I do it all the time without any ill effects. I had a discussion Monday with a Service Writer at my dealership (having a CEL associated with the DC converter which is somehow linked to the start/stop feature) and he mentioned that they get a significant number of complaints regarding the intrusive nature of the feature. I mentioned that I shift into "L" and then run the range to 9; he indicated that is an acceptable method of over-riding. Also, the owners manual states that is an acceptable method of configuring the transmission when towing--and the owners manual has no notes, cautions, warnings, etc regarding employing that method of use.
