Special loading instructions for owners of pickup trucks and
utility-type vehicles
WARNING: For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your vehicle
section in the Driving chapter of this Owner’s Guide.
WARNING: Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a heavily
loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Note: The trailer towing charts in this section apply to vehicles equipped
with gasoline engines; for vehicles equipped with diesel engines, refer to
your Power Stroke Direct Injection Turbo Diesel Owner’s Guide
Supplement.
Your vehicle may tow a Conventional/Class IV trailer or fifth wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight listed for your engine and rear axle ratio on the
following charts.
To calculate your maximum trailer weight:
For pickup trucks: Take curb weight, hitch hardware and the driver’s
weight, then subtract them from the GCWR listed for your vehicle series,
engine, transmission and drive axle ratio (refer to the chart/table in the
following text). This calculation will give you the maximum trailer
weight possible for your vehicle.
For chassis cabs and pickup trucks with aftermarket equipment:
Weigh your vehicle at a certified scale and subtract this actual curb
weight, hitch hardware, and the driver’s weight from the GCWR listed for
your vehicle series, engine, transmission and drive axle ratio (refer to
2009 F-250/350/450/550 (f23)
