To prevent damage or loss of cargo as you're leaving,
check now and then to make sure the luggage and cargo
are still securely fastened.
Be sure the cargo is properly loaded.
D
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 Yukon XL Denali models). If you
need to, 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.
D
Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from sliding.
To move the crossrails, pull out on the latch release
handle at each end. Slide the crossrail to the desired
position balancing the force side to side. Push the
release handle back into the latched position and
slide the crossrail back and forth slightly to be
sure the latch snaps securely into place.
D
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.
D
For the purpose of wind noise reduction, locate
the front crossrail approximately 18 to 24 inches
(46 cm to 58 cm) rearward of the front supports.
D
After moving a crossrail, be sure it is securely locked
into the siderail.
Your vehicle has a Center High
(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.
