Exhaust filter is restricted when:

• Warning indicator (A) is illuminated.
• Exhaust filter indicator (B) is illuminated.
• Engine power is reduced.

The system requires a parked cleaning. Five consecutive tones warn operator that a parked cleaning is required.

1. CAUTION: Comply with Clean Exhaust Filter Safely in Section 05.

   IMPORTANT: Park the vehicle in a suitable space and lower any implements all the way to the ground.

   Use NO other vehicle functions while exhaust filter cleaning is taking place with the vehicle parked. Excluded are functions that are required for an emergency shutdown of the vehicle.

   Do not start exhaust filter cleaning if the fuel gauge has been showing a low fuel level for a long time.

   Stop tractor, place transmission in park position, disengage PTO, and set engine idle to low 900 RPM.

2. Press and hold exhaust filter cleaning switch in parked cleaning position (C) for 3 seconds then release.

   IMPORTANT: If necessary, it is possible to cancel a parked exhaust filter cleaning process by manually advancing throttle, engaging transmission, or stopping engine.

3. The engine speed increases to 1800 RPM.

4. During the parked cleaning process, the engine emissions temperature indicator (D) illuminates.

5. NOTE: The parked exhaust filter cleaning process takes 30—45 minutes to complete.

   Engine hours indicator (E) turns off and a percent numeric value of parked cleaning process is shown in vehicle information display (F). First; a preparation stage value increases from 1 to 100. During preparation stage, the exhaust filter cleaning system increases engine speed to increase exhaust temperature. Second; an exhaust filter cleaning value increases from 1 to 100. During cleaning stage, sulfur or urea deposits are cleaned from exhaust filter.

6. When the parked cleaning process is complete exhaust filter indicator and warning indicator turns off. Engine emissions temperature indicator remains on for 30 seconds and engine speed returns to 900 RPM.

7. After engine emissions temperature indicator turns off and engine hours indicator turns on, continue vehicle operations as normal

   NOTE: The system defaults to Automatic (AUTO) exhaust filter cleaning mode.

   If not returning vehicle to operation, allow engine time to return to normal operating temperature before stopping engine.

IMPORTANT: If operator disregards indicators and continues to operate vehicle without allowing a parked cleaning, engine performance is reduced. Have a John Deere dealer perform a service exhaust cleaning procedure.
