Recirculated air: Press to activate/deactivate air recirculation
in the vehicle cabin. Recirculated air may reduce the amount of time to
cool down the interior of the vehicle and may also help reduce undesired

engaged manually in any airflow selection except
. Recirculated air
may turn off automatically in all airflow selections.
Operating tips
• To reduce fog build-up on the windshield during humid weather, place
the air flow selector in the
position.
• To reduce humidity build-up inside the vehicle: do not drive with the
system off or with recirculated air
engaged.
• Under normal weather conditions, do not leave the air flow selector in
A/C and recirculated air
or with the system off when the
vehicle is parked. This allows the vehicle to “breathe” using the
outside air inlet vents.
• 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.”
