Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see the Preparing to drive your vehicle section in
this chapter.
Loaded vehicles mayhandle differentlythan unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavilyloaded 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 mayraise the center of gravityof the vehicle.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum GCWR chart (in the Trailer Towing
section in this chapter) for your type of engine and rear axle ratio.
2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping companyor an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Your vehicle maytow 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.
2nd unit bodies are not included in maximum trailer weight ratings. The
weight of the additional “body” must be subtracted from the maximum
trailer weight.
Your vehicle’s load capacityis designated byweight, not byvolume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefullyprior to and after anytowing operation. The
following trailer towing charts applyto vehicles equipped with gasoline
engines; for Diesel engines, refer to the 7.3 Liter Power Stroke Direct
Injection Turbo Diesel Supplement.
