Aftertreatment System Indicators Label
Engines and vehicles manufactured after December 31, 2006 and domiciled in the U.S. or Canada are required to meet all EPA regulations effective as of the vehicle build date, and are equipped with an emission aftertreatment system (ATS). Vehicles domiciled outside of the U.S. and Canada may not have aftertreatment equipment, depending upon local statutory emissions guidelines. See .
A warning label on the driver-side visor contains important warning indicators in the instrument cluster that pertain to the ATS. See . see Fig. or see Fig..
It is a violation of U.S. federal law to alter exhaust plumbing, ATS, or other components in any way that would bring the engine/vehicle out of compliance with certification requirements [Ref: 42 U.S.C. S7522(a) (3)]. It is the owner’s responsibility to maintain the vehicle so that it conforms to EPA regulations.

Regulation: Emissions Components |
|
January 1, 2007–December 31, 2009 |
EPA07 (reduce nitrogen oxides (NOx) emissions to 1.1 g/bhp-hr, and reduce particulate matter emissions to 0.01 g/bhp-hr): Aftertreatment device (ATD) containing a diesel particulate filter that traps soot and ash.* |
|
January 1, 2010–December 31, 2012 |
EPA10 (reduce NOx emissions to 0.2 g/bhp-hr): EPA07-type ATD, with additional selective catalyst reduction (SCR) technology that utilizes diesel exhaust fluid (DEF) to convert NOx to nitrogen and water vapor. |
|
From March 5, 2012–December 31, 2015 |
GHG14: Aerodynamic and fuel efficiency components including, but not limited to, tires, cab/sleeper side extenders, chassis fairings, bumper, hood, vehicle speed limiters, and idle reduction timers specifically designed to meet regulatory fuel efficiency and greenhouse gas emissions standards. |
|
From January 1, 2016 |
GHG17: GHG14 components plus OBD16 instrumentation and sensor upgrades, and component technology that meets NHTSA and EPA 2017 fuel efficiency and greenhouse gas emission standards (GHG17) requirements. |
