QHybrid battery (traction battery) charge mode
OThe following may occur to protect the system, etc.• Cannot switch to hybrid battery (trac-
tion battery) charge mode or cannot cancel it• Gasoline engine does not start or
stops even after switching to hybrid battery (traction battery) charge mode
OIf a load to the system is large, such as when the power consumption of the air conditioning system is large or
when the temperature of the engine coolant is high, it may take longer time than usual to charge using the hybrid
battery (traction battery) charge mode, or charging to the hybrid bat-tery (traction battery) may not be per-
formed.
QWhen in EV mode
In EV mode, EV driving (driving
using only the electric motor)* is
possible. However, depending on
the situation, EV driving may be
canceled and both gasoline engine
and electric motor are used
( P.90). Also, if a little electricity is
remaining in the hybrid battery
(traction battery), HV mode is auto-
matically selected. To drive in EV
mode long, observe the followings.
 Avoid sudden acceleration and
sudden deceleration, and be
sure to drive smoothly.

hybrid battery (traction battery)
WARNING
QWhen using the hybrid battery (traction battery) charge mode
Observe the following precautions
when using the hybrid battery (trac- tion battery) charge mode while park-ing.
Failure to do so may lead to death or serious health hazard, as the gasoline engine operates when in the hybrid
battery (traction battery) charge mode.
ODo not stop the vehicle near flam-
mable materials.
ODo not use the hybrid battery (trac-
tion battery) charge mode in a closed area where ventilation is insufficient, such as in a garage or
area with snow buildup.
Control when driving in

charge will deplete quickly. Also,
EV driving may be canceled by
rapid acceleration or vehicle
speed.
Restrain your speed as much as
possible. The distance that can
be driven in EV mode will reduce
considerably at high speeds.
*: The EV driving range can be checked
using the multi-information display.
(P.179)
QWhen in AUTO EV/HV mode
Only the electric motor is used for
EV driving
* during normal driving,
but when the accelerator pedal is
strongly depressed, the gasoline
engine starts. (P.90)
Also, when the hybrid battery (trac-
tion battery) level is low, the mode
switches to HV mode automatically
the same as in EV mode.
AUTO EV/HV mode is suitable for
driving conditions when more
power is required, such as for driv-
ing uphill or accelerating suddenly.
However, because the gasoline
engine will start more easily, it is
recommended to drive in EV mode
usually.
*: The EV driving range can be checked
using the multi-information display.
(P.179)
QWhen in HV mode
The vehicle can be used in the
same way as a standard Plug in
Hybrid Electric Vehicle.
In HV mode, controls are primarily carried out as follows in accor-
dance with the driving conditions.
The gasoline engine stops
* when
the vehicle is stopped.
During start off, the electric
motor (traction motor) drives the
vehicle.
During normal driving, the gaso-
line engine and electric motor
(traction motor) are controlled
effectively, and the vehicle is
driven with optimum fuel effi-
ciency. Also, when necessary,
the electric motor (traction
motor) operates as an electrical
generator to charge the hybrid
battery (traction battery).
When the accelerator pedal is
depressed heavily, drive force
from both the gasoline engine
and the electric motor (traction
motor) is used to accelerate.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine
is warming up, etc., the gasoline
engine will not automatically stop.
(P.91)
QWhen braking (regenerative
braking)
The electric motor (traction motor)
charges the hybrid battery (traction
battery).
The EV driving range can be
extended by actively using this
regenerative braking to store elec-
tricity in the hybrid battery (traction
battery).

902-1. Plug-in hybrid system
Moreover, as fuel consumption is
also reduced when in HV mode, the
regenerative braking system can be
used effectively.
QRegenerative 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).
OThe accelerator pedal is released
while driving with the shift lever in D or
S.
OThe brake pedal is depressed while
driving with the shift lever in D or S.
QEV driving range
OThe EV driving range is displayed on
the multi-information display.
(P.179)
OThe EV driving range changes in
accordance with the charge status of
the hybrid battery (traction battery),
the speed of the vehicle, etc.
OEven if there is enough charge
remaining in the hybrid battery (trac-
tion battery), EV driving may be can-
celed and both gasoline engine and
electric motor are used depending on
the situation. (P.90)
QEV indicator
The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.
The on/off operation of the EV indicator
can be changed. (P.184)
QAfter 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
etc. 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.
QGasoline engine operation in EV
mode or AUTO EV/HV mode
Even if there is a sufficient amount of
electricity remaining in the hybrid battery
(traction battery) and EV driving range
(P.179) is being displayed on the
multi-information display, EV driving
(driving using only the electric motor)
may be canceled and both gasoline
engine and electric motor are used
depending on the situation (EV driving
will be returned to automatically after EV
driving becomes possible again).
EV driving may be canceled automati-
cally in the following circumstances
*1:
OWhen vehicle speed is more than
approximately 135 km/h (84 mph).
OWhen power is needed temporarily,
for example when the accelerator
pedal is depressed firmly or when
accelerating suddenly.
*2
OWhen 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.
OWhen the temperature of the hybrid
system is low.
OWhen the heater is switched on when
the outside temperature is below
about -10°C (14°F).
OWhen the windshield defogger switch
is pressed. (P.407)
OWhen the system determines that the

