The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging and
Defrosting” later in this section.
By positioning the right knob between two modes, a
combination of those two modes is selected.
The air conditioning compressor will be on unless the
outside temperature is close to freezing.
9 (Fan): Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob all the way counterclockwise to turn the
front system off.
: (Outside Air): Press this button to turn on the
outside air mode. When this mode is selected, air from
outside the vehicle will circulate throughout your
vehicle. An indicator light on the button comes on to
show that it is activated. The outside air mode can be
used with all modes, but it cannot be used with the
recirculation mode. Pressing this button again will cancel
the recirculation mode.
? (Recirculation): Press this button to turn on the
recirculation mode. When the button is pressed, an
indicator light will come on.
This mode keeps outside air from entering the vehicle. It
can be used to reduce outside air and prevent odors
from entering the vehicle. Recirculation may also
help cool the air inside your vehicle more quickly once
the temperature inside the vehicle is less than the
outside temperature.
The recirculation mode cannot be used with floor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator light
will flash three times and turn off. The air conditioning
compressor will also come on when this mode is
activated. While in recirculation mode the windows may
fog when the weather is cold and damp. To clear the
fog, select either the defog or defrost mode and increase
the fan speed. Recirculation mode can be turned off
by pressing the button again, or turning off the engine.
Temperature Control: Rotate the thumbwheels up
or down to increase or decrease the temperature on the
driver’s side or the passenger side of the vehicle for
the dual zone system, if equipped. Otherwise, turn the
center knob clockwise or counterclockwise to increase or
decrease the temperature inside the vehicle.
# (Air Conditioning): Press this button on the left
knob to turn the air conditioning system on or off. When
A/C is pressed, an indicator light comes on to show
that the air conditioning has been activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
