BMW X3 Owners Manual: Steptronic Sport transmission: Launch Control
The concept Launch Control enables optimum acceleration on surfaces with good traction.
Hints
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.
Do not use Launch Control during the break-in, period.
To increase vehicle stability, activate DSC again as soon as possible.
An experienced driver may be able to achieve better acceleration values in DSC OFF mode.
Requirements Launch Control is available when the engine is warmed up, that is, after uninterrupted driving of at least 6 miles/10 km.
