Top dead center is the highest point reached by piston N1 during the compression stroke.
Piston N1 is located at the front of the engine on the side of the timing belt.
1. Disconnect the negative battery cable and, if necessary, remove the spark plugs.
2. Remove the outer timing belt cover.
3. Rotate the crankshaft so that the timing mark (1) the camshaft sprocket is aligned with the slot in the back cover of the timing belt, and the mark (2) the crankshaft sprocket is aligned with the slot in the oil pump housing.
4. When the marks are aligned, the N1 piston is at TDC on the compression stroke.
