Engine Brake Operation
Notice: Do not allow the engine to exceed its governed speed, or serious engine damage could result.
Note: Depending on the brake type, the engine brake may be disabled when engine temperature falls below a set level.
The engine brake control is located on the right-hand steering column lever. At the top position, the engine brake is off, and at the three lower positions, the engine brake is on and the intensity (low, medium, high) increases with each step down. See Fig..
Note: The cruise control system and safety systems may activate the engine brake regardless of the lever position.
Note: On vehicles equipped with a Detroit automated transmission, setting the engine brake with the cruise control set activates Deceleration Mode. Setting the cruise control while the engine brake is on activates Descent Control Mode. For information on these modes, see "Descent Control Mode" inChapter 14 .
