Use Siri in your car
With CarPlay or Siri Eyes Free, you can keep focused on the road by using Siri to make calls, send text messages, play music that’s on your iPhone, get directions, and use other iPhone features.
CarPlay (available in select cars) takes the things you want to do with your iPhone while driving and puts them on your car’s built-in display. CarPlay uses Siri, so you can ask Siri for what you want. See Control CarPlay with Siri.
With Siri Eyes Free (available in select cars), use your voice to control features of your iPhone without looking at or touching iPhone. To connect iPhone to your car, use Bluetooth (refer to the user guide that came with your car if you need to). To summon Siri, press and hold the voice command button on your steering wheel until you hear the Siri tone, then make a request.
