I have an "add coolant" message on the dash when I start the car. I looked in the manual and it referred me to the dealership or a website that is literally intended to confuse the reader. Is there a specific mixture of water to antifreeze that I need to add to this car?

You'll have a large capacity of coolant , the level will be down a faction of that capacity .

Top up with water, without fear of dilution .

Distilled water.

If you have low coolant check to see if your leaking coolant it could be a very small leak like a couple of drops.. if you do then that's a different problem you have and that's regarding your turbo coolant hose as mine did the same drove it like that for couple months till I realized I need a new hose as they heat up and a small leak happens over time. Check In the morning under motor If there's a couple of drops
