Operation of this system is separated
into 4 control states. Through control
state “warning phase 1” and “warning

driver is aware and responsive while
outputting a warning and controlling

Emergency Driving Stop
System

Emergency Driving Stop System

The emergency driving stop system
is a system which automatically
decelerates and stops the vehicle
within its lane if the driver becomes
unable to continue driving the vehi-
cle, such as if they have suffered a
medical emergency, etc.

During LTA (Lane Tracing Assist)
control, if the system does not
detect driving operations, such as if
the driver is not holding the steer-
ing wheel, and determines the
driver is not responsive, the vehicle
will be decelerated and stopped
within its current lane to help avoid
a collision or reduce the impact of a
collision.

WARNING

■

For safe use

●

Driving safely is solely the responsibil-

ity of the driver. Pay careful attention to

the surrounding conditions in order to

ensure safe driving. The emergency

driving stop system is designed to pro-

vide support in an emergency where it

is difficult for the driver to continue

driving, such as if they have had a med-

ical emergency. It is not designed to

support driving while drowsy or in

poor physical health, or inattentive

driving.

●

Although the emergency driving stop

system is designed to decelerate the

vehicle within its lane to help avoid or

help reduce the impact of a collision if

the system determines that it is difficult

for the driver to continue driving, its

effectiveness may change according

to various conditions. Therefore, it may

not always be able to achieve the same

level of performance. Also, if the oper-

ating conditions are not met, this func-

tion will not operate.

●

After the emergency driving stop sys-

tem operates, if driving becomes pos-

sible again, immediately begin driving

again or, if necessary, park the vehicle

on the shoulder of the road and set a

warning reflector and flare to warn

other drivers of your stopped vehicle.

●

After this system operates, passengers

should attend to the driver as neces-

sary and take appropriate hazard pre-

vention measures, such as moving to a

place where safety can be ensured,

such as the shoulder of the road or

behind a guardrail.

●

This system detects the condition of

the driver through the operation of the

steering wheel. This system may oper-

ate if the driver is aware but intention-

ally and continuously does not operate

the vehicle. Also, the system may not

operate if it cannot determine that the

driver is not responsive, such as if they

are leaning on the steering wheel.

mines the driver is not responsive, it will
operate in control state “deceleration
stop phase” and “stop hold phase” and
decelerate and stop the vehicle. It will
then operate continuously in “stop hold
phase”.

■

Operating conditions

This system operates when all of the follow-

ing conditions are met:

●

When the LTA is on

●

When the vehicle speed is approximately

50 km/h (30 mph) or more

■

Operation cancelation conditions

In the following situations, system operation

will be canceled:

●

When LTA control has been canceled

(the LTA switch has been pressed, etc.)

●

When the dynamic radar cruise control

has been canceled

●

When driver operations are detected

(the steering wheel is held, the brake

pedal, accelerator pedal, parking brake,

LTA control when operation is canceled

When emergency driving stop system

operation is canceled, LTA control may also

be canceled.

If driving operations are not detected
after the hands off steering wheel
warning operates, a buzzer will sound

intermittently and a message will be
displayed to warn the driver, and the
system will judge if the driver is respon-
sive or not. If driving operations, such
as holding the steering wheel, are not
performed within a certain amount of
time, the system will enter warning
phase 2.
Depending on the type of detection of
the driver’s unresponsiveness, the sys-
tem may skip warning phase 1 and start
the control of warning phase 2.

After entering warning phase 2, a
buzzer will sound in short intervals and
a message will be displayed to warn the
driver, and the vehicle will slowly
decelerate. If driving operations, such
as holding the steering wheel, are not
performed within a certain amount of
time, the system will determine that the
driver is not responsive and enter the
deceleration stop phase.
The audio system will be muted until
the driver becomes responsive.
When the vehicle is decelerating, the
brake lights may illuminate, depending
on the road conditions, etc.
After the vehicle has decelerated a
certain amount, the emergency flash-
ers (hazard lights) will flash.

After the driver is judged as being not
responsive, a buzzer will sound contin-

vehicle is decelerating, the emergency
flashers (hazard lights) will flash to
warn other drivers of the emergency.

After the vehicle is stopped, the park-
ing brake will be applied automatically.
After entering the stop and hold phase,
the buzzer will continue sounding con-

Blind Spot Monitor

The blind spot monitor is a system
that uses rear side radar sensors
installed on the inner side of the
rear bumper on the left and right
side to assist the driver in confirm-
ing safety when changing lanes.

