a strong impact, always have the area inspected and adjusted by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Do not disassemble the sensor.

to observe your surroundings and checking for any obstacles or other road
hazards.
Failure to do so may cause an accident resulting in death or serious injury.
