I had to do some very sudden braking yesterday. I think I actually beat the auto reaction which was pleasing, but that may have been because the car was at the brow of a hill and pointing upwards. Anyway no harm done. But what did take us by surprise was that the hazard lights automatically turned on.

I had no idea that happened and in my three years on the forum I can't recall it being mentioned. (no doubt someone will prove me wrong)

I believe it's one of those 'mandated by a committee in Brussels' requirements on safety grounds. I had it activate when I did three or four emergency stops in a row to dry and clean my brake discs after the car had sat for a week in the rain.

In winter I now and then brake hard in order to keep brakes fit. The hazard lights trigger and they keep on flashing for a while. It's embarrassing to drive with them flashing.

Same behavior in the US. Described in the manual.

Well well - maybe that should be added to that wonderful thread with the title like "I never new it did that!" [can't find it at the moment.]

You don't have to brake hard to scrub the mechanical brakes, just pop it into neutral so that they're forced to do all the work. A few normal stops in neutral is all it's ever taken to get mine clean again.

That's where I wanted to put it, but I couldn't find it either.

yep its a G sensor i believe, and they turn off automatically once you start accelerating again

you will find other little things like the Cruise cuts out if ABS / Traction control cuts in (eg in poor weather like snow / standing water)
