■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.

962-1. Plug-in hybrid system
WARNING
●Never touch, disassemble, remove
or replace the high voltage parts,
cables or their connectors.
●The hybrid system will become hot
after starting a s the system uses high voltage. Be careful of both the
high voltage and the high tempera -
ture, and always obe y the caution
labels attached to the vehicle.
●Never try to open the service plug
access hole located in the luggage compartment. The service plug is
used only when the vehicle is ser-
viced and is subject to high voltage.
■Road accident cautions
Observe the following precautions to reduce the risk of d eath or serious
injury:
●Pull your vehicle off the road, apply
the parking brake, shift the shift
lever to P, and tu rn the hybrid sys- tem off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehi cle, an electric
shock may occur. Never touch
exposed electric wires.
●Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte ( carbonic-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 unlik ely event that it
comes into contact with the eyes or
skin, wash it off immediately with a large amount of w ater, 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
damaged, the internal construction of the battery wil l prevent a large
amount of electrolyte from leaking
out. However, any electrolyte that does leak out will g ive off a vapor.
This vapor is an irritant to skin and
eyes and could c ause 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.
●If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possi - ble. Never use a f ire extinguisher
that is not meant fo r electric fires.
Using even a small amount of water may be dangerous.
●If your vehicle nee ds to be towed, do so with front wheels 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.563)
●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.

WARNING
■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 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 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 ex plosion and elec-
trolyte 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.
●If your vehicle is disposed of with- out the hybrid bat tery having been
removed, there is a danger of seri -
ous electric shock if high voltage parts, cables and their connectors
are touched. In t he event that your
vehicle must be disposed of, the hybrid battery mus t 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.
■Caution 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 th e 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 contac t any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■Modifications
Do not modify the v ehicle 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 bat tery) is damaged, a vehicle fire may occur which could
lead to death or serious injury.

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)

Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity canno t be generated.
Also, when using the air condition -
ing system, etc., the hybrid battery
(traction battery) power is con -
sumed.
 Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera -
tion and deceler ation will make
more effective use of the electric
motor (traction motor) without
having to use gasoline engine
power.
 Avoid repeated acceleration.
Repeated acceleration con -
sumes hybrid battery (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and a ti mely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceler ation and decel-
eration, as well as long waits at traf -
fic lights, will lead to high fuel and
electricity consumption. Check traf -
fic reports before leaving and avoid
delays as much as possible. When
driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly
while avoiding overuse of the accel -
erator pedal. Doing so can help
control excessive electricity and
fuel consumption.
 Control and maintain the vehicle
at a constant speed. Before stop -
ping at a toll booth or similar,
allow plenty of time to release
the accelerator and gently apply
the brakes. A greater amount of
electrical energy can be regener -
ated when slowing down.
 Electricity consumption will
increase significantly when driv -
ing at high speeds in EV mode or
AUTO EV/HV mode. If there will
be a long distance to the next
external charging point after
leaving a freewa y, it is recom-
mended to drive in HV mode

The value displayed on the SOC
(State of Charge) gauge ( →P.174)
is estimated from the following
information.
 The amount of hybrid battery
(traction battery) charge cur -
rently remaining
 The electricity consumption (the
estimated distan ce that EV driv-
ing is possible pe r unit of electri-
cal energy) based on the
recorded value
 Past air conditioning system
electricity consumption amount
The electricity co nsumption varies
depending on how the vehicle is
driven. The vehicle automatically
records the electricity consumption
when being charged and uses the
electricity consumption for estimat -
ing the EV driving range. Therefore,
the EV driving ra nge displayed
when the hybrid battery (traction
battery) is fully charged may differ
from the previous EV driving range
depending on how the vehicle was
driven.
The EV driving r ange may change
significantly with each charging
until the electricity consumption
based on the recorded value is sta -
ble (for approximately the first
month or two). However, this does
not indicate a malfunction.
When the air conditioning system is
turned on, the EV driving range
(with using the air conditioning sys -
tem) is estimated based on the past
air conditioning electricity con -
sumption amount considering that
the electricity consumption may
become higher.
The distance that EV driving is pos -
sible varies signi ficantly depending
on how the vehicle is driven, road
conditions, the weather, the outside
temperature, usage conditions of
electrical components and the num -
ber of occupants.
The distance that EV driving is pos -
sible can be extended if the follow -
ing is performed:
EV driving range
The EV driving range displayed
on the multi-information dis -
play shows the reference dis -
tance that EV driving (driving
using only the electric motor)
is possible, and the actual dis-
tance that can be driven may
differ from that displayed.
Even if the EV dr iving range is
displayed, EV driving may be
canceled and both gasoline
engine and electric motor are
used depending on the situation.

■When starting off, depress the
accelerator pedal smoothly to
accelerate
As a guide, acce lerate up to
approximately 20 km/h (12mph) in
the first 5 seconds.
Electrical and fuel efficiency can be
improved just by using the ECO
Accelerator Guidance displayed on
the multi-informat ion display and
taking care to start off gently.
( →P.182)
When the driving mode is set to Eco
drive mode, depressing the accelerator
pedal generates smooth torque that
makes it easier to operate the accelera -
tor gently.
■Maintain sufficient vehicle-to-
vehicle distance and do not
accelerate or decelerate
unnecessarily
Try to maintain a fixed speed while
driving. Driving at a short vehicle-
to-vehicle distance will result in
repeating wasteful acceleration and
deceleration, which will worsen the
electrical and fuel efficiency.
■Release the accelerator pedal
early before stopping the vehi -
cle, such as at a traffic light
The regenerative brake will operate
to convert the kinetic energy of the
vehicle into electrical energy, which
will charge the hyb rid battery (trac-
tion battery).
The regeneration status can be
checked from the Hybrid System
Indicator. ( →P.177)
When the brake pedal is depressed
lightly during deceleration, the
regeneration amount increases,
enabling more electrical energy to
be recovered.
If the brake pedal is depressed too
strongly, the recovered amount indica -
tor will reach the maximum level and
the upper limit of the recoverable
energy will be exceeded. Therefore, be
sure to operate the brake pedal early.
■Use the air co nditioning sys-
tem appropriately, and also
utilize the heated steering
wheel (if equipped) and seat
heaters
In EV mode, the vehicle is cooled
and heated by electrical energy.
(Except in extremely cold tempera -
tures of approximately -10°C (14°F)
or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and improve
electrical efficiency.
The heated steering wheel (if
equipped) and seat heaters are effi -
cient heating device that directly
warm the body using less electric
power.
When used together with the air condi -
tioning system, a low temperature set-
ting can be used to improve electrical
and fuel efficiency.
■Check the tire pressure
If the tire pressure is lower than the
specified value, i t will worsen the
electrical and fuel efficiency.
