2021 Ford F-150 Owners Manual - Speed Sign Recognition



Speed Sign Recognition

Speed sign recognition detects speed limit signs to inform you of the current speed limit. Detected speed signs appear in the information display.

Speed sign recognition uses a sensor behind the interior mirror to detect speed signs.

If your vehicle has speed sign recognition with navigation, stored speed sign data may influence the indicated speed limit value.

WARNING: You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.

WARNING: In cold and severe weather conditions the system may not function. Rain, snow and spray can all limit sensor performance.

WARNING: The system may not operate properly if the sensor is blocked. Keep the windshield free from obstruction.

Note: Do not carry out windshield repairs in the immediate area surrounding the sensor.

Note: If your vehicle has a suspension kit not approved by us, the system may not correctly function.

Note: The system may not detect all speed signs and may incorrectly read signs.

Note: Always fit our original parts when replacing headlamp bulbs. Other bulbs may reduce system performance.

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    Outdated map data.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.
