: This button is intended for communica-

tion with the eCall system operator.
Other SOS buttons available in other
systems of a motor vehicle do not relate
to the device and are not intended for
communication with the eCall system

operator.

Automatic Emergency Calls

If any airbag deploys, the system is
designed to automatically call the
eCall control center.

The answering

operator receives the vehicle’s loca-
tion, the time of the incident and the
vehicle VIN, and attempts to speak
with the vehicle occupants to assess
the situation. If the occupants are
unable to communicate, the operator
automatically treats the call as an
emergency and contacts the nearest
emergency services provider (112 sys-
tem etc.) to describe the situation and
request that assistance be sent to the
location.

: In some cases, the call cannot be made.

Manual Emergency Calls

In the event of an emergency, press the
“SOS” button to call the eCall control
center.

The answering operator will

determine your vehicle’s location,
assess the situation, and dispatch the
necessary assistance required.
Make sure to open the cover before
pressing the “SOS” button.

eCall

eCall is a telematics service that
uses Global Navigation Satellite
System (GNSS) data and embed-
ded cellular technology to enable
the following emergency calls to be
made: Automatic emergency calls
(Automatic Collision Notification)
and manual emergency calls (by
pressing the “SOS” button). This
service is required by European
Union Regulations.

Electric Vehicle system features

Electric vehicles are considerably different from conventional vehicles.
They use electricity charged in a traction battery, to drive the electric motor.
Since electric vehicles are driven using electricity, they do not emit any emis-
sions such as CO

(Carbon Dioxide) and NOx (Nitrogen Oxides). Electric

vehicles are environmentally friendly vehicles.

When braking (regenerative brak-
ing)

The electric motor (traction motor)
charges the traction battery.
The driving range can be extended by
actively using this regenerative braking
to store electricity in the traction bat-
tery.

The electric vehicle is driven using
electricity, received an external power
source, that is stored in the traction
battery. Not only public charging sta-
tions, but also household outlets can be
used for charging. Procedures are dif-
ferent from refueling a conventional
vehicle. Therefore, make sure to read
the following thoroughly.

Regenerative braking

In the following situations, kinetic energy is

converted to electric energy and decelera-

tion force can be obtained in conjunction

with the recharging of the traction battery.

The accelerator pedal is released while

driving with the shift position in D or B.

The brake pedal is depressed while driv-

ing with the shift position in D or B.

Charging the 12-volt battery

The 12-volt battery is charged from the

traction battery when the EV system is

operated or while the traction battery is

being charged.
If the vehicle has not been used for a long

time, the 12-volt battery may become low

due to self-discharge. If this occurs, follow

the correct procedures. (



P.461)

When not using the vehicle for an

extended period of time

When the vehicle will not be used for an

extended period of time, charge the trac-

tion battery once a month.

This protects the traction battery from

extreme voltage decline due to self dis-

charging.

To prevent the 12-volt battery from being

discharged, do not leave the charging

port lid open or the charging cable con-

nected to the vehicle.

Charging the traction battery

Be sure to maintain the traction battery

charge level suitable for your driving needs.
If the traction battery fully discharges, 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 dis-

play. (



P.436)

If the traction battery is completely dis-

charged, the EV system cannot be

started and driving will not be possible.

When the traction battery becomes low,

charge it as soon as possible.

2-1. Electric vehicle system

Sounds and vibrations specific to an

electric vehicle

Because there is no engine sound or vibra-

tion, it is easy to mistake the electric vehicle

for being off when it is actually still running,

as indicated by the “READY” indicator

being illuminated. For 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/or

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.

Electrical relay sounds may be heard

from the motor compartment when the

EV system starts or stops.

Relay operating sounds such as a snap or

soft clank will be emitted from the trac-

tion battery in the following situations:

• When the EV system is started or

stopped

• When charging starts or completes

• When the vehicle is driven the first time

after the traction battery has been

charged using DC charging

Sounds may be heard due to regenera-

tive braking when the brake pedal is

depressed or as the accelerator pedal is

released.

