2023 Ford Expedition Owners Manual - What Is Trail Turn Assist



What Is Trail Turn Assist

Trail turn assist can reduce the turning radius of your vehicle by applying the brakes to the inside rear wheel in low-speed, high steering-angle maneuvers.

Trail Turn Assist Precautions

Note:   Do not use trail turn assist on dry, hard surfaced roads. Doing so can produce excessive noise, increase tire wear and may damage drive line, or braking components. Trail turn assist is only intended for slippery, or loose surfaces.

You may hear noise from the anti-lock brake system while trail turn assist is active. This is normal operation.

Trail Turn Assist Limitations

Trail turn assist can only be used when the vehicle’s four-wheel drive system is in the four-wheel drive high (4H), or four-wheel drive low (4L) modes.

Switching Trail Turn Assist On and Off

You can switch trail turn assist on or off from the touchscreen.

Once switched on, trail turn assist will activate when:

  • Vehicle speed is less than 12 mph (19 km/h).
  • Vehicle is in four-wheel drive high (4H) or four-wheel drive low (4L).
  • Steering wheel is almost fully turned to the left or right.

You can deactivate trail turn assist by performing any of the following:

  • Selecting two-wheel drive high (2H) or four-wheel drive auto (4A).
  • Reducing the steering wheel input.

Trail turn assist remains on, even if deactivated, until you switch it off in the touchscreen. You can switch off trail turn assist through the touchscreen at any time.
