IS300h_EE(OM53B95E)
Air conditioning odors
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.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the 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. 470
Customization
Settings (e.g. A/C Auto switch operation) can be changed.
(Customizable features P. 582)
CAUTION
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 wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on.
NOTICE
To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
