A message will display if the radar signals
from the sensor have been obstructed. The
sensor is located behind a fascia cover
near the driver side of the lower grille. A
vehicle ahead cannot be detected and the
system will not function when the radar
signals are obstructed. The following table
lists possible causes and actions for this
message being displayed.
Action Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that it is no
longer obstructed
The surface of the radar in the grille is clean
but the message remains in the display.
Do not use the system in these condition
because it may not detect, warn, or respond
to potential collisions.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these condition
because it may not detect, warn, or respond
to potential collisions.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is
possible to get a blockage warning and not
be blocked. This can happen, for example,
when driving in sparse rural or desert
environments. A false blocked condition
will either self clear or clear after a key
cycle. Switching to Normal Cruise
Control
WARNING
Normal cruise control will not brake
due to slower vehicles. Always be
aware of which mode is selected and
apply the brakes when necessary.
