Active Fuel Management™
Your vehicle’s V8 engine may have Active Fuel Management™. This system allows the engine to operate on either all or half of its cylinders, depending on your 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 your 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.
