Ventilation and air conditioning odors
●To let the fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, the start timing of the blower may
be delayed for a short period of time i mmediately after the air conditioning
system is started in automatic mode.
■ Air conditioning filter
→P. 620
■ Customization
Settings (e.g. A/C auto switching operation) can be changed. (Customizable
features: →P. 732)
WARNING
■To prevent the windshield from fogging up
● Do not use
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, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surf aces when the outside rear view mirror
defoggers are on.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
