Sequential manual gearbox SMG*The conceptThe sequential manual gearbox SMG is
an automated manual gearbox with
which clutching and shifting is assumed
by an electro-hydraulic system.
The SMG is operated via the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automatic operation
>Ability to choose between two differ-
ent driving programs: Standard,
Sport
>Operating safety through protection
against misshifting
>Automatic upshifts and downshifts in
the drive mode
>Automatic downshifts at minimum
engine rpm
>Kickdown function in the drive mode.
>Acceleration assistant, refer to
page 76.
Selector lever positionsThe current selector lever position is
indicated by a light-emitting diode in
the center console.
R: Reverse
N: Neutral
Position for forward driving with one-
touch functions:
Sequential mode
+: manual upshifts
—: manual downshifts
D: drive mode.
The SMG is ready for operation in igni-
tion key position 2.
The gearbox is automatically
placed in neutral gear if the
driver's door is opened while the engine
is running and the driver does not actu-
ate the pedals, the shift paddles or the
selector lever.
This is accompanied by an acoustic
signal and the flashing gear indicator.
The gear display N appears in the
instrument cluster.
A driving position can only be engaged
when the driver's door is closed.
When the vehicle is unlocked, a buzzer
in the area of the transmission indicates
that the system is ready for operation.<
ShiftlockWhen the car is at a standstill, a safety
function requires you to depress the
brake pedal if you want to move the
selector lever from the neutral
position N to a driving position.Driving precautions
Use enough acceleration to pull
away speedily when moving off on
an uphill gradient. Never try to prevent
the car from rolling back on an uphill
gradient by depressing the accelerator
pedal; always apply the handbrake.
Otherwise you could overheat the SMG
gearbox.<
