Footnotes

The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty. The California Air Resources Board has also determined that the failure to perform this maintenance item will not limit the recall liability prior to the completion of the vehicle useful life. GM, however, urges that all recommended maintenance be recorded.
