maneuvering into a garage is measured by the sensors and communicated via
the displays and a buzzer. Always check the surrounding area when using this
system.

You can change the buzzer sounds volu me and the screen operating conditions
when the power switch is in ON mode.
Press the “MENU” button on the Remote Touch, and then select on the
screen.
Select “Vehicle”, and then select “LEXUS Park Assist” on the screen.
Select the desired item.
The buzzer sounds volume can
be adjusted.
On or off can be selected for intu-
itive parking assist display.
Both the front or rear center sen-
sors display and tone indication
can be set.
■The intuitive parking assist 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 than about 6 mph (10 km/h).(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 than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
■Intuitive parking assist display
●Vehicles with 8-inch display: When an ob stacle is detected while the Lexus parking
assist monitor or panoramic view monitor is in use, the warning indicator will appear in
the upper part of the screen even if the display setting has been set to off.
●Vehicles with 12.3-inch display: If the intu itive parking assist display 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 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. 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.
• Towing eyelets are installed.
• 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 Parking Assist Sensor” is displayed 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 obstacle may not be detected. If the sensor thaws out, the system should
return to normal.
■If “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 vehicles sold in Canada
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme a la norme NMB-001 du Canada.
■Customization
Some functions can be customized. ( P. 344, 607)
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 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.
●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 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 the sensor malfunctioning.

■Conditions under which the RCTA fu nction will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles and/or
objects:
●Vehicles approaching from directly behind
●Vehicles backing up in a parkin g space next to your vehicle
●Guardrails, walls, signs, parked vehi cles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking spaces next to your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or object may occur.
■Conditions under which the RCTA function may not function correctly
●The RCTA function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a stro ng impact to the sensor or its surround-
ing area
• When mud, snow, ice, a sticke r, etc. is covering the sensor or surrounding area on
the rear bumper
• When driving on a road surf ace that is wet with standing water during bad weather,
such as heavy rain, snow, or fog
• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When a vehicle is approaching at high speed
• When towing a trailer (vehicles with towing package)
●Vehicles that the sensors cannot detect due to
obstructions
• When backing up on a slope with a sharp change in grade

RX450h_U_OM0E013U• Immediately after the RCTA function is turned on
• Immediately after the hybrid system is started with the RCTA function on
●Instances of the RCTA function unnecessari
ly detecting a vehicle and/or object may
increase in the following situations:
• When a vehicle passes by th e side of your vehicle
• When the distance between your vehicle and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may re flect electrical waves toward the rear of
the vehicle, is short
• When backing out of a shallow angle park-
ing spot
• When the sensors cannot detect a vehicle due to obstructions
• When the parking space faces a street and vehicles are being driven on the street
