If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detections.
See an authorized dealer to have the radar
checked for proper coverage and
operation.
Blocked Sensor
E145632
The surface of the radar in the grille is dirty
or obstructed in some way.
The surface of the radar in the grille is clean
but the message remains in the display.
Heavy rain or snow is interfering with the
radar signals.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.
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.

Cruise Control
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 obstruc-
tion.
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 any vehicles
ahead.
Wait a short time or switch to normal cruise
control.
