Pressing the start/stop button at speed.
Hello,
Whilst I was moving forward slowly the other day in D, I pressed the start/stop button and the car immediately shut off. Wasn''t turning or going fast so not an issue...
So I was wondering what would happen if this was done at a higher speed? Has anyone done it?
I read that you have to hold it or press twice in 2-3 seconds (I think) but this is not what happened to me, just a quick press stopped the engine.
If this did happen at say 70mph, like a crazy passenger pressed it, I am thinking the brakes would require more effort to pull up, you might get a car in your boot, the steering would be "non-powered" but what about the steering lock - would that engage? if you are taking a bend.
Anyone tried it, have experience of it or are super brave or own an airfield to test it?

I suspect, but don't know, that it would be inhibited at higher speeds for the reasons you mention, the same as the park brake if just flicked on .

for safety reasons you wouldn't be able to?? it would be crazy if this function was available at high speed...
I can't speak for the Discovery but with my Audi A4 once travelling over a certain speed not sure what but we'll say 15mph. The start stop button would become inactive, as would the electronic brake.`

Yes, I think that might be the case for a quick press. I am sure I read that a long held press would shut it off regardless of speed.

If it did, the normally park mode is engaged automatically, at least on 8 speed models, that would not be goodJoined the BMWX5 45e group

Give it a go and let us know how you got on
Such an important & scientific experiment for the good of the group needs to be explored

Have also been told that if your doing 70mph in D and shift to R the gearbox just ignores you, I assume it stays in N. Apart from putting the reverse lights on. No Mad Max reverse gear stops but would give the tailgater something to think about.

I have previously tried pressing the start button whilst moving, but was probably only 10-15mph. The engine shut down, and wouldn't restart until I was completely stationary. This I considered dangerous and made mental note not to do it again. Think I'll try it again at 20 and see what happens
(we have a long farm lane down which to test such things)
The park brake from speed is 'entertaining' everyone should try it.Long succession of Disco's since 2001...

How about........................All 3
At 50mph
1. Wack it into Reverse
2. Hit Stop/Start
3. Yank EPB
May as well, as sooner or later your getting SCS anyway

Might try it in my wife's while she isn't looking...time for a change!
Looking on the internet they (the cars they were using) do shut down after a long press at speed. Don't go into P though. That would be BAD.In today's world, if you contribute something, you don't contribute enough. If you contribute nothing, you receive everything.

Interesting. A few times, I’ve been stopped with the gear selector in neutral, and decided to stop the engine.
The start/stop button didn’t work, and I got a bong, and a message saying the car wasn’t in park.
But, that’s the gearbox in neutral, not drive. Not ever tried that!
