That surely isn't so. All US cars have jacks. I think you need to have a visit with your dealership. I'm sure it should be there. My car had a large heavy paper "sign" that stated some facts about the car including what items it was shipped with such as the jack, compressor, front license plate bracket (missing), manual, etc. Did you run across such a thing in the boot when you bought the car?

(Mine was and is still missing the mystery tool ).
