Information
Using the system in the fresh air position
is recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging
of the windshield and side windows and
the air within the passenger
compartment will become stale.
In addition, prolonged use of the air
conditioning with the recirculated air

dry air in the passenger compartment.

conditioning or heating system on.
