²Payload: Combined maximum allowable weight of
cargo, passengers and optional equipment. The
payload equals the gross vehicle weight rating
minus base curb weight.
²GVW (Gross Vehicle Weight): Base curb weight
plus payload weight. The GVW is not a limit or a
specification.
²GVWR (Gross Vehicle Weight Rating):
Maximum total weight of the base vehicle,
passengers, optional equipment and cargo. The
GVWR is specific to each vehicle and is listed on
the Safety Compliance Label on the driver's door
pillar.
²GAWR (Gross Axle Weight Rating): Carrying
capacity for each axle system. The GAWR is
specific to each vehicle and is listed on the Safety
Compliance Label on the driver's door pillar.
²GCW (Gross Combined Weight): The combined
weight of the towing vehicle (including passengers
and cargo) and the trailer.
²GCWR (Gross Combined Weight Rating):
Maximum combined weight of towing vehicle
(including passengers and cargo) and the trailer.
The GCWR indicates the maximum loaded weight
that the vehicle is designed to tow.
²Maximum Trailer Weight Rating: Maximum
weight of a trailer the vehicle is permitted to tow.
The maximum trailer weight rating is determined
by subtracting the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight of
the driver from the GCWR for the towing vehicle.
²Maximum Trailer Weight: Maximum weight of a
trailer the loaded vehicle (including passengers
and cargo) is permitted to tow. It is determined
by subtracting the weight of the loaded trailer
towing vehicle from the GCWR for the towing
vehicle.

²Trailer Weight Range: Specified weight range
that the trailer must fall within that ranges from
zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your
loaded trailer when figuring the total weight.
Do not exceed the GVWR or the GAWR
specified on the Safety Compliance
Certification Label.
Do not use replacement tires with lower load
carrying capacities than the originals because they
may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit
than the originals do not increase the GVWR and
GAWR limitations.
The Certification Label, found on the inside pillar of
the driver's door, lists several important vehicle
weight rating limitations. Before adding any
additional equipment, refer to these limitations. If
you are adding weight to the front of your vehicle,
(potentially including weight added to the cab), the
weight added should not exceed the Front Axle
Reserve Capacity (FARC). Additional frontal weight
may be added to the front axle reserve capacity
provided you limit your payload in other ways (i.e.
restrict the number of passengers or amount of
cargo carried).
You may add equipment throughout your vehicle if
the total weight added is equal to or less than the
Total Axle Reserve Capacity (TARC) weight. You
should NEVER exceed the Total Axle Reserve
Capacity.
Always ensure that the weight of passengers, cargo
and equipment being carried is within the weight
limitations that have been established for your
vehicle including both Gross Vehicle Weight and
Front and Rear Gross Axle Weight Rating limits.
Under no circumstance should these limitations be
exceeded. Exceeding any vehicle weight rating
