Loading Your Vehicle
It is very important to know how much weight
your vehicle can carry. This weight is called the
vehicle capacity weight and includes the weight of
all occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how
much weight it was designed to carry, the
Tire and Loading Information label and the
Certification/Tire label.
{
CAUTION:
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 your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of the vehicle.
Tire and Loading Information Label
A vehicle specific Tire and Loading Information
label is attached to the center pillar (B-pillar).
With the driver’s door open, you will find the
label attached below the door lock post (striker).
The tire and loading information label shows
the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B)
in kilograms and pounds.
