2-1. Plug-in hybrid system
NOTICE
■Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents a s this may
cause a short circuit and damage the hybrid battery (traction b attery).
● Do not carry large amounts of water such as water cooler bottle s in the
vehicle. If water spills onto the hybrid battery (traction batt ery), the battery
may be damaged. Have the vehicle inspected by your Toyota deale r.
● A filter is installed to the air intake vent. When the filter r emains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 568.
■ Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal. (20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel
a total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-mon th period), as
this may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of ti me and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.

Interior features
■Ventilation and air conditioning odors
●To let the fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, the start timing of t he blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.
■ Air conditioning filter
P. 626
■ Customization
Settings (e.g. A/C auto switching operation) can be changed. (C ustomizable
features: P. 739)
WARNING
■ To prevent the windshield from fogging up
● Do not use
during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and t hat of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

Interior features
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic , set
to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling ope ration, setting
the recirculated air mode will also cool the vehicle interior e ffectively.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helpin g to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditionin g eco
mode
● In the air conditioning eco mode, the air conditioning system i s controlled as
follows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict h eating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Turn off the air conditioning eco mode
● When the driving mode is set to Eco driving mode, the air condi tioning eco
mode will be turned on automatically. Even in this case, the ai r conditioning
eco mode can be turned off by selecting . ( P. 415)
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is
selected.
