D Radar Cruise Control Warning
G13073
If the system cannot
vehicle−to−vehicle distance because of a dirty millimeter
wave radar sensor or grille cover while the dynamic radar
cruise control is on, the master warning light comes on
and the "CRUISE" indicator light flashes. At this time a
warning tone sounds and the above message appears.
If this message appears, clean the sensor and grille cover with
a soft cloth and try setting the preset speed again. If the dirt
is removed without cleaning, the system will automatically
enter the "RADAR READY" mode. If the system does not enter
the "RADAR READY" mode even after cleaning or the
message remains on the display, the system might be
malfunctioning. Although it is no problem to continue driving,
contact your Lexus dealer.
