Chevrolet 2007 Avalanche, Owner'S Manual, Page: 171 / 628

Be sure the cargo is properly loaded.
•
If small heavy objects are placed on the roof,
cut a piece of 3/8 inch plywood to fit inside
the crossrails and siderails to spread the load.
If plywood is used, tie it to the siderail
supports.
•
Tie the load to the crossrails or the siderail
supports. Use the crossrails only to keep
the load from sliding. To move a crossrail, turn
the release knobs, on both sides of the rail,
counterclockwise to loosen it. Slide the
crossrail to the desired position balancing the
force side to side. Turn the release knobs,
on both sides of the rail, clockwise to tighten it
and try to slide the crossrail back and forth
slightly to be sure it is tight.
•
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 siderails or
siderail supports. Also tie the load to the
bumpers. Do not tie the load so tightly that the
crossrails or siderails are damaged.
•
After moving a crossrail, be sure it is securely
locked into the siderail.
Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the
CHMSL unit.
Rear Storage Area
Your vehicle is equipped with a rear
armrest/cupholder for the rear seat passengers.
To open it, pull up and then out on the tab, located
at the top center of the armrest, and pull the
armrest down.
