German automaker Volkswagen AG admits that it rigged U.S. emissions tests so it would appear that its diesel-powered cars were emitting fewer nitrogen oxides, which can contribute to ozone buildup and respiratory illness. Here are some questions and answers about the ongoing crisis.

Q. Which vehicles does this affect?

A. Volkswagen installed software in roughly 482,000 diesel passenger cars sold in the U.S. since 2008, according to the U.S. Environmental Protection Agency. The software turned on the cars’ full emissions control systems when the cars were being tested by the government, and then turned off those systems during normal driving. The Jetta, Beetle, Audi A3 and Golf from the 2009-2015 model years are affected, as well as the Passat from the 2014-2015 model years. Volkswagen has halted the sale of 2015 models and is prohibited from selling 2016 models until they are fixed.

Q. What does Volkswagen say?

A. The EPA Volkswagen Group CEO Martin Winterkorn issued a statement Sunday saying that the company will fully cooperate with government investigations and has ordered an internal probe. Winterkorn said, “I personally am deeply sorry that we have broken the trust of our customers and the public.”
