See Weight of the Trailer Tongue
later in this section for more
information.
Trailer weight rating (TWR) is
calculated assuming the tow vehicle
has the driver, a front seat
passenger, and all required trailering
equipment. Weight of additional
optional equipment, passengers,
and cargo in the tow vehicle must
be subtracted from the trailer weight
rating.
Ask your dealer for trailering
information or advice. For kingpin
weight and trailer tongue weight
information, see Weight of the
Trailer Tongue later in this section.
Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model and
options.

Trailering Provisions
For trailers without trailer brakes the maximum trailer weight is 454 kg
(1,000 lb). See Towing Equipment 0 250.
* The Gross Combination Weight Rating (GCWR) is the total allowable
weight of the completely loaded vehicle and trailer including any
passengers, cargo, equipment, and conversions. Do not exceed the
GCWR for the vehicle.
Ask your dealer for trailering
information or advice.
Weight of the Trailer Tongue
The tongue load (1) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people

who will be riding in the vehicle.
If there are a lot of options,
equipment, passengers, or cargo in
the vehicle, it will reduce the tongue
weight the vehicle can carry, which
will also reduce the trailer weight the
vehicle can tow. If towing a trailer,
the tongue load must be added to
the GVW because the vehicle will
be carrying that weight, too. See
Vehicle Load Limits 0 177.
