Found the launch control information from
the Owner's Manual:
Launch Control
The concept
Launch Control enables optimum acceleration on surfaces with good traction.
Component wear
Do not use Launch Control too often; otherwise, this may result in premature wear of components due to the high stress placed on the vehicle.
Activate Launch Control
Launch Control is available when the engine is warmed up, that is, after uninterrupted driving of at least 6 miles/10 km.
1. Deactivate Dynamic Stability Control.
2. Select Sequential mode with driving program 3.
3. With the engine running, apply the brake with the left foot.
4. Fully depress the accelerator pedal.
The starting engine speed adjusts.
A flag symbol appears in the instrument cluster.
5. If necessary, change the starting engine speed by 500 rpm via cruise control.
6. Release the brake, the vehicle accelerates. Continue to depress the accelerator pedal.
Upshifting occurs automatically as long as the accelerator pedal is fully depressed.
Hints
Launch Control is available only after a certain distance has been driven.
Did not use Launch Control during the break-in period.
To maintain driving stability, always activate DSC if possible.
