■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating, and are not a malfunction.
●The brake system operation sound heard from the front of the vehicle
when the driver’s door is opened.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind
the rear seat when the hybrid system starts or stops.
●Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when you press the
brake pedal or release the accelerator pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent. (→P. 4 5 )
●The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

When driving
■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (→P. 2 4 7 ) To i m p r o v e a i r
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■For the shift positions
●When the “POWER” switch is off, the shift position cannot be changed.
●When the “POWER” switch is in ON mode (the hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
However, immediately after turning the “POWER” switch to ON mode,
the shift position may not change to N.
●When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
●When the “READY” indicator is flashing, the shift position cannot be
changed from P to other position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.
●The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
●Situations where the shifting operation will be disabled:
•When an attempt is made to change the shift position from P to other
position by moving the shift lever without depressing the brake pedal.
•When an attempt is made to change the shift position from P or N to B
by moving the shift lever.
•When an attempt is made to change the shift position from P to another
position by moving the shift lever while the charging cable is connected
to the vehicle.

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.
(Customizable features →P. 6 3 9 )

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.
