Morse code sounding beeping after start when below freezing

I normally park in a garage, but both times I've parked outside and it was below freezing when I started the truck it has done this. It lasts for a few m

inutes and then stops. No error lights on the dash.

I just cranked mine up this morning, and it was 15º. I've never heard it.

That’s the AI complaining that’s cold outside

Video doesn't work, but just going off of your description and from what I've experienced (albeit just a few chirps when I start the truck up in the mornings) I'm going to take a stab in the dark and say it's the belt squeak that seems to be normal.

It sounds like a touch tone phone. What happens if you turn off the carplay or android auto?

Not sure, but I'll try that next time. It would be weird to me that that would be the cause given the temperature correlation. Also of note, having the stereo on/off doesn't affect it.

I agree with @maxx075 - a slipping belt is a lot more likely when it is cold outside. In your garage it is just warm enough, but out in the cold, it might squeal a bit until the belt warms up and then it goes away. As long as that is the only time you see it, I wouldn't worry.

Got the video to load on my phone, desktop wouldn't load. Definitely doesn't sound like a belt watching it now. Like somebody else said, it sounds like a touch tone. Weird. I've never heard that before lol. Belt slipping that I've encountered sounds like a chirp or a cricket.
