To avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system;

• Utilize AUTO Exhaust Filter Cleaning mode
• Avoid unnecessary idling
• Use proper engine oil. See Fuels and Lubricants section for recommendations.
• Use only ultra low sulfur fuel. See Fuels and Lubricants section for recommendations.

Touch or press confirm switch when Engine Information Icon is highlighted.

There are two exhaust filter system modes:

• Auto (A)
• Disable (B)

IMPORTANT: Disable mode should ONLY be used when temporarily connected to an indoor exhaust system for diagnostic and repair activities.

NOTE: Parked exhaust filter cleaning icon (C) may be active or inactive (grayed out) depending on exhaust filter restriction level. See Parked Exhaust Filter Cleaning in this section.

System defaults to AUTO mode when parked exhaust filter cleaning is complete or key switch is cycled. Always verify that AUTO mode is selected, unless in conditions where it may be unsafe. See When to Disable Exhaust Cleaning System in this section.
