In the event of a breakdown
  Checking / adjusting tyre pressures 
  You can also use the compressor without injecting any product, to check and if necessary adjust your tyre pressures.  
   Turn the selector  A  to the "Air" position.    Uncoil the white pipe  G   fully. 
   Connect the compressor's electrical connector to the vehicle's 12 V socket.    Start the vehicle and let the engine run.    Adjust the pressure using the compressor (to inflate: switch  B  in position  "I" ;  to deflate: switch  B  in position  "O"  and press button  C ), according to the vehicle's tyre pressure label.    Remove the kit then stow it.    
        Should  the  pressure  of  one  or  more tyres be adjusted, it is necessary to reinitialise the under-inflation detection system.  For more information on  Under-inflation detection , refer to the corresponding  section.  
   Connect the pipe to the tyre valve.
