■ When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations:
● 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.)
● Vehicles that cut in suddenly
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
● Keep the sensor and front grille clean at all times.
Clean the sensor and front grille 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 become inaccurate
or 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 or surrounding area.
● Do not modify or paint the sensor and grille cover.
