Air recirculation is used to:
– isolate the passenger compartment
from the external atmosphere (eg.:
driving in polluted areas, etc.);
– bring the passenger compartment to
the desired temperature more effec-
tively.
To return to the external air position,
push control D to the right.
Prolonged use of this position
can lead to condensation forming
on the side windows and wind-
screen and problems due to the
use of non-renewed air in the
passenger compartment.
It is therefore advisable to return to
normal operation (external air) by
moving control D to the right once
you are out of the polluted area.
