■Fogging up of the windows
● The windows will easily fog up when the humidity in the vehicle is high.
Turning (if equipped) on will dehumidify the air from the outlets and
defog the windshield effectively.

set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode

WARNING
■To prevent the windshield from fogging up
● Do not set to during cool air operation in extremely humid
weather. The difference between the temperature of the outside air and
that of the windshield can cause the outer surface of the windshield to fog
up, blocking your vision.
■ To prevent burns
● Vehicles with outside rear view mirror defoggers: Do not touch the rear
view mirror surfaces when the outsi de rear view mirror defoggers are on.
● Vehicles with windshield wiper de-icer: Do not touch the glass at lower part
of the windshield or the side of the front pillars when the windshield wiper
de-icer is on.
