2021 Ford F-150 Owners Manual - Blind Spot Information System

Blind Spot Information System

Blind spot information system detects vehicles that may have entered the blind spot zone.

Blind spot information system uses sensors on both sides of your vehicle, detecting rearward from the exterior mirrors to approximately 13 ft (4 m) beyond the rear bumper. The detection area extends to approximately 59 ft (18 m) beyond the rear bumper when the vehicle speed is greater than 30 mph (48 km/h) to alert you of faster approaching vehicles.

Note: Blind spot information system does not prevent contact with other vehicles. It does not detect parked vehicles, pedestrians, animals or other infrastructure.

Blind spot information system does not operate in park (P) or reverse (R).

The system may not alert you if a vehicle quickly passes through the detection zone.

Blind spot information system turns on when all the following occur:

You start your vehicle.

You shift into drive (D).

The vehicle speed is greater than 6 mph (10 km/h).

To switch blind spot information system on or off, use the touchscreen:

When you switch blind spot information system off, a warning lamp illuminates and a message displays. When you switch the system on or off, the alert indicators flash twice.

To permanently switch the system off, contact an authorized dealer.

BLIND SPOT INFORMATION SYSTEM WITH TRAILER

COVERAGE (If Equipped)

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 the sensors become blocked, a message appears in the instrument cluster display. See Blind Spot Information System – Information Messages (page 343). The alert indicators illuminate but the system does not alert you.

Blind spot information system detects vehicles that may have entered the blind spot zone.

Trailer coverage only supports conventional trailers. The system turns off if you select a fifth wheel trailer type.

Make sure the trailer width is less than

8.5 ft (2.6 m) and the length is less than 33 ft (10.1 m). If you input values higher, the system turns off.

Some trailers could cause a slight change in system performance:

Large box trailers could cause false alerts to occur when driving next to infrastructures or near parked cars. A false alert could also occur while making a 90-degree turn.

Trailers that have a width greater than

8.5 ft (2.6 m) at the front and have a total length greater than 20 ft (6 m) could cause delayed alerts when a vehicle is passing at high speeds.

Box trailers that have a width greater than 8.5 ft (2.6 m) at the front could cause early alerts when you pass a vehicle.

Clam shell or v-nose box trailers with a width greater than 8.5 ft (2.6 m) at the front could cause delayed alerts when a vehicle traveling the same speed as your vehicle merges lanes.

You can set-up a trailer to work with the blind spot information system through the touchscreen. When setting up a trailer, a sequence of screens appear asking for trailer information.

Select type of trailer screen - conventional, fifth wheel or gooseneck.

Note: The system only supports conventional trailers.

Do you want to set up blind spot with trailer screen? If no, the system turns off. If yes, the menu goes to the next screen.

Is the width less than 9 ft (2.6 m) and length less than 33 ft (10.1 m)? If no, the system turns off. If yes, the menu goes to the next screen.

Trailer width measurement. Measure the width at the front of the trailer. It is not measured at the widest point of the trailer. The maximum width at the front of the trailer the system can support is 9 ft (2.6 m).

Note: You do not need to enter an exact trailer width measurement. You only need to confirm that the width of the trailer is 9 ft (2.6 m) or less.

Trailer length measurement. The trailer length is the distance between the trailer hitch ball and the rear of the trailer. The maximum length that the system can support is 33 ft (10.1 m).

Enter the length of trailer. The default setting is 18 ft (5.5 m). Toggling up or down using the menu buttons increases or decreases the measurement by 3 ft (1 m). Select a length that is equal to or within 3 ft

(1 m) of the actual measured length. For example, if the actual measure length is 25 ft (7.5 m), toggle the length in the menu to 27 ft (8.2 m). The system setup saves when you enter the length of the trailer.

Note: If the trailer is a bike rack or cargo rack with electrical lighting, enter a length of 3 ft (1 m). Cross traffic alert remains on for trailers with a length of 3 ft (1 m) or less.

Note: The system requires proper measurement and measure entry to function properly.

When you connect a trailer to your vehicle, the trailer set up menu appears in the touchscreen. This menu allows you to set up a new trailer or choose from a previously set up trailer. A warning message appears and the system turns off if you do not choose or add a new trailer.

342

Note: The warning message may not appear until your vehicle reaches 22 mph (35 km/h).

When blind spot information system detects a vehicle, an alert indicator illuminates in the

exterior mirror on the side the approaching vehicle is coming from. If you turn the turn signal on for that side of your vehicle, the alert indicator flashes.
