# setAccessoryImage(_:)

Updates the list item’s accessory image.

```
func setAccessoryImage(_ accessoryImage: UIImage?)
```

## Parameters

`accessoryImage`

The image to display in the item’s trailing region.

## Discussion

Provide an image that is display-ready. If necessary, provide light and dark variants using an asset catalog, or use an instance of <doc://com.apple.documentation/documentation/UIKit/UIImageAsset> and register an image for each interface style. To properly size your image, use the display scale of the vehicle’s primary screen, which you access from your interface controller’s [`carTraitCollection`](/documentation/CarPlay/CPInterfaceController/carTraitCollection) property. At runtime, use [`maximumImageSize`](/documentation/CarPlay/CPListItem/maximumImageSize) to determine the maximum size for a list item’s accessory image.

CarPlay doesn’t support animated images. If you provide an animated image, CarPlay uses only the first image in the animation sequence.

CarPlay sets the `accessoryType` property’s value to [`CPListItemAccessoryType.none`](/documentation/CarPlay/CPListItemAccessoryType/none) when you call this method.
