Maybe you should stop bashing people for expressing they own thoughts or opinions on here. You should just probably called that one person who actually knows about Volvo and get answers directly. But to answer your question: there’s a parameter you can change it’s called Outdoor temperature warning. It warns when exterior temperature is in the range -3C to +3C. Warns either each time or only once per driving cycle. And it’s programmable. Booya!!
Now, if you read this post, I'm sure you read the previous posts as well. Even when I'm not driving a Volvo doesn't mean I have no clue. Think before you type and hit the send button.
