Quick toggle between ACC and TJA

[tashgraheme]

Sorry if this is old news, but I've just discovered that if you press and hold the steering wheel button on the steering wheel (the one that turns ACC/TJA on and off), it toggles between ACC and TJA mode. This is really handy and saves having to come out of Apple Car Play and dig into the menus to do it, if it's playing up.

Although I'm hoping that the SC007 update that's being appied to my car right now will stop it playing up...

This has been reported a few times. I'm not sure how long the functionality has been there though - I first noticed it after I got the ACC update in November 2023, but as I hadn't ever tried it beforehand I can't say whether or not that functionality has always been there.

Indeed, I hadn't realised you could do this until I saw another post on this forum about it. Handy to know, however.

Need to try tomorrow, but does it also cycle the speedlimiter?
Pet peeve is that it remembers to be in limit mode, rather than ACC... but always defaults to off.

Sadly it does not (cycle the speed limiter that is)
