2.Briefly press Start/Stop button.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If it becomes necessary under special cir-
cumstances to use the handbrake while
driving, it must not be pulled too sharply. In
doing so, continuously press the button of the
handbrake lever. Otherwise strong application
of the handbrake can lead to overbraking of the
rear axle and associated 'fishtailing' of the vehi-
cle rear end.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<

SMG Sequential Manual
Gearbox*
The concept
The SMG Sequential Manual Gearbox is an
automated manual transmission in which an
electrohydraulic system handles the clutching
and gear changes.
You operate SMG with the selector lever in the
center console and two shift paddles on the
steering wheel.
It offers you the following functions:
>Optional manual or automatic operation:
Sequential mode or Drive mode
>You have a choice of two driving programs:
Normal or Sport, refer to Dynamic Driving
Control page60
>Automatic downshifting and prevention of
incorrect shifting even in sequential opera-
tion
>Acceleration assistant, refer to page61.
Selector lever positions
The current selector lever position is displayed
on the center console.
>R: Reverse gear
>N: Neutral>One-touch functions for Sequential mode:
+: manual upshifting
–: manual downshifting
>D: activate/deactivate the Drive mode
The transmission automatically shifts
into N if the driver's door is opened with
the engine running and neither the pedals, the
shift paddles nor the selector lever are oper-
ated.
This is indicated by an acoustic signal and the
flashing display N in the instrument cluster.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, pre-
ceded by a D in Drive mode.
It is only possible to recognize whether
the desired selector lever position is
engaged with this display.<
Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
After every engine start, as soon as the selector
lever is pushed to the right and the brake pedal
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.

Driving
60 It is also possible to start off in second gear, e. g.
in slippery conditions.
In the following situations, SMG thinks for you:
>Upshifts and downshifts are executed only
when they will result 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.
D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D.
Kick-down: for rapid acceleration, e. g. when
passing, press the accelerator pedal as far
down as it will go. You achieve maximum accel-
eration.
To switch back into 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 pressing the accel-
erator, but apply 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 upshift, pull one of the shift paddles.
>To downshift, press.
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.
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
>Cruise control
*:
The stored speed is reached more quickly
when it is requested.

Sport program and
manual operation M/S
Move selector lever from position D toward the
left into the M/S shifting slot:
The sport program is activated and DS appears
in the instrument cluster. This position is rec-
ommended for a performance-oriented driving
style.
When the selector lever is pressed forward or
back, the manual mode is activated and the
Steptronic shifts the 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.

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
washing mechanisms when the washer fluid
reservoir is empty, otherwise you will damage
the washer pump.<

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
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to 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 stores and maintains 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 roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi-
cle and cause an accident.<

Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is technologically
advanced over the familiar cruise control and is
a welcome relief from the constant adjustment
of speed that can accompany driving in traffic
on freeways or other high-speed thorough-

Driving
66 fares. Especially 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 you 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. You can vary the distance, which
is additionally speed-dependent. Based on
your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, 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 vehicle will acceler-
ate to the speed you have selected by increas-
ing the throttle setting and shifting gears auto-
matically or by the driver as needed. Your
selected speed will be held when driving down-
hill, too.
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 begin-
ning on page69.<
Navigation system Professional*
If a navigation DVD is in the drive, refer to
page124, the system adjusts the accelerating
and braking behavior of the vehicle to the road
you are driving on.
When the vehicle position is unknown, e.g.
when you leave the map area, this influence of
the navigation system is not available.
Manual transmission
You can shift with the cruise control activated.
Shifting information is provided or the system
deactivates itself if you drive at very high or very
low engine speeds for a longer period.
SMG
In the Sequential mode, shifting information is
provided or the system deactivates itself if you
drive at very high engine speeds for a longer
period.
In the Drive mode the SMG acts similarly to an
automatic transmission in the D position.
