Don't need car expert to know this, it is just the basic knowledge a car owner should know.

There is a thick book came with the car which is called user manual, you can learn many thing from there and those concerns you raised is all stated in there.

I read every single page of it and finished the whole book, and I did not become a car expert upon finishing the book, I just become more well aware of what the car is capable of and how to use those functions correctly, be a responsible driver and a car owner, these help you a lot along the way especially like troubleshooting or getting potong leher by foreman out there with their foreman tukar skill.

Give it a good read, it is important.

If you don't understand specific part mentioned in the manual and posting it up, I think people will be more willing to help than trolling.

Just think like this, what makes one think they deserved to be spoon fed without reading the manual while those who read the whole book need to spend their time and efforts going through the details?
