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

■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

■Scheduled maintenance of the
air intake vents is necessary
when
In some situations such as when the

heavy traffic or dusty areas, the air
intake vents may need to be
cleaned more regularly. For details,
refer to the “Owner’ s Warranty Infor-
mation Booklet” or “Owner’s Manual
Supplement”.
■Cleaning the air intake vent
●Dust in the air intake vent may
interfere with the cooling of the
hybrid battery (traction battery). If
charging/discharging of the hybrid
battery (traction battery) becomes
limited, the distance that the vehi-
cle can be driven using the electric
motor (traction motor) may be
reduced and the fuel economy
may be reduced.
Inspect and clean the air intake
vent periodically.
●Improper handling of the air intake
vent cover and filt er may result in
damage to them. If you have any
concerns about cleaning the filter,
contact your Toyota dealer.
■If “Maintenance Required for
Traction Battery Cooling Parts
See Owner’s Manual” is dis-
played on the multi-information
display
●If this warning message is dis-
played on the multi-information
display, remove the air intake vent
cover and clean the filter.
(  P.489)
●After cleaning the air intake vent,
start the hybrid system and check
that the warning message is no
longer shown.
It may take approximately 20 min-
utes after the hybrid system is
started until the warning message
disappears. If the warning mes-
sage does not disappear, have the
vehicle inspected by your Toyota
dealer.
