Whist playing with my climate controls. I found that you can control BOTH temperature settings at once by either of the + and - buttons. I'm sorry if this is basic knowledge for everyone but having the car for over two years I've not come across this in my manual, or elsewhere, before - and being a little 'tidy minded' where things have to be equal!.. this saves me setting both temperatures the same manually. Theres no obvious way, by looking at my controls, to set the climate controls to move equally. If I simply press the left and right AUTO buttons together, the temperature range can be moved equally up and down by using either of the controls.
