Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■ Operation of the air conditio ning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode ( P. 206)
● Customize the air conditioning control of Eco drive mode. ( P. 596)
■ When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Air conditioning odors
●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 automatic
mode.
■ Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
(Customizable features P. 596)

■Operating conditions
The Solar Ventilation System may not operate under the following circum-
stances due to a lack of power from the solar panel:
●Low amount of sunlight
● Ever when a part of the solar panel is cast by a shadow.
● Ever when a part of the solar panel is covered by fallen leaves or dirt.
● The solar panel is not at a high temperature.
■ Before using the Solar Ventilation System
Remove dirt or fallen leaves from the solar panel in order to ensure sufficient
electrical output.
■ Efficient use of the So lar Ventilation System
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. ( P. 346)
■ When using the Sola r Ventilation System
● Make sure that the “POWER” switch is in ON mode when turning the
ventilation switch on. If the ventilation switch is turned on while the
“POWER” switch is OFF, the air mode and the status of the air vents will
remain unchanged.
● If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off.
Dirty air and exhaust fumes from other vehicles may be drawn from out-
side. Also, use in winter may cause heated interior air to leave the vehi-
cle, thus leading to a drop in temperature.
■ Sounds when using the Solar Ventilation System
If the amount of sunlight is insufficient, you may hear a sound coming from
the air conditioning system. This is the sound of a control function to pre-
serve the fan and does not indicate a malfunction.

PRIUS_OM_OM47857U_DVD_(U)
Warning messageDetailsCorrection procedure
(If equipped) • Indicates that the pre-collision
system is not currently func-
tional because the grille or the
sensor is dirty.
• This message also appears when the pre-collision system
is not functional due to over-
heating. • Check the grille
and the sensor and
clean them if they
are dirty.
• In case of over- heating, the system
will become func-
tional once the sys-
tem cools down.
(Flashes)
(If equipped) Indicates that the radar cruise
control sensor is dirty or cov-
ered with ice.
Clean the sensor.
(Flashes)
(If equipped) Indicates that the radar cruise
control system is unable to
judge vehicle-to-vehicle dis-
tance.
If the windshield
wipers are on, turn
them off or set
them to either the
intermittent or the
slow mode.

Vehicle specifications

■
Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can caus e heat buildup and possible tire fail-
ure.
