climate settings HUMMER H3 2006 Owners Manual

9(Off):Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airow from
occurring.
The right knob on the control panel is used to direct the
airow inside your vehicle. Turn the knob to select
one of the following modes:
@(Recirculation):Press the center knob on the
control panel to recirculate air inside the vehicle
and prevent outside air from coming in. It can be used
to prevent outside odors from entering your vehicle
and cool the air inside your vehicle more quickly. Press
this button to turn the recirculation mode on or off.
An indicator light on the button will come on to let you
know the recirculation mode is activated. This is normal.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available, and the light will
not come on, while in oor, oor/defog and defrost
mode. If recirculation is selected in these modes, the
indicator will ash three times indicating it is not
available in that mode.
H(Vent):Turn the right knob on the control panel to
this mode to direct air to the instrument panel outlets.
\(Bi-Level):Turn the right knob on the control panel
to this mode to direct air to the instrument panel outlets,
and the remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control panel to
this mode to direct air to the oor outlets, side window
outlets, and defroster. Recirculation is not available
in this mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or frost
from the windshield more quickly. For best results, clear
all snow and ice from the windshield before defrosting.
/(Floor/Defog):Turn the right knob on the control
panel to this mode to direct the air to the windshield, the
side window outlets, and to the oor outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature is
near freezing or below. Recirculation is not available
in this mode.
