Buzzer operation and distance to an object
A buzzer sounds when the sensors are operating. ●
The buzzer sounds faster as th e vehicle approaches an object.
When the vehicle comes within the following distance of the object, the
buzzer sounds continuously: Approximately 1.2 ft. (35 cm). ●
When 2 or more objects are detected simultaneously, the buzzer system
responds to the nearest object. If on e or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.(blinking

The intuitive parking assist can be operated when ●
Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in other than P.
• The vehicle speed is less than about 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 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 ●
Vehicles with a Lexus Display Audio system/navigation system (8-inch display): When
an object is detected while the Lexus parking assist monito r or panoramic view monitor
is in use, the warning indicator will appear in the up per part of the scre en even if the dis-
play setting has been set to off.●
Vehicles with a navigation system (12.3-inch display): If the intuit ive parking assist dis-
play is set to on, detected objects will also be displayed on the panoramic view monitor.
For details, refer to “NAVIGATION SYSTEM OWNER’S MANUAL”. ■
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 object. Particular 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 th e 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.
• When a sensor or the area around a sensor is extremely hot or cold.
• 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 bumper or sensor re ceives a strong impact.
• If the vehicle is significantly tilted.
• 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 objects draw too close to the sensor.
• 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.

334 4-5. Using the driving support systems
RX350/RX350L_U ●
The shape of the object may prevent a sensor from detecting it. Pay particular attention
to the following objects:
• 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 object and other factors, the detection distance may
shorten, or detectio n may be impossible.
• Objects may not be detected if they are too close to the sensor.
• There will be a short dela y between object detection and display. Even at slow
speeds, there is a possibility that the obje ct 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 Parking Assist Sensor” is di splayed on the multi- information 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 object may not be detected. If the sensor thaws out, the system should
return to normal. ■
If “Parking Assist Malfunction” is di splayed 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. ■

RX350/RX350L_U WARNING ■
When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driv en 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 th e 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.●
The vehicle is equipped with a fender pole or wireless antenna. ●
The front or rear bumper or a se nsor receives a strong impact.●
A non-genuine Lexus suspension (lower ed suspension, etc.) is installed.●
Towing eyelets are installed. ●
A backlit license plate is installed. ■
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. ●
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 withou t 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 water or steam to the sensor area.
Doing so may result in th e sensor malfunctioning.●
When using a high pressure washer to wa sh the vehicle, do not spray the sensors
directly, as doing so may cause a sensor to malfunction. ●
When using steam to clean the vehicle, do not direct steam too close to the sensors
as doing so may cause a sensor to malfunction.

336 4-5. Using the driving support systems
RX350/RX350L_U The system will operate in situations such as the following if a stationary object is
detected in the traveling direction of the vehicle.
◆ When traveling at a low speed and the brake pedal is not depressed, or is
depressed late
 : If equippedIntelligent Clearance Sonar (ICS) If a collision with a wall or other stationary object may occur due to the vehicle
suddenly moving forward due to an ac cidental accelerator pedal operation,
the vehicle moving the unintended dire ction due to the wrong shift position
being selected, or while parking or trav eling at low speeds, the sensors detect
stationary objects, such as a wall, in th e traveling direction of the vehicle, and
the system operates to lessen an impact with a stationary object and reduce
the resulting collision damage.

RX350/RX350L_U If a rear radar sensor detects a vehicle ap proaching from the right or left at the
rear of the vehicle and the system determ ines that the possibility of a collision is
high, this function will perform brake control to reduce the likelihood of an
impact with the approaching vehicle. ■
Examples of system operation
This function will operate in situations such as the following if a vehicle is
detected in the traveling direction of the vehicle.
