Precautions for the radar sensor and rear bumper
The rear bumper of vehicles with a rear pre-crash safety system is a func-
tional part that has radio wave permeability. Observe the following to ensure
the system can function effectively:
Keep the rear bumper clean at all times.
Raindrops, ice or snow may deteriorate radar sensor performance.
Do not subject the radar sensor or surrounding area to a strong impact.
If the sensor moves even slightly out of position, the system may malfunc-
tion. If the sensor or surrounding area is subjected to a strong impact,
always have the area inspected and repaired by authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Do not disassemble the radar sensor.
Do not attach a towing hitch, bike holder, protective film or stickers to the
center portion of the rear bumper.
Do not replace the rear bumper with non-genuine parts or modify it.
For painting or repair of the rear bumper, consult with any authorized
Lexus dealer or repairer, or another duly qualified professional.
Precaution for the pre-crash intelligent head restraints
Do not put head restraint covers.
