Engine Emission Control

Operator Commanded Regeneration with Automatic Regeneration Control (If Equipped) If your vehicle is operated with significant stationary operation, low speed drive cycles less than 25 mph (40 km/h), short drive cycles, drive time less than 15minutes or the vehicle does not fully warm up, passive and active regeneration may not sufficiently clean the diesel particulate filter system. You can switch off automatic regeneration until better driving conditions are available, for example steady high speed driving. You can then switch automatic regeneration back on to clean the diesel particulate filter. Switching Automatic Regeneration Control On and Off To switch operator commanded regeneration on and off, use the information display control on the steering wheel. See InformationDisplayControl (page 85). Scroll to the exhaust cleaning message, a check in the box indicates the feature is enabled, and unchecked indicates the feature is disabled. How to Interrupt or Cancel Operator Commanded Regeneration If you need to cancel the operator commanded regeneration, pressing the brake, accelerator or switching the engine off stops the procedure. Depending on the amount of time you allowed the operator commanded regeneration to operate, soot may not have had sufficient time to be fully eliminated, but the exhaust system and exhaust gas may still be hot. If you shut your vehicle off during operator commanded regeneration, youmay notice turbo flutter. This is a normal consequence caused by shutting off a diesel engine duringboostedoperationand is considered normal.

If the diesel particulate filter is near or at saturation, a message requesting permission to initiate filter cleaning appears in the information display. See InformationMessages (page 123). Answer yes to this prompt and then follow the next prompts regarding exhaust position required to initiate operator commanded regeneration. Be sure to understand each prompt. If you are not sure what is being asked by each prompt, contact an authorized dealer. The display confirms the operation has started and when it has finished. You can also drive to clean the filter. and amessage appears in the information display. You cannot initiate filter cleaning. You must have your vehicle checked as soon as possible. Once operator commanded regeneration starts, engine speed increases to approximately 2000 rpm and the cooling fan speed increases. You will hear a change in audible sound due to engine speed and cooling fan speed increases. It is not necessary to open the hood on the engine compartment. Once operator commanded regeneration completes, the engine speed returns to normal idling. The exhaust system remains very hot for several minutes even after regeneration is complete. Do not reposition the vehicle over materials that could burn until the exhaust system has had sufficient time to cool. Depending on the amount of soot collected by the diesel particulate filter, ambient temperature and altitude, operator commanded regeneration lasts approximately 30 minutes. When the system is at the point of oversaturation, the service enginewarning lamp illuminates
