3904-6. Driving tips
Owners Manual_USA_M0C031_en
overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-
sume fuel. Also, fuel consump-
tion can be improved by
avoiding overuse of the heater.Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.

outside rear view mirrors.
Press the rear window and out-
side rear view mirror defoggers
switch.
The defoggers will automatically
turn off after 15 minutes.
When the rear window and outside
rear view mirror defoggers switch is
on, the indicator illuminates on the
rear window and ou tside rear view
mirror defoggers switch.
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally.
This may also reduce fuel con-
sumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
It is possible to switch to outside air
mode at any time by pressing the
outside air mode switch.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning the cooling and
dehumidification function on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn the cooling and dehu-
midification function off, the win-
dows may fog up more easily.
●The windows may fog up if the
recirculated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake mode be set to outside air mode and
the fan speed to a
ny setting except
off.
■Outside/recirculated air mode
●Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■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 suppr ess 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.

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,
turn the power switch to ON.

Maintenance and care
1 Insert the tab of the cover as
shown in the illustration.
2 Push the cover to engage the
2 claws.
■Scheduled maintenance of the
air intake vents is necessary
when
In some situations such as when the
vehicle is used frequently or in
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.481)
●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.
WARNING
■When cleaning the air intake
vent
●Do not use water or other liq-
uids to clean the air intake vent.
If water is applied to the hybrid
battery (traction battery) or
other components, a malfunc-
tion or fire may occur.
●Before cleaning
the air intake
vent, make sure to turn the
power switch off to stop the
hybrid system.
■When removing the air intake
vent cover
Do not touch the service plug
located near the air intake vent.
