PRIUS PHV_OM_OM47856U_(U)
■Window defogger feature
●Recirculated air mode may automatically switch to outside air mode in
situations where the windows need to be defogged.
●When the outside air temperature is low, it may take a while for the con-
densation to clear from the windshield.
●When is turned ON, the gasoline engine may operate depending
on driving conditions. After that, even if is turned OFF, the fan
does not stop and a state in which it is easy for the gasoline engine to
operate continues. After defogging the windows, press as neces-
sary to turn off the fan.
■When is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the temperature setting.
■Micro dust and pollen filter
●In order to prevent the windows from fogging up when the outside air is
cold, the following may occur.
•Outside air mode does not switch to recirculated air mode.
•The air conditioning system operates automatically.
•The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
●Condensation may appear on the windows if this mode is used in abnor-
mally high levels of humidity.
●Pollen will be collected by the filter even when micro dust and pollen filter
mode is OFF.
■Maintenance of the air conditioning filter
The air conditioning filter must be cleaned or changed regularly to maintain
air conditioning efficiency according to the maintenance schedule. In dusty
areas or areas with heavy traffic flow, early replacement may be required.
(For scheduled maintenance information, refer to the “Owner’s Manual Sup-
plement/ Scheduled Maintenance Guide”.)
When inspecting, cleaning and replacing the air conditioning filter, contact
your Toyota dealer.

■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 9 )
●Customize the air conditioning control of Eco drive mode. (→P. 6 4 3 )
■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.

Safety information for Safety Connect
Important! Read this information before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wire-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
●ANSI (American National Standards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scientific literature. Over 120 scientists,
engineers, and physicians from universities, and government
health agencies and industries reviewed the available body of
research to develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

●Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■While charging
Do not wash the vehicle.
Doing so may cause the electrical components to malfunction or catch fire
and also you may get an electric shock that may result in death or serious
injury.
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
