Somebody in the UK forum asked what would happen if you’d press the Start button while driving. Time for an experiment.
- Pressing once: only thing happens is Cruise Control tripping off ;
- Long press: nothing happens;
- Five short presses: “ignition off”. Car starts coasting. No abrupt bleeding of speed. Brake servo remains primed, as is power steering.
To re-engage, let it coast for a few seconds, then short press again. It will do this even while the gear is in D!
One small software bug was detected while testing: the dashboard consumption / regeneration arc is gone and the “READY” label won’t go away until a “proper” cycle is done.
All testing was done done on the motorway, 100 km/h, 2013 Q210.
