■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 obstacle, the
buzzer sounds continuously. • Front corner sensors: Ap proximately 1.0 ft. (30 cm)
• Front center sensors: Ap proximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.3 ft. (40 cm)
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If one or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
●You can change the volume of the warning beeps. ( P. 274)
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.6 ft. (50 cm)
Approximately 1.8 ft. (55 cm)
The diagram shows th e detection range
of the sensors. Note that the sensors
may not be able to 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 intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
(At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system or Multi-terrain Moni-
tor 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 detectio n 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. Pa rticular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• 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.
• The bumper or sensor re ceives 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 atten-
tion 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 projecting outwards in the direction of your vehi-
cle
●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 obstacle detection and display. Even at slow speeds, there is a possibility th at the obstacle will come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sens or may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.
■If “Clean Park Sonar”/“Clean Parking Assist Sensor” is displayed on the multi-informa-
tion display
A sensor may be dirty or covered with snow or ic e. In such cases, if it is removed from the
sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may no t be detected. If the sensor thaws out, the system should
return to normal.
■If “Check Park Sonar System”/ “Parking Assist Malfunction” is displayed on the multi-
information display
Depending on the malfunction of the sensor, the device may not be working normally.
Have the vehicle inspected by your Lexus dealer.
■Certification for the intuitive parking assist (Canada only)
This ISM device complies with Canadian ICES-001.
■Customization
Settings (e.g. buzzer sounds volume) can be changed.
(Customizable features: P. 584)

WARNING
■When using the intuitive parking assist
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 6 mph (10 km/h).
●The sensors’ detection areas and reaction ti mes 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.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by your Lexus dealer.
●A buzzer does not sound when you tu rn the intuitive parking assist on.
●The intuitive parking assist operation disp lay 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 a beep.
●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 water or steam to the sensor area.
Doing so may result in th e sensor malfunctioning.

Rear view monitor system
The rear view image is displayed when
the shift lever is in R and the engine
switch is in IGNITION ON mode.
The rear view monitor system will be
deactivated when the sh
ift lever is in any
position other than R.
When the shift lever is shifted to R and
any mode button (such as “SETUP”) is
pressed, the rear view monitor system is
canceled, and the screen is switched to
the mode of the button that was pressed.
: If equipped
The rear view monitor system assists th e driver by displaying guide lines and
an image of the view behind the vehi cle while backing up, for example while
parking.
The screen illustrations used in this text are intended as examples, and may dif-
fer from the image that is actually displayed on the screen.
