FEDERAL EMISSION CONTROL WARRANTY

2021_C708UN20K_Edition1

Each Owner is required to comply with the Written Maintenance Instructions and a 
claim under this warranty may be denied on the basis of noncompliance by the Owner 
with such instructions. 

If and when it is considered that the vehicle’s nonconformity 

with the applicable emission standards has resulted from the Owner’s 
noncompliance with those Written Maintenance Instructions which the 
manufacturer considers necessary for the vehicle to meet the standards, the Owner 
may be required to submit evidence of such compliance. Receipts and other 
documents covering the performance of Scheduled Maintenance and proper use 
in  accordance with the Written Maintenance Instructions, including but not limited 
to the validated Scheduled Maintenance Record in this booklet, should, therefore, 
be retained by the Owner and should be transferred to each subsequent Owner of 
the Mazda Vehicle.

Compliance with Written Maintenance Instructions

The Mazda Vehicle is designed, built and tested using Mazda Parts so that the Mazda 
Vehicle is able to perform in conformity with EPA regulations as provided by this 
warranty. Accordingly, it is recommended that any replacement parts used for 
maintenance, repair or replacement of the Mazda Vehicle be Mazda Parts, or parts 
equivalent to those with which the Mazda Vehicle or its engine was originally equipped.

Use of Mazda Parts

Owners may elect to use parts other than Mazda Parts in the performance of any 
maintenance or repairs and such use in itself will not invalidate this warranty. However, 
use of parts other than Mazda, may cause Mazda to deny an emission performance 
warranty claim on the basis of uncertified replacement parts used in the maintenance or 
repair of a Mazda Vehicle if the uncertified replacement parts are either defective in 
material or workmanship or not equivalent, from an emission standpoint, to Mazda 
Parts.

Use of Non-Mazda Parts

Mazda’s obligation to remedy nonconformities under this warranty shall be performed 
by a Mazda Dealer, which shall make all adjustments, repairs or replacements 
necessary to assure that the Mazda Vehicle complies with applicable emission 
standards of the EPA and that the Mazda Vehicle will continue to comply during the 
remainder of the term of this warranty (if proper maintenance and operation are 
continued).

Repair or Replacement by Mazda Dealer
