WARNING: (Continued)
There are some important things to remember about
how to load the vehicle.
See Loading the Vehicle on page 5 40 and Tires on
page 6 60 for other important information.
(Continued)
Heavy loads on the roof raise the vehicle's
center of gravity, making it more likely to roll
over. You can be seriously or fatally injured if
the vehicle rolls over. Put heavy loads inside
the cargo area, not on the roof. Keep cargo in
the cargo area as far forward and low as
possible.
The heaviest things should be on the floor, forward
of the rear axle. Put heavier items as far forward
as possible.
Be sure the load is properly secured, so things are
not tossed around.
