High-grip road surface
Important: Launch control can lead to increased wear of components.
Do not accelerate using launch control during the running-in phase of a new car. Frequent use of
launch control leads to increased component wear.
Slip detection
A disproportionate amount of wheel slip may occur when engaging the clutch or during a load change (e.g. on
wet or icy road surfaces). The clutch is disengaged to stabilise the vehicle.
The procedure is executed as follows:
•
The clutch is opened after wheel slip is detected between the wheels on the rear axle and front axle on the
same side. This counteracts the vehicle swerving out.
•
Afterwards, the clutch engages softly in response to further wheel slip.
•
The clutch opens and closes as required until no more wheel slip is detected when the clutch is closed.
Pulling away on a slope
Special software is loaded into the sequential M transmission to ease pulling away on a slope (on an uphill
slope, the vehicle could roll back when the brakes are released).
The brakes intervene automatically to ease pulling away on a slope. The function may be used in both manual
and automatic modes (when driving forwards and reversing).
This is initiated merely by pressing down the brake pedal when the vehicle is stationary. After the brake has
been released, it is possible to drive off after approximately 0.8 seconds without rolling away out of control.
During this time period, after the brake has been released the engine speed is increased to a level to match the
slope. The clutch is moved to the clutch slipping point, which briefly prevents the vehicle from rolling back.
Vehicle standstill
The SMG control unit detects vehicle standstill from the accelerator pedal position, the wheel speeds and the
engine speed. The clutch disengages. The 1st gear is selected (in manual and automatic modes).
If the driver's door or bonnet are opened when the engine is running, an acoustic signal draws attention to the
position of the transmission. Reason: A drive position is still engaged and the transmission is not in position "N").
At the same time, the "N" symbol flashes in the LCD display in the instrument cluster.
If despite this, neither the pedals, the gearshift paddles nor the gear lever are moved, the gear will automatically
be cancelled after approx. 2 seconds.
Gear lever position "Neutral" and ignition OFF
When the gear lever is in "Neutral" position and the ignition is switched off, the "N" symbol flashes in the LCD
display of the instrument cluster. In addition, the multi-audio system controller (M-ASK) will emit an acoustic
warning. Reason: The vehicle may roll away.)
Gear lever lock (shift-lock)
The gear lever lock prevents an unintentional gearshift.
When the vehicle is stationary, it is only possible to select a drive position when the brake is still applied and
approximately 1.5 seconds after the "Neutral" gear lever position has been selected (for safety reasons).
The gear lever is locked in the "Neutral" position by an electromagnet (electromagnet locks in a current-free
state). The electromagnet is actuated by the SMG control unit. The gear lever lock is engaged when selector
lever position "N" is detected and the ignition (terminal 15) is ON.