WARNING

■

Cautions regarding the use of the sys-

tem

●

The driver is solely responsible for safe

driving. Always drive safely, taking

care to observe your surroundings.

●

The blind spot monitor is a supplemen-

tary function which alerts the driver

that a vehicle is in a blind spot of the

outside rear view mirrors or is

approaching rapidly from behind into a

blind spot. Do not overly rely on the

blind spot monitor. As the function

cannot judge if it is safe to change

lanes, over reliance could lead to an

accident resulting in death or serious

injury. As the system may not function

correctly under certain conditions, the

driver’s own visual confirmation of

safety is necessary.

Safe Exit Assist

The safe exit assist (with door open-
ing control) is a system that uses
rear side radar sensors installed on
the inner side of the rear bumper to
help occupants judge if an
approaching vehicle or bicycle may
collide with a door when exiting or
cancel opening of a door, to help
reduce the possibility of a collision.

WARNING

■

Cautions regarding the use of the sys-

tem

●

The driver is solely responsible for safe

driving. Always drive safely, taking

care to observe your surroundings.

●

The safe exit assist is a supplementary

system that, when the vehicle is

stopped, informs occupants of the

existence of approaching vehicles and

bicycles. As this system alone cannot

be used to judge safety, over-reliance

on this system may lead to an accident

resulting in death or serious injury.

Cautions regarding the use of the sys-

tem

There is a limit to the degree of recogni-

tion accuracy and control performance

that this system can provide, do not

overly rely on this system. The driver is

always responsible for paying attention

to the vehicle’ surroundings and driving

safely.

■

To ensure the system can operate

properly

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not damage the sensors, and

always keep them clean.

●

Do not attach a sticker or install an

electronic component, such as a

backlit license plate (especially fluo-

rescent type), fog lights, fender pole or

wireless antenna near a radar sensor.

●

Do not subject the surrounding area of

the sensor to a strong impact. If sub-

jected to an impact, have the vehicle

inspected by any authorized Lexus

retailer or Lexus authorized repairer,

or any reliable repairer. If the front or

rear bumper needs to be

removed/installed or replaced, con-

tact any authorized Lexus retailer or

Lexus authorized repairer, or any relia-

ble repairer.

●

Do not modify, disassemble or paint

the sensors.

●

Do not attach a license plate cover.

●

Keep your tires properly inflated.

■

When to disable the function

In the following situations, disable the

function as it may operate even though

there is no possibility of a collision.

●

Failing to observe the warnings above.

●

A non-genuine Lexus suspension

(lowered suspension, etc.) is installed.

■

Notes when washing the vehicle

Do not apply intensive bursts of water or

steam to the sensor area.

Doing so may result in the sensor mal-

functioning.

●

When using a high pressure washer to

wash the vehicle, do not spray the sen-

sors directly, as doing so may cause a

sensor to malfunction.

●

When using steam to clean the vehicle,

do not direct steam too close to the

sensors as doing so may cause a sen-

sor to malfunction.

system will return to normal.
If a warning message is displayed even if the

sensor is clean, there may be a sensor mal-

function. Have the vehicle inspected by any

authorized Lexus retailer or Lexus author-

ized repairer, or any reliable repairer.

■

Sensor detection information

●

The sensor’s detection areas are limited

to the areas around the vehicle’ front and

rear bumpers.

●

The following situations may occur dur-

ing use.

• Depending on the shape of the object

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• Detection may be impossible if static

objects draw too close to the sensor.

• There will be a short delay between static

object detection and display (warning

buzzer sounds). Even at low speeds,

there is a possibility that the object will

come within 30 cm (1.0 ft.) before the

display is shown and the warning buzzer

sounds.

• It might be difficult to hear the buzzer due

to the volume of the audio system or air

flow noise of the air conditioning system.

• It may be difficult to hear the sound of this

system due to the buzzers of other sys-

tems.

■

Objects which the system may not be

properly detected

The shape of the object may prevent the

sensor from detecting it. Pay particular

attention to the following objects:

●

Wires, fences, ropes, etc.

●

Cotton, snow and other materials that

absorb sound waves

●

Sharply-angled objects

●

Low objects

●

Tall objects with upper sections project-

ing outwards in the direction of your vehi-

cle

People may not be detected if they are

wearing certain types of clothing.

■

Situations in which the system may not

operate properly

Certain vehicle conditions and the sur-

rounding environment may affect the ability

of a sensor to correctly detect objects. Par-

ticular instances where this may occur are

listed below.

