Vehicle data recordings

PRIUS PRIME_OM_OM47C17U_(U)
11
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-lik e 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 circu mstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a non-trivi al crash situ-
ation occurs; no data are recorded by the EDR under normal driv ing 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 routi nely acquired
during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access
to the vehicle or the EDR is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have the special e quipment, can
read the information if they have access to the vehicle or the EDR.
●Disclosure of the EDR data
Toyota will not disclose the data recorded in an EDR to a third party except
when:
• An agreement from the vehicle’s owner (or the lessee for a lea sed vehi-
cle) is obtained
• In response to an official request by the police, a court of l aw or a govern-
ment agency
• For use by Toyota in a lawsuit
However, if necessary, Toyota may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes witho ut disclosing
information about the specific vehicle or vehicle owner

2-1. Plug-in hybrid system
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the rech arging 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 posit ion in D or B.
■ EV driving range
●The EV driving range is displayed on the multi-information disp lay etc.
( P. 199, 215, 222, 239)
● The EV driving range changes in accordance with the charge status of the
hybrid battery (traction battery), the speed of the vehicle, et c.
● Even if there is enough charge remaining in the hybrid battery (traction bat-
tery), EV driving may be canceled and both gasoline engine and electric
motor are used depending on the situation. ( P. 87)
■ After EV mode has switched to HV mode due to low hybrid battery (trac-
tion battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range etc. will be displayed on the multi-
information display and EV mode will be automatically switched to.
If EV mode is not switched to even though EV driving range is b eing dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.
■ Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source. However, as the gasoline engine is used depending on the
situation even if in EV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refuelin g the vehicle.
Check the fuel amount and refill immediately when the fuel level becomes
low. ( P. 356)

■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In this event, charge the 12 -volt battery.
( P. 591)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction ba ttery) from
external power source or start the hybrid system at least once every 2 or 3
months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have pass ed since the “READY” indicator came
on, the power switch can be turned to off without any further action.)
● When the vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to cont rols, such
as the system checking, operating. When the charging cable is n ot needed,
immediately remove it from the vehicle.
■ Sounds and vibrations sp ecific to a hybrid vehicle
There may be no engine sound or vibration even though the vehic le is able to
move with the “READY” indicator is illuminated. For safety, app ly the parking
brake and make sure to shift the shift position to P when parke d.
The following sounds or vibrations may occur when the hybrid sy stem is
operating and are not a malfunction.
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emi tted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● 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 the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. ( P. 91)
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification syst em may be diffi-
cult for surrounding people to hear.
● In very noisy areas
● In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● 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 hy brid 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 bat tery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction ba ttery) is dam-
aged, the internal construction of the battery will prevent a l arge amount of
electrolyte from leaking out. However, any electrolyte that doe s leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.
● Do not bring burning or high-tem perature 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.
● If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. Th is may
cause a fire. ( P. 650)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits a t
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leav ing and avoid delays as much a s
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to mov e forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exc es-
sive electricity and fuel consumption.
◆Highway driving
● Control and maintain the vehicle at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to re lease
the accelerator and gently apply the brakes. A greater amount o f
electrical energy can be regenerated when slowing down.
● Electricity consumption will in crease significantly when drivin g at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is rec om-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

2-2. Charging
Before charging, always check the following items.
● The parking brake is applied.( P. 3 3 7 )
● The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interi or lights etc. are switched off.
If these light switches are turned ON, then these features will consume
electricity, and charging time will increase.
● The power switch is off. ( P. 3 2 4 )
Before charging, make sure that each part of the charging cable is in
good condition. ( P. 11 2 )
■Safety functions
●The hybrid system will not start while the charging cable is at tached to the
vehicle, even if the power switch is operated.
● If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving wi ll not be possi-
ble.
● When the charging cable is connected to the vehicle, the shift position can-
not be changed from P to another position.
■ During charging
The followings occur, however, it does not indicate a malfuncti on.
● The charging starting time may differ depending on the state of the vehicle.
● During charging, the sound of the fan may be heard from the cha rging
equipment cooling air intake vents. ( P. 135)
● During and after charging, the rear seat and its surrounding ar ea in which
the charging equipment is installed may get warm.
Confirm the following before charging
