Lexus ES300H (2024 year). Manual in english

Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find explanations for equipment not
installed on your vehicle and the illus-
trations used may differ from your vehi-
cle.
All specifications provided in this man-
ual are current at the time of printing.
Over time, your vehicle may receive
updates that modify the vehicle and
make material in this manual incom-
plete and/or inaccurate. Because of
Lexus’ interest in continual product
improvement, Lexus reserves the right
to make changes to this manual at any
time without notice.
If Lexus chooses to update the manual,
updated versions can be viewed by
selecting your vehicle by model and
year at the following URL or on your
mobile device if you have access to the

Approximately five hours after the
hybrid system is turned off, you may
hear sound coming from under the
vehicle for several minutes. This is the
sound of a fuel evaporation leakage
check and, it does not indicate a mal-
function.

A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance,
repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
Also, remodeling like this will have an
effect on advanced safety equipment
such as Lexus Safety System + 2.5 and
there is a danger that it will not work
properly or the danger that it may work
in situations where it should not be
working.

Installing electronic devices and radios
increases the risk of cyber attacks
through the installed parts, which may
lead to unexpected accidents and
leakage of personal information. Lexus
does not make any guarantees for

tion of a mobile two-way radio system.
High voltage parts and cables on the
Hybrid Electric Vehicles emit approxi-
mately the same amount of electro-
magnetic waves as the conventional
gasoline powered vehicles or home
electronic appliances despite of their
electromagnetic shielding.
Unwanted noise may occur in the
reception of the mobile two-way radio.

The vehicle is equipped with sophisti-
cated computers that will record cer-
tain data, such as:
• Engine speed/Electric motor speed

(traction motor speed)

• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving

assist systems

• Images from the cameras

Your vehicle is equipped with cam-
eras. Contact your Lexus dealer for
the location of recording cameras

The recorded data varies according to
the vehicle grade level and options
with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.



Data Transmission

Your vehicle may transmit the data
recorded in these computers to Lexus
without notification to you.



Data usage

Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.
Lexus will not disclose the recorded data
to a third party except:
• With the consent of the vehicle owner or

with the consent of the lessee if the vehi-
cle is leased

• In response to an official request by the

police, a court of law or a government
agency

To learn more about the vehicle
data collected, used and shared by
Lexus, please visit

This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose of an EDR is to record, in certain
crash or near crash-like situations,
such as an air bag deployment or hit-
ting a road obstacle, data that will assist
in understanding how a vehicle’s sys-
tems performed. The EDR is designed
to record data related to vehicle
dynamics and safety systems for a
short period of time, typically 30 sec-
onds or less.

The EDR in this vehicle is designed to
record such data as:



How various systems in your vehicle
were operating;



Whether or not the driver and pas-
senger safety belts were buck-
led/fastened;



How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,



How fast the vehicle was traveling.

These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by
your vehicle only if a non-trivial crash
situation occurs; no data are recorded
by the EDR under normal driving con-
ditions and no personal data (e.g.,
name, gender, age, and crash location)
are recorded. However, other parties,
such as law enforcement, could com-
bine the EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle man-
ufacturer, other parties, such as law
enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.



Disclosure of the EDR data

Lexus will not disclose the data recorded in
an EDR to a third party except when:

Usage of data collected through
Connected service (U.S.main-
land only)

Event data recorder

• An agreement from the vehicle’s owner

(or the lessee for a leased vehicle) is
obtained

• In response to an official request by the

police, a court of law or a government
agency

• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle

safety performance

• Disclose the data to a third party for

research purposes without disclosing
information about the specific vehicle or
vehicle owner

The SRS airbag and seat belt preten-
sioner devices in your Lexus contain
explosive chemicals. If the vehicle is
scrapped with the airbags and seat belt
pretensioners not deployed, this may
cause an accident such as fire. Be sure
to have the systems of the SRS airbag
and seat belt pretensioner removed
and disposed of by a qualified service
shop or by your Lexus dealer before
you scrap your vehicle.

Special handling may apply, See

Your vehicle has components that may
contain perchlorate. These compo-
nents may include the airbags, seat belt
pretensioners, wireless remote control
batteries, and the batteries in the tire
pressure warning valve and transmit-

ters.

WARNING

■

General precautions while driving

Driving under the influence: Never drive

your vehicle when under the influence of

alcohol or drugs that have impaired your

ability to operate your vehicle. Alcohol

and certain drugs delay reaction time,

impair judgment and reduce coordina-

tion, which could lead to an accident that

could result in death or serious injury.
Defensive driving: Always drive defen-

sively. Anticipate mistakes that other

drivers or pedestrians might make and

be ready to avoid accidents.
Driver distraction: Always give your full

attention to driving. Anything that dis-

tracts the driver, such as adjusting con-

trols, talking on a cellular phone or

reading can result in a collision with

resulting death or serious injury to you,

your occupants or others.

