Tow/Haul (Diesel Engine Vehicles)
WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The tow/haul switch is a momentary contact switch located on the end of the selector lever. When pressed, the Tow/Haul switch sends a signal to the PCM. The PCM makes changes in shift scheduling and TCC operation.
When tow/haul mode is activated, the following occurs:
- All forward gears are available.
- Shifts occur at higher vehicle speeds to improve vehicle acceleration, reduce shift frequency and increase coast braking capability.
- TCC is applied at lower vehicle speeds to improve transmission cooling and efficiency.
- Upshifts are temporarily delayed during hill cresting to reduce transmission ratio hunting and to prepare for possible downshifts while descending a grade.
- Engine braking is provided in all forward gear positions, D, 3, 2 and 1.
- A PCM strategy, known as grade braking downshift automatically provides increased coast braking to assist the driver in maintaining a desired vehicle speed while descending a grade.
Default is tow/haul OFF.
