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
recirculation control on or the system turned off.
• 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.”
• 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.
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C in
the MAX A/C position, reduce blower fan speed from the highest setting
and put the vehicle’s transmission into the PARK gear position to
continue to receive cool air from your A/C system.
