D - Disable

Your machine is equipped with an emission compliant engine, which cleans and filters the engine exhaust. Under normal machine operation and with system in Automatic (AUTO) mode, the system requires minimal operator interaction. Please read the Exhaust Filter Cleaning sections to understand when and where operator interaction may be required.

To avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system:

  • Utilize AUTO exhaust filter cleaning mode.
  • Avoid unnecessary idling.
  • Use proper engine oil. (See Fuels, Lubricants, and Coolants section for recommendations.)
  • Use only ultra low sulfur fuel. (See Fuels, Lubricants, and Coolants section for recommendations.)

Use three position exhaust filter cleaning mode switch (A) to select exhaust filter cleaning modes; Parked (B), AUTO (C), and Disable (D).

IMPORTANT: When vehicle use is not suited for higher temperatures created by exhaust filter cleaning, use the Disable mode (D). Be sure to re-enable Automatic mode (C) as soon as possible to avoid unnecessary soot built up in exhaust filter.

Remember to select Disable mode (D) when temporarily connected to an indoor ducted exhaust system during vehicle diagnostic and repair activities.
