detailed explaination of how 4 wheel drive system works

[DougS]

G'day all

My first post

I was visiting a mate with my newly purchased 2010 Kluger and he asked me how the 4wd system works but I was unable to explain it beyond it being electronically controlled . I read of terms such as "active differential' "traction control" "ABS" "ESP" on the internet but can't find much specific to the Kluger

Can anyone describe how it all works together?

Regards

Doug
