Operating modes
Vehicle is ready for operation, selector position P or N
Electric drive mode (starting with CLC open / driving with controlled CLC)
The gearbox schematic shows the power flow while driving in
electric mode or in 1st gear.
The converter is used for starting. The converter lockup clutch is
open at start-up, in order to utilise the increased torque of the
converter. Operation of the converter lockup clutch is controlled
while driving.
The separation clutch K0 is open while driving in electric mode. The
internal combustion engine is shut o. A prerequisite for driving in
electric mode is that the hybrid battery has sucient charge (refer
to page 9 on SSP 650).
When driving in electric mode, the e-machine or the electric drive
motor V141 delivers a peak power output of 94 kW (refer to
page30).
The other gears are shifted by activating the shift elements as
described in the shift matrix on page 46.

The vehicle is ready for operation. This is indicated to the driver as
soon as "e-tronREADY" is displayed in the dash panel insert (refer
to page 39 of SSP650).
A supply of ATF pressure is ensured. Selector position P orN is
selected.
