Adaptive cruise control
So I looooove this feature but can’t figure out one aspect: how long does the vehicle remain stationary before the cruise goes onto standby? (once in standby you need to nudge the resume, speed or accelerator to get going again. )
It seems normal function is that when stopped for 3 seconds it will go into standby. But sometimes it stays on. I haven’t figure out why. Passing thoughts: could it be if you’re on a dual carriageway it stays on; could it be something to do with how many times you’ve already resumed within that stretch; something else? Anyone else know or have ideas/thoughts of their own?

having used it quite a bit it is either 3 seconds or longer. I think its only longer than 3 seconds when traffic assist is in operation ie ACC and lane assist also on .
you can press the gas pedal or the res switch on the wheel to move again. that seems to be take on it so it depends what mode it is in |

Aha. Ok so both acc and lane assist on means longer than 3 seconds? I assume that means proper lane assist - ie with the lines green rather than just the ‘follow Car in front’ mode.
I can’t clearly remember if I’ve looked out for that but will do from now on. Thanks AP |

Traffic jam assist Works whether their are recognised lanes or not. Manual isn't clear to me to be honest .
Best try but if in traffic might as well have lanes assist on aswell as acc |

Technical training docs are little bit clearer as they are talking about how the system works in different conditions.

So it’s not linked to the lane assist. I think it’s the dual carriageway/motorway thing. But not only that.
Where are the tech training docs on this topic...? |

it might also be distance based as well potentially so at slower speeds it is longer before you get a prompt to put your hands on the wheel.
Bottom line is , it is what is it and can't change it so have to just accept it how it is. of course at motorway speeds although you are prompted to put your hands back after about 3 seconds you can decide not to but after 30 seconds it will disengage. |

No that’s not what I mean. It’s not about how quickly your hands need to be on the wheel. It’s about the 3 second vs 30 second timeout on the stop and go function. Sometimes it’s one and other times it’s the other. I haven’t fully clocked when is when but dual carriageway/motorway has something to do with it.

ah ok, yes I still think its down to whether traffic assist is in operation as well.
If Traffic assist is in operation then it will wait longer and start again without any input. It's not very clear though. In terms how I use these systems, personal preference but I tend to do this when I want the automatics to help out and am not driving fully manually. Motorway ACC or ACC+LaneAssist Heavy Traffic ACC+Lane Assist |

One warning. If you are pulling into a stop sign behind some other cars, once the car in front of you moves your car will want to move as well if you are within the seconds from stopping. That could be dangerous if it is a four way stop.

Yes. Must be vigilant but as a daily commute car in heavy traffic it’s really great! You (generic you) just need to learn how to use the tools and not expect it to do magic.
