Loading Your Vehicle
Two labels on your vehicle show how
much weight
it may properly carry. The
Tire-Loading Information label found
on
the driver’s door lock pillar 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.
