Chevrolet 2010 Corvette Convertible Owner's Manual page 310

Refer to your vehicle's Tire and Loading
Information label for specific information about
your vehicle's capacity weight and seating
positions. The combined weight of the driver,
passengers and cargo should never exceed your
vehicle's capacity weight.
A vehicle specific Certification label is attached
to the rear edge of the driver's door. It tells you
the gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating (GVWR).
5-32
The GVWR includes the weight of the vehicle, all
occupants, fuel and cargo. Never exceed the
GVWR for your vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or rear axle.
Do not load your vehicle with more weight than it
was designed to carry. See Steps for Determining
Correct Load Limit earlier in this section.
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do, parts
on the vehicle can break, and it can change
the way the vehicle handles. These could
cause you to lose control and crash.
Also, overloading can shorten the life of
the vehicle.
