2021 Ford F-150 Owners Manual - Cross Traffic Alert



Cross Traffic Alert

The system alerts you of vehicles approaching from the sides behind your vehicle when you shift into reverse (R).

Cross Traffic Alert detects vehicles that approach at a speed between 4–37 mph (6–60 km/h). Coverage decreases when the sensors are partially, mostly or fully obstructed.

E142440

The sensor on the left-hand side is only partially obstructed and zone coverage on the right-hand side is maximized.

Zone coverage also decreases when parking at narrow angles. The sensor on the left-hand side is mostly obstructed and zone coverage on that side is severely reduced.

Note: Slowly reversing helps increase the coverage area and effectiveness.

WARNING: Do not use the cross traffic alert system as a replacement for using the interior and exterior mirrors or looking over your shoulder before reversing out of a parking space. The cross traffic alert system is not a replacement for careful driving.

WARNING: The system may not operate properly during severe weather conditions, for example snow, ice, heavy rain and spray. Always drive with due care and attention. Failure to take care may result in a crash.

CROSS TRAFFIC ALERT LIMITATIONS

Cross Traffic Alert may not correctly operate when any of the following occur:

    Something is blocking the sensors.
    Adjacently parked vehicles or objects are obstructing the sensors.
    Vehicles approach at speeds less than 4 mph (6 km/h) or greater than 37 mph (60 km/h).
    Your vehicle speed is greater than 7 mph (12 km/h).

3. Switch Cross Traffic Alert on or off.

Note: The system switches on every time you switch the ignition on. To permanently switch the system off, contact an authorized dealer.

The sensors are inside the brake lamp on both sides of your vehicle.

Note: Keep the sensors free from snow, ice and large accumulations of dirt.

Note: Do not cover the sensors with bumper stickers, repair compound or other objects.

Note: Blocked sensors may affect system accuracy.

If something is blocking the sensors, a message may appear in the information display when you shift into reverse (R).

Equipped)

Cross traffic alert with trailer coverage allows the system to continue operating with a trailer or trailer hitch attachment.

Cross traffic alert remains on when you attach a trailer in vehicles that come with blind spot information system with trailer tow under the following conditions:

    You connect a trailer.
    The trailer is a bike rack or cargo rack with a maximum length of 3 ft (1 m).
    You set the trailer length to 3 ft (1 m) in the information display.

Note: The system may not correctly operate when towing a trailer. For vehicles with an approved trailer tow module and tow bar, the system turns off when you attach a trailer. For vehicles with an aftermarket trailer tow module or tow bar, we recommend that you switch the system off when you attach a trailer.

When the cross traffic alert detects an approaching vehicle, a tone sounds, a warning lamp

illuminates in the relevant exterior mirror and arrows appear in the information display to show which side the vehicle is approaching from.

If the system malfunctions, a warning lamp illuminates in the instrument cluster and a message appears in the information display. Have your vehicle checked as soon as possible.

Note: If arrows do not display, a message appears in the information display.

Note: In some conditions, the system could alert you, even when there is nothing in the detection zone, for example a vehicle passing further away from your vehicle.
