Here we got about the first experience in some traffic jam with TJA on.
First I have RTT on, so you see immediately where the traffice is flowing and where not. Note it tells me the delays in minutes. For me this is new, so really nice and very accurate!
Then to turn it on use the smaller button on the bottom right.
if not on the high ways you will get the message that it will only work on the highways (or Autobahn).
here in German, circled:
So get on the Autobahn, here we go, it will activate warning it will work only for speed up to 40 km/h:
Now hope for a jam, where you go below 40km/h, now fun starts:
1) Set your cruise control to whatever speed (can be 120km/h), if the TJA was activated it will automatically pop in, once your car slowls you down automatically to below 40 (or whatever the car is driving in front of you).
once you are below 40km/h the steering pops in too, showing up with the little steering symbol between the lines ... so now just keep your hands on the steering wheels, otherwise you get the warning on the HUD and also in the control panel ... now enjoy the traffic jam and relax, it works like a charm.
I did not get into a full stop jam yet, to see what happens when you stop ...
