2023 Ford Expedition Owner’s Manual — Adaptive Cruise Control Limitations

Sensor Limitations

WARNING:  On rare occasions, detection issues can occur due to the road infrastructures, for example bridges, tunnels and safety barriers. In these cases, the system may brake late or unexpectedly. At all times, you are responsible for controlling your vehicle, supervising the system and intervening, if required.    WARNING:  If the system malfunctions, have your vehicle checked as soon as possible.    WARNING:  Large contrasts in outside lighting can limit sensor performance.    WARNING:  The system only warns of vehicles detected by the radar sensor. In some cases there may be no warning or a delayed warning. Apply the brakes when necessary. Failure to follow this instruction could result in personal injury or death.    WARNING:  The system may not detect stationary or slow moving vehicles below 6 mph (10 km/h).    WARNING:  The system does not detect pedestrians or objects in the road.    WARNING:  The system does not detect oncoming vehicles in the same lane.    WARNING:  The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction.    WARNING:  The system may incorrectly track lane markings as other structures or objects. This can result in a false or missed warning.

1.Camera. 2.Radar sensor.

The camera is on the windshield behind the interior mirror.

The radar sensor is in the lower grille.

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.

A message displays if something obstructs the camera or the sensor. When something blocks the sensor, the system cannot detect a vehicle ahead and does not function.   See   Adaptive Cruise Control – Information Messages - Vehicles With: Lane Centering. 

The radar sensor has a limited field of view. It may not detect vehicles at all or detect a vehicle later than expected in some situations. The lead vehicle image does not illuminate if the system does not detect a vehicle in front of you.

Detection Issues Can Occur:

AWhen driving on a different line than the vehicle in front. BWith vehicles that edge into your lane. The system can only detect these vehicles once they move fully into your lane. CThere 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, the system may unexpectedly brake or brake late.

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 detection.

Optimal system performance requires a clear view of the road by the windshield camera.

Optimal performance may not occur if:

• The camera is blocked.
• There is poor visibility or lighting conditions.
• There are bad weather conditions.
