# CarPlay

## iPhone interactions

**Eliminate app interactions on iPhone when CarPlay is active.**

**Never lock people out of CarPlay because the connected iPhone requires input.**

**Make sure your app works without requiring people to unlock iPhone.**

### Audio

**Let people choose when to start playback.**

**Start playback as soon as audio has sufficiently loaded.**

**Display the Now Playing screen when audio is ready to play.**

**Resume audio playback after an interruption only when it’s appropriate.**

**When necessary, automatically adjust audio levels, but don’t change the overall volume.**

## Layout

**Provide useful, high-value information in a clean layout that’s easy to scan from the driver’s seat.**

**Maintain an overall consistent appearance throughout your app.**

**Ensure that primary content stands out and feels actionable.**

## Color

**In general, prefer a limited color palette that coordinates with your app logo.**

**Avoid using the same color for interactive and noninteractive elements.**

**Test your app’s color scheme under a variety of lighting conditions in an actual car.**

**Ensure your app looks great in both dark and light environments.**

**Choose colors that help you communicate effectively with everyone.**

## Icons and images

**Supply high-resolution images with scale factors of @2x and @3x for all CarPlay artwork in your app.**

**Mirror your iPhone app icon.**

**Don’t use black for your icon’s background.**

## Error handling

**Report errors in CarPlay, not on the connected iPhone.**
