4. Things you must know
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released while driving with the shift position in D
or B.
●The brake pedal is depressed while driving with the shift position in D or
B.
■Gasoline engine operation in EV mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range is being displayed, the gasoline
engine may operate automatically in the following circumstances (EV driving
will be returned to automatically after EV driving becomes possible again):
●When the heater etc. is in use.
●When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high
speeds, etc.
●When the temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32 °F (0 °C)
for a long period of time etc.
●When power is needed temporarily, for example when accelerating sud-
denly.
●When vehicle speed is more than approximately 62 mph (100 km/h).
●When the accelerator pedal is depressed firmly or the vehicle is on a hill
etc.
●When the outside temperature is low (less than 14 °F [-10 °C])
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.

Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Cruise control system
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

certain data, such as:
•Engine speed
•Electric motor speed (traction motor speed)
• Accelerator status
•Brake status
•Vehicle speed
•Shift position
•Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options
with which it is equipped. Furthermore, these computers do not record con-
versations, sounds or pictures.
●Data usage

• With the consent of the vehicle owner or with the consent of the lessee if
the vehicle is leased
•In response to an official request by the police, a court of law or a govern-

Event data recorder
This vehicle is equipped with an event data recorder (EDR). The main pur-
pose of an EDR is to record, in certain crash or near crash-like situations,
such as an air bag deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The EDR is designed
to record data related to vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
•How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fas-
tened;
•How far (if at all) the driver was depressing the accelerator and/or brake
pedal; and,
•How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a nontrivial crash situa-
tion occurs; no data are recorded by the EDR under normal driving condi-
tions and no personal data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforcement, could combine
the EDR data with the type of personally identifying data routinely acquired
during a crash investigation.

to the vehicle or the EDR is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have the special equipment, can
read the information if they have access to the vehicle or the EDR.

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released while driving with the shift position in D
or B.
●The brake pedal is depressed while driving with the shift position in D or
B.
■EV driving range
●The EV driving range is displayed on the energy monitor and the Hybrid
System Indicator. (→P. 5 8 , 2 6 8 )
●The EV driving range changes in accordance with the charge status of
the hybrid battery (traction battery), the speed of the vehicle, etc.
■After EV mode has switched to HV mode due to low hybrid battery
(traction battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range will be displayed on the multi-infor-
mation display and EV mode will be automatically switched to.
If EV mode is not switched to even though EV driving range is being dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.

■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).

CAUTION
■Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
●Stop the vehic le in a safe place to prevent subsequent accidents.
While depressing the brake pedal, apply the parking brake, shift the shift
position to P and turn the hybrid system off. Then, slowly release the brake
pedal.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
●Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic electrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
●If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off an acidic vapor. This vapor is an irritant to skin and eyes and
could cause acute poisoning if inhaled.
●Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
