# INSetDefrosterSettingsInCarIntent

A request to change the defroster settings in a CarPlay-enabled vehicle.

```
class INSetDefrosterSettingsInCarIntent
```

## Overview

Automotive venders can add support for this intent to an Intents extension that they ship with their automotive apps. When the user asks Siri to change the defroster settings for a vehicle, SiriKit creates an [`INSetDefrosterSettingsInCarIntent`](/documentation/Intents/INSetDefrosterSettingsInCarIntent) object and delivers it to the app’s Intents extension. You use the intent to identify which defroster the user wants to enable or disable and to communicate the changes directly to your vehicle’s systems.

The object that handles this intent must adopt the [`INSetDefrosterSettingsInCarIntentHandling`](/documentation/Intents/INSetDefrosterSettingsInCarIntentHandling) protocol. Use this intent object to resolve the defroster details and to create an [`INSetDefrosterSettingsInCarIntentResponse`](/documentation/Intents/INSetDefrosterSettingsInCarIntentResponse) object indicating whether you were able to make the change successfully.

### Additional Intent Attributes

When managing CarPlay features, users don’t need to include the name of the app in the phrases that they speak. Siri knows automatically when CarPlay is active and routes CarPlay-related intents to the app of the corresponding automotive vendor.
