I have a 1997 Subaru Outback. I recently was off road in the mountains and woke up to 14 inches of snow. For the first time I chained up my fronts and worked my way back to logging roads and then down the mountain. When I was telling a friend about it the next day, he asked if I put the FWD fuse in. I checked the owner manual and it did not mention changing to FWD. It indicated the following:
Driving on snowy grades or icy roads may require the use of tire chains, to which case put the chains on the font wheels only. Use only SAE class S type chains that are of the correct size for your tires so as not to damage the vehicle body or suspension. When driving with tire chains, drive at speeds below 19 MPH.
Is it required or is the any reason one should change FWD? At these speeds and conditions, it seems like the last thing you would want to do.
