Note:  See Chapter 12 for detailed information about the operation of the regeneration (regen) switches and the aftertreatment system (ATS).

Important: Depending upon local jurisdictional emissions guidelines, vehicles that are domiciled outside of the U.S. and Canada may not have engines and/or emissions aftertreatment systems that are compliant with EPA07, EPA10, GHG14, or GHG17 regulations.

The regen request switch, located on the dash, is used to initiate a parked regen. See Fig.. To access the regen request switch, lift the guard and press the yellow button.

Some vehicles may be equipped with a regen inhibit switch. See Fig.. To stop a regen in progress or prevent the start of a regen, press the lower half of the switch. Regen will be delayed until the switch is no longer active.
