See Weight-Distributing Hitch
Adjustment under Towing
Equipment 0 322 to determine
if equalizer bars are required
to obtain the maximum trailer
weight rating.
See Trailer Brakes under
Towing Equipment 0 322 to
determine if brakes are
required based on the trailer
weight.
The only way to be sure the
weight is not exceeding any of
these ratings is to weigh the
tow vehicle and trailer
combination, fully loaded for
the trip, getting individual
weights for each of these
items.
Warning
You and others could be
seriously injured or killed if
the trailer is too heavy or
the trailer brakes are
inadequate for the load. The
vehicle may be damaged,

covered by the vehicle
warranty.
Only tow a trailer if all the
steps in this section have
been followed. Ask your
dealer for advice and
information about towing a
trailer.
Gross Combined Weight
Rating (GCWR)
GCWR is the total allowable
weight of the completely
loaded vehicle and trailer
including any fuel, passengers,
cargo, equipment, and
accessories. Do not exceed
the GCWR for your vehicle.
The GCWR for the vehicle is
on the Tow Rating Chart
following.
Driving and Operating
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits 0 242. 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.
Use the tow rating chart to
determine how much the
trailer can weigh, based on the
vehicle model and options.
