VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the
following terms:
•Base Curb Weight:Weight of the vehicle
including any standard equipment, fluids,
lubricants, etc. It does not include occupants or
aftermarket equipment.
•Payload:Combined maximum allowable weight of
cargo, occupants and optional equipment. The
payload equals the gross vehicle weight rating
minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight
plus payload weight. The GVW is not a limit or a
specification.
•GVWR (Gross Vehicle Weight Rating):
Maximum permissible total weight of the base
vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed
on the Safety Certification Label on the driver’s
door pillar.
•GAWR (Gross Axle Weight Rating):Carrying
capacity for each axle system. The GAWR is
specific to each vehicle and is listed on the Safety
Certification Label on the driver’s door pillar.
•GCW (Gross Combined Weight):The
combined weight of the towing vehicle (including
occupants and cargo) and the loaded trailer.
•GCWR (Gross Combined Weight Rating):
Maximum permissible combined weight of towing
vehicle (including occupants and cargo) and the
loaded trailer
•Maximum 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.
•Maximum Trailer Weight:Maximum weight of a
trailer the loaded vehicle (including occupants

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.
•Trailer 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 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 Safety Certification Label, found on the driver’s
door pillar, 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 occupants or amount of cargo
carried).
Always ensure that the weight of occupants, 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
limitation could result in serious damage to
the vehicle and/or personal injury.
