The radar is behind the front grille below
the license plate.
A message displays if something obstructs
the radar signals from the sensor. The
system cannot detect a vehicle ahead and
does not function when something blocks
the sensor.
Note:
You cannot see the sensor, it is
behind a fascia panel.
Note: Keep the front of your vehicle free of
dirt, metal badges or objects. Vehicle front
protectors, aftermarket lights, additional
paint or plastic coatings could also degrade
sensor performance. Action
Cause
Clean the radiator grille in front of the radar
or remove any obstruction.
The surface of the radar in the radiator grille
is dirty or obstructed.
Wait a short period of time. It may take
several minutes for the radar to detect that
it is free from obstruction.
The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow interfere with the radar
signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Swirling water, snow or ice on the surface
of the road interfere with the radar signals.
Wait a short period of 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, a
blocked sensor message could display
when the sensor is not blocked. This can
happen, for example, when driving in
sparse rural or desert environments. A false
blocked condition self clears or clears after
you switch the ignition off and on. Switching to Normal Cruise
Control WARNING: Normal cruise control
will not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary.
