2003 FORD F150 tow

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.
•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
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
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.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
An example of recreational towing would be towing your vehicle behind
a motorhome. Follow these guidelines if you have the need for
recreational towing your vehicle with all four wheels on the ground.
These guidelines are designed to ensure that your transmission is not
damaged.
Driving

2WD vehicles (with automatic transmissions):
•Place the transmission in N (Neutral)
•Maximum speed is 56 km (35 mph)
•Maximum distance is 80 km (50 miles)
If a distance of 80 km (50 miles) or a speed of 56 km (35 mph) must be
exceeded, the drive shaft will have to be removed before the vehicle is
towed.
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.
4WD vehicles electronic shift transfer case (with automatic
transmissions):
4x4 vehicles with electronic shift on the fly cannot be towed with any
wheels on the ground.
SNOWPLOWING
Ford recommends the following specifications for low speed, personal
use snow removal:
•F-150 4x4 (except F-150 Supercrew, Lightning and Harley-Davidson
models)
•5.4L engine
•Heavy-duty service package
•Super engine cooling
•Heavy-duty front suspension package
•Automatic transmission with auxiliary automatic transmission fluid
cooling
•All-terrain tires
•Limited slip and optional axle ratio.
Do not install a snowplow and plow with your vehicle until it has been
driven at least 800 km (500 miles).
Driving

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.
•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.
