■Electromagnetic waves
●High-voltage parts and cables on the battery electric vehicles incorporate electro-magnetic shielding, and there-
fore emit approximately the same amount of electromagnetic waves as conventional gasoline-powered vehi-
cles or home electronic appliances.
●Your vehicle may cause sound inter-
ference in some third party-produced radio parts.
■Traction battery (Lithium-ion bat-tery)
The traction battery has a limited service life.
The traction battery capacity (the ability
to store energy) reduces with time and use in the same way as other recharge-able batteries. The extent at which
capacity reduces changes drastically depending on the environment (outside temperature, etc.) and usage conditions,
such as how the vehicle is driven and how the traction battery is charged.
This is a natural characteristic of lithium-
ion batteries, and is not a malfunction. Also, even though the driving range decreases when the traction battery
capacity reduces, vehicle performance does not significantly become worse. In order to reduce the possibility of the
capacity reducing, follow the directions listed on P.119, “Capacity reduction of the traction battery”.
■Starting the EV system in an
extremely cold environment
When the traction battery is extremely cold (below approximately -30°C [-
22°F]) due to the temperature outside of
the vehicle, it may not be possible to start the EV system. In this case, try to
start the EV system again after the tem- perature of the traction battery increases due to the outside temperature increas-
ing, etc.
■Declaration of conformity
This model conforms 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 systems are 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 (orange) or their connectors.
●The EV 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.

WARNING
●Never try to open the service plug access hole located under the floor.
The service plug is used only when the vehicle is being serviced and is subject to high voltage.
■Road accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
●Stop the vehicle in a safe place to
prevent subsequent accidents. While depressing the brake pedal, apply the parking brake and shift
the shift position to P to stop the EV system. Then, slowly release the brake pedal.
●Do not touch the high voltage parts, cables (orange) and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
●Do not touch the traction battery if liquid is leaking from or adhered to it. If electrolyte (Organic Carbonate-
based electrolyte) from the traction battery comes into contact with the eyes or skin, it could cause blind-
ness or skin wounds. In the unlikely event that it comes into contact with the eyes or skin, wash it off immedi-
ately with a large amount of water, and seek immediate medical atten-tion.
●If electrolyte is leaking from the traction battery, do not approach the vehicle.
Even in the unlikely event that the traction battery has been damaged, the internal construction of the bat-
tery will prevent a large amount of electrolyte from leaking out. How-ever, if electrolyte leaks, vapors will
be emitted. These vapors are an irritant to skin and eyes and could cause acute poisoning 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 battery electric vehicle, leave the vehicle as soon as possible. Never use a fire extin-
guisher that is not meant for electri- cal fires. Using even a small amount of water may be danger-
ous.
●If your vehicle needs to be towed,
be sure to transport the vehicle with the front wheels (2WD models) or four wheels (AWD models) raised.
If the vehicle is towed with the wheels which are connected to the electric motor (traction motor) con-
tacting the ground, electricity gener- ated by the operation of the motor may cause a fire to occur depend-
ing on the nature of the damage or malfunction. ( P.509)

WARNING
●Carefully inspect the ground under the vehicle. If leaked liquid (other
than water from the air condition- ing) is found on the ground, the traction battery may have been
damaged. Leave the vehicle as soon as possible. In addition, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer with regard to the leakage found on
the ground. Even in the event of a minor acci-dent, the traction battery and sur-
rounding parts may be damaged. In case of an accident, have the trac-tion battery inspected at any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Traction battery
●Your vehicle contains a sealed lith-
ium-ion battery.
●Never resell, hand over or modify
the traction battery. To prevent acci- dents, traction 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:
• Do not illegally dispose of or dump the traction battery, and it is hazard-ous to the environment or someone
may touch a high voltage part, resulting in an electric shock.
• The traction battery is intended to be used exclusively with your bat-tery electric vehicle. If the traction
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 hand-
ing over your vehicle, the possibility of an accident is extremely high because the person receiving the
vehicle may not be aware of the dangers from these modifications.
●If your vehicle is disposed of with-out the traction 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 traction 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 traction battery is
not disposed of properly, it may cause electric shock that can result in death or serious injury.
●For information about traction bat-tery collection locations, contact
information, or the recycling pro- cess, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■Caution while driving
●Pay special attention to the area around the vehicle. Because there is no engine noise, pedestrians,
people riding bicycles or other peo- ple and vehicles in the area may not be aware of the vehicle starting
off or approaching them, so take extra care while driving. Therefore, take extra care while driving even if
the Acoustic Vehicle Alerting Sys- tem is active.

