90 GETTING TO KNOW YOUR INSTRUMENT PANEL
By simply driving your vehicle at highway speeds for as little as 45 minutes, you can remedy the condition in the particulate filter system and allow your Cummins diesel engine and exhaust after-treatment system to remove the trapped PM and restore the system to normal operating condition. Exhaust System — Regeneration In Process Exhaust Filter XX% Full — Indicates that the DPF is self-cleaning. Maintain your current driving condition until regeneration is completed. Exhaust System — Regeneration Completed — This message indicates that the DPF self-cleaning is completed. If this message is displayed, you will hear one chime to assist in alerting you of this condition. Exhaust Service Required — See Dealer Now — This message indicates regeneration has been disabled due to a system malfunction. At this point the engine Powertrain Control Module (PCM) will register a fault code, the instrument panel will display a MIL light. Exhaust Filter Full — Power Reduced See Dealer — This message indicates the PCM has derated the engine to limit the likelihood of permanent damage to the after-treatment system. If this condition is not corrected and a dealer service is not performed, extensive exhaust after-treat - ment damage can occur. To correct this condi - tion it will be necessary to have your vehicle serviced by an authorized dealer. NOTE: Failing to follow the oil change indicator, changing your oil and resetting the oil change indicator by 0 miles remaining will prevent the diesel exhaust filter from performing it's cleaning routine. This will shortly result in a Malfunction Indicator Light (MIL) and reduced engine power. Only an authorized dealer will be able to correct this condition. Cold Ambient Derate Mode Messages The vehicle will display messages when a derate (engine power reduction) is activated to protect the engine during start up in cold ambient temperatures. Engine Power Reduced During Warm up — This message will display during start up when the ambient temperature is between 10°F (-12°C) and -10°F (-23°C). Engine Power Reduced Up To 30 Sec (Seconds) During Warm up — This message will display during start up when the ambient temperature is between -10°F (-23°C) and -25°F (-32°C). Engine Power Reduced Up To 2 Min (Minutes) During Warm up — This message will display during start up when the ambient temperature is -25°F (-32°C) and below. up protection feature that may limit engine performance after cold starting at low ambient temperatures. The length of time engine speed is limited is dependent upon engine coolant temperature. Engine speed may be briefly limited to 1,000 RPM after starting with coolant temperature below freezing conditions, and may be limited to 1,000 RPM for up to approxi - mately two minutes under more severe cold conditions. Coolant Low — This telltale will turn on to indi - cate the vehicle coolant level is low. Refer to “Dealer Service” in “Servicing And Mainte - nance” for more information. CAUTION! See an authorized dealer, as damage to the exhaust system could occur soon with continued operation. CAUTION!
