CAUTION
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.
Hybrid battery (traction battery)
Never resell, hand over or modify the hybrid battery (traction battery). To pre-
vent accidents, hybrid batteries (traction batteries) that have been removed
from a disposed vehicle are collected through any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional. Do not dis-
pose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
• The hybrid battery (traction battery) may be illegally disposed of or
dumped, and someone may touch a high voltage part, resulting in an
electric shock.
• The hybrid battery (traction battery) is intended to be used exclusively
with your hybrid vehicle. If the hybrid battery (traction battery) is used
outside of your vehicle or modified in any way, accidents such as electric
shock, heat generation, smoke generation, an explosion and electrolyte
leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware
of these dangers.

CAUTION
Disposal of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery (traction battery) hav-
ing been removed, there is a danger of serious electric shock if high voltage
parts, cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery (traction battery) must be disposed
of by any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional or a qualified service shop. If the hybrid battery (trac-
tion battery) is not disposed of properly, it may cause electric shock that can
result in death or serious injury.
Your vehicle contains batteries and/or accumulators. Do not discard
them into the environment but cooperate with separate collection
(Directive 2006/66/EC).

When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During
start off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine
is stopped
* and the electric motor (traction motor) is used.
When shift position is in N, the hybrid battery (traction battery)
will not be charged. Thus, shift to P when the vehicle is stopped.
In addition, when driving in heavy traffic, use D or B.
*: However, when the hybrid battery (traction battery) need to be
charged or while the engine is being warmed up, the gasoline
engine may not stop automatically. (P. 40)
During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as
necessary.
When accelerating sharply
When the accelerator pedal is depressed heavily, the power of
the hybrid battery (traction battery) is added to that of the gaso-
line engine via the electric motor (traction motor).
When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery
(traction battery).

40 1-1. Hybrid system
PRIUS +_OM_OM47821E_(EE)
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.
Hybrid System Indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions
*:
During gasoline engine warm-up
When the temperature of the hybrid battery (traction battery) is high or
low
During hybrid battery (traction battery) charging
When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
Hybrid System Indicator represents the
hybrid system power output and regener-
ative charging. (
P. 243)

Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the
battery does not need to be charged from an outside source. However, if
the vehicle is left parked for a long time the hybrid battery (traction bat-
tery) will slowly discharge. For this reason, be sure to drive the vehicle at
least once every few months for at least 30 minutes or 16 km (10 miles).
If the hybrid battery (traction battery) becomes fully discharged and you
are unable to jump-start the vehicle with the 12-volt battery, contact any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. Always shift the shift position in P when the vehicle is stopped.
When driving in heavy traffic, operate the vehicle with the shift position in
D or B to avoid discharging the hybrid battery (traction battery).
Charging the 12-volt battery
P. 525
After the 12-volt battery has discharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

PRIUS +_OM_OM47821E_(EE)
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) 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 the brake pedal
is depressed and accelerator is loosened.
Other sounds, such as motors and mechanical noises, may be heard
from the brake system when the brake pedal is depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vent. (
P. 44)
The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).
Maintenance, repair, recycling, and disposal
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
