Notes:  
Tests Covered: Federal Test Procedure (FTP), cold carbon monoxide, highway, and idle
Model Year: 2004+

a  In lieu of intermediate useful life standards (50,000 miles) or to gain additional nitrogen oxides credit, manufacturers may optionally certify to the Tier 2 exhaust emission standards with a useful life of 150,000 miles.

b  Bins 9-11 expire in 2006 for light-duty vehicles and light light-duty trucks and 2008 for heavy light-duty trucks and medium-duty passenger vehicles.

c  Pollutants with two numbers have a separate certification standard (1st number) and in-use standard (2nd number).
