Driver Control Switches

Vehicles with manual transmissions allow the driver to turn the engine brake on and off and select a Low, Medium, or High level of braking.

• The "Low" setting on this switch activates braking on two cylinders, yielding about one-third engine braking horsepower.
• The "Medium" setting on this switch activates four cylinders, supplying about two-thirds engine braking horsepower.
• The "High" setting on this switch activates all six cylinders, providing full engine brake horsepower.
