Spoiler settings
It is possible to extend/retract the spoiler using the buttons on the inside of the driver's door. The spoiler only has two positions: fully extended or fully retracted.
Extending the spoiler

The car needs to be in at least ignition position II.
Press the button to extend.
The indicator lamp shines with a constant glow when the spoiler is fully extended.
Retracting the spoiler

The car needs to be in at least ignition position II.
Press the button to retract.
The indicator lamp is extinguished when the spoiler is retracted.
Warning
When retracting the spoiler at low vehicle speeds or when stationary, pay attention to the risk of crushing.
