Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating. ●
The buzzer beeps faster as the vehicl e approaches an obstacle. When the
vehicle comes within the following di stance of the obstacle, the buzzer
sounds continuously:
• Front center sensors (RC350/RC3 00): Approximately 1.0 ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Appr oximately 1.1 ft. (35 cm)●
When 2 or more obstacles are detected 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.
The diagram shows the detection range of th e sensors. Note that the sensors cannot
detect obstacles that are extremely close to the vehicle.
The range of the sensors may change depe nding on the shape of the object etc.Detection range of the sensors 

The intuitive parking assist can be operated when ●
Front center sensors (
RC350/RC300 ):
• 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). ●
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 about 6 mph (10 km/h).
(At any speed when the shift lever is in R) ●
Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R. ■
Muting the buzzer sound ●
To mute the buzzer sound:
The buzzer can be temporarily muted by pressing “OK” of the meter control switches
while an obstacle detectio n display is shown on the multi-information display.●
To cancel the mute:
Mute will be automatically canceled in the following situations.
• When the shift position is changed (except shifting from D to N, or N to D).
• When the vehicle speed has reached or exceeded 6 mph (10 km/h) with the shift
position in D.
• When the intuitive parking assist is turned off once and turned on again.
• When the engine switch is turned off once and turned to IGNITION ON mode
again.■

288 4-5. Using the driving support systems
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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.■
Limitations of the sensors ●
RC350/RC300: The detection areas of the sensors are limited to the areas around
the vehicle’s front and rear bumpers. ●
RC F: The detection areas of the sensors are limited to the areas around the vehicle’s
front corners and the rear bumpers. ●
Certain vehicle conditions and surrounding environments, such as the following, may
affect the ability of th e sensors to correctly detect obje cts. Pay particul ar attention in
the following situations. Failure to do so may result in the vehicle being driven
unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a se nsor (Cleaning the sensor will resolve this
problem.)
• When 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 objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bump y road, incline, gravel, or grass
• When 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
• When there is another vehicle equipped with parking assist sensor in the vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless antenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlig ht or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Lexus suspension (lowered suspension, etc.) is installed
In addition to the situations above, there are instances in which, because of their
shape, signs and other objects may be judged by the sensor to be closer than they
are.

Driving
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ●
The shape of an object may prevent the sens or from detecting it. Pay particular atten-
tion to the following:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
• Low objects
• Tall objects with upper sections projecting outwards in the direction of your vehi-
cle
• People, animals and other moving objects
• People wearing certain types of clothing ●
The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance
may be shortened, or detection may not be possible.
• Objects may not be detected if they are too close to a sensor.
• There will be a short delay between the de tection of an object and display of the
detection. Even at slow speeds, there is a possibility that the object will come
within a sensor’s detection area before the display is shown and a warning beep
sounds.
• Thin posts or objects lower than a 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 the audio system or air flow
noise of the air co nditioning system.
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 display flashes, and a beep 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 or grille collides with something. ●
If the display flashes or is displayed contin uously and a buzzer does not sound, except
when the mute function has been turned on.●
If a display error occurs , first check the sensor.
If the error occurs even when 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 th e sensor malfunctioning.
