Clean Diesel Particulate Filter (DPF)

1. When exhaust filter and warning light indicators are illuminated, ensure that exhaust filter cleaning is set to “Auto”.
2. Operate machine above 1200 rpm to allow an automatic exhaust filter cleaning to occur.
3. If indicators remain illuminated after an automatic cleaning has occurred, additional cleaning is required. Perform parked exhaust filter cleaning (if system allows). See “ Air, Fuel, Coolant, and Exhaust Operation” section for procedure.
4. If a parked exhaust filter cleaning has been performed and exhaust filter and warning light indicators are still illuminated, contact your John Deere dealer.
