■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 m ay enter into
and accumulate in the air conditioning system. This may then ca use 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 t he blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.
■ Air conditioning filter
P. 626
■ Customization
Settings (e.g. A/C auto switching operation) can be changed. (C ustomizable
features: P. 739)
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 t hat 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 surfaces when the outside rea r 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.

■S-FLOW mode
In S-FLOW mode, priority for the airflow is given to the front seats,
reducing the airflow and air conditioning effect on the rear se ats.
When a passenger is not detected in the front passenger seat,
depending on the set temperature and ambient temperature, prior -
ity for the airflow will be given to the driver’s seat only.
However, air will always be blown from the side outlet of the front pas-
senger seat.
The following S-FLOW modes are available:
Automatic S-FLOW mode

vehicle by the opening and closing of a rear door. When a rear
passenger is determined to be in the vehicle, S-FLOW mode will
be automatically disabled.
