Cruise Control

[jdenver]

Hello ...

2021 Model Y newbie ... when on Cruise Control, car will continue through some greenlights but at others it will start to slow as if approaching a red light! Have to tap accelerator to override. Anyone else notice this? Is this normal behavior? I spoke with a Tesla technician and he didn't know what to say -- then he drove another Model Y and experienced the same thing. Thanks for the input.

Do you have autopilot, or FSD? I don't believe autopilot is intended for use with traffic lights - it is meant for FSD.

The OP talks about Cruise Control, which should not even care about stop lights ever AFAIK. A Cruise Control, even adaptive, tries to follow the set speed and slows down if there's an obstacle in front. That is all. It doesn't even follow lanes, you must drive.

I bought FSD so even when I am on cruise only without Autosteer, the car stops at every red or green or yellow light except when:

.There's a lead car that leads it through a green light
.I manually tap the accelerator to allow it to run through a green light.

Please read the manual regarding FSD. I know that's tedious, but this feature is advanced enough to where that is important. https://www.tesla.com/sites/default/files/model_y_owners_manual_north_america_en.pdf

Attached are two of the pages, but the rest are significant too.

jsight. Thanks for the link to the manual. That’s a lot easier than trying to read it in the car.
