Was anyone else caught out by the accelerator activated release, after picking up the car I was surprised to roll back on my first two hill starts. On checking the manual discovered that on touching the accelerator it releases the handbrake. My previous car a Qashqai didn't release until the clutch started to bite making hill starts a doddle. I have now had to change a habit it of a lifetime to not increase revs until I start to engage the clutch, whilst I have quickly got used to it on the flat @ slight inclines I still find it difficult on really steep ones without stalling. Is it OK to hold the handbrake release button up whilst revving as per an old fashion handbrake start or is it likely to damage the electronics?

The hill-start assist control works fine by me
If you have to stop on a hill then you Approximately have 2 seconds elapse after the brake pedal is released
That is more than enough time

That's what a Hold button is for if you really need it (p. 241 of EN manual)

I certainly do not get a 2 sec elapse on mine the slightest touch & it releases immediately. The Hold button does not help as that also releases on the touch of the accelerator straight away. Is there a separate hill start assist control I have seen no reference to one

There must be something in the user manual
Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting
on an uphill

How do you imagine it should work? I think it does how it's supposed to. Or do you want to work accelerator and brakes simultaneously?

As I said I am use to the release working on clutch engaging not on accelerator operation, I have read the manual but did not see any ref to 2 second delay or hill assist. My hold button which I use all the time does not operate the release any different to the hand brake. I have spoken to several friends regarding this, including an ex traffic cop. None of them had come across an accelerator release either

Well I hate to break it you but my last three cars over the past 6 years all had accelerator release.
And I am not sure why it's an issue to be fair? You find your bite point BEFORE you press the accelerator so why would you be rolling back?
I wouldn't ever want it the other way round to be honest.

It works fine for me. After reading this, I paid attention and even if I took my foot from the brake it didn't release the brake. Only when I pushed the accelerator. I think it was more than two seconds.
Hold is another function. It can also prevent hybrid version to start rolling when brakes are released. We all know that we don't have to push the accelerator to start moving.
