I have just received after several delays my LHD 2007 320cdi from Germany . The owner’s manual is in German & I cant make head nor tail of it. Also cant find any on line info. The car has auxiliary heating & has a small remote control unit to operate the system. The remote has a window showing status, an on button , off button, plus two smaller buttons above these with no makings. I assumed the on would fire up a burner & warm up the coolant & also circulate warm air into the cabin. I also hope these systems can be timed to come on & off at preset times. Say half an hr before setting off for work in the mornings. I would be grateful if someone knows how these systems work could give me some advice on how to use it. Thanks in advance.
