On the subject of warning beeps, I've got a question about the "low temperature" warning beep. I'm confused about when it chooses to sound, and when it doesn't.
About 10 days ago it went "bong" for the first time, and it switched the multi-function display to the temperature, which was about 4 degrees. Since then, I've noticed that it sometimes "bongs" and sometimes doesn't. Often when I've got in the car in the last few days it has gone straight to low temperature but the bong hasn't sounded.
I'm just curious to understand its logic. One possibility is that it only bongs if the temperature starts above the threshold and drops below the threshold whilst you're driving. In other words, it doesn't bong if it was already cold when you turned the ignition on. This would make some sense; you already know it's cold because you've just got into the car from outside.
