Launch Control enables optimum acceleration on roads with good traction under dry surrounding conditions.
The use of Launch Control causes premature component wear since this function represents a very heavy load for the vehicle.
• Do not use Launch Control during the break-in.
• Do not steer the steering wheel when driving off with Launch Control.
Functional requirements: Launch Control is available when the engine is at operating temperature. The engine is at operating temperature after an uninterrupted trip of at least 6 miles/10 km.
Perform the following to use launch control with manual transmission:
1. Turn on drive-ready state.
2. Activate M Dynamic Mode.
M Dynamic Mode (MDM).
3. Step on the clutch pedal.
4. Engage first gear.
5. Press the accelerator pedal all the way down.
A destination flag is displayed in the instrument cluster.
Preparing Launch Control. An appropriate Check Control message is displayed.
Keep the accelerator pedal in this position.
6. The starting engine speed adjusts. With sufficiently high starting torque, the Launch Control is active.
An appropriate Check Control message is displayed.
Disengage the clutch quickly within approx. 6 seconds. The vehicle accelerates.
7. Observe the Shift lights and upshift on time.
Perform the following to use launch control with M Steptronic Sport transmission
1. Turn on drive-ready state.
2. Deactivate the Dynamic Stability Control.
Dynamic Stability Control.
3. Without xDrive: select sequential mode with gear 2 and Drivelogic program S3.
With xDrive: select sequential mode with gear 1 and Drivelogic program S3.
4. With your left foot, forcefully press down on the brake.
5. Press and hold down the accelerator pedal beyond the resistance point at the full throttle position, kickdown.
A destination flag is displayed in the instrument cluster.
Preparing Launch Control. An appropriate Check Control message is displayed.
Keep the accelerator pedal in this position.
6. The starting engine speed adjusts. With sufficiently high starting torque, the Launch Control is active.
An appropriate Check Control message is displayed.
Now release the brake. The vehicle accelerates.
Upshifting occurs automatically as long as the destination flag is displayed and the accelerator pedal is not released.
Repeated use during a trip: After Launch Control has been used, it is necessary to drive a certain distance before Launch Control can be used again. Launch Control adjusts to the surrounding conditions, when used again.
After using Launch Control: To support driving stability, reactivate Dynamic Stability Control as soon as possible.
System limits:
Manual transmission: if drive-off is delayed, the Launch Control is automatically terminated to protect the engine.
• The best acceleration figures are reached with sport tires at operating temperature.
• An experienced driver may be able to achieve better acceleration values in DSC OFF mode.
