Hey by’s,

After not using my car for about 3 weeks, I started it and it broke down in the middle of the highway. Had to tow it to a mechanic.

Since then, the handbrake isn’t working properly and I keep getting a high temperature warning on the dashboard. (Honda Civic)

I’m not very knowledgeable about cars. I checked the coolant and this is what it looks like when I open the cap.

Should I just refill the coolant myself or is it better to get a mechanic to take a look?

Appreciate any advice 🙏
