Your Scion is equipped with several sophisticated computers that will rec\
ord
certain data, such as:• Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
• 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
Scion may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Scion will not disclose the recorded data to a third party except:
• 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- ment agency
• For research purposes where the data is not tied to a specific vehicle or vehicle owner

Characteristics of the EV (Electric Vehicle)
system
The illustration is an example for explanation purposes only and may
vary from the actual vehicle.Electric motor (traction motor)
Traction battery
Provides electricity to the electric motor.
12-volt battery
Provides electricity to various v ehicle systems such as the SRS air-
bags, headlights, wipers, etc.
Electric vehicles are considerab ly different from conventional
vehicle.
They use electricity charged in a traction battery, instead of fos-
sil fuels, to drive the electric motor. Since electric vehicles drive
using electricity, they do not emit any emissions such as CO2
(Carbon Dioxide) and NOx (Nitroge n Oxides). Electric vehicles
are environmentally friendly vehicles.

◆When braking (regenerative braking)
The electric motor (traction motor) charges the traction battery.
The driving range can be extended by actively using this regenera-
tive braking to store electricity in the traction battery.
◆Charging
The electric vehicle is driven using electricity, received from an
external power source, that is stored in the traction battery. Not only
public charging stations, but also household electrical outlets can
be used for charging. Procedures are different from refueling a con-
ventional vehicle. Theref ore, make sure to read the following thor-
oughly.
● Charging equipment ( P. 84)
● Power sources that can be used ( P. 88)
● How to charge your vehicle ( P. 181, 195)
● If charging cannot be done ( P. 377)
● Inspecting the charging cable ( P. 262)

742-1. Electric vehicle
Electric vehicles do not emit engine sounds. To warn pedestrians,
people riding bicycles or other peop le, and vehicles in the surrounding
area that the vehicle is approaching , a sound is intentionally produced
while driving. The pitch of the s ound adjusts according to vehicle
speed. When vehicle speed is approximately 16 mph (25 km/h) or
more, the warning system turns off.
The estimated driving range
based on the amount of remaining
battery charge can be displayed.
For details, refer to the “Navigation
System Owner’s Manual”.
Power consumpti on information
can be displayed on the screen.

■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
traction battery.
●The accelerator pedal is released while driving with the shift lever in D, S or
B.
● The brake pedal is depressed while driving with the shift lever in D, S or B.
If “REGENERATIVE BRAKING LIMITED” appears on the multi-information
display, refer to P. 347.
■ 12-volt battery recharging
The 12-volt battery is charged from the traction battery when the EV system
is operated or while the traction battery is being charged.
If the vehicle has not been used for a long time, the 12-volt battery may
become low due to self-discharge. If this occurs, follow the correct proce-
dures. ( P. 386)
■ When not using the vehicle for an extended period of time
P. 191
■ Charging the traction battery
Be sure to maintain the traction battery charge level suitable for your driving
needs.
If the traction battery fully discharges, the vehicle cannot be driven at all.
When the battery becomes low, charge it as soon as possible.
■ If the traction battery becomes low
●If the SOC (State of Charge) warning light flashes, the power used by the air
conditioning system will automatically be restricted and the traction battery’s
remaining charge will be distributed for driving the vehicle. If the traction bat-\
tery fully discharges, driving will not be possible. When the battery becomes
low, charge it as soon as possible.

762-1. Electric vehicle
●When the traction battery becomes low, the SOC (State of Charge) warning
light comes on or flashes and a following message will appear on the multi-
information display.
SOC
gauge Warning light
Warning message
Vehicle’s state
No effect on driving.
(However,
the vehicle cannot
drive long distances,
therefore charge the
battery as soon as
possible.)
• The remaining bat- tery charge is very
low, and continuous
driving will be diffi-
cult.
• To drive the vehicle
as long as possible,
the motor output is
restricted.
The battery power has
discharged while driv-
ing (the vehicle is
moving while the EV
system is down).
The vehicle cannot
start because the bat-
tery is completely dis-
charged.

■Driving Range
■ Sound and vibrations speci fic to an electric vehicle
Because an electric vehicle does not have the engine sound or vibrations that
a conventional vehicle has, the driver may not notice that the “READY” indi-
cator is illuminated and the vehicle can be driven. For safety reasons, always
shift the shift lever to P and apply the parking brake when the vehicle is
parked.
Before and after the EV system is started, the following sounds and vibrations
may occur.
However, these sounds and/or vibrations are not signs of malfunctions:
● The brake system operation sound heard from the front of the vehicle when
the driver’s door is opened.
● Motor sounds coming from the motor compartment.
● Electrical relay sounds may be heard from the motor compartment when the
EV system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emitted from the
traction battery in the following situations:
• When the EV system is started or stopped
• When charging starts or finishes
• When the vehicle is driven the first time after the traction battery has been
charged using quick charge
● Operating sounds or motor sounds that occur when the brake pedal is oper-
ated.
● Cooling fan operating sounds from the radiator and/or traction battery.
● The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).
An estimated possible driving range,
which is calculated from traction battery’s
remaining charge, the air conditioning
operating mode and so forth, is shown on
the multi-information display.
However, the actual possible driving
range significantly varies depending on
the driving manner, weather and usage of
electrical components.
Use the estimated possible driving range
as a reference only, and try to keep the
battery as charged as possible.

EV (Electric Vehicle) system precautions
The illustration is an example for explanation purposes only and may
vary from the actual vehicle.
Be careful of the high voltage components (about 300 V at maxi-
mum), such as the traction battery, power control unit, orange
colored high voltage cables, and electric motor, as well as high
temperature components such as the cooling radiator, which are
provided on the electric vehicle. For the high voltage compo-
nents, caution labels are provided on them. Read them when
they need to be handled.
