Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the cargo
properly.
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.There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load oor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain does not toss things around.
You will nd other important information in this manual.

Q:What is total vehicle reserve capacity?
A:This is the difference between your GVWR and the
weight of your vehicle with full fuel and passengers.
It is the amount of weight you can add to your
vehicle before reaching your GVWR. Keep in mind
that reserve capacity numbers are intended as
a guide when selecting the amount of equipment
or cargo your vehicle can carry. If you are unsure of
your vehicle’s front, rear, or total weight, go to a
weigh station and weigh your vehicle. Your dealer
can also help you with this.
The total vehicle reserve capacity for your vehicle
can be found in the lower right corner of the
Certication/Tire label as shown previously.
See your dealer for additional advice and information
about using a snow plow on your vehicle. Also,
seeLoading Your Vehicle on page 4-48.
