Launch Control

Principle

Launch Control enables optimum acceleration on roads with good traction under dry surrounding conditions.

General information

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.

Additional information: Breaking-in period.

Functional requirement

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.

Start with launch control

1. Turn on drive readiness.

2. Press the button.

TRACTION is displayed in the instrument cluster and the indicator light for DSC OFF lights up.

3. Engage selector lever position S.

4. With the 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.

6. The starting engine speed adjusts. Wait briefly until the engine speed is constant.

Keep the accelerator pedal in this position.

7. Release the brake within 3 seconds after the destination flag illuminates.

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, the transmission must cool down for approx. 5 minutes before Launch Control can be used again.

Launch Control adjusts to the surrounding conditions, when used again.

After using Launch Control

To increase driving stability, activate DSC Dynamic Stability Control again as soon as possible.

System limits

An experienced driver may be able to achieve better acceleration values in DSC OFF mode.
