[Dagger] 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 or limit recall liability prior to the completion of the vehicle's useful life. GM, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.
