Slightly OT: not to do with smells in Air con, but to do with the
above comment:
We had a Ford Galaxy, that had a similar warning in the handbook, just
before we sold it, we found out why.
Apparently, we hadn't run it enough, and the compressor seized.
Since the fan-belt drives this compressor the whole time (even when
the air-con isn't on), this was making a burning smell as the belt was
forced over a fixed pulley. Cost £1000 to fix (20% of the value of
the car). Another one from the Ministry of crap design.

There's an electromagnetic clutch between the pulley and the compressor -
so the actual compressor doesn't turn when not in use. It also cycles when
in use. So whatever seized was to do with the clutch.

My old Rover has a clever idea to make sure the AC is used - it switches
it on when you go to defrost, so will get used throughout the winter.
