■

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.

●

The brake pedal is depressed while driv-

ing with the shift position in D.

■

Charging the 12-volt battery

The 12-volt battery is charged from the trac-

tion battery when the EV system is oper-

ated 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.526)

■

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.

●

When the vehicle will not be used for an

extended period of time, the 12-volt bat-

tery will be charged from the traction bat-

tery to reduce the risk of the 12-volt

battery discharged. In this case, the cool-

ing fan may operate, however it is not a

malfunction.

●

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.473)

●

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.

■

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 vibra-

tions 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 luggage com-

partment.

●

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.

●

The operation sound of the air condition-

ing system (air conditioning compressor,

blower motor).

■

Maintenance, repair, recycling, and dis-

posal

Contact your Lexus dealer regarding main-

tenance, 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
order to warn people nearby of the
vehicle’s approach. This sound may be
heard inside the vehicle. The sound will
stop when the vehicle speed exceeds
approximately 22 mph (37 km/h).

■

Electromagnetic waves

●

High-voltage parts and cables on the bat-

tery electric vehicles incorporate elec-

tro-magnetic shielding, and therefore

emit approximately the same amount of

electromagnetic waves as conventional

gasoline-powered vehicles or home elec-

tronic 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

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 pos-

sibility of the capacity reducing, follow the

directions listed on P.48, “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 -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 temperature 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 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.

■

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.

1-2. Important points for the EV system

WARNING

●

If electric wires are exposed inside or

outside your vehicle, an electric shock

may occur. Never touch exposed elec-

tric wires.

●

Do not touch the traction battery if liq-

uid is leaking from or adhered to it. If

electrolyte (Organic Carbon-

ate-based electrolyte) from the trac-

tion 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 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 battery 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 dangerous.

●

If your vehicle needs to be towed, be

sure to transport the vehicle with the

four wheels raised. If the vehicle is

towed with the wheels which are con-

nected to the electric motor (traction

motor) contacting the ground, elec-

tricity generated by the operation of

the motor may cause a fire to occur

depending on the nature of the dam-

age or malfunction. (



P.549)

●

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 your Lexus dealer

with regard to the leakage 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 accident,

have the traction battery inspected at

your Lexus dealer.

■

Traction battery

●

Your vehicle contains a sealed lith-

ium-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 your Lexus dealer.

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:

• 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 mod-

ified in any way, accidents such as

electric shock, heat generation, smoke

generation, an explosion and electro-

lyte leakage may occur. When resell-

ing or handing over your vehicle, the

possibility of an accident is extremely

high because the person receiving the

vehicle may not be aware of the dan-

gers from these modifications.

1-2. Important points for the EV system

fore
driving

P.471

A message is automatically displayed
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 instructions.
(

P.483)

■

If a warning light comes on, a warning

message is displayed, or the 12-volt bat-

tery 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 your Lexus dealer.

WARNING

●

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 your Lexus

dealer 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

your Lexus dealer.

■

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 your

Lexus dealer.

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 trac-

tion battery inspected at your Lexus

dealer.

■

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 bat-

tery is damaged, a vehicle fire may occur,

possibly resulting in death or serious

injury.

Emergency shut off system

Warning message

1-2. Important points for the EV system

■

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.

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. (



P.145)

Battery Electric Vehicle driv-
ing tips

Unlike the conventional vehicles,
the electricity consumption effi-
ciency of battery electric vehicles
will decline if they continue driving
on highways (or freeways) or at
high average speeds, causing the
possible 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

1-2. Important points for the EV system

fore
driving

■

Eco drive mode

When using Eco drive mode, torque
generation is slower when stepping on
the accelerator pedal, air conditioning
operations (heating/cooling) are
restrained, and driving becomes suited
for improved electricity consump-
tion.(



P.192)

■

Range mode

When using range mode, the driving
controls is changed to those for
improved electric consumption, in
terms of the vehicle speed limits, the
maximum driving force limits, the opti-
mized front-rear allocation of the driv-
ing force, etc., along with turning off of
the air conditioning system (heat-
ing/cooling). In this mode, the driving
distance will be maximized. (



P.192)

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.

Make sure to operate the brakes gently
and a timely manner. A greater amount
of electrical energy can be regener-
ated 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. (

1-2. Important points for the EV system

Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor electric-
ity 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.

The value that sufficient driving perfor-
mance is provided, estimated from the
remaining charge of the traction bat-
tery, the state of the traction battery,
and the outside temperature, is dis-
played on the meter. (



P.241)

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.
Possible driving distance could be
extended if the followings are per-
formed:



Maintain a safe distance from the
vehicle in front and avoid unneces-
sary acceleration and deceleration
