Simply drive normally for about one week. Keep the gas tank between 3/4 and 1/4 so all the computer diagnostics can run and all the readiness monitors will set. Or Google "OBD II drive cycle". There is a procedure, too lengthy to post here, that will set the readiness monitors in about 45 minutes. HTH. -Jim
