CAUTION
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively. 
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and front grille cover clean at all times. 
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact. 
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by a Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.

Intuitive parking assist
: If equipped
The distance from your vehicle to nearby obstacles when parallel parking
or maneuvering into a garage is measured by the sensors and communi-
cated via the multi-information display and a buzzer. Always check the sur-
rounding area when using this system.

Buzzer operation and distance to an obstacle
A beep sounds when the corner senso rs and center sensors are operat-
ing.
● The buzzer beeps faster as the ve hicle approaches an obstacle. 
When the vehicle comes within the following distance of the obstacle,
the buzzer sounds continuously.
• Front corner sensors: Approximately 1.1 ft. (35 cm)
• Front center sensors: Approximately 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.

Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
Approximately 1.8 ft. (55 cm)
The diagram shows the 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.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A 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.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
In addition to the examples above, there are 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
attention 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 vehicle
