Certification/Tire Label
A vehicle specific Certification/Tire label is
attached to the rear edge of the driver's door.
The label shows the gross weight capacity of your
vehicle. This is called the Gross Vehicle Weight
Rating (GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel, and cargo.

The Certification/Tire label also tells you the
maximum weights for the front and rear axles,
called the Gross Axle Weight Rating (GAWR). To
find out the actual loads on your front and rear
axles, you need to go to a weigh station and weigh
your vehicle. Your dealer can help you with this.
Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle or the
GAWR for either the front or rear axle.
CAUTION:
{
Do not load your 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 your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
