Here at our Land Rover Southampton location, we spend time helping our customers to find ways to keep their vehicles in good health. In terms of keeping vehicles healthy, there are obviously many possible areas of focus. That said, one critical automotive feature that is often overlooked in the quest for vehicular longevity is the 4 x 4 system. Most 4 x 4 transmission systems are sensitive and complicated pieces of machinery, and as such, it can pay to know when and how to use these gear ranges.
