My car is low in DEF fluid. But I don't know where the DEF tank is located. I checked under the hood, gas compartment. Under the spare tire in the trunk but I did not find it. Maybe I just don't know what it looks like because it's an old vehicle.

You selected the year of 1994. Is that correct? DEF systems did not exist back then so I am wondering what we got wrong but that would explain why you can't find it. Can you get a picture of what this message is saying and we can go from there? Thanks
