■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions, etc. As a result, the following may occur.
●Immediately after is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is
on.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with under these condition, such as temperature setting and
inside temperature.
Also, outside air mode may be automatically switched to when the outside
temperature is low.
■When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on
●In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the “POWER”
switch is turned to ON mode.
●It is possible to switch to outside air mode at any time by pressing
.
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■Operation of the air conditioning 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 i m p r o v e a i r c o n d i t i o n i n g p e r f o r m a n c e , p e r f o r m t h e f o l l o w i n g o p e r a t i o n s :
●Adjust the fan speed
●Turn off Eco drive mode (→P. 2 4 7 )
●Customize the air conditioning control of Eco drive mode. (→P. 6 3 9 )
■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 r e d u c e p o t e n t i a l o d o r s f r o m o c c u r r i n g :
•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.

Improper maintenance could result in serious damage to the vehicle and
possible serious injury or death.
■Handling of the 12-volt battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by

PRIUS PHV_OM_OM47818U_(U)
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Yo u r v e h i c l e m a y n o t p a s s t h e I /
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■Yo u r v e h i c l e m a y n o t pa s s t h e I / M t e s t i n t h e f o l l o w i n g s i t u a -
tions:
●When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a tempo-
rary malfunction and your vehicle may not pass the I/M test.
■When the malfunction indicator lamp still remains on after
several driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■If your vehicle does not pass the I/M test
Contact your Toyota dealer to prepare the vehicle for re-testing.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (→P. 4 6 6 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

4-3. Do-it-yourself maintenance
PRIUS PHV_OM_OM47818U_(U)
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least
once a month.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire infla-
tion pressure that is even just a few pounds off can affect ride quality
and handling.
●Do not reduce tire inflation pressure after driving. It is normal for tire
inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.
