It happened twice on the drive to Hermiston, Oregon from Yuma, Arizona. I think the first time I had started the engine and set the idle up to about 900 RPMs to get the air built up faster after dry camping overnight. I don't remember if I reduced the idle before pushing the D button. It would be irregular for me to not press and hold the foot brake before de-actuating the parking brake and pressing the D button. Pressing the foot brake automatically returns the engine to idle speed. So... I don't know for sure if the engine was at its normal idle speed of about 700 RPMs. The second time we had to stop in line on US395 South of Burns Junction for road crew maintenance. I think I shut down the engine because the pilot-car had to return from the other end of the one-way traffic section... about 10-15 minutes. I started the engine, de-actuated the parking brake and pushed the D button and a 6 flashed, then pushed the N button, then again pushed the D button and a 6 flashed again, then pushed the N button, then pushed the D button again... and off we went. I am pretty sure the engine was at normal idle speed this time.
I do not remember seeing any dash lights on but I don't remember looking for any either. Many of my dash lights are hidden behind the upper curve of the steering wheel... so unless I lean to one side I will not see most of those dash lights.
