All you have to do is press the start button without stepping on the brake. Press the "N" on gear selection and the tow in neutral will appear in dash display. Select ok then press start engine button again. The car is now in tow mode. As far as keeping battery charged just run a hot wire from coach to battery of car. Check for base plate availability of 4wd MKX models.

Can you give me some more details about the MKX towing procedure and how do you keep the battery charged while towing. Thx
