A question for you 4wd experts. Picked up my new 4wd SE 2 wks ago. I expect to be using the 4wd only in winter. My salesman told me I should run it in 4wd every now & then, even if it is necessary to run on dry pavement, to get lubrication to components that might go dry if not "exercised". Is this true and if so, how often & how far? Is there something on this in the manual?
Thanks for the help.