gasoline engine needs to be started.*1: The gasoline engine may also oper-
ate in circumstances other than those
listed above, depending on condi-
tions.
*2: When driving in AUTO EV/HV mode.
Even in EV mode, the gasoline
engine may start, depending on the
condition of the hybrid battery (trac-
tion battery).
QIf “Engine Started to Protect Sys-
tem EV driving unavailable” is dis-
played on the multi-information
display
EV driving may be canceled in order to
protect the hybrid system, etc.
In this case, perform driving with the
gasoline engine until EV driving will be
returned to automatically.
QConditions in which the gasoline
engine may not stop
The gasoline engine starts and stops
automatically. However, it may not stop
automatically in the following condi-
tions
*:
ODuring gasoline engine warm-up
ODuring hybrid battery (traction battery)
charging
OWhen the temperature of the hybrid
battery (traction battery) is high or low
OWhen the windshield defogger switch
is pressed. (P.407)
*: Depending on the circumstances, the
gasoline engine may also not stop
automatically in situations other than
those above.
QSounds and vibrations specific to a
Plug in Hybrid Electric Vehicle
There may be no engine sound or vibra-
tion even though the vehicle is able to
move with the “READY” indicator is illu-
minated. For safety, apply the parking
brake and make sure to shift the shift
lever to P when parked.The following sounds or vibrations may
occur when the hybrid system is operat-
ing and are not a malfunction.
OMotor sounds may be heard from the
engine compartment.
OSounds may be heard from the hybrid
battery (traction battery) when the
hybrid system starts or stops.
ORelay operating sounds such as a
snap or soft clank will be emitted from
the hybrid battery (traction battery),
behind the rear seats, when the hybrid
system is started or stopped.
OSounds from the hybrid system may
be heard when the back door is open.
OSounds may be heard from the trans-
mission when the gasoline engine
starts or stops, when driving at low
speeds, or during idling.
OEngine sounds may be heard when
accelerating sharply.
OSounds may be heard due to regener-
ative braking when the brake pedal is
depressed or as the accelerator pedal
is released.
OVibration may be felt when the gaso-
line engine starts or stops.
OCooling fan sounds may be heard
from the air intake vent under the rear
seat. (P.98)
OSounds may be heard from near the
hybrid battery (traction battery) in
accordance with the operation of the

QMaintenance, repair, recycling, and
disposal
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer regarding mainte-
nance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.
In order to make EV mode or AUTO
EV/HV mode available, charge the
Charging (P.105)

922-1. Plug-in hybrid system
hybrid battery (traction battery)
from an external power source
before using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven. How-
ever, if there is not enough charge
remaining, it is possible that the vehicle
cannot be driven in EV mode or AUTO
EV/HV mode, or the EV driving range
will become shorter.
QRefilling fuel
Plug in Hybrid Electric Vehicles can be
driven using electricity charged from an external power source. However, as the gasoline engine is used depending on
the situation ( P.90) even if in EV mode or AUTO EV/HV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immedi-
ately when the fuel level becomes low. ( P.298)
QIf the vehicle is not used for a long time
OThe 12-volt battery may discharge. In
this event, charge the 12-volt battery. ( P.546) In order to prevent the hybrid battery
(traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) 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
passed since the “READY” indicator came on, the power switch can be turned to off without any further
action.) When the 12-volt battery is dis-charged, refer to “If the 12-volt battery
is discharged” ( P.546) and perform the correction procedure.
OWhen the vehicle is left with the AC charging cable connected, the elec-tricity consumption amount of the 12-
volt battery increases due to controls, such as the system checking, operat-ing. When the AC charging cable is
not needed, remove it from the vehi- cle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of the
vehicle’s approach. The sound will
stop when the vehicle speed
exceeds approximately 25 km/h (15
mph).
