Sequential Manual
Transmission with Drivelogic
The concept
The SMG Sequential Manual Transmission
with Drivelogic is an automated manual trans-
mission in which an electrohydraulic system
handles the clutching and gear changes.
The Sequential Manual Transmission is oper-
ated with the selector lever and two shift pad-
dles on the steering wheel.
It offers you the following functions:
>
Optional manual or automatic operation:
Sequential mode or Drive mode
>
Selection option between different driving
programs, Drivelogic, refer to page
>
Upshift display, shift lights, refer to page
>
Automatic downshifting and prevention of
incorrect shifting even in Sequential opera-
tion
>
Automatic double clutching
Selector lever positions
>
R: Reverse gear
>
N: Neutral
>
Β: Drive position:
>
+: manual upshifting
>
–: manual downshifting
>
D/S: switch between Drive mode and
Sequential mode
Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
N Idle
Always select before starting engine.
If the driving situation requires, e.g. when down-
shifting on a slippery road surface, the Sequen-
tial Manual Transmission automatically
clutches and then declutches again, i.e. it is not
necessary to manually shift into idling mode.
The system shifts into N when you open
the driver's door or the hood with the
engine running and do not operate pedals, shift
paddles or the selector lever. To begin driving
after closing the driver's door or the hood, first
shift the selector lever into the N position, and
then shift into drive.
<
S Sequential mode
You can shift up and down using the shift pad-
dles or the selector lever. You do not need to
remove your foot from the accelerator to do so.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D/S.
To switch back into the Sequential mode: shift
using the shift paddles or the selector lever or
press selector lever to the right toward D/S
again.
Starting off is also possible on a level road sur-
face in second gear, e.g. in case of ice.
In the following situations, the Sequential Man-
ual Transmission thinks for you:
>
Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>
When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>
Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.
