■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

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.
■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 the sensors to correctly detect obje cts. Pay particular 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.

■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
●Vehicles that the sensors cannot detect due to
obstructions
• When backing up on a slope with a sharp change in grade

3004-5. Using the driving support systems

• Immediately after the BSM
main switch is turned on
• Immediately after the engine is st arted with the BSM main switch 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
