24 Set air conditioning system to maximum heating capacity IMPORTANT This process serves to dry the evaporator. The success of the cleaning method is only guaranteed when the evaporator is dry.  
25 Set nozzle setting to footwell    
26 Place the atomizer (ultrasonic) in the passenger compartment on the passenger side, in the process attach the hose in the luggage net so that smoke which escapes is extracted via the footwell vents IMPORTANT The evaporator must be dried out before the atomizer is used (ultrasonic). The air conditioning must always be switched off during the following steps (observe operating concept A/C ACOFF). Route power supply for atomizer through front passenger window.  
27 Switch off the air conditioning    
28 With the engine running and the air conditioning system switched off, press air recirculation button, set to lowest blower stage and set temperature to "Min". IMPORTANT Observe operating concept A/C - ACOFF.  
29 Switch on atomizer (ultrasonic) IMPORTANT All the windows and doors as well as the sliding roof must be closed.
