# INSetDefrosterSettingsInCarIntentHandling

The handler interface for changing a vehicle’s defroster settings.

## Declaration

```swift
protocol INSetDefrosterSettingsInCarIntentHandling : NSObjectProtocol
```

## Overview

Overview Automotive vendors can support the INSetDefrosterSettingsInCarIntentHandling protocol in an Intents extension that they ship with their automotive apps. Use the methods of this protocol to resolve, confirm, and handle requests to change the vehicle’s defroster settings. Your extension should be able to communicate with the vehicle and make the necessary climate control changes. Siri delivers an INSetDefrosterSettingsInCarIntent object to your handler when the user asks to change the defroster change. The intent object contains information that you use to determine the new defroster settings and to make the change.
