You can download the Owners Manual from
(Last time I checked they had the AUII owners Manual There).
I dont know a whole lot about the Smartsheild system, but I think they came out on the AUII Models, although it is possible that there was a carryover period.
Umm, the only other way that I can tell that you have smartsheild is from the Keypad, (It has a Panic Feature).
Also Smartsheild has the Dual Stage Unlocking, (I.E. Pressing Unlock, and the Drivers Door Only will unlock, pressing it again will unlock all the doors.)
Also, I think the Instrument Cluster Warning Jewel actually says Smart Sheild, not Smartlock.
Mind you I havent been inside an AU for well over a Year, so I am probably very wrong about all this
Hope this helps a little ???
