My wife's 2009 CR-V cdti es got collected today and cery nice it is too. Being completely new to this model could I ask a daft question? Is this model permanent 4wheel drive? Reason for question is that I somewhere got the impression that one could switch from 2WD to 4WD a bit like an old Suzuki we used to own. No problem whichever but just curious as there is no obvious way to do it.
