2021 Ford F-350 Owners Manual - Traction Control



Traction Control

The traction control system helps avoid drive wheel spin and loss of traction.

If your vehicle begins to slide, the system applies the brakes to individual wheels and, when needed, reduces engine power at the same time. If the wheels spin when accelerating on slippery or loose surfaces, the system reduces engine power in order to increase traction.

WARNING: The stability and traction control light illuminates steadily if the system detects a failure. Make sure you did not manually disable the traction control system using the information display controls or the switch. If the stability control and traction control light is still illuminating steadily, have the system serviced by an authorized dealer immediately. Operating your vehicle with the traction control disabled could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death.

The system automatically turns on each time you switch the ignition on.

If your vehicle is stuck in mud or snow, switching traction control off may be beneficial as this allows the wheels to spin.

Note: When you switch traction control off, stability control remains fully active.

Note: For additional information on the traction and stability control systems. See Using Stability Control (page 229).

When you switch the system off or on, a message appears in the information display showing system status.

Use the traction and stability control switch on the instrument panel to switch the system off or on.

The switch illuminates when traction control is off.

When you place your vehicle into

four-wheel drive low mode the traction control disables. Traction control resumes full operation when you put your vehicle back into two-wheel drive mode.

The stability and traction control light:

    Temporarily illuminates on engine start-up.
    Flashes when a driving condition activates either of the systems.
    Illuminates if a problem occurs in either of the systems.

The stability and traction control off light temporarily illuminates on engine start-up and stays on

when you switch the traction control system off.
