Which F-150 vehicles have speed sign recognition?

System Limitations

Speed sign recognition may not operate correctly due to:

  • Outdated map data.
  • Incorrect recognition of speed limits by the sensor of signs on parallel roads or exit ramps.
  • Missed recognition of faded, dirty, or distorted signs.

Precautions

  • In cold and severe weather conditions the system may not function. Rain, snow and spray can all limit sensor performance.
  • The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction.
  • Do not carry out windshield repairs in the immediate area surrounding the sensor.
  • If your vehicle has a suspension kit not approved by us, the system may not correctly function.
  • The system may not detect all speed signs and may incorrectly read signs.
  • Always fit original parts from Ford when replacing headlamp bulbs. Other bulbs may reduce system performance.

Troubleshooting

Alert: Traffic Sign Reduced Performance See Manual

This message appears if the traffic sign data provided by the navigation system is unavailable due to weak or no signal. Wait for a short period of time for the signal to improve. If the message continues to appear, have the system checked as soon as possible.

Why does the speed limit change without any sign on the road?

The speed limit changes due to the speed limit data stored in the map data.

Why does speed sign recognition show a wrong speed limit?

The system shows a wrong speed limit due to incorrect and outdated map data or due to incorrect recognition of the speed limits by the camera.
