Sequential M gearbox with Drivelogic*
The concept
>Operating safety through protection
against misshifting.
The sequential M gearbox with
Drivelogic is an automated manual
gearbox with which clutching and shift-
ing is assumed by an electro-hydraulic
system.
Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
The SMG Drivelogic is operated via two
shift paddles on the steering wheel and
the selector lever in the center console.
It offers the following functions:
>
Sequential and automated shifting
mode
Selector lever positions
R: Reverse position
>
Ability to choose between different
driving programs – Drivelogic
Gradient assistance, refer to page 73
Upshift display and shift lights, refer
to page 74
RPM matching on downshifts
Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration
N: Neutral position

Forward position with one-touch mode:

>
S: sequential mode
D: automated mode
+: upshifting in sequential mode
–: downshifting in sequential mode.

The SMG Drivelogic is ready for opera-
tion from ignition key position two or
higher.
For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. two seconds after
engaging position N with the footbrake
depressed – shift-lock function.

Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces
