Certification Label
Label Example
A vehicle specific Certification label is attached to
the center pillar (B-pillar), below the driver's
door latch. This label tells you the gross weight
capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). 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.

And, if you do have a heavy load, you should
spread it out. See "Steps for Determining Correct
Load Limit" earlier in this section.
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.
Notice: Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
