The handbook says:
But reality is a little different. The car's warmed up via the main heater. The front demister is activated, so the windscreen is clear. The seat heater seems to be activated, but I suspect only if they were turned on when the car was parked. I've never seen the steering wheel heater activated, but I will live. What is really annoying is that the rear window demister isn't activated. I suppose it's possible, although the manual doesn't even imply, never mind say, this that the temperature threshold for the rear heater is lower than for the front. But it's a real pain: what happens with pre-conditioning is that the car gets warm and slightly damp inside, which steams up the rear window, and which is then slow to clear because the rear demister isn't the world's hottest.The following functions also operate according to the temperature:
When it is warm outside:
• The air conditioning is activated in recirculation
When it is cold outside:
• The heater inside the front screen* is activated as
• The rear demister is activated.
• The seat heater and heated steering wheel* are
Does anyone have experience of this?
