■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle, the
buzzer sounds continuously:
• Front center sensors: Appr oximately 30 cm (1.0 ft.)
• Corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 35 cm (1.1 ft.)
●When 2 or more obstacles are detect ed simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
Approximately 60 cm (2.0 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 lever is in other than P.
• The vehicle speed is less th an about 10 km/h (6 mph).
(At any speed when the shift lever is in R)
●Front center sensors:
• The power switch is in ON mode. • The shift lever is in other than P or R.
• The vehicle speed is less th an about 10 km/h (6 mph).
●Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
■Lexus parking assist-sensor display
Vehicles with a Lexus Display Audio system: When an obstacle is detected while the
Lexus parking assist monitor is in use, the warning indicator will appear in the upper part of the screen even if the disp lay setting has been set to off.
■If a message is displayed on the multi-information display

■Customization
Some functions can be customized. ( P. 314,657)
WARNING
■When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle be ing 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 vehi- cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.

WARNING
■Sensor detection information
●The sensor’ detection areas are limited to the areas around the vehicle’ bumper.
●Certain vehicle conditions and surrounding environments, such as the following, may
affect the ability of the sensor s to correctly detect objects. Pay particular attention in the following situations. Failure to do so may result in the vehicle being driven
unsafely, possibly leading to an accident.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob- lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal dis- play, 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 lo ud 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 (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 ar e 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 materi als that absorb sound waves
• Sharply-angled objects • Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle • People, animals and other moving objects
• People wearing certain types of clothing

WARNING
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor. • There will be a short delay between obstac le detection and display. Even at slow
speeds, there is a possibility that the ob stacle will come within the sensor’ detec-
tion areas before the display is shown and the buzzer sounds. • Thin posts or objects lower than th e 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.
NOTICE
■When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sensor mal-
function, etc. Have the vehicle checked by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
●The Lexus parking assist-sensor operation display flashes, and a buzzer sounds when
no obstacles are detected.
●If the area around a sensor co llides 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, sn ow or mud on the sensor, it is likely that the
sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of wa ter or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
