Ok then what's the idea of the switch on the right hand side of dash with a diagram of the 4wd? Is this where you choose the Tarmac, Gravel, Snow -setting? What do these setting mean, are they a way of changing the drive bias to the front wheels/back wheels or 50/50? Any ideas? Do these settings change the suspension settings i.e Gravel = softer setting? Or is it a load of old [email protected]@cks?
