Eco drive mode, the Eco air condi-

tioning mode will be turned on

automatically. Even in this case,

the Eco air conditioning mode can

be turned off by selecting the Eco

air conditioning mode switch.

Ventilation and air conditioning

odors

●

To let fresh air in, set the air condi-

tioning 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, the air flow mode

may change to blow air to the feet

or air may stop blowing for a short

period of time immediately after

the air conditioning system is

started in automatic mode.

●

When parking, the system auto-

matically switches to outside air

mode to encourage better air cir-

culation throughout the vehicle,

helping to reduce odors that occur

when starting the vehicle.

WARNING

■

To prevent the windshield

from fogging up

Do not use the windshield defog-

ger switch during cool air opera-

tion in extremely humid weather.

The difference between the tem-

perature of the outside air and

that of the windshield can cause

the outer surface of the wind-

shield to fog up, blocking your

vision.

■

When the outside rear view

mirror defoggers are operat-

ing

Do not touch the rear view mirror

surfaces when the outside rear

view mirror defoggers are on.

NOTICE

■

To prevent 12-volt battery dis-

charge

Do not leave the air conditioning

system on longer than necessary

when the fuel cell system is off.

■

Humidity sensor (Vehicles

with Toyota Teammate

Advanced Drive)

In order to detect fog on the wind-

shield, a sensor which monitors

the temperature of the windshield,

the surround humidity, etc. is

installed.

Follow these points to avoid dam-

aging the sensor:

●

Do not disassemble the sensor

●

Do not spray glass cleaner on

the sensor or subject it to strong

impacts

●

Do not stick anything on the

sensor

control: When the front passen-
ger seat is not occupied, airflow
may switch to only the driver’s
seat.
Unnecessary air conditioning is
suppressed, contributing to
increased fuel efficiency.

Operation of automatic airflow

control

●

In order to maintain a comfortable

interior, airflow may be directed to

seats without passengers immedi-

ately after the fuel cell system is

started and at other times depend-

ing on the outside temperature.

●

After the fuel cell system is

started, if passengers move

around inside or enter/exit the

vehicle, the system cannot accu-

rately detect the presence of pas-

sengers and automatic airflow

control will not operate.

■

Operation of manual airflow

switched to directing airflow to only

the front seats, when a rear seat is

occupied, it may automatically direct

airflow to all seats.