■

General precaution regarding chil-

dren’s safety

Never leave children unattended in the

vehicle, and never allow children to have

or use the key.
Children may be able to start the vehicle

or shift the vehicle into neutral. There is

also a danger that children may injure

themselves by playing with the windows,

the moon roof, or other features of the

vehicle. In addition, heat build-up or

extremely cold temperatures inside the

vehicle can be fatal to children.

1-1.For safe use

Use only floor mats designed specifi-
cally for vehicles of the same model
and model year as your vehicle. Fix
them securely in place onto the carpet.

Insert the retaining hooks (clips)
into the floor mat eyelets.

Turn the upper knob of each retain-
ing hook (clip) to secure the floor
mats in place.

Always align the

marks

The shape of the retaining hooks (clips)

may differ from that shown in the illustra-

tion.

Before driving

Observe the following before start-
ing off in the vehicle to ensure
safety of driving.

Installing floor mats

WARNING

Observe the following precautions.

Failure to do so may cause the driver’s

floor mat to slip, possibly interfering with

the pedals while driving. An unexpect-

edly high speed may result or it may

become difficult to stop the vehicle. This

could lead to an accident, resulting in

death or serious injury.

■

When installing the driver’s floor mat

●

Do not use floor mats designed for

other models or different model year

vehicles, even if they are Lexus Genu-

ine floor mats.

●

Only use floor mats designed for the

driver’s seat.

●

Always install the floor mat securely

using the retaining hooks (clips) pro-

vided.

●

Do not use two or more floor mats on

top of each other.

●

Do not place the floor mat bottom-

side up or upside-down.

■

Before driving

●

Check that the floor mat is securely

fixed in the correct place with all the

provided retaining hooks (clips). Be

especially careful to perform this

check after cleaning the floor.

●

With the hybrid system stopped and

the shift lever in P, fully depress each

pedal to the floor to make sure it does

not interfere with the floor mat.

1-1. For safe use

For safety and security

Adjust the angle of the seatback so
that you are sitting straight up and
so that you do not have to lean for-
ward to steer. (



P.120)

Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the
elbow when gripping the steering
wheel. (



P.120)

Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
(



P.124)

Wear the seat belt correctly.
(



P.25)

Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (



P.25)

Use a child restraint system appropri-
ate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. (

P.127, 128)

For safe driving

For safe driving, adjust the seat and
mirror to an appropriate position
before driving.

Correct driving posture

WARNING

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

Do not adjust the position of the

driver’s seat while driving.

Doing so could cause the driver to lose

control of the vehicle.

●

Do not place a cushion between the

driver or passenger and the seatback.

A cushion may prevent correct pos-

ture from being achieved, and reduce

the effectiveness of the seat belt and

head restraint.

●

Do not place anything under the front

seats.

Objects placed under the front seats

may become jammed in the seat

tracks and stop the seat from locking

in place. This may lead to an accident

and the adjustment mechanism may

also be damaged.

●

Always observe the legal speed limit

when driving on public roads.

●

When driving over long distances,

take regular breaks before you start to

feel tired.

Also, if you feel tired or sleepy while

driving, do not force yourself to con-

tinue driving and take a break immedi-

ately.

Correct use of the seat belts

1-1. For safe use

Seat belts

Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle.

WARNING

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking, sudden swerving or an

accident.

Failure to do so may cause death or seri-

ous injury.

■

Wearing a seat belt

●

Ensure that all passengers wear a seat

belt.

●

Always wear a seat belt properly.

●

Each seat belt should be used by one

person only. Do not use a seat belt for

more than one person at once, includ-

ing children.

●

Lexus recommends that children be

seated in the rear seat and always use

a seat belt and/or an appropriate child

restraint system.

●

To achieve a proper seating position,

do not recline the seat more than nec-

essary. The seat belt is most effective

when the occupants are sitting up

straight and well back in the seats.

●

Do not wear the shoulder belt under

your arm.

●

Always wear your seat belt low and

snug across your hips.

■

Pregnant women

Obtain medical advice and wear the seat

belt in the proper way. (



P.25)

Women who are pregnant should posi-

tion the lap belt as low as possible over

the hips in the same manner as other

occupants, extending the shoulder belt

completely over the shoulder and avoid-

ing belt contact with the rounding of the

abdominal area.
If the seat belt is not worn properly, not

only the pregnant woman, but also the

fetus could suffer death or serious injury

as a result of sudden braking or a colli-

sion.

