Sequential M gearbox SMG II*The conceptThe 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
>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
>Operating safety through protection
against misshifting.Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
Selector lever positionR: Reverse position
0: Position 0 (Neutral)
Forward position with one-touch mode:
>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.

Display in instrument clusterThe selector lever position, currently
engaged gear and selected driving pro-
gram are displayed in the instrument
cluster.
1Engaged gear
2Selected driving program, corre-
sponds to the number of illuminated
fields, refer to page 74
3Tapping the selector lever to the right
switches over into the displayed shift
mode
4"A" indicates an activated automated
shift mode
R – Reverse positionOnly 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.
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.S – Sequential modeIn the sequential mode all forward
gears are to be shifted by the driver.
Changeover from automated to
sequential mode:
>Tap the selector lever to the right
toward S or
>Change gears with the selector lever
or the shift paddles on the steering
wheel.
You do not need to reduce the throttle
for shifting.

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward +
>To downshift, push the selector lever
forward toward –.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the SMG II
helps you think in the sequential mode:
>Upshifts and downshifts are only exe-
cuted when the new gear will provide
a suitable combination of vehicle and
engine speed, i.e., downshifts that
would cause the engine to overrev
will not be executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached with-
out you taking any action.A – Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are automatically shifted.Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward A. Watch the display in
the instrument cluster, refer to page 72.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts in dependence on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

DrivelogicDrivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 72.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
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.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active. Exception:
instead of the last selected sequential
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
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.<
Gradient assistanceThe 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.<
1. Depress footbrake with vehicle
stopped
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
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within two seconds.
The gradient assistance must be reacti-
vated before each use.

Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>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.
Shift lightsTo 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.
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.
Tire replacement, snow chainsFollowing 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.
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.
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.

Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use a wind-
shield washer antifreeze in cold
weather. Refer to page 124.
Do not use the washers when the reser-
voir is empty. This could cause damage
to the washer pump.<
The system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
When the vehicle's lighting system is
switched on, the headlamps will also be
cleaned at reasonable intervals.Windshield washer nozzlesThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.
Cruise controlStarting at about 20 mph / 30 km/h, you
can maintain and store any vehicle
speed that you specify.
The cruise control is operational when-
ever the engine is running and the sys-
tem has been activated.To activate the systemWith the ignition key in position 2 or
higher:
Press the button. The indicator lamp in
the instrument cluster comes on, refer
to page 20. You can now use the cruise
control.
Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.

Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.To store and maintain speed or to
acceleratePress button "+" briefly:
The system stores and maintains the
current vehicle speed. Every time you
tap the button, the speed increases by
0.6 mph / 1 km/h.
Press and hold button "+":
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
stores and maintains the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button "–" briefly:
When cruise control is active, every tap
of the button reduces the speed by
approx. 0.6 mph / 1 km/h.
Press and hold button "–":
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system stores
and maintains the current speed.To interrupt the cruise controlEach time zou activate the system,
press the button. The indicator lamp
stays on. You can use the cruise control
again whenever you want by calling up
the speed that was stored last.
In addition, cruise control is interrupted
automatically:
