Yea it will tell me but I'm old and things like checking the oil are something that I have always done. With my truck, I checked it 1 time just so I could say I did it.You may not even need to pull the dipstick if it has an oil-level sensor. Check the manual under 'messages'. Just depends on the year model.
It will tell you when it is getting low of oil or coolant.

I got a warning to check the charging system. I found out that meant the idler pully was broken and the serpentine belt was off and the truck will overheat quickly.
It takes some getting used to with all the built-in warnings. Mine even tells me the driver needs to take a rest break. Not sure what triggered that but I suspect it has to do with the lane control function.
