When driving
■ 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 trunk 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
■ 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 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.
