Adjust Siri Voice Volume LexusUpdated a day ago

Before following these steps, read the Configuring Audio article to make sure you have your audio setup properly. This is an essential step. 

Below is a complete overview view of the steps outlined to adjust Siri's volume (or the volume used for navigation voice). 

1. Make sure your phone is running iOS 26. Earlier iOS versions sometimes do not allow you to independently adjust voice volume. 

2. From CarPlay, tap the Hamilton icon to go to the Hamilton underlying operating system. 

3. Tap Settings > Audio > Volume 

4. Adjust the volume for "Voice." We recommend maxing it out if you want Siri to be loud. 

5. Test your car and enjoy. 

6. If you desire Siri to be even louder, keep "Voice" on the highest setting and adjust the other settings lower. This will cause you to raise the volume of the entire system, as you will use a higher volume setting when listening to music. This will cause Siri to be relatively even louder.
