Hi everyone - Thanks for the info - I have placed my order and payed the deposit. Unfortunately I could only get the dark/black trim as I was told I would have to wait at least another 3 months and specially order the lighter trim if I wanted it. I am worried that the seats will get extremely hot when the car has been sitting in the sun with all the windows closed. I did find the info that I was originally looking for, on line. Apparently if the heater is turned on or an aircon temp that requires heating, is selected, the petrol engine will run to provide the heat. I did find a link that had all the owners manuals on line - that was very handy. The original salesperson that I was dealing with was new to the dealership and didn't know much about the Hybrid except how to start it and drive it. It is interesting to note that the people here, that have responded to my questions, have in their profile - interests "computers and electronics". Among other things I have the same interests having worked in electrical, electronics and computer trades all my working life. I do hope the 17 computers in this new car do not have to be rebooted too often - Ron smiles. Cheers Ron
