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.

The vehicle will also deceler-
ate/stop during the Traffic Jam
Assist (if equipped) controls, when
no driver’s response to the vehicle’s
warning to hold the steering wheel
is detected.

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.

■

Operating conditions

This system operates when all of the follow-

ing conditions are met:

●

When the LTA is on

Or during the Traffic Jam Assist controls (if
equipped)

●

When the vehicle speed is approximately

30 mph (50 km/h) or more

During the Traffic Jam Assist (if equipped)
controls, the system may operate at below
30 mph (50 km/h).

■

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,

hazard light switch, or turn signal lever is

operated)

●

When the driving assist switch is pressed

while in the stop and hold phase

●

When the power switch has been turned

from ON to off

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.
Vehicles with a driver monitor camera:
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 decel-
erate. 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 is stopped, the park-
ing brake will be applied automatically.
After entering the stop and hold phase,
the buzzer will continue sounding con-
tinuously and the emergency flashers
(hazard lights) will flash to warn other
drivers of the emergency.

WARNING

■

For safe use

●

Driving safely is solely the responsibil-

ity of the driver. Do not overly rely on

this system, and pay careful attention

to the surrounding conditions in order

to ensure safe driving.

●

The Traffic Jam Assist function is not an

automated driving system.

This function provides the driver with

information and driving assistance

according to the road shape and con-

ditions, traffic conditions, and the con-

dition of the driver themself. Always

pay careful attention to the surround-

ing conditions as use of the system is

the responsibility of the driver.

●

Depending on the condition of the sur-

rounding area, the road, or the driver,

the Traffic Jam Assist function may not

operate or operation may be sus-

pended. Also, it may not always be

able to achieve the same level of per-

formance. Read the operating condi-

tions of the function carefully. Do not

overly rely on this function and always

drive carefully.

●

As the recognition performance and

control performance of the Traffic Jam

Assist function are limited, driver oper-

ation is necessary to ensure safety

while the system is operating. Also, the

steering assist of this system is

designed to operate only for slow

steering operations during a traffic

jam. While this function is operating,

the lane deviation control function of

the LDA will not operate. If, for some

reason, the vehicle is about to deviate

the lane, it is the driver’s responsibility

to drive properly.

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.

In certain situations, this system may not

function to its fullest extent. Therefore it is

necessary for the occupants to visually

check for safety directly and using the

mirrors.

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’s surroundings and driving

safely.

■

To ensure the system can operate

properly

Make sure to observe the following pre-

cautions. The system may not operate

properly and may lead to an unexpected

accident. When these precautions can-

not be observed, turn the system off.

●

Do not damage the sensors, and

always keep them clean.

●

Do not attach a sticker or install an

electronic component, such as a back-

lit license plate (especially fluorescent

type), fog lights, fender pole or wire-

less 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 your Lexus dealer. If the

front or rear bumper needs to be

removed/installed or replaced, con-

tact your Lexus dealer.

●

Do not modify, disassemble or paint

the sensors.

●

Do not attach a license plate cover.

●

Keep your tires properly inflated.

●

Do not install a suspension other than a

genuine suspension.

■

Notes when washing the vehicle

●

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.

object.

●

Objects may not be detected if they are

too close to the sensor.

●

There will be a short delay between

object detection and display.

Even at low speeds, there is a possibility

that the object will come within the sen-

sor’s detection areas before the display is

shown and the warning beep 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.

●

If the meter malfunctions, the buzzer may

not sound.

■

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.

●

When strong winds are 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 such as a towing eyelet,

transport hook, bumper protector,

bumper trim, bicycle carrier or

snow-removal device (snow plow) is

installed near the sensor

■

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,

toll gates and parking lots)

●

When there is a rut or hole in the surface

of the road

●

When driving on a metal cover (grating),

such as those used for drainage ditches

●

When driving up or down a steep slope

●

If a sensor is hit by a large amount of

water, such as when driving on a flooded

road

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 sensors or side cam-

eras, but then leaves the detection area of

the side sensors or side cameras, the sys-

tem will assume the object has not

moved.
