Selectable Driving Modes

2021 Ford Transit-350 HD Base, Van Cargo Extended, 3.5L Eng VIN 8, AWDSECTION Selectable Driving Modes
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The dial switch located on the ATCM (also known as the 4-wheel drive mode select switch) allows the driver to select between 9 modes; deep snow / sand, economy, mud / ruts, normal, rock crawl, slippery, sport, trail or tow-haul. These driving modes alter throttle response, transmission shift patterns, EPAS feel and stability control intervention thresholds. Rotating the switch sends a voltage signal to the ATCM, the module then sends a message to the GWM over the HS-CAN1, and the GWM relays this message to the ABS module over the FD-CAN.

Some drive modes reduce traction and stability control performance and the stability-traction control warning indicator illuminates in the instrument cluster.

  • Baja 

    : used for high speed off-road terrain.

  • Deep Snow / Sand 

    : for off-road driving on soft, dry sand or deep snow. This mode optimizes accelerator pedal response, traction and stability controls to help maintain forward momentum.

  • Normal 

    : delivers a balanced combination of comfort, control and handling.

  • Slippery 

    : for less than ideal road conditions such as snow or ice covered roads. Used for crossing terrain where a firm surface is covered with loose, wet or slippery material. Slippery mode lowers throttle response and optimizes shifting for slippery surfaces.

  • Sport 

    : for sporty driving with improved performance handling and response. This mode increases accelerator pedal response and provides a sportier steering feel. The powertrain system holds onto lower gears longer, allowing the vehicle to accelerate faster.

  • Tow-Haul 

    : improves transmission operation when towing a trailer or a heavy load.

  • Rock Crawl 

    : for off-road driving and optimum rock-climbing. Rock crawl mode engages the electronic locking differential and optimizes the throttle and transmission response to provide additional control of the vehicle.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
