Detection issues
The radar sensor has a limited field of vision. In some situations it may not detect vehicles at all or detect a vehicle later than expected.
Detection issues can occur:
• When driving on a different line than the vehicle in front.
• With vehicles that edge into your lane. These vehicles can only be detected once they have moved fully into your lane.
• There may be issues with the detection of vehicles in front when driving into and coming out of a bend or curve in the road.
In these cases ACC may brake late or unexpectedly. The driver should stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone may be altered causing missed or false vehicle detections. Check with your authorized dealer to have the ACC radar checked for proper coverage and operation.
