Kia Sephia Camshaft Timing

There Is An Index Or Whatever It Is Referred To On The Outside Of The Lower Timing Belt Cover That Is Supposed To Be Used To Check Timing....

There Are Three Timing Marks, Which Do I Use To Align When Replacing The Timing Belt?

I Need A Diagram Of The Timing Marks On A 1997 Kia Sephia 1.8l. Ccould You Help Me Find One?
