On all Volvos equipped with an O2 sensor you'll find a dashboard light that looks like an upside-down 'y'. This is the Greek letter Lamda, which is Volvo's name for their O2 sensor based emissions control system. Usually the Lambda light only comes on during startup, but major problems (faulty sensor, faulty computer, catastrophic engine failure) can trigger the Lamda light. In newer Volvos you'll usually get a "Check Engine" code first, so don't ignore it, because when the Lamda light comes on you need to fix it ASAP!
