First of all the vinegar solution with warm water used with a soft,clean towel completely cleaned the stains on the plastic panel at the back, so thanks.
Now I have a problem with the Automatic climate Control. According to the owners manual, once you program it to certain temperature, the cooling function starts also automatically.
I set the temperature on 19 degree C ( that's metric ) and the outside temperature was more. Then I started driving and for more than 20 minutes, the cooling function did not start automatically. I almost started to sweat but wanted to test the system so waited longer but still the cooling function little green light with the little snow drop sign stayed off. Finally, I gave up and turned it on manually. Is this a malfunction or do we always should turn the cooling function on/off manually?
