I find this all a bit concerning. In 8 years of motoring with 3 Jazz cars, I have never once had the Active Brake System kick in. All settings are, all as far as I know, set to default position.
Certainly the Collision Warning operates from time to time, mostly when I drive into my garage, but that is all.
Maybe I should check that the system operates as it should, although I can certainly live without it
A merry Christmas to all.
