Cause
A message displays if something obstructs
the radar signals from the sensor. The sensor
is located behind a fascia cover near the
driver side of the lower grille. The system
cannot detect a vehicle ahead and will not
function when something obstructs the radar
signals. The following table lists possible
causes and actions for this message
displaying.
Clean the grille surface in front of the radar or remove the object
causing the obstruction.
Wait a short time. It may take several minutes for the radar to detect
that it is free from obstruction.
Do not use the system in these conditions because it may not detect
any vehicles ahead.
Do not use the system in these conditions because it may not detect
