Sequential manual gearbox

SMG*

The concept

The sequential manual gearbox SMG is an
automated manual gearbox with which clutch-
ing and shifting is assumed by an electro-
hydraulic system.
The SMG is operated via two shift paddles on
the steering wheel and the selector lever in the
center console.
It offers the following functions:

Optionally manual or automatic operation:
sequential mode or drive mode

Ability to choose between two different
driving programs: standard or Sport, refer to
page

Protection against misshifting, and auto-
matic downshifting at minimum engine rpm
even in sequential mode

Kickdown function in the drive mode

Acceleration assistant, refer to page

The SMG is ready for operation when the igni-
tion key is in position 2.

Selector lever positions

You can see the current selector lever position
in the center console.

R: Reverse

N: Neutral

One-touch functions for the sequential
mode
+: manual upshifting
–: manual downshifting

D: Drive mode.

N is automatically selected if the driver's
door is opened while the engine is run-

ning and the driver does not actuate the pedals,
the shift paddles or the selector lever.
This is accompanied by an acoustic signal and a
flashing N in the instrument cluster.

ing out of N, depress the footbrake, as other-
wise the desired gear shift is not executed.

Sequential mode

Each time the engine is started, the sequential
mode is activated as soon as you move the
selector lever towards the right while depress-
ing the brake pedal.
The gear is changed via the shift paddles or the
selector lever.
It is also possible to drive off in second gear, e.g.
on slippery roads.

D Drive mode

In the drive mode all forward gears are shifted
automatically.
To switch from sequential to drive mode: tap
the selector lever to the right toward D.
