This might be very stupid but I only have this car since 2 weeks (bought used). Today I noticed, that one of the red lights on the spectrum of the cooler temperature measure is on. It is the one closest to the H and there is no connection to all the white lights that rise until about the middle.

What does that mean? Do I need to refill fluid?

Thank you so much in advance. enter image description here
