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 def oggers are on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the hybrid system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.

flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following
situations.
 No passengers are detected
in the rear seats
 The windshield defogger is
not operating
While operating, illuminates.
■Manually turning front seat
concentrated airflow mode
on/off
In front seat concentrated air-
flow mode, directing airflow to
the front seats only and to all seats can be switched via switch
operation. When the mode has
been switched manually, auto-
matic airflow control stops oper-
ating.
Press on the air conditioning
operation panel and switch the
airflow.

Indicator illuminated: Airflow
to the front seats only
 Indicator off: Airflow to the all
seats
■Operation of automatic airflow
control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the hybrid system is
started and at other times depend-
ing on the outside temperature.
●After the hybrid system is started,
if passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accura tely detect the
presence of passengers and auto-
matic airflow co ntrol will not oper-
ate.
■Operation of manual airflow
control
Even if the funct ion is manually
switched to directing airflow to only
the front seats, w hen a rear seat is
occupied, it may automatically direct
airflow to all seats.
■To return to automatic airflow
control
1 With the indicator off, turn the
power switch off.
2 After 60 minutes or more elapse,
