leaves to ensure that the heating and cooling system operates properly.v
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!

CAUTIONWe recommend not smoking in the vehicle when the recirculating air opera-
tion is switched on. The smoke sucked from inside the vehicle is deposited on
the evaporator of the air conditioner. This produces a permanent odour when
the air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).
