Active Fuel Management™ Vehicles with V8 engines may have Active Fuel Management™. This system allows the engine to operate on either all or half of its cylinders, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will operate in the half cylinder mode, allowing the vehicle to achieve better fuel economy. When greater power demands are required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation. If the vehicle has an Active Fuel Management™ indicator, see DIC Operation and Displays on page 4‑42 for more information on using this display . Automatic Transmission Operation If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information. The vehicle has a Hydra-Matic® 6L80 automatic transmission, and has an electronic shift position indicator within the instrument panel cluster. The electronic shift position indicator displays when the shift lever is moved out of P (Park). There are several different positions for the shift lever. P (Park): This position locks the rear wheels. It is the best position to use when you start the engine because the vehicle cannot move easily. 3-32
