You do not have to change out both unless they are worn below minimums. The FSM states a value above the minimum that when your changing out the pads the rotors should also be changed.

I haven't recently priced rotors, I've just changed the pads and all was well, rotors were above minimums. Sometimes it's more cost effective to change the pads and the rotors vice having the rotors turned.

Personal choice i guess. The FSM doesn't say you can't turn the rotors.
