Here are the marks that you need to use.
That is correct once you do this they will line up. The half notch is a guide to get the sprockets to line up, here is a much better reference. You should be able to take a straight edge across the marks, once the tensioner is released. Roll the motor over two times by hand and verify the timing marks are aligned.
CAUTION: When aligning crankshaft and camshaft timing marks always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed. Damage to valve components may occur. Always align timing marks before removing timing belt.
NOTE: The crankshaft sprocket TDC mark is located on the trailing edge of the sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause the camshaft timing marks to be misaligned
CAUTION: If timing belt was damaged due to incorrect tracking (alignment), the belt tensioner assembly must be replaced. Refer to Timing Belt Tensioner Assembly Removal and Installation procedure in this section.
CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.
NOTE: A new tensioner is held in the wound position by a pull pin.
