5.
Recirculated air (if equipped):
Press to activate/deactivate air
recirculation in the vehicle. Recirculated air may reduce the amount of
time needed to cool down the interior of the vehicle and may also help
reduce undesired odors from reaching the interior of the vehicle.
Recirculated air engages automatically when MAX A/C is selected or can
be engaged manually in any airflow mode except
(defrost). When
the ignition switch is turned off and back on, the climate system will
return to the recirculated air mode only if the A/C button LED is
illuminated and the air distribution selection is either
(panel)
or
(panel/floor).
6.
MAX A/C (if equipped):
Distributes recirculated air through the
instrument panel vents to cool the vehicle. This re-cooling of the interior
air is more economical and efficient than normal A/C mode. Recirculated
air may also help reduce undesirable odors 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.
•
Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•
Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•
To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out.”
•
A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
