Certification Label
A vehicle specific Certification label is found on the
rear edge of the driver's door.
The label shows 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.
If the vehicle is going to carry a heavy load, spread it
out. Do not carry more than 167 lbs (76 kg) in the trunk.
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.
