•
: Distributes air through the floor vents, demister vents and rear
seat floor vents (if equipped).
4. A/C: Press to activate/deactivate air conditioning. Use with
recirculated air to improve cooling performance and efficiency. A/C
engages automatically in MAX A/C,
(defrost) and
(floor/defrost).
5. Recirculated air: Press to recirculate the air in the vehicle.
Recirculated air may reduce the amount of time needed to cool down the
interior of the vehicle (when used with A/C) and may also help reduce
undesired odors and dust/debris from reaching the interior of the vehicle.
This button engages automatically when MAX A/C is selected or can be
engaged manually in any airflow mode except
(defrost). This
button may turn off automatically in all airflow modes (except MAX A/C)
and when the ignition is cycled (if the A/C indicator light is not
illuminated ) in order to prevent window fogging. Even when this button
is not selected, air may still recirculate in some instances in order to
reduce vehicle warm-up time in cold conditions or to cool down time in
hot conditions. Note: You may notice changes in sound between
recirculated mode and other airflow modes.
6. MAX A/C: Distributes recirculated air through the instrument panel
vents and center console vents (if equipped) to cool the vehicle. This
re-cooling of the interior air is more economical and efficient.
Recirculated air may also help reduce undesirable odors and dust/debris
from entering the vehicle. Press the MAX A/C button again for normal
A/C operation.
7. Temperature control: Controls the temperature of the airflow in the
vehicle.
8. Fan speed adjustment: Controls the volume of air circulated in
the vehicle.
9. Power: Press to activate/deactivate the climate control system.
When the system is off, outside air is prevented from entering the
vehicle.
Operating tips
• To reduce fog build-up on the windshield during humid weather,
select (defrost) or (floor/defrost). Temperature and/or fan
speed can also be increased to improve clearing.
• To reduce humidity build-up inside the vehicle: do not drive with the
system off or with (recirculated air) engaged and A/C off.
