Traffic Jam Assist is a system which,
through confirmation of the conditions
by the driver, provides lane keeping,
accelerating/decelerating, stopping,
and starting off support on some high-
ways and expressways. Also, in an
emergency, the system can decelerate
and stop, to help avoid a collision or
help reduce the impact of a collision.

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.

WARNING

●

Even if Traffic Jam Assist is operating

properly, the surrounding conditions

as recognized by the driver and

detected by the system may differ.

Therefore, it is necessary for the driver

to pay attention, assess risks, and

ensure safety. Over-reliance on this

system to drive the vehicle safely may

lead to an accident resulting in death

or serious injury.

●

While the Traffic Jam Assist function is

operating, as driver operation may

become necessary, the driver must

ensure they have clear visibility of their

surroundings.

●

In certain situations, a message urging

the driver to hold the steering wheel

may be displayed by the Traffic Jam

Assist function. In this case, hold the

steering wheel and drive the vehicle

manually to ensure safety.

●

detect the following objects. Operate

the steering wheel, accelerator pedal,

or brake pedal as necessary to avoid a

collision. As the function will not be

able to provide appropriate control,

using it may lead to an accident result-

ing in death or serious injury.

• Objects on the road surface

• Vehicles outside of a lane (such as on

the shoulder of the road)

• Potholes, cracks, ruts, or other road

damage

• Road construction zones

• Vehicles running in parallel with your

vehicle or nearby walls

• Animals

■

Situations in which Traffic Jam Assist

Function should not be used

Do not use Traffic Jam Assist Function in

situations such as the following. As the

BSM (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 supple-

mentary 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 cor-

rectly under certain conditions, the

driver’s own visual confirmation of

safety is necessary.

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 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.

■

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.

330

4-5. Using the driving support systems

■

The system can be operated when

●

The power switch is ON.

●

Intuitive parking assist function is on.

●

The vehicle speed is less than about 6

mph (10 km/h).

●

A shift position other than P is selected.

■

If “Parking Assist Unavailable Sensor

Blocked” is displayed on the multi-infor-

mation display

A sensor may be covered with water drops,

ice, snow, dirt, etc.

Remove the water drops, ice, snow, dirt,

etc., from the sensor to return the system to

normal.
If a sensor is dirty, the position of the dirty

sensor will be shown on the display.
Also, due to ice forming on a sensor at low

temperatures, a warning message may be

displayed or the sensor may not be able to

detect an object. Once the ice melts, the

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

your Lexus dealer.

■

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

during 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 1.0 ft. (30 cm) 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.

WARNING

●

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
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 warning function operating con-

ditions

The object warning function is operational

when the intuitive parking assist OFF indi-

cator is not illuminated or flashing and any

of the following conditions is met:

●

The Advanced Park is operating.

●

The vehicle moves approximately 23.0 ft.

(7 m) after the hybrid system is started.

●

The R shift position is selected.

●

After the D shift position has been

selected, the vehicle has moved 23.0 ft.

(7 m) 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.
