Vehicle manufacturers produce vehicles used for transportation in many different configurations using various different types of propulsion systems (e.g., engines or other powerplants). Most consume gasoline or diesel. More recently, manufacturers have increased production of vehicles having propulsion systems that utilize alternative fuels. These vehicles are sometimes referred to as alternative fuel vehicles. While a familiarity exists for the characteristics and precautions taken when dealing with gasoline/diesel and common internal combustion engines, that familiarity may not extend to alternative fuel vehicles. And the unique propulsion system characteristics of a particular vehicle, such as an alternative fuel vehicle may not be immediately apparent from the vehicle's external appearance.
