All this talk about where things are located in modern vehicles puts emphasis on one very important issue. When you purchase or lease a vehicle, spend the necessary bucks to buy a complete set of shop manuals. Helms Inc. has them for almost any vehicle. A complete set, including actual schematics cost about $150 for the average vehicle. After some 30+ years of mobile operation, this is one item that is of paramount importance. As an added bonus, the last time I traded cars, I actually talked the dealership into including the manuals for no additional cost.
