GMC 1995 Jimmy Owner's Manual page 132

Use GM accessory racks that are compatible with your luggage carrier for
transporting sports equipment. These are available through your GM dealer.
Remove the center
rubber strips in the
cross rails and attach
the GM accessory
rack to the nut plates
provided through the
center slots (four per
cross rail).
rhe tap plates can be moved to accommodate various positioning by sliding
them inside the cross rail to the desired locations before mounting the
accessory rack.
You can adjust the cross rails to handle different size loads. Just loosen the
slider knobs at each end of the cross rail and move them where you want
them. Make sure both sides of the cross rail are even, then tighten the slider
knobs.
Be sure the cargo is properly loaded.
Carrying small, heavy loads
on
the roof is not recommended.
Tie the load to the moveable tie down, (two per each side of the side
rails). Use the cross rails only to keep the load from sliding.

If you need to carry long items, move the cross rails as far apart as
possible. Tie the load to the moveable tie downs provided in the side
rails. Also tie the load to the bumpers. Do not tie the load so tightly that
the cross rails or side rails are damaged.
NOTICE:
Loading cargo that weighs more than 200 pounds (91 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. Put the main weight as far forward as you can.
