Luggage Carrier
If you have a luggage carrier. you can load things on top of your vehicle.
The luggage carrier has slats and side rails attached to the roof, and cross
rails which can be moved fore and aft in the side rails to help secure cargo.
Tie the load to the side rails or side rail supports. Use the cross rails mostly
for fore and aft stops.
NOTICE:
Loading cargo that weighs more than 200 pounds (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
a s
you're driving, check now and then to
make sure the luggage carrier and cargo are
still
securely fdstened.
Be sure the cargo is properly loaded.
If small heavy ob-jects 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 cross rails and
side rails to spread the load. I f plywood is used, tie
it
to the side rail
supports.

Tie the load to the cross rails or the side

rails only to keep the load from sliding.

If you need
t o
carry long items. move the cross rails as Fa- apart as they
will go. Tie the load to the cross rails and the side rails or side rail
supports. Also tie the load to the bumpers. Do not tie the load so tightly
that the cross rails or side rails are damaged.
After moving the cross rails, be sure to tighten all the slider screws.
