ENGINE OPERATION - Operating Instructions 1 regeneration. This is not a problem with the vehicle; however, it indicates that the driver needs to start a parked DPF regeneration to prevent equipment damage caused by soot build up. If the DPF lamp turns ON and the driver is prompted to through driver notifications, perform a parked DPF Regeneration. system will restart the cycle 10 minutes later with increased rpm until all of the deposits are removed from the DPF. If the vehicle cannot perform an automatic cycle, the driver may be prompted with message to regenerate the DPF with a "Do Not Drive" message. The driver must complete a regeneration before driving.
If the "Do Not Drive" message is ignored and a DPF regeneration is not fully completed before driving, there is a high possibility of equipment damage. Engine Shutdown Prevent engine damage by following these shutdown precautions. NOTE DO NOT shut off the engine immedi- ately. A hot engine stores a great amount of heat and it does not cool down immediately after it is shut off. Always cool the engine down before shutting it off. You will greatly increase its service life. CAUTION If you ignore the warning lamp and do not initiate regeneration at the soon- est, safest possible time, the DPF will become increasingly clogged with soot and can lead to severe engine derate.
Failure to comply may result in equip- ment or property damage. If an engine must idle for an extended period of time, idle the engine at the lowest rpm that maintains the engine coolant at 150°F (70°C), or above. Idle the engine at 1,000 rpm for four minutes. Then low idle for 30 seconds before shutdown. This will allow circulating coolant and lubricating oil to carry heat away from the cylinder head, valves, pistons, cylinder liners, turbocharger, and bearings. This way you can prevent engine damage that may result from uneven cooling. CAUTION Extended engine idling may also increase hydrocarbon deposits and moisture in the DPF.
The engine will increase rpm automatically, regardless if the DPF lamp is on or off, to remove these hydrocarbon deposits and moisture. The engine speed will remain elevated for 20-60 minutes. If necessary, the rpms may be lowered by briefly depressing the throttle, clutch, or brake pedal. If the driver cancels the automatic cycle using the pedals, the DO NOT idle the engine for excessive- ly long periods. Long periods of idling, more than 10 minutes, can cause poor engine performance. Following these guidelines will help reduce engine wear during idling and the frequency of DPF regenerations. 26 Y53-1183-1E1 (04/16/18)
