always keep them clean.
ODo not attach a sticker or install an
electronic component, such as a
backlit license plate (especially fluo-
rescent type), fog lights, fender pole or
wireless antenna near a radar sensor.
ODo not subject the surrounding area of
the sensor to a strong impact. If sub-
jected to an impact, have the vehicle
inspected by your Lexus dealer. If the
front or rear bumper needs to be
removed/installed or replaced, con-
tact your Lexus dealer.
