ACC "Ready to Start" timeout?

Post by RobM » Wed Jun 09, 2021 8:00 am


I have a first edition, which has now seen all software revisions up to 2.1. Throughout all of the software upgrades, I've never noticed any change to the timeout which the ACC system uses before refusing to re-start in traffic.

[Scenario: you follow a traffic jam in ACC mode, which brings you to a complete halt. You get the message "ACC: Ready to Start" (or something very similar). If the traffic moves on within a certain timeout period, the vehicle will re-start from rest. If not, the message disappears, and it's up to you to re-start the vehicle]

Here's the question:

I had a Pro edition as a courtesy car, and the timeout was significantly different to my own vehicle's. Mine uses something close to 10s as the timeout. The courtesy Pro edition had a timeout of approximately one minute. A 6x difference. Yet I can't find any way for a user to set this, and the difference can't be software revisions, as mine has had all software revisions either side of that installed in the courtesy Pro edition.

Can anybody shed any light on that?!

Mine times out at about 10 seconds - unchanged since I got 2.1. I can't see any way of changing this time.

Mine is about 10 seconds. Also after about a 2 minutes stationary the parking brake comes on and you have to reselect drive.
