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

system

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 rap-

idly 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 nec-

essary.

■

The system can be operated when

●

The engine switch is in ON.

●

Intuitive parking assist function is on.

●

The vehicle speed is less than about 6

mph (10 km/h).

●

The shift lever is in other than P.

■

If “Parking Assist Unavailable” is dis-

played on the multi-information 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.

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

malfunction. Have the vehicle inspected

by your Lexus dealer.

●

Water may be continuously flowing over

the sensor surface, such as in a heavy

rain. When the system determines that it

is normal, the system will return to nor-

mal.

■

Sensor detection information

●

The sensor’s detection areas are limited

to the areas around the vehicle’s 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 11.9 in. (30 cm) before the

WARNING

■

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.

●

When using steam to clean the vehi-

cle, do not direct steam too close to

the sensors as doing so may cause a

sensor to malfunction.

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.

●

If the front of the vehicle is raised or low-

ered due to the carried load.

●

If the vehicle cannot be driven in a stable

manner, such as when the vehicle has

been in an accident or is malfunctioning.

PKSB (Parking Support
Brake)

The 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 deter-
mines that the possibility of a colli-
sion with a detected object or
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action. If the system
determines that the possibility 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 collision.

WARNING

■

Cautions regarding the use of the

system

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 and

radars 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 Parking Support Brake system is

designed to provide support to lessen

the severity of collisions. However, it

may not operate in some situations.

●

The Parking Support Brake system is

not designed to stop the vehicle com-

pletely. Additionally, even if the system

has stopped the vehicle, it is necessary

to depress the brake pedal immedi-

ately 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 Parking Support

Brake

In the following situations, disable the

Parking Support Brake as the system

may operate even though there is no

possibility of a collision.

●

When inspecting the vehicle using a

chassis roller, chassis dynamo or free

roller

●

When loading the vehicle onto a boat,

truck or other transport vessel

If the Parking Support Brake has oper-

ated

If the vehicle is stopped due to operation of

the Parking Support Brake, the Parking

Support Brake will be disabled and the

PKSB OFF indicator will illuminate. If the

Parking Support Brake operates unneces-

sarily, brake control can be canceled by

depressing the brake pedal or waiting for

approximately 2 seconds for it to automati-

cally be canceled. Then, the vehicle can be

operated by depressing the accelerator

pedal.

■

Re-enabling the Parking Support Brake

To re-enable the Parking Support Brake

when it is disabled due to operation of the

Parking Support Brake, either enable the

system again (



P.277), or turn the engine

switch off and then back to ON.

Additionally, if any of the following condi-

tions are met, the system will be re-enabled

automatically and the PKSB OFF indicator

will turn off:

●

The P shift position is selected

●

The object is no longer detected in the

traveling direction of the vehicle

●

The traveling direction of the vehicle
changes

: Except when the Parking Support Brake

function (Pedestrians Rear of the Vehi-
cle) operated.

■

If “Parking Support Brake Unavailable”

is displayed on the multi-information

display and the PKSB OFF indicator

comes on

If the vehicle is stopped due to operation of

the Parking Support Brake, the Parking

Support Brake will be disabled and the

PKSB OFF indicator will illuminate.

●

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.

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 this message is displayed only when the

R shift position is selected, the rear cam-

era lens may be dirty. Clean the camera

lens. If this message is displayed when the

shift position is any position other than R,

a sensor on the front or rear bumper may

be dirty. Clean the sensors and their sur-

rounding area on the bumpers.

●

If this message continues to be displayed

even after cleaning the sensor, or is dis-

played even though the sensor is clean,

have the vehicle inspected by your Lexus

dealer.

■

If a battery terminal has been discon-

nected and reconnected

The system needs to be initialized. To initial-

ize the system, drive the vehicle straight

ahead for 5 seconds or more at a speed of

approximately 22 mph (35 km/h) or more.