■

People suffering illness

Obtain medical advice and wear the seat

belt in the proper way. (



P.25)

■

Seat belt damage and wear

●

Do not damage the seat belts by allow-

ing the belt, plate, or buckle to be

jammed in the door.

●

Inspect the seat belt system periodi-

cally. Check for cuts, fraying, and

loose parts. Do not use a damaged

seat belt until it is replaced. Damaged

seat belts cannot protect an occupant

from death or serious injury.

1-1. For safe use

For safety and security



Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.



Position the lap belt as low as possi-
ble over the hips.



Adjust the position of the seatback.
Sit up straight and well back in the
seat.



Do not twist the seat belt.

■

Child seat belt usage

The seat belts of your vehicle were princi-

pally designed for persons of adult size.

●

Use a child restraint system appropriate

for the child, until the child becomes large

enough to properly wear the vehicle’s

seat belt. (



P.43)

●

When the child becomes large enough to

properly wear the vehicle’s seat belt, fol-

low the instructions regarding seat belt

usage. (



P.24)

■

Seat belt extender

If your seat belts cannot be fastened

securely because they are not long enough,

a personalized seat belt extender is avail-

able from your Lexus dealer free of charge.

■

Rear seat belt

Use the seat belt after passing it through the

guide if the seat belt comes free from the

guide.

WARNING

●

Ensure that the belt and plate are

locked and the belt is not twisted.

If the seat belt does not function cor-

rectly, immediately contact your Lexus

dealer.

●

Replace the seat assembly, including

the belts, if your vehicle has been

involved in a serious accident, even if

there is no obvious damage.

●

Do not attempt to install, remove,

modify, disassemble or dispose of the

seat belts. Have any necessary repairs

carried out by your Lexus dealer. Inap-

propriate handling may lead to incor-

rect operation.

Correct use of the seat belts

WARNING

■

Using a seat belt extender

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking, sudden swerving or an

accident.

Failure to do so may cause death or seri-

ous injury.

●

Do not wear the seat belt extender if

you can fasten the seat belt without the

extender.

1-1. For safe use

To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.

To release the seat belt, press the
release button

■

Emergency locking retractor (ELR)

The retractor will lock the belt during a sud-

den stop or on impact. It may also lock if you

lean forward too quickly. A slow, easy

motion will allow the belt to extend so that

you can move around fully.

■

Automatic locking retractor (ALR)

When a passenger’s shoulder belt is com-

pletely extended and then retracted even

slightly, the belt is locked in that position

and cannot be extended. This feature is

used to hold a child restraint system (CRS)

firmly. To free the belt again, fully retract the

belt and then pull the belt out once more.

Push the seat belt shoulder anchor
down while pressing the release
button .

Push the seat belt shoulder anchor
up while pressing the release but-
ton .

Move the height adjuster up and down as
needed until you hear a click.

WARNING

●

Do not use the seat belt extender

when installing a child restraint system

because the belt will not securely hold

the child restraint system, increasing

the risk of death or serious injury in the

event of an accident.

●

The personalized extender may not be

safe on another vehicle, when used by

another person, or at a different seat-

ing position other than the one origi-

nally intended.

NOTICE

■

When using a seat belt extender

When releasing the seat belt, press on

the buckle release button on the

extender, not on the seat belt.

This helps prevent damage to the vehicle

interior and the extender itself.

WARNING

■

Adjustable shoulder anchor

Always make sure the shoulder belt is

positioned across the center of your

shoulder. The belt should be kept away

from your neck, but not falling off your

shoulder. Failure to do so could reduce

the amount of protection in an accident

and cause death or serious injuries in the

event of a sudden stop, sudden swerve

or accident.

1-1. For safe use

For safety and security

The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.

The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.

■

Replacing the belt after the preten-

sioner has been activated

If the vehicle is involved in multiple colli-

sions, the pretensioner will activate for the

first collision, but will not activate for the

second or subsequent collisions.

Seat belt pretensioners (front
and outboard rear seats)

WARNING

■

Seat belt pretensioners

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking, sudden swerving or an

accident.

Failure to do so may cause death or seri-

ous injury.

●

Do not place anything, such as a cush-

ion, on the front passenger’s seat.

Doing so will disperse the passenger’s

weight, which prevents the sensor

from detecting the passenger’s weight

properly. As a result, the seat belt pre-

tensioner for the front passenger’s seat

may not activate in the event of a colli-

sion.

●

If the pretensioner has activated, the

SRS warning light will come on. In that

case, the seat belt cannot be used

again and must be replaced at your

Lexus dealer.

Front impact sensors

Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system components diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising etc., may

be sustained from SRS airbags, due to the

extremely high speed deployment (infla-

tion) by hot gases.

●

A loud noise and white powder will be

emitted.

