Kia Cerato 2018 Problems

It’s not available on the current car. You have to wait for the new model, which launches in a couple of months.

No, there’s nothing built into the Cerato that might assist you in finding your car.

All Kias sold in Australia and built after 1996 can use E10 fuel. But your car will be just as happy on standard ULP with its 91 RON octane rating.

You won't notice any difference between the two fuels apart from perhaps a slightly higher fuel consumption when using the E10. That's because the ethanol content of the fuel has less energy in it than normal petrol. But there's really not much in it and the extra E10 you'll use will be offset by the cheaper per-litre cost compared with ULP.

The fact that you've used E10 will not alter the retained value or desirability to of your car to a potential buyer one bit.

I doubt that it is intentional, particularly as they’ve offered to try and buff it out for you.