●

There is dirt, snow, water drops or ice on

a sensor. (Cleaning the sensors will

resolve this problem.)

●

A sensor is frozen. (Thawing the area will

resolve this problem.)

In especially cold weather, if a sensor is

frozen the sensor display may be dis-

played abnormally, or objects, such as a

wall, may not be detected.

●

When a sensor or the area around a sen-

sor is extremely hot or cold.

●

On an extremely bumpy road, on an

incline, on gravel, or on grass.

●

When vehicle horns, vehicle detectors,

motorcycle engines, air brakes of large

vehicles, the clearance sonar of other

vehicles or other devices which produce

ultrasonic waves are near the vehicle

●

A sensor is coated with a sheet of spray

or heavy rain.

●

If objects draw too close to the sensor.

●

When a pedestrian is wearing clothing

that does not reflect ultrasonic waves (ex.

skirts with gathers or frills).

●

When objects that are not perpendicular

to the ground, not perpendicular to the

vehicle traveling direction, uneven, or

waving are in the detection range.

●

Strong wind is blowing

●

When driving in inclement weather such

as fog, snow or a sandstorm

●

When an object that cannot be detected

is between the vehicle and a detected

object

●

If an object such as a vehicle, motorcycle,

bicycle or pedestrian cuts in front of the

vehicle or runs out from the side of the

vehicle

●

If the orientation of a sensor has been

changed due to a collision or other

impact

●

When equipment that may obstruct a

sensor is installed, such as a towing eye-

let, bumper protector (an additional trim

strip, etc.), bicycle carrier, or snow plow

●

●

When a tire chains or an emergency tire

puncture repair kit is used

■

Situations in which the system may

operate even if there is no possibility of a

collision

In some situations, such as the following, the

system may operate even though there is no

possibility of a collision.

●

When driving on a narrow road

●

When driving toward a banner, flag,

low-hanging branch or boom barrier

(such as those used at railroad crossings,

mated path of the vehicle.

Object
Calculated vehicle route

When the vehicle is moving, the side sensors or side cameras can detect objects.
While the vehicle is moving, if a detected object can no longer be detected by the
side sensors or side cameras, the location of the object relative to the vehicle is
estimated. If the object is determined to be in the estimated path of the vehicle, the
object warning function will operate.

Object detected by side sensors or side cameras

The vehicle is stopped and objects along the sides of the vehicle are not
detected.

■

Object warning function operating con-

ditions

The object warning function is operational

when the Lexus parking assist-sensor OFF

indicator is not illuminated or flashing and

any of the following conditions is met:

●

The Advanced Park is operating.

●

The vehicle moves about 7 m (23.0 ft.)

after the EV system is started.

●

The R shift position is selected.

●

After the shift position has been changed

from R to D, the vehicle has moved 7 m

(23.0 ft.) or less.

●

Camera switch has been pressed and the

center display is displayed.

●

The front or rear sensor detects a station-

ary object.

■

Detection of objects along the sides of

the vehicle

●

Objects along the sides of the vehicle are

not instantaneously detected. The loca-

tion of objects in relation to the vehicle is

estimated after they are first detected by

the front or rear side sensors, or side

cameras. Therefore, after the power

switch is changed to ON, even if an

object is along the side of the vehicle, it

may not be detected until the vehicle has

been driven a small amount and the side

sensors or side cameras completely scan

the areas along the sides of the vehicle.

●

If a vehicle, person, animal, etc. is

detected by a side sensor or side camera,

but then leaves the detection area of the

side sensor or side camera, the system

will assume the object has not moved.

WARNING

■

Object warning function

In situations such as the following, the

function may not operate correctly, pos-

sibly leading to an accident. Proceed

carefully.

●

When starting off shortly after the

power switch is turned to ON and a

small vehicle or other object which

cannot be detected by a front side sen-

sor is next to the vehicle.

In the situation shown in the following
illustration, even if the vehicle starts off, as
the vehicle on the left will not be
detected and the object warning function
will not operate.

●

When an object or person is in a posi-

tion which cannot be detected by the

side sensors or side cameras.

●

When, after the side sensors or side

cameras have completed scanning the

areas along the sides of the vehicle, a

vehicle, person, or other object

approaches the side of the vehicle and

cannot be detected.

●

When the outside rear view mirror is

closed, the side sensors or side cam-

eras cannot detect objects.
