Luggage Carrier (If Equipped)
If you have the optional luggage carrier, you can load
things on top of your vehicle.
The luggage carrier has slats and side rails attached to
the roof, and crossrails which can be moved toward the
front or the rear in the side rails
to help secure cargo. Tie
the load to the side rails or side rail supports.
NOTICE:
Loading cargo that weighs more than 200 lbs.
(90.6 kg) on the luggage carrier may damage
your vehicle. When
you carry large things, never
let them hang over the rear or the sides
of your
vehicle. Load your cargo
so that it rests on the
slats and does not scratch or damage the vehicle.
Put the cargo against the side rails and fasten
it
securely to the luggage carrier.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see “Loading Your Vehicle”
in
the Index. To
prevent damage or loss of cargo as you’re driving,
check now and then to make sure the luggage carrier and
cargo are still securely fastened.
Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof, place
the load in the area over the rear wheels (behind
the
rear side door on Suburbans). If you need to, cut a
piece of 3/8 inch plywood to fit inside the crossrails
and side rails to spread the load, If plywood is used,
tie it to the side rail supports.
Tie the load to the crossrails or the side rail supports.
Use the crossrails only to keep the load from sliding.
0 If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the side rails or side rail supports. Also
tie the load to the bumpers. Do not tie the load
so
tightly that the crossrails or side rails are damaged.
0 After moving the crossrails, be sure to tighten all the
slider screws.
For the purpose of wind noise reduction, locate
the front crossrail approximately
18-24 inches
(46 cm to 58 cm) rearward of the front supports.

Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance and
service work done. Check to make sure all underbody
shields
(if so equipped) are properly attached. Be sure
you read all the information about your
four-wheel-drive vehicle in this manual.
Is there enough
fuel? Is the spare tire fully inflated? Are the fluid levels
up where they should be? What are the local laws that
apply
to off-roading where you’ll be driving? If you
don’t know, you should check with law enforcement
people in the area. Will you be on someone’s private
land? If
so, be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
0 Be sure the load is secured properly, so driving on
the off-road terrain doesn’t toss things around.
0
0
0
Cargo on the load floor 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 floor can be
tossed about when driving over rough terrain.
You or your passengers
can be struck by flying
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.
You’ll find other important information in this manual.
See “Vehicle Loading,” “Luggage Carrier” and “Tires”
in the Index.
