Loading Your Vehicle
Two labels on your vehicle show how
much weight it may properly carry. The
Tire-Loading Information label found
on the inside of the trunk lid tells you
the proper size, speed rating and
recommended inflation pressures for
the tires on your vehicle. It also gives
you important information about the
number of people that can be in your
vehicle and the total weight that you
can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight of all occupants, cargo, and
all nonfactory-installed options.
The other label is the Certification label,
found on the rear edge of the driver’s
door. It tells you the gross weight
capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating).
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 you do have a heavy load, you
should spread it out. Don’t carry more
