Hi there, i'm new to the forum.
I should be getting my new ST in about a week, one of the options i chose was ESP. I've heard different reviews on ESP (good, bad, etc,,), so i was wondering if there was an ON /OFF button for the ESP

Hi there, welcome to the forum mate.

I haven't personally got ESP, but yes there is a button to turn it off. Thats one of the reasons I didn't bother going for it, since I know I'd be that tempted to switch it off most of the time, and the one time I'd need it it wouldn't be there for me.

Thanks for the answer. I'll prolly leave it off so the GF doesn't think that the car will know what she's thinking ^^

I have ESP on mine and it works by switching on when you start the engine every time. You then have the option of turning it off if you choose to. You have to hold the button in for a second or two for it to register so that you don't switch it off by accident.

Personally I don't find any performance hinderance by having it turned on, so I leave it on all the time.

Hope that helps
