Cruise Control 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. System Not Available Conditions that can cause the system to deactivate or prevent the system from activating when requested include: • a blocked sensor • high brake temperature • a failure in the system or a related system. Blocked Sensor E71621 Detection issues can occur: A B When driving on a different line than the vehicle in front. With vehicles that edge into your lane. The system can only detect these vehicles once they move 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. WARNINGS Do not use the system when towing a trailer with brake controls. Aftermarket trailer brakes will not function properly when the system is activated because the brakes are electronically controlled. Failing to do so may result in loss of vehicle control, which could result in serious injury. Do not use tire sizes other than those recommended because this can affect the normal operation of the system. Failing to do so may result in a loss of vehicle control, which could result in serious injury. C In these cases the system may brake late or unexpectedly. The driver should stay alert and intervene when necessary. 202 MKZ (CC9)
