you don't. This car has an automatic belt tensioner. The spring inside this part is probably worn out. You have to replace the tensioner.
It is also possible that the belt that is now on the engine has stretched beyond the point that the tensioner can compensate for; the belt may feel tight, but not be tight enough. In that case, of course, replace the belt. The Haynes manual has good instructions on how to do that, and the belt is not particularly expensive.

You don't tighten a serpentine belt. The tension is controlled by a tensioner. If it is loose, then the belt has stretched and needs replacing.
usually serpentine belts get their tension(tightness) from the belt tensioner
the belt tensioner does it by itself.short answer no
You don't. Serpentine belts are adjusted by a spring loaded device called a belt tensioner. If you belt is loose, then the tensioner is broken.
Theres a video demo on you tube detailing how.
the belt is automatically tensioned by a spring loaded tensioner.
You can change the serpentine belt by loosening the tensioner pulley. When the tensioner pulley is loose and the serpentine belt will become loose. Put the new serpentine belt on and tighten the tensioner pulley.
