Hiya RPM
if you can get yourself a copy of the handbook (i got mine via E**y)
I know its available via RAVE but the handbook fits nicely in the glove-box & is very handy for in-set reference on say the various locking modes etc
as mentioned RAVE is available from various downloads sites and is really good
If your taking ownership of the vehicle without the handbook & /or service book chances are you wont have the numbers covering the vairious systems for the vehicle RKA main no / radio no etc etc
what i did on taking pocession it take the vehicle around to the local main dealers and say i want all the code no`s & all the identification nos ect for the vehicle plugged it in & then gave me all the info and charged me 30mins labour for the work
well worth it if only to get the piece of mind to know that its there when needed
