SMG Sequential manual transmission*
and automatic transmission*
Your BMW is equipped with the convenience
starting feature. It is sufficient to turn the igni-
tion key only briefly to position 3 and then
release it right away. The system responds by
automatically engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages automati-
cally.
SMG Sequential manual transmission*
1.Press the brake pedal.
2.Engage selector-lever position N.
3.Start the engine.
If the engine does not start, engage the
last gear selected again, refer to instru-
ment cluster display, and then shift into posi-
tion N.<
Automatic transmission with
Steptronic*
1.Press the brake pedal.
2.Engage selector-lever position P or N.
3.Start the engine.
Switching off engine
Do not remove the ignition key while the
vehicle is rolling, as otherwise the steer-
ing wheel lock will immobilize the steering.
When leaving the vehicle, remove the ignition
key and lock the steering.
When parking on a downhill incline, apply the
handbrake, as otherwise the vehicle could roll
away.<
Manual transmission
1.Turn the ignition key to position 1 or 0.

is pressed, the Sequential mode is activated.
You can shift up and down using the shifting
paddles or the selector lever. You do not need
to remove your foot from the accelerator to do
so.
It is also possible to start off in second gear, e.g.
in slippery conditions.
D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
To switch from Sequential to Drive mode:
Briefly press the selector lever to the right
toward D.
Kick-down:
For rapid acceleration, e.g. passing, press the
accelerator pedal as far down as it will go: you
achieve maximum acceleration.To switch back to the Sequential mode: press
selector lever to the right again toward D or shift
using the shifting paddles or the selector lever.
Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-
tle, but engage the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Gear changes
Using selector lever
>To upshift, pull the selector lever back.
>To downshift, push the selector lever for-
ward.
Using shift paddles on steering wheel
>To shift up, pull one of the shift paddles.
>To shift down, press.
In the following situations, the SMG in the
Sequential mode assists you:
>Upshifts and downshifts are executed only
when they will res ult in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.

recommended for a performance-oriented driv-
ing style. It is engaged automatically when the
Dynamic Driving Control is activated, see
below.
When the selector lever is briefly moved for-
ward or back, the manual mode is activated and
the Steptronic shifts gear. The instrument clus-
ter shows M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
selected gear appears briefly in the instrument
cluster, followed by the current gear.
To use the automatic function again, move the
selector lever to the right into position D.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Cruise control:
The stored speed is reached more quickly
when it is requested.
Additionally with SMG:
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.

ired wiper activation.<
Cleaning windshield and headlamps
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting system is switched
on, the headlamps are also cleaned at regular
and appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to Washer fluid.
Do not use washers when the washer fluid res-
ervoir is empty, as otherwise the washer pump
will be damaged.<
Windshield washer nozzles
The windshield washer nozzles are automati-
cally heated in ignition key position 2.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always
observe the instructions for use provided on the
containers.<
Washer fluid reservoir
Capacity approx. 5.3 US quarts/5 liters
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order maintain the mixture ratio, mix
the washer fluid before filling.<
Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle maintains and stores the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g.when driving on winding roads,
in heavy traffic or in poor road conditions such
as snow, rain, ice, and loose road surface.<

cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
In addition to holding a steady cruising speed, if
you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that one can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
distance setting between your vehicle and the
vehicle ahead. There are four settings for dis-
tance, which are additionally speed-dependent.
Based on your selected distance setting, the
system automatically decreases the throttle
setting and lightly applies the brakes if neces-
sary. The vehicle brake lamps will automatically
illuminate to signal a following driver to take
action. In addition, it may be necessary for the
vehicle or the driver to downshift, depending on
the kind of transmission your vehicle is
equipped with, to maintain the distance setting
selected. If the vehicle ahead speeds up or
when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears automatically or by the driver as
needed.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
which you may be accustomed to, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section in this
manual beginning on page66. You can use the system in the 2nd to 6th gear
within a normal engine speed range and also
change gears. Continuous operation at very
high or very low engine speeds is not possible.
In this case the driver is asked to shift or the
system deactivates itself.
Vehicles with SMG
Continuous operation at very high engine
speeds is not possible in the Sequential mode.
In this case the driver is asked to shift or the
system deactivates itself.
In the Drive mode the SMG acts similarly to the
automatic transmission in the D position.

3Deactivate system
4Recall the stored speed and distance or
increase desired speed by 1 mph/1 km/h
with each press of the button
5Select distance to vehicle driving ahead.
You can choose from four available distance
settings. You will find more detailed infor-
mation on page65.
Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times. Great differences in speed to the vehi-
cles driving ahead, e. g. when quickly approach-
ing a truck or when another vehicle swerves into
your lane, cannot be compensated for by the
system.<
