WARNING
- Recirculated
air
Continuous use of the climate
control system in the recirculat-
ed air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.
WARNING
- Reduced visi-
bility
Continued climate control sys-
tem operation in the recirculat-
ed air position may allow
humidity to increase inside
vehicle which may fog the glass
and obscure visibility.
It should be noted that prolonged
operation of the heating in recirculat-
ed air position will cause fogging of
the windshield and side windows and
the air within the passenger com-
partment will become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected, will result in exces-
sively dry air in the passenger com-
partment.
