Climate controls
Operating tips
• In humid weather conditions, place the climate control system in
or rear defrost before driving. This will reduce fogging on your
windshield. Once the windshield has been cleared, operate the climate
control system as desired.
• To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF
position or .
• To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
• Under normal weather conditions, your vehicle's climate control
system should be left in any position other than OFF or
the vehicle is parked. This allows the vehicle to "breathe" through the
outside air inlet duct.
• Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
• If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been "aired out", operate the climate
control system as desired.
• Don't put objects under the front seat that will interfere with the
airflow to the rear seats.
• Remove any snow, ice or leaves from the air intake area at the area
(at the bottom of the windshield and underneath the hood).
• Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Avoid placing small objects on top of the instrument panel. These
objects may fall down into the defroster outlets and block airflow, in
addition to damaging the climate control system.
