2.4 L XRS has an idler pulley (auto tension)
1.8L base, ce, le, xle, s hase manual adjustment by the alternator
for the 1.8 L you can adjust your belt by loosening the two bold holding the alternator and tightening the adjusting bolt on top. Its easily accessible when you pull the engine cover off. If you don't know what too tight or not enough tight is get it done by a qualified Toyota technician.
