How to turn on active cruise control?

[Sophie911]

I've had a Ds3 for a while now but can't figure out how to turn in the active cruise control (it gives me a warning every now and then saying the ACC radar is dirty) so it has it.

When turning the CC on and setting a speed, it just keeps getting closer to the vehicle in front rather than being "active" and keeping a set distance. I can't find anything about this in the book

I'm pretty sure DS3s don't have active cruise control, unfortunately. The radar you're getting messages about is for the active city brake.
