Your car has an automatic tensioner so unless there is something wrong with that or the belt you should always have the correct tension on the belt. My guess is there is either something wrong with the tensioner, the belt, or I think your car has two idler pulleys that can go bad and squeek. One is on the tensioner arm and one right by it. If belt dressing does fix the squeal, then check the condition of the belt, if that is good then you need to see why the tensioner is not keeping enough tension on the belt. How old is the belt maybe you ought to change it.

Replacing the belt on this car is relatively easy though harder than most vehicals, and you don't have to take the engine fan off like most say. I did on mine in a little over an hour with only a few cuss words involved. Hardest part of the job was getting the right wrench for the tensioner puller to pull it in so I could slip the new belt on. On mine it was an 8mm hex key. The pulley on mine is hydrolically dampened so have to pull it in very slow with significant pressure. Don't expect it to move immediately like the air conditioner tensioner puller.

If it turns out you have a bad pulley then you will probably have to remove the radiator, and engine fan to get enough room to change them.
