Lately my Gas gauge say 1/4 tank left. Computer Say 0 kilometers to empty. Who is correct?
Or, how to "reset" gas calibration?

I would fill the fuel tank and determine how many gallons it takes - that will answer the question on zero KM to empty, or 1/4 tank left.

I don’t know how to reset the gas calibration.

Do you have the driver's manual? The steps should be spelled out for your vehicle & options.

You need to reset both of your trip meters. If you don’t reset them the average fuel mileage over all the miles is used to calculate distance to empty.
