Emissions Labels
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. and see Table. 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 it conforms to EPA regulations.
Vehicle Emission Control Information Label
Model year 2013 and later vehicles meet requirements as specified by GHG14, GHG17 and GHG21 regulations, respectively. These vehicles are equipped with components that increase fuel efficiency and reduce greenhouse gas (GHG) emissions. Components may include, but are not limited to, low-rolling resistance tires; aerodynamic devices such as hood, cab side extenders, and fuel tank fairings; vehicle speed limiters; and idle shutdown timers.
A Vehicle Emission Control Information label (see Fig.) is located on the driver-side door (see Fig.). It is the owner's responsibility to maintain the vehicle so it conforms to EPA and NHTSA regulations.

Certified Clean Idle Label
The California Air Resources Board (CARB) requires model year 2008 and newer heavy-duty diesel engines to meet CARB’s Heavy-Duty Diesel Engine Idling Requirement in order to limit idling emissions of particulate matter and NOx.
Certified vehicles are equipped with a label placed near the external bottom edge of the driver-side door. See Fig. for an example of the label.

EPA Noise Emission Control Label
A vehicle noise emission control label ( See Fig.) is located on the driver-side B-pillar as shown in Fig.. It is the owner's responsibility to maintain the vehicle so it conforms to EPA noise regulations.

Fig. 5, Vehicle Noise Emission Control Label (Incomplete Vehicle)
Important: Certain Western Star incomplete vehicles may be produced with incomplete noise control hardware. Such vehicles will have an incomplete vehicle noise emission control information label. See Fig.. For such vehicles, it is the final-stage manufacturer's responsibility to complete the vehicle in conformity to U.S. EPA regulations (40 CFR Part 205) and label it for compliance.
