Maximum Trailer Weight
The maximum trailer weight is the maximum
weight of a trailer the loaded vehicle is
permitted to tow. It is determined by subtracting
the weight of the loaded towing
vehicle (including passengers and cargo) from
the GCWR for the towing vehicle.
Trailer Weight Range
The trailer weight range is a specified range by
weight, which the trailer must fall within,
ranging from zero to the maximum trailer
weight rating.
Calculating The Load
To know how much weight your vehicle can
carry:
Obtain ratings from your Safety Compliance
Certification Label, and the Trailer towing
specifications in the owner guide (refer to the
Index)
— Refer to the following sample illustration
to locate the various ratings on your
Safety Compliance Certification Label.
— If you do not plan on pulling a trailer, do
not include these ratings into your
calculations.
Weigh your vehicle as you customarily
operate the vehicle (without cargo).
Subtract the total weight of passengers, driver
and optional equipment added by the factory,
dealer or aftermarket supplier to determine
how much cargo weight you can carry.
