How do you remove the auxillary belt on a citroen Picasso?

To remove the auxiliary belt on a Citroën Picasso, first, ensure the engine is off and cool. Locate the tensioner pulley, then use a ratchet and socket to relieve tension on the belt by turning the tensioner counterclockwise. Once the tension is released, carefully slide the belt off the pulleys, taking note of its routing for reinstallation. Finally, remove the belt completely from the engine compartment.
