Enable or disable Reverse Brake Assist on Ford F-150

Reverse Braking Assist feature on Ford F-150 reduces impact damage or avoids a collision completely by using the sensors on the rear of your vehicle and applying automatic braking.

Reverse Braking Assist functions when in reverse (R) and traveling at a speed of 1–7 mph (2–12 km/h). If the system detects an obstacle behind your F-150, it provides a warning through the rear parking aid or cross traffic alert system.

The system only applies the brakes for a short period of time when an event occurs. Act as soon as you notice the brakes apply in order to remain in control of the vehicle. If the system determines that a collision with an obstacle may occur, full braking may apply.

The brake assist feature can be enabled or disable via the SYNC 4 infotainment system on Ford F-150.

  1. Select Features on the touchscreen.
  2. Select Driver Assistance.
  3. Switch Reverse Brake Assist on or off.
Touch the toggle button next to ‘Reverse Brake Assist’ to enable or disable the feature.

Note: The system is unavailable when rear parking aid or cross traffic alert is off.

Overriding Reverse Braking Assist

There could be instances when unexpected or unwanted braking occurs. Firmly pressing the accelerator pedal or switching the feature off overrides the system.

System Limitations

  • Certain add-on devices around the bumper or fascia may create false alerts. For example, large trailer hitches, bicycle or surfboard racks, license plate brackets, bumper covers or any other device that may block the normal detection zone of the system. Remove the add-on device to prevent false alerts.
  • The system does not react to small or moving objects, particularly those close to the ground.
  • The system does not operate during hard acceleration or steering.
  • If your vehicle sustains damage to the bumper or fascia leaving it misaligned or bent, it could alter the sensing zone causing inaccurate measurement of obstacles or false alerts.
  • Vehicle loading and suspension changes can impact the angle of the sensors and may change the normal detection zone of the system resulting in inaccurate measurement of obstacles or false alerts.
  • When you connect a trailer, the system may detect the trailer and provide an alert, or the system turns off. If the system does not turn off, switch the system off manually after you connect the trailer.
  • You may experience reduced system performance on road surfaces that limit deceleration. For example, roads with ice, loose gravel, mud or sand.
  • The system may not operate properly during severe weather conditions, for example snow, ice, heavy rain and spray.
  • Some situations and objects prevent hazard detection. For example low or direct sunlight, inclement weather, unconventional vehicle types, and pedestrians.
