  1. Aftertreatment Lamps- Level 1 • DPF Lamp • On solid at Level 1 soot loading • Label says : • “Exhaust filter regeneration required.” • “Drive on highway at highway speeds OR start Parked Regeneration to prevent loss of engine power.”

  2. Aftertreatment Lamps- Level 2 • DPF Lamp • Flashes at Level 2 soot loading • Label says: • “Exhaust filter full” • “Pull vehicle safely off roadway and start Parked Regeneration to prevent loss of engine power.”

  3. Aftertreatment Lamps- Level 3 • Amber Warning Lamp is on • Audible alarm is on • Warn Engine text on LCD • DPF Lamp Flashes • Label says: • “Exhaust filter full. Engine performance LIMITED.” • “Pull vehicle safely off roadway and start Parked Regeneration to prevent engine stopping.”

  4. Aftertreatment Lamps- Level 4 Stop Engine Lamp is on • DPF Lamp is off • If not preceded by level 1, 2, & 3 warnings, it is on for an engine issue other than DPF plugging • Audible alarm is on • Label says: • “A serious engine problem has occurred. Exhaust filter may be overfull. Engine may SHUTDOWN soon.” • “Pull vehicle safely off roadway, turn on flashers, place warning devices STOP ENGINE. Seek service immediately.

Other emission-related faults Malfunction Indicator Lamp (MIL) is on • Will turn on if DPF sensor faults are detected – or for other emission-related faults • Fault codes will be present • Lamp will not flash • May still step through DPF levels with the appropriate warnings • Attempting to perform a stationary regeneration will not change lamp status

  6. HEST Lamp High exhaust system temperature (HEST) Lamp • Turns on if exhaust temps exceed 400˚ C and vehicle speed is less than 5 MPH • Turns off when exhaust is below 370˚ C • High temperatures could be due to passive or active regen. • Label says: • “Exhaust components and exhaust gas are at extremely high temperatures. When stationary, keep away from people and flammable materials, vapors, or structures or STOP ENGINE.

  7. Driver Interface – Parked Regen • Pre-Set Conditions • - Parking Brake Set • Transmission in Neutral • or Park See_Visor For_Info • Desired Response • - Push PARKD REGEN switch • - Driver goes “Hands-Off” • No accelerator pedal input • No brake pedal input • No clutch pedal input • - Engine ECU takes control Decreasing Soot Load

  8. Medium Duty Product Emission Visor Decal
