Note: Do not operate the air conditioning system if it is known to be short of refrigerant, as this may damage the compressor.
1 The only operation which can be carried out easily without discharging the refrigerant is renewal of the auxiliary (compressor) drivebelt. All other operations must be referred to a Fiat dealer or an air conditioning specialist.
2 If necessary for access to other components, the compressor can be unbolted and moved aside, without disconnecting its flexible hoses, after removing the drivebelt.
Warning: Do not attempt to open the refrigerant circuit.