Cooling fan operating sounds from the

radiator and/or traction battery.

The operation sound of the air condition-

ing system (air conditioning compressor,

blower motor).

Maintenance, repair, recycling, and dis-

posal

Contact any authorized Lexus retailer or

Lexus authorized repairer, or any reliable

repairer regarding maintenance, repair,

recycling and disposal. Do not dispose of

the vehicle yourself.

A sound which changes in accordance
with the driving speed, will be played in

Electromagnetic waves

High-voltage parts and cables on the

electric vehicles incorporate electro-

magnetic shielding, and therefore emit

approximately the same amount of elec-

tromagnetic waves as conventional gaso-

line-powered vehicles or home

electronic appliances.

Your vehicle may cause sound interfer-

ence in some third party-produced radio

parts.

Traction battery (Lithium-ion battery)

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 rechargeable batter-

ies. The extent at which capacity reduces

changes drastically depending on the envi-

ronment (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

battery, and is not a malfunction. Also, even

though the driving range decreases when

the traction battery capacity reduces, vehi-

cle performance does not significantly

become worse. In order to reduce the pos-

sibility of the capacity reducing, follow the

directions listed on P.115, “Capacity reduc-

tion 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 temperature of the traction battery

increases due to the outside temperature

increasing, 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 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 voltage parts, cables

(orange) or their connectors.

The EV system will become hot after

starting as the system uses high volt-

age. Be careful of both the high volt-

age and the high temperature, and

always obey the warning labels

attached to the vehicle.

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.

WARNING

Road accident cautions

Observe the following precautions to

reduce the risk of death or serious injury:

Stop the vehicle in a safe place to pre-

vent subsequent accidents. While

depressing the brake pedal, apply the

parking brake and shift the shift posi-

tion 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 liq-

uid 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 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 trac-

tion battery, do not approach the vehi-

cle.

Even in the unlikely event that the trac-

tion battery has been damaged, the

internal construction of the battery will

prevent a large amount of electrolyte

from leaking out. However, if electro-

lyte 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 electrolyte.

The electrolyte may ignite and cause a

fire.

If a fire occurs in the electric vehicle,

leave the vehicle as soon as possible.

Never use a fire extinguisher that is not

meant for electrical 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 raised. If the vehicle is

towed with the front wheels which are

connected to the electric motor (trac-

tion motor) contacting the ground,

electricity generated by the operation

of the motor may cause a fire to occur

depending on the nature of the dam-

age or malfunction. (



P.427)

Carefully inspect the ground under the

vehicle. If leaked liquid (other than

water from the air conditioning) is

found on the ground, the traction bat-

tery may have been damaged. Leave

the vehicle as soon as possible.

In addition, contact any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer with

regard to the leakage found on the

ground.

Traction battery

Your vehicle contains a sealed lithium-

ion battery.

Never resell, hand over or modify the

traction battery. To prevent accidents,

traction batteries that have been

removed from a disposed vehicle are

collected through any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. Do

not dispose of the battery yourself.

Unless the battery is properly col-

lected, the following may occur, result-

ing in death or serious injury:

• The traction battery may be illegally

disposed of or dumped, and it is haz-

ardous to the environment or some-

one may touch a high voltage part,

resulting in an electric shock.

2-1. Electric vehicle system

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 sys-
tem activates, your vehicle will not
restart. To restart the EV system, con-
tact any authorized Lexus retailer or
Lexus authorized repairer, or any reli-
able repairer.

A message is automatically displayed
when a malfunction occurs in the EV
system or an improper operation is
attempted.

WARNING

• The traction battery is intended to be

used exclusively with your 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 gener-

ation, an explosion and electrolyte

leakage may occur. When reselling or

handing over your vehicle, the possi-

bility of an accident is extremely high

because the person receiving the vehi-

cle may not be aware of these dangers.

