Operating Tips; Air Outlets - GMC Hummer H3 2008 Owner's Handbook Manual

When activated automatically, the
recirculation feature cannot be
turned off manually.
If you try to activate or deactivate
the recirculation feature when it is
not available or when it has been
activated automatically, the indi-
cator light on the button will flash
to let you know that the function
will not operate.

Operating Tips

Before using the air conditioning
system, open the windows for a
few minutes to permit hot air to
escape. Close the windows when
using the air conditioning system.
For maximum cooling, activate
the recirculation mode.
Keep the bonnet and front air inlet
free of ice, snow, leaves or any
other obstruction.
Keep the area under the front seats
clear of objects to help air circulate
through the vehicle.
Adding equipment to the front of
your vehicle may keep the climate
control system from working
properly. Check with your dealer
before adding equipment to the
outside of your vehicle.

Angle the outlets up or down and
turn the thumb-wheel under the

as desired.
Opening and closing the louvres
also increases and decreases the
amount of airflow.