●

Parts of the airbag module (steering

wheel hub, airbag cover and inflator) as

well as the front seats, parts of the front

and rear pillars, and roof side rails, may

be hot for several minutes. The airbag

itself may also be hot.

●

The windshield may crack.

●

The hybrid system will be stopped and

fuel supply to the engine will be stopped.

For Safety Connect subscribers, if any of

the following situations occur, the system

is designed to send an emergency call to

the response center, notifying them of the

vehicle’s location (without needing to

push the “SOS” button) and an agent will

attempt to speak with the occupants to

ascertain the level of emergency and

assistance required. If the occupants are

unable to communicate, the agent auto-

matically treats the call as an emergency

and helps to dispatch the necessary

emergency services. (

• An SRS airbag is deployed.

• A seat belt pretensioner is activated.

• The vehicle is involved in a severe rear-

end collision.

■

SRS airbag deployment conditions (SRS

front airbags)

●

The SRS front airbags will deploy in the

event of an impact that exceeds the set

threshold level (the level of force corre-

sponding to an approximately 12 - 18

mph [20 - 30 km/h] frontal collision with

a fixed wall that does not move or

deform).

However, this threshold velocity will be

considerably higher in the following situ-

ations:

• If the vehicle strikes an object, such as a

parked vehicle or sign pole, which can

move or deform on impact

• If the vehicle is involved in an underride

collision, such as a collision in which the

front of the vehicle “underrides”, or goes

under, the bed of a truck

●

Depending on the type of collision, it is

possible that only the seat belt preten-

sioners will activate.

●

The SRS front airbags for the front pas-

senger will not activate if there is no pas-

senger sitting in the front passenger seat.

However, the SRS front airbags for the

front passenger may deploy if luggage is

put in the seat, even if the seat is unoccu-

pied.

■

SRS airbag deployment conditions (SRS

side and curtain shield airbags)

●

The SRS side and curtain shield airbags

will deploy in the event of an impact that

exceeds the set threshold level (the level

of force corresponding to the impact

force produced by an approximately

3300 lb. [1500 kg] vehicle colliding with

the vehicle cabin from a direction per-

pendicular to the vehicle orientation at an

approximate speed of 12 - 18 mph [20 -

30 km/h]).

●

Both SRS curtain shield airbags will

deploy in the event of a side collision on

either side.

●

Both SRS curtain shield airbags will

deploy in the event of vehicle rollover.

●

Both SRS curtain shield airbags may also

deploy in the event of a severe frontal

collision.

■

Conditions under which the SRS air-

bags may deploy (inflate), other than a

collision

The SRS front airbags and SRS curtain

shield airbags may also deploy if a serious

impact occurs to the underside of your

vehicle. Some examples are shown in the

illustration.

●

Hitting a curb, edge of pavement or hard

surface

●

Falling into or jumping over a deep hole

●

Landing hard or falling

The SRS curtain shield airbags may also

deploy under the situations shown in the

illustration.

●

The angle of vehicle tip-up is marginal.

●

The vehicle skids and hits a curb stone.

■

Types of collisions that may not deploy

the SRS airbags (SRS front airbags)

The SRS front airbags do not generally

inflate if the vehicle is involved in a side or

rear collision, if it rolls over, or if it is involved

in a low-speed frontal collision. But, when-

ever a collision of any type causes sufficient

forward deceleration of the vehicle, deploy-

ment of the SRS front airbags may occur.

●

Collision from the side

●

Collision from the rear

●

Vehicle rollover

■

Types of collisions that may not deploy

the SRS airbags (SRS side and curtain

shield airbags)

The SRS side and curtain shield airbags

may not activate if the vehicle is subjected

to a collision from the side at certain angles,

or a collision to the side of the vehicle body

other than the passenger compartment.

●

Collision from the side to the vehicle

body other than the passenger compart-

ment

●

Collision from the side at an angle

1-1. For safe use

The SRS side airbags do not generally

inflate if the vehicle is involved in a frontal or

rear collision, if it rolls over, or if it is involved

in a low-speed side collision.

●

Collision from the front

●

Collision from the rear

●

Vehicle rollover

The SRS curtain shield airbags do not gen-

erally inflate if the vehicle is involved in a

rear collision, if it pitches end over end, or if

it is involved in a low-speed side or low-

speed frontal collision.

●

Collision from the rear

●

Pitching end over end

■

area is damaged, deformed or has had a

hole made in it, or the vehicle was

involved in an accident that was not

severe enough to cause the SRS side and

curtain shield airbags to inflate.

●

The pad section of the steering wheel,

dashboard near the front passenger air-

bag or lower portion of the instrument

panel is scratched, cracked, or otherwise

damaged.

●

The surface of the seats with the SRS side
