Owners Manual_USA_M42C01_en
■Charging the traction battery
Be sure to maintain the traction bat-
tery charge level suitable for your
driving needs.
If the traction battery fully dis-
charges, the vehicle cannot be
driven at all. When the battery
becomes low, charge it as soon as
possible.
■If the traction battery becomes
low
●If the traction battery becomes
low, the traction battery charge
warning light comes on or flashes
and a message will be displayed
on the multi-information display.
(  P.515)
●If the traction batte ry is completely
discharged, the EV system cannot
be started and dri ving will not be
possible. When the traction bat-
tery becomes low, charge it as
soon as possible.
■Sounds and vibrations specific
to an battery electric vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
battery electric vehi cle for being off
when it is actually still running, as
indicated by the “READY” indicator
being illuminated. F or safety, make
sure to always shift the shift position
to P and apply the parking brake
when parked.
Before and after the EV system is
started, the following sounds and
vibrations may occur. However,
these sounds and/o r vibrations are
not signs of malfunctions:
●The brake system operation
sound may be heard from the
front of the vehicle when the
driver’s door is opened.
●Motor sounds may be heard from
the motor compartment or lug-
gage compartment.
●Electrical relay sounds may be
heard from the motor compart-
ment when the EV system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the traction b
attery in the fol-
lowing situations:
• When the EV system is started or stopped
• When charging starts or com-
pletes
• When the vehicle is driven the first time after the traction battery has
been charged using DC charging
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Cooling fan operating sounds
from the radiator.
●The operation sound of the air
conditioning system (air condition-
ing compressor, blower motor).
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
A sound which changes in
accordance with the driving
speed, will be played in order to
warn people nearby of the vehi-
cle’s approach. This sound may
be heard inside the vehicle. The
sound will stop when the vehicle
speed exceeds approximately
23 mph (37 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.

■Electromagnetic waves
●High-voltage parts and cables on
the battery electric vehicles incor-
porate electro-magnetic shield-
ing, and the refore emit
approximately the same amount
of electromagnetic waves as con-
ventional gasoli ne-powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Traction battery (Lithium-ion
battery)
The traction batte ry has a limited
service life.
The traction battery capacity (the
ability to store ene rgy) 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 (outside tempera-
ture, etc.) and us age 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 sig-
nificantly become worse. In order to
reduce the possibility of the capacity
reducing, follow the directions listed
on P.103, “Capacity reduction of the
traction battery”.
■Starting the EV system in an
extremely cold environment
When the traction battery is
extremely cold (below approxi-
mately -22°F [-30°C]) 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 tempera-
ture of the traction battery increases
due to the outside temperature
increasing, etc.
WARNING
■High-voltage precautions
The vehicle has high voltage DC
and AC systems as well as a 12-
volt system.
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 volt-
age 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 temperature, and always
obey the warning labels
attached to the vehicle.

WARNING
●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)
contacting the ground, electric-
ity generated by the operation of
the motor may cause a fire to
occur depending on the nature
of the damage or malfunction.
(  P.507)
●Carefully inspect the ground
under the vehicle. If leaked liq-
uid (other than water from the
air conditioning) is found on the
ground, the traction battery may
have been damaged. Leave the
vehicle as soon as possible.
In addition, contact your Toyota
dealer with regard to the leak-
age found on the ground.
Even in the event of a minor
accident, the traction battery
and surrounding parts may be
damaged. In case of an acci-
dent, have the traction battery
inspected at a Toyota dealer.
■Traction battery
●Your vehicle contains a sealed
lithium-ion battery.
●Never resell, hand over or mod-
ify the traction battery. To pre-
vent accidents, traction
batteries that have been
removed from a disposed vehi-
cle are collected through your
Toyota dealer. Do not dispose of
the battery 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 hazardous 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
battery electric vehicle. If the
traction battery is used outside
of your vehicle or modified in
any way, accidents such as
electric shock, heat generation,
smoke generation, an explo-
sion and electrolyte leakage
may occur. When reselling or
handing over your vehicle, the
possibility of an accident is
extremely high because the per-
son receiving the vehicle may
not be aware of the dangers
from these modifications.
●If your vehicle is disposed of
without the traction battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the traction bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the traction bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
●For information about traction
battery collection locations, con-
tact information, or the recycling
process, contact your Toyota
dealer.

battery cannot be charged. Also,
when using the air conditioning
system, etc., the traction battery
electricity is consumed.
(P.237)
Repeated acceleration and
deceleration due to traffic con-
gestion, long waits at traffic
lights, and driving on steep
inclines will lead to poor electric-
ity consumption. In order to
avoid those situations as much
as possible, check traffic reports
before leaving. If the vehicle is
driven in traffic congestion, gen-
tly release the brake pedal to
allow the vehicle to move for-
ward slightly, avoid overuse of
the accelerator pedal. Doing so
can help minimize unnecessary
electricity consumption.
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 simi-
lar, allow plenty of time to release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.

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 recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce electric-
ity consumption as well.
In winter: Exce ssive or unneces-
sary heating should be avoided.
Also, electricity consumption can
be improved by avoiding overuse of
the heater.
 When using the Remote Air
Conditioning System
( P.409) while the AC
charging cable is connected
to the vehicle, electricity con-
sumption immediately after
starting off will be reduced
because air conditioning is
operated mainly using elec-
tricity from an external power
source.
Make sure to check the tire infla-
tion pressure frequently.
