Timing belt replacement on 2004 Mitsubishi Galant

I still have the balance of my power train warranty in effect and want to know if I don't change the belt at the
recomended 60,000 miles and it breaks later will this negate my warranty.

If the service guide recommends changing the belt at 60,000 miles and it isn't changed and fails, the repair will not be under warrenty
