I use the tow/haul mode whenever I am towing. It changes the shift points and also does an extremely effective job at grade braking.

Additionally it locks the converter in all gears. Your transmission runs much cooler.

There are different modes.

Press once = No Overdrive

Press twice = No Overdive + Haul mode

Press three times = Overdive + Haul mode

Press again = normal with Overdrive

I noticed that after I cycled through the settings all I have to do is press once for it to toggle between normal and Overdrive + Haul mode.

Actually that is not right. The way it works is when you tap it (press quickly) it shuts the tow/haul mode on or off. When you hold it down turns the OD lockout on or off.
