WARNING
■To prevent the windshield from fogging up
Do not set the air outlet selector dial to during cool air operation in
extremely humid weather. The differ ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
■ To prevent burns (vehicles with outside rear view mirror defoggers)
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning syst em on longer than necessary when the

YARIS_F_OM_Europe_OM52A54E■Ventilation and air conditioning odors
●To let 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.
●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 AUTO mode.
■Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with a Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the auto-
matic air conditioning cooling, heating and dehumidification functions turn off
and the fan speed is decreased according to the outside temperature etc. or
air blowing stops. To stop the air conditioning system from turning off, press
the Stop & Start cancel switch and refrain from using the Stop & Start system.
■An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.
