Vehicle Load Limit: The maximum value of the combination weight of occupants and
cargo.
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall Area of the Tire: Area between the bead area and the tread.
Tread Area of the Tire: Area on the perimeter of the tire that contacts the road when it's

Vehicle Loading
WARNING
Do not tow a trailer with this vehicle:Towing a trailer with this vehicle is dangerous because it has not been designed to
tow a trailer and doing so will affect the drive system which could result in vehicle
damage.
This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its design rating capability. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading your vehicle,
familiarize yourself with the following terms for determining your vehicle's weight ratings,
from the vehicle's Safety Certification Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle: Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger safety. Too much weight on a vehicle's
suspension system can cause spring or shock absorber failure, brake failure,
handling or steering problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the
distance required for stopping. In cases of serious overloading, brakes can fail
completely, particularly on steep grades. The load a tire will carry safely is a
combination of the size of the tire, its load range, and corresponding inflation
pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certification and Tire and Load Information labels.

Base Curb Weight is the weight of the vehicle including a full tank of fuel and all
standard equipment. It does not include passengers, cargo, or optional equipment.
Vehicle Curb Weightis the weight of your new vehicle when you picked it up from your
dealer plus any aftermarket equipment.
PAYLOAD
Payload is the combination weight of cargo and passengers that the vehicle is designed to
carry. The maximum payload for your vehicle can be found on the Tire and Load
Information label on the driver's door frame or door pillar. Look for “THE
COMBINATION WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER
EXCEED XXX kg or XXX lbs” for your maximum payload. The payload listed on the tire
label is the maximum payload for the vehicle as built by the assembly plant. If any
aftermarket or dealer installed equipment has been installed on the vehicle, the weight of
the equipment must be subtracted from the payload listed on the tire label in order to be
accurate.

CARGO
Cargo Weightincludes all weight added to the Base Curb Weight, including cargo and
optional equipment.
The cargo weight limit decreases depending on the number of vehicle occupants. The cargo
weight limit can be calculated by subtracting the total weight of the vehicle occupants from
the “combination weight of occupants and cargo should never exceed ”value on the tire
label.

Examples: Based on a single occupant weight of 68 kg (150 lbs), and a value of 385 kg
(849 lbs) for the“combination weight of occupants and cargo should never exceed ”:
The cargo weight limit with one occupant is 385 kg (849 lbs) _
68 kg (150 lbs) = 317 kg
(699 lbs)
The cargo weight limit with two occupants is 385 kg (849 lbs) _
(68 × 2) kg ( (150 × 2)
lbs) = 249 kg (549 lbs)
If the weight of the occupant increases, the cargo weight limit decreases by that much.
GAW (Gross Axle Weight) is the total weight placed on each axle (front and rear) -
including vehicle curb weight and all payload.
GAWR (Gross Axle Weight Rating) is the maximum allowable weight that can be carried
by a single axle (front or rear). These numbers are shown on the Safety Compliance
Certification Label located on the driver's door frame or door pillar. The total load on
each axle must never exceed its GAWR.
GVW
GVW (Gross Vehicle Weight) is the Vehicle Curb Weightcargopassengers.
GVWR (Gross Vehicle Weight Rating) is the maximum allowable weight of the fully
loaded vehicle (including all options, equipment, passengers and cargo). The GVWR is
shown on the Safety Compliance Certification Label located on the driver's door
frame or door pillar. The GVW must never exceed the GVWR.

WARNING
Exceeding Axle Weight Rating Limits:Exceeding the Safety Certification Label axle weight rating limits is dangerous and
could result in death or serious injury as a result of substandard vehicle handling,
performance, engine, transmission and/or structural damage, serious damage to the
vehicle, or loss of control.
Always keep the vehicle within the axle weight rating limits.
Do not tow a trailer with this vehicle: Towing a trailer with this vehicle is dangerous because it has not been designed to
tow a trailer and doing so will affect the drive system which could result in vehicle

GCW
GCW (Gross Combination Weight)is the weight of the loaded vehicle (GVW).
GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle - including all cargo and passengers - that the vehicle can handle without risking
damage. The GCW must never exceed the GCWR.
WARNING
Exceeding GVWR or GAWR Specifications:
Exceeding the GVWR or the GAWR specified on the certification label is dangerous.
Exceeding any vehicle rating limitation could result in a serious accident, injury, or
damage to the vehicle.
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.
Never exceed the GVWR or the GAWR specified on the certification label.
