Quoting from their FAQs:
If your obstruction violation is a result of a roadside emergency (e.g. stalled engine), you may be able to convince the MMDA or traffic enforcer to move your vehicle to a safe location at the side of the road and wait for an AAP tow truck to rescue you. Some members have who were in similar circumstances have informed us that MMDA enforcers allowed them some time to wait after the enforcers learned that they are AAP members. This, however, is not guaranteed to work all the time.

What if i was not able to convince them? did i just lose my opportunity to take advantage of my benefit as a member? hmmm...
