       | 1. | Operate the hood to the open position to increase the light and make working easier. 
 
   
 
          
           
            | Note |  
            |

       |  | 1.a. | Release the rear seat backrest and fold it forward. 
 
 | 
     
    
   
   
    
     
      
       |  | 1.b. | Remove the cover over the emergency valve and open the valve approx. one half turn
        
         (A)
        
        .

       |  | 1.d. | Activate the fifth bow lock using the diagnostic tool set to UNLOCK and fold up the fifth bow. 
 
 | 
     
    
   
   
    
     
      
       |  | 1.e. | Push the wheel bolt tool through the hole in the covering on the right-hand side of the luggage compartment and into the link arm of the operating mechanism
        
         (B)
        
        . 
 
 | 
     
    
   
   
    
     
      
       |  | 1.f. | Unlock the soft top cover by pulling the tool backwards until the soft top cover lifts up a few centimetres
        
         (C)
        
        . 
 
 | 
     
    
   
   
    
     
      
       |  | 1.g. | Remove the tool, close the boot lid and open the soft top cover. 
 
 | 
     
    
   
   
    
     
      
       |  | 1.h. | Carefully fold down the soft top. 
 
 
          
           
            |

                        | 
                          There is a pinch hazard and danger of crushing if you let go of the soft top in the half-open position (when vertical). It will fall backwards or forwards, depending on its centre of gravity.

       | 6. | Open the emergency valve. Unscrew the reservoir oil plug and then retighten it to even out the pressure. 
 
 
          
           
            | Note |  
            | 
              This prevents unnecessary oil spill when hydraulic unit components are replaced.
