Clean the grille surface in front of the radar

tion.

or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there
is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display

Contact an authorized dealer to have the
radar checked for proper coverage and
operation.
Radar is out of alignment due to a front end
impact.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully.
