Operating tips
• In humid weather, select
before driving. This will reduce fogging
on your windshield. After a few minutes, select any desired position.
• To reduce humidity buildup inside the vehicle, don’t drive with the
climate control system in the OFF position.
• Don’t put objects under the front seat that will interfere with the
airflow to the rear seats (if equipped).
• Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under
the hood).
• Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Also, avoid placing small objects on top of your instrument panel.
These objects can fall down into the defroster outlets and block
airflow and possibly damage your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or a sudden stop.
