To disable the MDS, put your shifter from D to 5 (as displayed on the EVIC or cluster). With the console shifter, this is just one hit to the left. With the column shifter you need to push the +- button - one time.
Your trans will still shift up and down automatically through all the gears.
Tow/haul button is not the correct method.
Great post! Now to get my exhaust on and use it!
