Rear electric motor (traction motor)
Plug-in hybrid system features
The plug-in hybrid system is a system excellent in both economi cal
efficiency of electric vehicles and practicality of hybrid vehicles.
 EV driving can be performed using electricity charged from an external
power source.*
 If the amount of electricity remaining in the hybrid battery (traction bat-
tery) becomes low, the vehicle is automatically controlled in such a
way that it can be driven as a hybrid vehicle through the joint use of the
gasoline engine.
*: The EV driving range will vary i n accordance with conditions such as vehicle
speed, the amount of c harge remaining in the hybrid battery (traction battery)
and the usage of the air conditioning system. The gasoline engi ne may also be
used simultaneously in accordan ce with driving conditions.

be changed even if the AUTO EV/HV
mode switch or EV/HV mode selection switch is pressed. ( In this case, the
warning message is displayed on the
multi-information display when the switch is pressed.)
●When electricity needed for EV driving is not remaining (when in EV mode or
AUTO EV/HV mode)
●When the traction battery is almost
completely charged (hybrid battery
[traction battery] charge mode)
■When switching from EV mode to another mode using the switch
●After switching from EV mode to HV
mode or hybrid battery (traction bat - tery) charge mode and the power
switch is turned off, the system
returns to EV mode the next time the
vehicle is started.*
●After switching from EV mode to
AUTO EV/HV mode and the power switch is turned o ff, the system does
not return to EV mode the next time
the vehicle is started.*
*: If there is not enough charge remain-
ing in the hybrid battery (traction bat -
tery) to allow EV dr iving, the system
switches to HV mode.
■Hybrid battery (tr action battery) charge mode
●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (trac -
tion battery) char ge mode or cannot cancel it
• Gasoline engine does not start or
stops even after s witching to hybrid battery (traction battery) charge mode
●If a load to the syst em is large, such
as when the power consumption of the air conditioning system is large or
when the temperatur e 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.
■When in EV mode
In EV mode, EV driving (driving
using only the electric motor)* is
possible. Howeve r, 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.
If you repeatedly accelerate, the
hybrid battery (traction battery)
WARNING
■When using the hybrid battery (traction battery ) charge mode
Observe the following precautions
when using the hybrid battery (trac - tion battery) char ge 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.
●Do not stop the vehicle near flam -
mable materials.
●Do not use the hybrid battery (trac -
tion battery) charge mode in a
closed area where ventilation is insufficient, such a s in a garage or
area with snow buildup.

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).
■If “Engine Started to Protect Sys -
tem EV driving unavailable” is dis - played on the mu lti-information
display
EV driving may be canceled in order to protect the hybr id system, etc.
In this case, perform driving with the
gasoline engine until EV driving will be returned to automatically.
■Conditions in which the gasoline
engine may not stop
The gasoline engine starts and stops automatically. Howev er, it may not stop
automatically in the following condi -
tions*:
●During gasoline engine warm-up
●During hybrid battery (traction battery)
charging
●When the temperature of the hybrid
battery (traction batt ery) is high or low
●When the windshield defogger switch
is pressed. ( →P.453)*: Depending on the circumstances, the
gasoline engine may also not stop
automatically in sit uations other than
those above.
■Sounds and vibrations specific to a
hybrid 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 o r vibrations may
occur when the hyb rid system is operat- ing 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 emitted from
the hybrid battery ( traction battery), behind the rear seats, when the hybrid
system is started or stopped.
●Sounds from the hy brid system may
be heard when the back door is open.
●Sounds may be heard from the trans -
mission 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 regener - ative braking when t he brake pedal is
depressed or as the accelerator pedal
is released.
●Vibration may be f elt when the gaso-
line engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vent under the rear seat. ( →P.98)
●Sounds may be heard from near the hybrid battery (traction battery) in
accordance with th e operation of the
air conditioning syst em or “Battery Cooler” ( →P.129).
■Maintenance, repair, recycling, and
disposal
Contact any authoriz ed Toyota retailer
or Toyota authorized repairer, or any reliable repairer regarding mainte -
nance, repair, recycling and disposal.
Do not dispose of the vehicle yourself.

■Running out of fuel
When the vehicle has run out of fuel and
the hybrid system c annot be started, refuel the vehicle with at least enough
gasoline to make the low fuel level warn -
ing light ( →P.575) 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.], w hen 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.)
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro -
magnetic shielding, and therefore emit
approximately the same amount of electromagnetic waves as conven -
tional gasoline powered vehicles or
home electronic appliances.
●Your vehicle may cause sound inter -
ference in some third party-produced radio parts.
■Effect 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.
■Hybrid battery (tr action 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 a nd 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 batter y) capacity reduces, vehicle performance does not signifi -
cantly become worse.
In order to reduce th e possibility of the capacity reducing, follow the directions
listed on P.134, “Capacity reduction of
the hybrid battery ( traction battery)”.
■Starting the hybrid system in an extremely cold environment
When the hybrid battery (traction bat -
tery) is extremely c old (below approxi- mately -30°C [-22°F]) under the
influence of the outsi de 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 hy brid battery increases due to the outside temperature increase etc.
■Declaration of conformity
This model conform s to hydrogen emis-
sions according to regulation ECE100 (Battery electric vehicle safety).

WARNING
■High voltage precautions
The vehicle has high voltage DC and
AC systems as well as a 12-volt sys- tem. DC and AC high voltage is very
dangerous and can cause severe
burns and electric shock that may result in death or serious injury.

Plug-in hybrid system
stops the fuel pump to minimize the
risk of electrocuti on and fuel leak-
age.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the hybrid sys -
tem, contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
A message is automatically dis -
played when a malfunction occurs
in the hybrid system or an improper
operation is attempted.
If a warning message is shown on
the multi-informat ion display, read
the message and follow the instruc -
tions.
■If a warning light comes on, a warn - ing message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that
case, try to start the system again. If the “READY” indicator does not come on,
contact any authorized Toyota retailer or
Toyota authorized repairer, or any reli - able repairer.
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 minim ized, improving
fuel and electricity economy.
( →P.434)
Eco-friendly driving is possible by
keeping the Hybrid System Indica -
tor within Eco area. ( →P.177)
