Note: 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. 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. This message
deactivates automatically when operational
conditions are correct. For example, when
the ambient temperature around the sensor
decreases or the sensor automatically
recalibrates successfully.
