Only holding by the brake pedal, if I take my foot off, in theory if I was on a incline it would roll back. I've tried pushing hard on the brake pedal but to no avail. I just turn off the ignition with first gear selected as I've done in every car and the handbrake automatically comes on.
One thing I have noticed with all this electronic wizardry is I cannot put the car into just first gear with no handbrake, we live in a very wet and damp part of the country and if the car is left undriven for just a few days to a week the brake pads stick to the discs, my other two cars all have just the gear engaged and no handbrake, they can sit for weeks or months and no binding/sticking.
Something I'll have to live with I guess.
