CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (→P. 257) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
●Excessive exhaust gas (black smoke) is coming from the vehicle ahead or other
vehicles around you, obscuring your front view
●The rear section of the vehicle ahead is extremely dirty
●The vehicle ahead has higher ground clearance

CAUTION
■To ensure the sensor functions correctly
Do not do the following to the sensor or grille as doing so may cause the sensor not
to function correctly and could result in an accident:
●Sticking or attaching anything to them
●Leaving them dirty
●Disassembling or subjecting them to strong shocks
●Modifying or painting them
●Replacing them with non-genuine parts
■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 grille cover clean at all times.
Clean the sensor and 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 your 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 di stance to an obstacle
A beep sounds when the corner sensors and center sensors are operat-
ing.
● The buzzer beeps faster as the vehicle 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.
