Well it looks like you have a few options as it uses multiple belts. If you have one belt that is failing you would be better off changing all three just to avoid trouble from the ones you did not replace.
Length wise the belt that drives the AC (6) is 945mm long the one that drives the alternator and water pump (3) is 990mm long. The V belt that drives the power steering (4) is 673mm.
