Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obsta-
cle, the buzzer sounds continuously.
• Front corner sensors: Approximately 30 cm (1.0 ft.)
• Rear corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 35 cm (1.2 ft.)
When 2 or more obstacles are detected simultaneously, the buzzer
system responds to the nearest obstacle. If one or both come within
the above distances, the beep will repeat a long tone, followed by
fast beeps.
Approximately 50 cm (1.6 ft.)
Approximately 60 cm (2.0 ft.)
Approximately 150 cm (4.9 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles that
are extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object
etc.

The Lexus parking assist-sensor can be operated when
Front corner sensors:
• The power switch is in ON mode.
• The shift position is in other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
(At any speed when the shift position is in R)
Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift position is in R.
Lexus parking assist-sensor display
When an obstacle is detected while the rear view monitor system or Lexus park-
ing assist monitor is in use, the warning indicator will appear in the upper corner
of the screen even if the display setting has been set to off.
Sensor detection information
The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. 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 sensors 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 (lowered 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 a sensor to be closer than
they are.

The shape of the obstacle may prevent a sensor from detecting it. Pay particular
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 projecting 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 dis-
tance may shorten, or detection may be impossible.
• 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 sen-
sor’s detection areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and
possibly cause an accident.
Do not use the sensor at speeds in excess of 10 km/h (6 mph).
The sensors’ detection areas and reaction 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-sensor
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 dealer
or repairer, or another duly qualified and equipped professional.
The Lexus parking assist-sensor operation display flashes, and a buzzer
sounds when no obstacles are detected.
If the area around a sensor collides with something, or is subjected to strong
impact.
If the bumper collides with something.
If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.
If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
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 malfunctioning.
