240 DRIVING AND OPERATING
Gross Vehicle Weight
Rating (GVWR)
For information about the vehicle's
maximum load capacity, see Vehicle
Load Limits 0 176. When calculating
the GVWR with a trailer attached, the
trailer tongue weight must be
included as part of the weight the
vehicle is carrying.
Maximum Trailer Weight
The maximum trailer weight rating is
calculated assuming the tow vehicle
has a driver, a front seat passenger,
and all required trailering equipment.
This value represents the heaviest
trailer the vehicle can tow, but it may
be necessary to reduce the trailer
weight to stay within the GCW,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
Ask your dealer for trailering
information or assistance.
Maximum Trailer Tongue Weight
Rating
The Maximum Trailer Tongue Weight
Rating is the allowable trailer tongue
weight that the vehicle can support
using a conventional trailer hitch.
It may be necessary to reduce the
overall trailer weight to stay within
the maximum trailer tongue weight
rating while still maintaining the
correct trailer load balance.
The trailer tongue weight contributes
to the Gross Vehicle Weight (GVW).
GVW includes the curb weight of your
vehicle, any passengers, cargo,
equipment and the trailer tongue
weight. Vehicle options, passengers,
cargo, and equipment reduce the
maximum allowable tongue weight
the vehicle can carry, which also
reduces the maximum allowable
trailer weight.
Trailer Load Balance
The correct trailer load balance must
be maintained to ensure trailer
stability. Incorrect load balance is a
leading cause of trailer sway.
The trailer tongue weight (1) should
be 10 15% of the loaded trailer
weight (2). Some specific trailer types,
such as boat trailers, fall outside of
this range. Always refer to the trailer
owner s manual for the recommended
