2004 Scion xA power steering belt jumps the pulley

Power steering belt keeps jumping off the pulley. What can I do – torque it tighter?

Check your belt tensioner, it may need replacing. Also sight down the pulleys to insure they are in-line (in pane) with each other. Check the crankshaft pulley to make sure the pulley hasn’t moved in or out. Balancers have rubber in them and it can fail causing the pulley to move.
