Mnemonics
Imagine opening a door and stepping out (out = aus) of a bus or train; the 'aus' prefix is like 'out' in English.
Sounds like 'out + stay' — think of going out and no longer staying on the vehicle.
Notes
Aussteigen is a separable, intransitive verb commonly used with public transport. It forms perfect tenses with the auxiliary 'sein' (e.g., 'ich bin ausgestiegen'). The separable prefix 'aus-' is detached in finite forms: 'ich steige aus'. Intransitive verb; passive forms are not applicable because there is no direct object to become the subject of a passive construction.
