■

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 coated with a sheet of spray

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

detected once.

• It might be difficult to hear beeps due to

228

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.

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.

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 necessary.
