General
The rear spoiler is used to adjust the contact pressure of the vehicle in various vehicle speed ranges. The rear spoiler is moved via the rear spoiler motor. It extends and retracts to different positions depending on the drive program selected and the speed being traveled. It influences handling characteristics in the event of rapid cornering and supports the driver when braking with the airbrake function.
In addition to the manually adjustable upper wing section, the rear wing has a second wing section mounted in a lower position that generates additional downforce.
Function requirements
- Terminal 15 ON
- Trunk lid closed
Function
Function sequence for manual adjustment
The rear spoiler can be extended and retracted using the control elements on the steering wheel or via the multimedia system. A brief actuation of the button is sufficient for extending the rear spoiler.
Pressing and holding the button down results in an extension or retraction. If the switch is released before the upper or lower end position has been reached, the rear spoiler reverses.
Visual feedback signal
Visual feedback is provided via the control elements on the steering wheel and via the instrument cluster or driver's display. The following messages can be displayed here:
- Blue: Rear spoiler retracted
- Red: Rear spoiler extended in different positions
- Yellow: Rear spoiler extending or retracting
- In the event of a defective rear spoiler or defective rear spoiler control: "Rear spoiler control nonfunctional"
- In the event of an inadmissible adjustment request: "Rear spoiler nonfunctional limit 200 km/h"
In the event of a fault message, an alarm signal also sounds.
