6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
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, with a higher center of gravity, 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 has the capability to 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.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating (GCWR)
chart (in the
Trailer towing
section) to find the maximum GCWR for
your type engine and rear axle ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
TRAILER TOWING
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing:
•
Stay within your vehicle’s load limits.
•
Thoroughly prepare your vehicle for towing. Refer to
Preparing to
tow
in this chapter.
