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 the shift lever is in N, the
hybrid battery (traction battery) is
not being charged.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine
is warming up, etc., the gasoline
engine will not automatically stop.
( P. 7 6 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the hybrid
battery (traction battery) as neces-
sary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine
via the electric motor (traction
motor).
■When braking (regenerative
braking)
The wheels operate the electric
motor (traction motor) as a power
generator, and the hybrid battery
(traction battery) is charged.
■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 (trac-
tion battery). • The accelerator pedal is released while driving with the shift lever in D or
B. • The brake pedal is depressed while driving with the shift lever in D or B.
●Vehicles with GPF system: While the GPF system ( P.335) is operating to
regenerate the exhaust gas filter, the hybrid battery (traction battery) may not be recharged.
■EV indicator
The EV indicator comes on when the vehicle is driven using only the electric motor (traction motor) or the gasoline
engine is stopped.
■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
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
Depending on the circumstances, the
gasoline engine may also not stop auto- matically in other situations.
■Charging the hybrid battery (trac-tion battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-tery does not need to be charged from
an outside source. However, if the vehi- cle is left parked for a long time the hybrid battery (traction battery) will

starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted from the hybrid battery (traction battery), under the rear seats, when the hybrid
system is started or stopped.
●Sounds from the hybrid 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 the brake pedal is depressed or as the accelerator pedal is released.
●Vibration may be felt when the gaso-line engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of
the lower part of the rear left seat.
■Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any reli- able repairer regarding maintenance, repair, recycling and disposal. Do not
dispose of the vehicle yourself.

When the gasoline engine is off
while driving, a sound is produced
to warn pedestrians, people riding
bicycles or other people and vehi-
cles in the surrounding area that
the vehicle is approaching. The
pitch of the sound adjusts accord-
ing to vehicle speed. When vehicle
speed is approximately 25 km/h (16
mph) or more, the warning system
turns off.

■Running 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.442) 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 6.3 L [1.7
gal., 1.4 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.)
■Electromagnetic waves
●High voltage parts and cables on
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.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has
a limited service life. The lifespan of the hybrid battery (traction battery) can change in accordance with driving style
and driving conditions.
■Starting 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.
■Declaration of conformity
This model conforms to hydrogen emis-
sions according to regulation ECE100
(Battery electric vehicle safety).
WARNING
■High voltage precautions
This 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.
●Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
●The hybrid system will become hot
after starting as the system uses high voltage. Be careful of both the high voltage and the high tempera-
ture, and always obey the warning labels attached to the vehicle.
●Never try to open the service plug access hole located under the left side of the rear seat. The service
plug is used only when the vehicle is serviced and is subject to high voltage.
■Road accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and turn the hybrid sys-
tem off.

WARNING
●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.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possi-ble. 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 the front wheels (2WD
models) or four wheels (AWD mod- els) raised. If the wheels connected to the electric motor (traction motor)
are on the ground when towing, the motor may continue to generate electricity. This may cause a fire.
( P.433)
●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 possi- ble.
●Do not touch the battery if liquid is leaking from or adhering to it. If electrolyte (carbonate ester-based
organic electrolyte) from the hybrid 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 battery), do not approach the vehicle. Even in
the unlikely event that the hybrid battery (traction battery) is dam-aged, the internal construction of
the battery will prevent a large amount of electrolyte from leaking out. However, any electrolyte that
does leak out will give off a vapor. This vapor is an irritant to skin and eyes and could cause acute poi-
soning if inhaled.
●Do not bring burning or high-tem-
perature items close to the electro- lyte. The electrolyte may ignite and cause a fire.
■Hybrid battery (traction battery)
●Your vehicle contains a sealed lith-
ium-ion battery.
●Never 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 col-
lected, 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 hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified in any way, accidents such as elec-
tric shock, heat generation, smoke generation, an explosion and elec-trolyte leakage may occur.

There is an air intake vent under
the left side of the rear seat for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vent
becomes blocked, the hybrid bat-
tery (traction battery) input and out-
put may be reduced.
When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks
the high voltage current and stops
the fuel pump to minimize the risk
of electrocution and fuel leakage. If

WARNING
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.
●If 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. If the hybrid bat-
tery is not disposed of properly, it may cause electric shock that can result in death or serious injury.
