Here's the full text of EO 617:

This is already in effect and just implements the ASEAN-AFTA free trade (tariff elimination) agreements made before.

For vehicles, that means that when we get CBUs from Malaysia, Thailand or Indonesia no tariff is charged upon entry here in the Philippines. In the same manner, when we export CBU vehicles (like the Focus & Mazda3) to the same countries (plus Vietnam and Singapore) they don't impose a tariff like before.
