Moin, we have been calling for a week a Hyundai Santa Fe from 2005 our own (V6 2.7 l, automatic, autogasanl.). During the test drive we noticed that the cruise control does not work. On the steering wheel there are 4 keys: “on/off”, “cancel”, “set” and “reset”. The cruise control cannot be activated by the “on/off” button; the “cuise” display in the amaturary board does not light up and there is also no speed “set”. “, so activate the cruise control while pedaling the brake at the same time, which does not work. The fuse is OK and all the buttons work (measured). Can you help me further what I should check next, or where I can find the control of the cruise control? Thanks for your help David
