (35 mph) must
be exceeded, you must disconnect the driveshaft. Ford recommends the
driveshaft be removed/installed only by a qualified technician. See your
local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.

RWD vehicles with 4x4 electronic shift transfer case or All Wheel
Drive (AWD) vehicles with automatic transmissions:
Regarding recreational towing or having your vehicle towed, 4x4 vehicles
with electronic shift on the fly and AWD vehicles cannot be towed with
any wheels on the ground (with the exception of moving it as a disabled
vehicle off the road out of traffic).
SNOWPLOWING
Note:Do not use your vehicle to snowplow until it has been driven at
least 800 km (500 miles). Follow the severe duty schedule in your
scheduled maintenance guide for engine oil and transmission fluid
change intervals.
Note:Ford does not install snowplows.
For low speed snow removal, Ford offers a Snowplow Package Option on
select 4x4 vehicles. To assist Ford dealers and equipment installers
further prepare the vehicle for snowplowing, Ford includes instructions
in theFord Truck Body Builders Layout BookandFord Truck Source
Book. These instructions are available through your Ford dealer; they
include the list of vehicle models recommended for snowplowing and
snowplow weight limits. Use of the Snowplow Package Option, or its
equivalent, along with these instructions will help avoid possible
powertrain and chassis damage from snowplowing.
The front and rear GAWR, GVWR, Total Accessory Reserve Capacity
(TARC) and tire inflation pressures are found on the Safety Compliance
Certification Label located on one of the vehicle’s door jambs. This label
is applied to all vehicles completed by Ford Motor Company. Incomplete
vehicles built by Ford Motor Company will have an Incomplete Vehicle
Label in place of the Safety Compliance Label. The TARC does not apply
to Incomplete Vehicles and will not be shown on the Incomplete Vehicle
Label. The weight of the vehicle with occupants must never exceed the
front and rear GAWR or the GVWR.
The TARC is the weight of the permanently attached equipment that can
be added to the vehicle without violating the vehicle’s Safety Compliance
Certification. This includes the snowplow mounting hardware but does
not include the removable portion of the snowplow assembly.
Installing the snowplow
Read the following instructions before installing a snowplow:
•Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find your vehicle’s front GAWR.
Driving

•The Front Axle Accessory Reserve Capacity and the TARC 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.
•The weight of the snowplow and supporting components distributed to
the front axle must not exceed the Front Axle Accessory Reserve
Capacity.
•The total weight of the snowplow and aftermarket equipment must
not exceed the TARC.
•The 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.
•The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the GCWR for
towing.
•Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•Tires have their maximum inflation pressure and associated load rating
imprinted on the tire sidewall. This pressure may or may not be the
same as that shown as recommended on the vehicle. The vehicle
operator may have to adjust the tire inflation pressure to
accommodate the snowplow and payload. Consult your dealer or
equipment installer for help with proper inflation pressures.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
•After 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.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Removing snowplow
After removing a snowplow from the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required).
