Sequential M gearbox SMG II*

Under normal operating conditions, fuel
The concept
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
The sequential M gearbox SMG II is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG II 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
>Ability to choose between different
driving programs, Drivelogic
>Gradient assistance, refer to page 74
>Upshift display and shift lights, refer
to page 75
Selector lever position
R: Reverse position
0: Position 0 (Neutral)
Forward position with one-touch mode:
>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
>Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces
>S: sequential mode
>A: automated mode
>+: upshifting in sequential mode
>–: downshifting in sequential mode.
The SMG II is ready for operation 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. 2 seconds after
engaging position 0 with the footbrake
depressed – Shiftlock function.
>Operating safety through protection
against misshifting.
72 Sequential M gearbox SMG II*
You do not need to reduce the throttle
for shifting.
R – Reverse position
Only engage with the vehicle stopped
or at low speed, e.g. for rocking free in
deep snow.
An intermittent signal tone indi-
cates that the reverse position has
been engaged.<
0 – Position 0 (Neutral)
Always engage before starting the
engine.
Display in instrument cluster
If the driving situation requires, e.g.
when downshifting on slippery roads,
the SMG II automatically disengages
and reengages the clutch, i.e. it is not
necessary to manually engage
position 0.
The selector lever position, currently
engaged gear and selected driving pro-
gram are displayed in the instrument
cluster.

sponds to the number of illuminated
fields, refer to page 74
S – Sequential mode
In the sequential mode all forward
gears are to be shifted by the driver.
3 Tapping the selector lever to the right
switches over into the displayed shift
mode

Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
A – Automated mode
Each time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward +
>To downshift, push the selector lever
forward toward –.
In the automated mode all forward
gears are automatically shifted.
No automatic upshifting is carried out in
the sequential mode.

In the sequential mode you can choose
Gradient assistance
from six driving programs ranging from
balanced, dynamic driving – 1 – to
sporty, puristic driving – 6. The sporty,
puristic driving program can only be
activated with the Dynamic Stability
Control (DSC) deactivated, refer to
page 87.
The gradient assistance enables start-
ing off on grades with virtually no roll-
back. It can be activated in the sequen-
tial and automated mode with the vehi-
cle stopped and can be used for both
forward and reverse driving.
The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Drivelogic
Following each change between the
sequential and the automated mode,
the last driving program selected in the
Drivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the respective mode is active. Exception:
desired driving program is shown in the instead of the last selected sequential

SMG display of the instrument cluster,
refer to page 72.
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the gra-
dient assistance is activated
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
3. Release the footbrake and start off
within two seconds.
The gradient assistance must be reacti-
vated before each use.

Indicator lamp
Tire replacement, snow chains
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
Following a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG II must become familiar with the
changed condition.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be lim-
ited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Reinitialize the system afterwards:
1. Move the selector lever into
position 0 on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
Shift lights
To achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.
1. When the maximum engine speed is
approached, yellow indicator fields,
shift lights, in the tachometer light up
consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
