Sensor detection information

The sensor’s detection areas are limited

to the areas around the vehicle’s front

and rear bumpers.

Certain vehicle conditions and the sur-

rounding environment may affect the

ability of the sensor to correctly detect

obstacles. Particular instances where this

may occur are listed below.

• There is dirt, snow or ice on the sensor.

(Wiping the sensors will resolve this

problem.)

• The sensor is frozen. (Thawing the area

will resolve this problem.)

In especially cold weather, if a sensor is

frozen the screen may show an abnormal

display, or obstacles may not be

detected.

• The sensor is covered in any way.

• The vehicle is leaning considerably to

one side.

• On an extremely bumpy road, on an

incline, on gravel, or on grass.

• The vicinity of the vehicle is noisy due to

vehicle horns, motorcycle engines, air

brakes of large vehicles, or other loud

noises producing ultrasonic waves.

• There is another vehicle equipped with

parking assist sensor in the vicinity.

• The sensor is splashed with water or

heavy rain.

• The vehicle is equipped with a fender

pole or wireless antenna.

• Towing eyelets are installed.

• The bumper or sensor receives a strong

impact.

• The vehicle is approaching a tall or

curved curb.

• In harsh sunlight or intense cold weather.

• The area directly under the bumpers is

not detected.

• If obstacles draw too close to the sensor.

• A non-genuine Lexus suspension (low-

ered suspension etc.) is installed.

• People may not be detected if they are

wearing certain types of clothing.

In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.

The shape of the obstacle may prevent

the sensor from detecting it. Pay particu-

lar attention to the following obstacles:

• Wires, fences, ropes, etc.

• Cotton, snow and other materials that

absorb sound waves

• Sharply-angled objects

• Low obstacles

• Tall obstacles with upper sections pro-

jecting outwards in the direction of your

vehicle

The following situations may occur

during use.

• Depending on the shape of the obstacle

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• Obstacles may not be detected if they

are too close to the sensor.

• There will be a short delay between

obstacle detection and display. Even at

slow speeds, there is a possibility that the

obstacle will come within the sensor’s

detection areas before the display is

shown and the warning beep sounds.

• Thin posts or objects lower than the sen-

sor may not be detected when

approached, even if they have been

266

4-5. Using the driving support systems

detected once.

• It might be difficult to hear beeps due to

the volume of the audio system or air flow

noise of the air conditioning system.

• It might be difficult to hear beeps due to

the sounds of other systems.

Customization

Some functions can be customized.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

Do not use the sensor at speeds in

excess of 10 km/h (6 mph).

The sensors’ detection areas and reac-

tion times are limited. When moving

forward or reversing, check the areas

surrounding the vehicle (especially the

sides of the vehicle) for safety, and

drive slowly, using the brake to control

the vehicle’s speed.

Do not install accessories within the

sensors’ detection areas.

NOTICE

When using Lexus parking assist-sen-

sor

In the following situations, the system

may not function correctly due to a sen-

sor malfunction etc. Have the vehicle

checked by any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer.

The Lexus parking assist-sensor oper-

ation display flashes or shows continu-

ously, and a beep sounds when no

obstacles are detected.

If the area around a sensor collides

with something, or is subjected to

strong impact.

If the bumper or grille collides with

something.

If the display flashes or shows continu-

ously without beeping, except when

the mute function has been turned on.

If a display error occurs, first check the

sensor.

If the error occurs even when there is

no ice, snow or mud on the sensor, it is

likely that the sensor is malfunctioning.

Notes when washing the vehicle

strong impact to the sensor or its sur-

rounding area

• When the distance between your vehicle

and a guardrail, wall, etc. that enters the

detection area is short

• When driving up and down consecutive

steep inclines, such as hills, dips in the

road, etc.

• When vehicle lanes are narrow, or when

driving on the edge of a lane, and a vehi-

cle traveling in a lane other than the adja-

cent lanes enters the detection area

• When driving on roads with sharp bends,

consecutive curves, or uneven surfaces

• When the tires are slipping or spinning

• When the distance between your vehicle

and a following vehicle is short

• When an accessory (such as a bicycle

carrier) or towing eyelet is installed to the

rear of the vehicle

Operation of the RCTA function

The RCTA function uses radar sensors to detect vehicles approaching from the
right or left at the rear of the vehicle and alerts the driver of the presence of such
vehicles by flashing the outside rear view mirror indicators and sounding a buzzer.

WARNING

Cautions regarding the use of the

function

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The BSM function is a supplementary

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 BSM function. 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.
