• If electricity needed for EV driv-
ing in EV mode or AUTO EV/HV
mode is not remaining, the oper-
ation mode will be automatically
switched to HV mode.
• The operation mode can be
switched to HV mode at any tim-
ing by operating the switch to
keep electricity for EV driving
etc.
* (P.86). Switching to HV
mode when driving on a highway
or when driving uphill is recom-
mended in order to conserve bat-
tery power.
When in HV mode, the HV drive mode
indicator illuminates.
*: The EV driving range may reduce
even after switching to HV mode.
QHybrid battery (traction bat-
tery) charge mode (P.87)
Electricity generated in the gasoline
engine can be charged in the hybrid
battery (traction battery) by switch-
ing to the hybrid battery (traction
battery) charge mode when elec-
tricity needed for EV driving is not
remaining.
*
• The system may not be able to switch to the hybrid battery (trac-
tion battery) charge mode due to
the state of the plug-in hybrid
system. (P.88)
• Charging time differs depending
on the driving state of the vehicle
when driving in hybrid battery
(traction battery) charge mode.
When in the hybrid battery (traction bat-
tery) charge mode, the hybrid battery
charge mode indicator illuminates.
*: When in the hybrid battery (traction
battery) charge mode, the hybrid bat-
tery can be charged while driving.
However, the gasoline engine runs to
charge the battery and fuel consump-
tion becomes higher compared with
driving in HV mode.
The plug-in hybrid system opera-
tion modes can be switched using
the switches.
QSwitching the plug-in hybrid
system operation modes
Press the AUTO EV/HV mode
switch or EV/HV mode selection
switch to change modes as the fol-
lowing table shows.
When in EV mode, the EV drive mode
indicator illuminates.
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
When in HV mode, the HV drive mode
indicator illuminates.

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

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).
QAcoustic Vehicle Alerting System
In the following cases, the Acoustic
Vehicle Alerting System may be difficult for surrounding people to hear.

QRunning out of fuel
When the vehicle has run out of fuel and
the hybrid system cannot be started, refuel the vehicle with at least enough gasoline to make the low fuel level warn-
ing light ( P.515) go off. If there is only a small amount of fuel, the hybrid sys-tem may not be able to start. (The stan-
dard amount of fuel is about 8.8 L [2.3 gal., 1.9 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)
QElectromagnetic waves
OHigh voltage parts and cables on the Plug in Hybrid Electric Vehicles incor-porate electromagnetic shielding, and
therefore emit approximately the same amount of electromagnetic waves as conventional gasoline pow-
ered vehicles or home electronic appliances.
OYour vehicle may cause sound inter-ference in some third party-produced radio parts.
QEffect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are placed inside the luggage compartment
or installed nearby, the generated mag- netic forces may negatively affect the hybrid system.
QHybrid battery (traction battery)
(lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge) reduces with time and use in the same
way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how the vehicle is driven and how the hybrid bat-
tery (traction battery) is charged. This is a natural characteristic of lithium-ion batteries, and is not a malfunction. Also,
even though the EV driving range becomes shorter when the hybrid bat-tery (traction battery) capacity reduces,
vehicle performance does not signifi- cantly become worse.
In order to reduce the possibility of the
capacity reducing, follow the directions listed on P.133, “Capacity reduction of the hybrid battery (traction battery)”.
QStarting the hybrid system in an
extremely cold environment
When the hybrid battery (traction bat- tery) is extremely cold (below approxi-
mately -30°C [-22°F]) under the influence of the outside temperature, it may not be possible to start the hybrid
system. In this case, try to start the hybrid system again after the tempera-ture of the hybrid battery increases due
to the outside temperature increase etc.
QDeclaration of conformity
This model conforms to hydrogen emis- sions according to regulation ECE100
(Battery electric vehicle safety).

WARNING
OCarefully 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 possi-
ble.
QHybrid battery (traction battery)
OYour vehicle contains a sealed lith- ium-ion battery.
ONever resell, hand over or modify the hybrid battery. To prevent acci-dents, hybrid batteries that have
been removed from a disposed vehicle are collected through any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. Do not dispose of the bat-tery yourself. Unless the battery is
properly collected, the following may occur, resulting in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is
hazardous to the environment or someone may touch a high voltage part, resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your Plug in
Hybrid Electric Vehicle. If the hybrid battery is used outside of your vehi-cle or modified in any way, acci-
dents 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.
OIf your vehicle is disposed of with-out the hybrid battery having been removed, there is a danger of seri-
ous 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 must be disposed of by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer, or a qualified ser-vice shop. If the hybrid battery is
not disposed of properly, it may cause electric shock that can result in death or serious injury.
QCaution while driving
If the vehicle under floor area
receives strong shock or impact while driving, stop the vehicle in a safe area and check around the bottom of the
vehicle. If there is damage to the hybrid battery (traction battery) or liq-uid leakage, it may lead to a vehicle
fire, etc. Do not touch the vehicle and immediately contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
QModifications
Do not modify the vehicle to make the height lower.
It is easier for the hybrid battery (trac-
tion battery) in the under floor area to come in contact with the ground when the vehicle is lowered. If the hybrid
battery (traction battery) is damaged, a vehicle fire may occur which could lead to death or serious injury.

QNotice about fuel
OFor Plug in Hybrid Electric Vehicles,
fuel may remain in the tank for a long time and undergo changes in quality depending on the how the
vehicle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least
20 L [5.3 gal., 4.4 Imp.gal.] over a 12-month period), as this may affect components of the fuel sys-
tem or the gasoline engine.
OIf the vehicle has not been refueled
for a certain amount of time and it is possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to ON. If the message is displayed, refuel the vehicle immediately.

NOTICE
QDC/DC converter air intake vent
OMake sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug-gage. Blocking the air intake vent
may prevent the plug-in hybrid sys- tem from operating properly.
OWhen dust etc. has accumulated in the air intake vent, clean it with a vacuum cleaner to prevent the vent
from clogging.
ODo not wet or allow foreign sub-
stances to enter the air vent as this may cause a short circuit and dam-age the DC/DC converter.
ODo not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
OA filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to P.479.
OIf “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown on the
multi-information display, the air intake vent and filter may be clogged. Refer to P.479 for informa-
tion on how to clean the air intake vent.

Primarily using EV mode and
AUTO EV/HV mode when driving in
cities and using HV mode when
driving on highways (or freeways)
can help conserve fuel and electric-
ity. (P.86)
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
fuel and electricity economy.
