4-5. Using the driving support systems

: If equipped

With the Secondary Collision Brake
(Rear Impacts while Stopped), the rear
side radar sensors detect a following
vehicle driving in the same lane while
the vehicle is stopped. If the system
determines that the possibility of a
rear-end collision is very high, the
brakes and brake lights will be auto-
matically controlled to reduce the vehi-
cle speed after the rear-end collision
and help reduce the possibility of fur-
ther damage due to a secondary colli-
sion.

Secondary Collision Brake
(Rear Impacts while
Stopped)

The Secondary Collision Brake
(Rear Impacts while Stopped) is a
system that uses the rear side radar
sensors located on the inside of the
rear bumper. When the system
determines that the possibility of a
rear-end collision while the vehicle
is stopped is very high, the brakes
are controlled automatically to help
reduce the possibility of further
damage due to a secondary colli-
sion.

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 Sec-

ondary Collision Brake (Rear Impacts

while Stopped) is an auxiliary system that

controls the brakes automatically when it

determines that the possibility of a

rear-end collision with the following vehi-

cle driving in the same lane is very high

while the vehicle is stopped. As the Sec-

ondary Collision Brake (Rear Impacts

while Stopped) may not function to its

fullest extent in certain situations, the

driver’s own visual confirmation of safety

is necessary. Over reliance on this func-

tion may lead to an accident resulting

death or serious injury.

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.

■

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.

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.

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 any

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

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 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 approximately 7 m

(23.0 ft.) after the hybrid system is

started.

●

The R shift position is selected.

●

After the D shift position has been

selected, 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.

RCTA (Rear crossing traffic
alert) function

The RCTA function uses the BSM
rear side radar sensors installed
behind the rear bumper. This func-
tion is intended to assist the driver
in checking areas that are not easily
visible when backing up.

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 RCTA

function is only a supplementary function

which alerts the driver that a vehicle is

approaching from the right or left at the

rear of the vehicle. As the RCTA function

may not function correctly under certain

conditions, the driver’s own visual confir-

mation of safety is necessary. Over reli-

ance on this function may lead to an

accident resulting death or serious injury.

The PKSB (Parking Support Brake)
system consists of the following
functions that operate when driving
at a low speed or backing up, such
as when parking. When the system
determines that a collision with a
detected object or pedestrian is
high, a warning operates to urge
the driver to take evasive action. If
the system determines that the pos-
sibility of a collision with a detected
object or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

■

Cautions regarding the use of the sys-

tem

Do not overly rely on the system, as

doing so may lead to an accident. Always

drive while checking the safety of the

surroundings of the vehicle.

Depending on the vehicle and road con-

ditions, weather, etc., the system may not

operate.

The detection capabilities of sensors,

radars and camera are limited. Always

drive while checking the safety of the

surroundings of the vehicle.

●

The driver is solely responsible for safe

driving. Always drive carefully, taking

care to observe your surroundings.

The PKSB (Parking Support Brake)

system is designed to provide support

to lessen the severity of collisions.

However, it may not operate in some

situations.

●

The PKSB (Parking Support Brake)

system is not designed to stop the

vehicle completely. Additionally, even

if the system has stopped the vehicle, it

is necessary to depress the brake

pedal immediately as brake control will

be canceled after approximately 2

seconds.

●

It is extremely dangerous to check the

system operations by intentionally

driving the vehicle into the direction of

a wall, etc. Never attempt such actions.

■

When to disable the PKSB (Parking

Support Brake) system

In the following situations, disable the

PKSB (Parking Support Brake) as the

system may operate even though there is

no possibility of a collision.

●

truck or other transport vessel

●

If the suspension has been modified or

tires of a size other than specified are

installed

●

If the front of the vehicle is raised or

lowered due to the carried load

●

When equipment that may obstruct a

sensor is installed, such as a towing

eyelet, bumper protector (an addi-

tional trim strip, etc.), bicycle carrier, or

snow plow

●

When using automatic car washing

devices

●
