Engine Brake Switches

57x 04.04.002

When vehicle braking is required on good road conditions, the engine brake may be used in conjunction with the service brakes. There is no time limit for operation of the engine brake. However, an engine brake does not provide the precise control of, and is not a substitute for, service brakes.

The engine brake control is located on the right-hand steering-column-mounted lever. At the top position, the engine brake is off, and at the three lower positions, the brake is on and the intensity (low, medium, high) increases with each step down. See Fig..

  1. Off

  2. Low

Note:  The cruise control system and safety systems may activate the engine brake regardless of the lever position.

See Brake System Operation for detailed information about engine brake operation.
