Air conditioning system with refrigerant R134a - Edition 10.2014
• While the engine is running and with the air conditioning sys‐
tem set to maximum cooling capacity:
Set maximum cooling capacity of the air conditioning system
Setting on the control and display unit for air conditioner Clima‐
tronic - E87- :
– Pre-select operating mode "auto" (AC compressor switched
on).
– Set temperature pre-selection "LO" for driver and passenger
side.
Setting on the manual heater control, air conditioner Climatic:

– Rotary switch for fresh air blower - V2- on position "4".
• If the radiator fan (if the fans run) runs -V7- (min. in stage 1).
Note
On certain versions, the fan is only switched on after the pressure
in the refrigerant circuit has exceeded a given value.
• The AC compressor is indeed driven ( air conditioner magnetic
coupling - N25- is closed, it is possible that the existing belt
protection in the AC compressor belt pulley is not damaged).
