2021 Ford F-150 Owners Manual - Reverse Braking Assist

Reverse Braking Assist

Reverse Braking Assist reduces impact damage or avoids a collision completely by using the sensors on the rear of your vehicle.

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 vehicle, 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.

Note: 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.

Note: The system does not react to small or moving objects, particularly those close to the ground.

Note: The system does not operate during hard acceleration or steering.

Note: 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.

Note: 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.

Note: 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.

Note: You may experience reduced system performance on road surfaces that limit deceleration. For example, roads with ice, loose gravel, mud or sand.

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

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

If the system determines that a collision with an obstacle may occur, full braking may apply. Bring your vehicle to a stop a safe distance away from the obstacle.

A message and warning indicator appear when the system applies the brakes.

Why is reverse braking assist unavailable?

Make sure that all doors, liftgate and hood are closed. Drive the vehicle on a straight road for a short period. If the message remains, contact an authorized dealer.

Make sure the cross traffic alert system is on. See How Does Cross Traffic Alert Work (page 344).

Make sure the rear parking aid system is on. See What is the Rear Parking Aid (page 297).

Make sure traction control is on. See

Traction Control (page 284).

The vehicle has sustained a rear end impact. Contact an authorized dealer to have the sensors checked for proper coverage and operation.

An ABS, traction control or stability control event may have occurred. Reverse braking assist resumes operation when the event is complete.

Make sure the rear view camera and 360 degree camera are not dirty or obstructed. If dirty, clean the camera. If the message still appears after cleaning the camera, wait a short time and the message should clear. If the message does not clear, contact an authorized dealer.

Make sure there are no blocked or faulted sensors. See How Does Cross Traffic Alert Work (page 344).

You recently had your vehicle serviced, or the battery disconnected. Drive your vehicle a short distance to resume system operation.

Reverse braking assist does not function when you connect a trailer. Operation resumes when you disconnect the trailer.

Note: If the answers to why the system is unavailable do not assist in returning reverse braking assist to available, have the system checked as soon as possible.
