How to tell if ZM model
 

2003 Protege5

Working on the timing belt and water pump with my son. Shop manual lists instructions for ZM model. (If ZM model do this...). How do I determine if I have a ZM model?

OK, I figured out the car is the FS model. The shop manual describes repair instructions for two models, the ZM and FS. What I can't figure out, and at this point is an academic question, is how to determine that from the actual manual?
