Enable Siri™ voice recognition:
Method 1: Press and hold down the "Push To Talk" button located on the steering wheel.
Method 2: Press and hold down the home button located in the bottom left-hand corner of your Apple CarPlay™ screen.
You can then ask several questions and control certain applications vocally, such as making a call, playing music, sending and replying to text messages, using Maps and obtaining routes, creating reminders, etc.
Example: "Call 'contact name'", "Send a message to 'contact name'", "Create a route for 'address'", etc.
Worth noting: Phone calls work through the car's audio system using R-LINK 2. However, voice recognition may not go through the audio system when connecting to Apple CarPlay™. The smartphone may be the source of the problem. If this is the case, please contact user support for the manufacturer of your smartphone.
