FEDERAL EMISSION CONTROL WARRANTY
2021_C708UN20K_Edition1
1. Introduction
The Federal Clean Air Act requires vehicle manufacturers to provide two emissions 
related warranties:
• The Federal Emissions Performance Warranty, which covers repairs to certain parts of
each vehicle’s emission control system if certain conditions are met (see Section 5, for 
those conditions).
• The Federal Emissions Defect Warranty, which covers certain parts of each vehicle’s
emissions control systems against defects in materials and workmanship, and
These two emission warranties apply to all Mazda Vehicles (including those registered 
in states requiring California-certified vehicles). They are given in lieu of all other 
express or implied warranties (except those set forth separately in this booklet) on the 
part of Mazda, Mazda Importer/Distributor or the Mazda Dealer selling this Mazda 
Vehicle. No dealer, or any agent or employee thereof, is authorized to extend or 
expand these warranties.
