Hi there, just bought a 2007 C4 Picasso and I love it! A couple of questions: 1) I can't get the hang of the heating controls. On my old Xsara Picasso Exclusive, it seemed obvious, but I guess the C4 I bought is more manual. Basically, what should the controls be set to when there is a lot of misting up of all windows? I have trouble with that. Also, does heat only come out of the side vents when the distribution control is set to 'side only'? 2) Keys. Both my keys show up as having a flat battery when I insert them into the ignition. I have replaced the batteries - CR1620 - and am still getting the same error on the dash display. If anyone could help on these questions, I would appreciate it! Thanks, in advance.
