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.

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.

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.
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.

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.

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.

3-10 Ventilation System
Your vehicle has air outlets
in the center and on the
sides of the instrument
panel. There are also two
outlets located on the back
of the center console for the
rear seat passengers.
You can move the outlets from side
-to-side and the
louvers up and down to direct the flow of air. The
driver's and passenger's side outlets can be closed. The
two outlets, located on the rear of the center console, can
also be closed. Turn the thumbwheel to the left to shut
off air flow or to the right to allow air flow. When you
close an outlet, it will increase the flow of air coming
out of any outlets that are open. The center outlet,
located on the instrument panel, does not completely
shut off airflow.For mild outside temperatures when little heating or
cooling is needed, use outside air to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.
Your vehicle's ventilation system supplies outside air
to the inside of your vehicle when it is moving. With
the side windows closed, air will flow into the front air
inlet grilles, through the vehicle, and out the air
exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation button pushed in. For more information on
the recirculation button, see ªAir Conditioningº earlier
in this section.
