Hold during Autopilot?

[jmnieves]

Took out my MS today to test out the new update. When I was stopped at a light (with a car in front) I noticed the hold "Hold" above the speed limit, never noticed that before.

Once the car in front started to move, I had to press the accelerator to reengage AP.

Anyone else noticed this? If so anyone know why?

This is covered ad nauseam in this forum so I’ll answer before someone yells at you to use the search bar.

That happens when TACC senses something moving between you and the car in front of you when stopped (like a pedestrian). For safety, the car will not engage motion without driver input

Edit: and I’m going to anticipate your response: “nothing moved in front of me”
Doesn’t matter - all that matters is that TACC thought something moved

That's interesting. Thanks for the info! I've tried to find the answer to this and haven't been able to. Thank you!

Odd, I did a search on hold and AP and nothing came up, those threads must have been archived. In any event thanks.

I've actually noticed that if I engage AP too close to a stopped car in front of me, or if it otherwise ends up getting too close (e.g. it didn't see the car at first and then saw it and stopped short) then it will go into Hold as well.

^THIS^

9 times out of ten when it happens to me is because of this...

This is what happened in my case. Thanks for clarifying!

I had the mystery HOLD happen on the last FW, but on current FW I noticed that while at a stop using TACC, HOLD appeared briefly on its own then went away without me having to depress the accelerator pedal.
