Aftertreatment System Indicators Label

Model year 2007 and later diesel engines in vehicles domiciled in the U.S. or Canada are required to meet all EPA exhaust gas emission regulations effective as per the applicable emission model year, 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 Table 1.1 and Table 1.2 at the end of this chapter for additional information on what EPA and GHG regulations apply to different model years.

See Fig. for information on the driver's visor warning label for important warning indicators in the instrument cluster that pertain to the ATS.

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.
