Certification Label
Label Example
A vehicle specific certification label is attached to the
center pillar, near 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.
4-32
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.
If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
