Chevrolet Silverado: Starting and Operating / Active Fuel Management

Chevrolet Silverado 2019-2025 Owners Manual / Driving and Operating / Starting and Operating / Active Fuel Management

If equipped, Active Fuel Management allows the gasoline engine to operate on either all of its cylinders, or a reduced number of cylinders, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will enable reduced cylinder operation, allowing the vehicle to achieve better fuel economy. When greater power is required, such as  accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation.

Dynamic Fuel Management

If equipped, Dynamic Fuel Management calculates the number of cylinders needed to maximize fuel economy and meet the driving demands. Dynamic Fuel Management allows the engine to operate in multiple possible configurations ranging from 1-cylinder up to the full 8-cylinder operation.
