The 6.7L Power Stroke® Turbo Diesel engine incorporates a driver-activated engine exhaust brake. It restricts the turbocharger’s exhaust flow to generate back pressure and slow the vehicle, providing a reduced need for friction brakes while traveling downhill, regardless of vehicle load or road grade. Also, because the engine brake helps minimize having to apply pedal pressure, brake fade and lining wear are reduced. Three settings are available: On, Off and Auto. The Auto setting modulates engine braking as needed to help maintain the speed you want based on accelerator and brake pedal use.