If your vehicle is disposed of without

the traction battery having 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 any autho-

rized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer or a qualified service 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 battery

collection locations, contact informa-

tion, or the recycling process, contact

any authorized Lexus retailer or Lexus

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 people and

vehicles in the area may not be aware

of the vehicle starting off or approach-

ing them, so take extra care while driv-

ing. Therefore, take extra care while

driving even if the Acoustic Vehicle

Alerting System is active.

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 vehi-

cle. If there is damage to the traction

battery or liquid leakage, it may lead to

a vehicle fire, etc. Do not touch the

vehicle and immediately contact any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

Modifications

Do not modify to 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 dam-

aged, a vehicle fire may occur, possibly

resulting in death or serious injury.

When the traction battery is completely

discharged

When the EV system cannot be started due

to the traction battery being completely dis-

charged, restart the system after AC

charging or DC charging. When charging,

it is recommended to charge the traction

battery until the traction battery charge

warning light turns off in order to ensure

sufficient driving distance.
Also, in the completely discharged state,

DC charging can not be performed with

the power switch ON, charge the traction

battery with the power switch OFF.

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 con-
sumption. In the N, the traction battery
cannot be charged. Also, when using
the air conditioning system, etc., the
traction battery electricity is con-
sumed. (

Electric Vehicle driving tips

Unlike the conventional vehicles,
the electricity consumption effi-
ciency of electric vehicles will
decline if they continue driving on
highways (or freeways) or at high
average speeds, causing the possi-
ble driving distance to reduce.
Therefore, if the remaining charge
of the traction battery is low, avoid
relying on the displayed possible
driving distance too much as well as
driving on highways (or freeways).
Driving the vehicle at moderate
speeds, the traction battery’s elec-
tricity consumption can be con-
trolled.
The following driving tips will con-
tribute to reduction in the battery
consumption and increase in the
driving range.

Shift position operation

2-1. Electric vehicle system

Repeated acceleration and decelera-
tion due to traffic congestion, 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 conges-
tion, gently release the brake pedal to
allow the vehicle to move forward
slightly, avoid overuse of the accelera-
tor pedal. Doing so can help minimize
unnecessary electricity consumption.

Keeping the EV System Indicator
within Eco area can help minimize con-
sumption of the traction battery, allow-
ing the vehicle to drive in an Eco-
friendly manner. (



P.162, 172)

Make sure to operate the brakes gen-
tly 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 accelerator and
gently 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 con-
sumption.

In summer: When the ambient tempera-
ture 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 heat-
ing should be avoided. Also, electricity
consumption can be improved by avoiding
overuse of the heater.



Lexus Climate Concierge allows
automatic air-conditioning control
to maintain a comfortable condition,
helping minimize unnecessary elec-
tricity consumption. (



P.344)



When using the Remote Air Condi-
tioning System (



P.355) while the

AC charging cable is connected to
the vehicle, electricity consumption
immediately after starting off will be
reduced because air conditioning is
operated mainly using electricity
from an external power source.



When setting the charging sched-
ule, selecting “Departure” charging
mode and setting “Climate Prep” to
“On”, electricity consumption
immediately after starting off can be
reduced because air conditioning is
operated to adjust the cabin tem-
perature in advance and match it
with the departure time. (

Make sure to check the tire inflation
pressure frequently. Improper tire
inflation pressure can cause poor elec-
tricity consumption.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads will lead to poor electricity con-
sumption. Use tires that are appropri-
ate 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 provided

charge of the traction battery, the state
of the traction battery, the outside tem-
perature, etc. and is displayed on the

P.165)

When the outside temperature is low,
the traction battery output may be
decreased, causing the possible driv-
ing distance to be shorter. However,
this is not a malfunction. Charge the
traction battery earlier than usual.

Possible driving distance varies signifi-
cantly depending on how the vehicle is
driven, road conditions, the weather,
the outside temperature, usage condi-
tions of electrical components and the
number of occupants.
