| Steptronic works as you state, and you can't mess it up because the computer will not execute shifts that don't produce logical useful results.
If you move to SD and then pull back once, the computer then displays the "gear" (1, 2, 3, 4, 5 or 6) it has selected for that speed in the speedometer where "SD" had been shown. You can then select up or down from there depending on what you want to do. There is NO concern about forcing it because it will only change if the new choice is logical for the speed you are driving.
This will quickly feel like the manual you are accustomed to.
Starts from a stop light will automatically be in "2" unless you select "1". I'm not certain it makes any difference, but try it and let us know. This is the kind of stuff we are trying to document. |