When a certain level of impact is
detected by the impact sensors, the
emergency shut off system turns off
the EV system and blocks the high
voltage current. If the emergency
shut off system activates, your vehi-
cle will not restart. To restart the EV
system, 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 EV system or an improper
operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the instruc-
tions. ( P.160, 523)
■If a warning light comes on, a warn- ing message is displayed, or the 12-volt battery is disconnected
The EV 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 reliable repairer.
■When the traction battery is com-
pletely discharged
When the EV system cannot be started due to the traction battery being com-
pletely discharged, restart the system after AC charging or DC charging. When
charging, it is recommended to charge the traction battery until the traction bat-tery charge warning light turns off in
order to ensure sufficient driving dis- tance.
WARNING
●If the vehicle under floor area receives strong shock or impact
while driving, stop the vehicle in a safe place and check around the bottom of the vehicle. If there is
damage to the traction battery or liquid leakage, it may lead to a vehi-cle fire, etc. Do not touch the vehi-
cle and immediately contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. Even if no damage can be seen under the floor, the traction battery
may be damaged. If the vehicle received an impact under the floor, have the traction battery inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Modifications
Do not make modifications that lower
the height of the vehicle. The traction battery in the under floor area may come into contact with the ground
when the height of vehicle is lowered. If the traction battery is damaged, a vehicle fire may occur, possibly result-
ing in death or serious injury.

Shift the shift position to D when
stopped at a traffic light, or driving
in heavy traffic, etc. Shift the shift
position to P when parking. When
shifting the shift position to N while
driving, there is no positive effect
on electricity consumption. In the N,
the traction battery cannot be
charged. Also, when using the air
conditioning system, etc., the trac-
tion battery electricity is consumed.
( P.248)
Repeated acceleration and decel-
eration due to traffic congestion,
long waits at traffic lights, and driv-
ing on steep inclines will lead to
poor electricity consumption. In
order to avoid those situations as
much as possible, check traffic
reports before leaving. If the vehicle
is driven in traffic congestion, gently
release the brake pedal to allow the
vehicle to move forward slightly,
avoid overuse of the accelerator
pedal. Doing so can help minimize
unnecessary electricity consump-
tion.
Make sure to operate the brakes
gently and a timely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Control and maintain the vehicle at
a constant speed. Before stopping
at a toll booth or similar, allow
plenty of time to release the accel-
erator and gently apply the brakes.
A greater amount of electrical
energy can be regenerated when
slowing down.

driving tips
Unlike the conventional vehi-
cles, the electricity consump-
tion efficiency of battery
electric vehicles will decline if
they continue driving on high-
ways (or freeways) or at high
average speeds, causing the
possible driving distance to
reduce. Therefore, if the
remaining charge of the trac-
tion battery is low, avoid rely-
ing on the displayed possible
driving distance too much as
well as driving on highways (or
freeways). Driving the vehicle
at moderate speeds, the trac-
tion battery’s electricity con-
sumption can be controlled.
The following driving tips will
contribute to reduction in the
battery consumption and
increase in the driving range.

Use the air conditioning only
when necessary. Doing so can
help reduce excessive electricity
consumption.
In summer: When the ambient tem-
perature is high, use the recirculated air
mode. Doing so will help to reduce the
burden on the air conditioning system
and reduce electricity consumption as
well.
In winter: Excessive or unnecessary
heating should be avoided. Also, elec-
tricity consumption can be improved by
avoiding overuse of the heater.
 When using the Remote Air Con-
ditioning System ( P.427) while
the AC charging cable is con-
nected to the vehicle, electricity
consumption immediately after
starting off will be reduced
because air conditioning is oper-
ated mainly using electricity from
an external power source.
Make sure to check the tire inflation
pressure frequently. Improper tire
inflation pressure can cause poor
electricity consumption.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads will lead to poor electricity
consumption. Use tires that are
appropriate for the season.
Carrying heavy luggage will lead to
poor electricity consumption. Avoid
carrying unnecessary luggage.

A value for which a sufficient level
of driving performance can be pro-
vided is estimated based on the
remaining charge of the traction
battery, the state of the traction bat-
tery, the outside temperature, etc.,
and is displayed on the multi-infor-
mation display. ( P.172)
When the outside temperature is
low, the traction battery output may
be decreased, causing the possible
driving distance to be shorter. How-
ever, this is not a malfunction.
Charge the traction battery earlier
than usual.
Possible driving distance varies sig-
nificantly depending on how the
vehicle is driven, road conditions,
the weather, the outside tempera-
ture, usage conditions of electrical
components and the number of
occupants.
Possible driving distance could be
extended if the followings are per-
formed:
 Maintain a safe distance from the
vehicle in front and avoid unnec-
essary acceleration and deceler-
ation
 Accelerate and decelerate the
vehicle as smoothly as possible
 Drive at moderate speeds as
much as possible and maintain a
constant speed
 Set the air conditioning system to
a moderate temperature and
avoid using the heating and cool-
ing functions excessively.
 Use tires of the specified size
and maintain the specified tire
pressure
 Do not add unnecessary weight
to the vehicle
The followings indicate that
charging has been carried out prop-
erly.
 The charging indicator turns off
 “Charging complete” is displayed
on the multi-information display
when a door is opened while the
power switch is off. ( P.117)
