What is the correct way to activate the air con.
Is it to press the "EC" button and turn the temp dials to blue?
As I don't have the manual yet, I'm not totally sure.
Also I've got heated seats, the button has two settings, If I press it up, one LED lights, If I press it down 2 LED's light up on the switch.
Is this for extra heat, or does it mean that the rear seats are heated too?
