# enableFan

A Boolean value indicating whether to turn on the cabin fan system.

iOS, iPadOS, Mac Catalyst, tvOS, visionOS, watchOS:

```
@property (nonatomic, copy, readonly, nullable) NSNumber * enableFan;
```

macOS:

```
@property (atomic, copy, readonly, nullable) NSNumber * enableFan;
```

## Discussion

Enabling the fan typically disengages the automated climate control systems and causes the vehicle to enter a manual mode. Check the [`fanSpeedIndex`](/documentation/Intents/INSetClimateSettingsInCarIntent/fanSpeedIndex-4c1rr), [`fanSpeedPercentage`](/documentation/Intents/INSetClimateSettingsInCarIntent/fanSpeedPercentage-ep0u), or [`relativeFanSpeedSetting`](/documentation/Intents/INSetClimateSettingsInCarIntent/relativeFanSpeedSetting) properties to determine whether the user specified a speed for the fan.

This property is `nil` when the user modified a different climate control setting.
