Outlet Adjustment - GMC 2007 Yukon Denali Owner's Manual

If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed.
Notice: Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.

Outlet Adjustment

Use the air outlets located in the center and on
the side of the instrument panel to direct the
airflow.
Operation Tips
•
Keep the hood and front air inlets free of ice,
snow, or any other obstruction, such as
leaves. The heater and defroster will work
better, reducing the chance of fogging
the inside of your windows.
•
When you enter a vehicle in cold weather, set
the fan speed to maximum airflow for a few
moments before driving. This helps clear
the intake ducts of snow and moisture, and
reduces the chance of fogging the inside
of your windows.
•
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
•
Adding outside equipment to the front of the
vehicle, such as hood-air deflectors, may
affect the performance of the heating and
air conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
