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.
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.
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 acceleration.
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.
In the following situations, the SMG in Sequen-
tial mode assists 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.
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.

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
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 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.<

4Resuming stored speed
Maintaining speed, storing speed, and
accelerating
Press lever to resistance point 1:
The speed currently being driven is maintained
and stored. The display1 in the speedometer,
refer to page59, indicates this regulated speed.
Every time you press the lever, the vehicle's
speed increases by roughly 1 mph/1 km/h.
Press lever to resistance point for a longer time:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever beyond the resistance point:
increase speed by 5 mph/10 km/h.
The vehicle may accelerate beyond the regu-
lated speed on steep downhill stretches where
the engine's braking effect alone may not be
sufficient to slow the vehicle. Speed can drop
on uphill grades if the engine output is insuffi-
cient.

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 a technological advance
over the familiar cruise control and is a welcome
relief from the constant adjustment of speed
that can accompany driving in traffic on free-
ways or other high-speed thoroughfares. Espe-
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 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. 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.

Driving
60 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 page62.<
Vehicles with manual transmission
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.

5Select distance to vehicle driving ahead.
You can choose from four available distance
settings. You will find more detailed infor-
mation on page62.
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.<

The system requests that you
intervene by braking or with an
evasive maneuver. The display 2
flashes red and a signal sounds.
The active cruise control cannot
automatically restore the distance to the vehicle
driving ahead. You will find more detailed infor-
mation on page. You will find more detailed
information on page64.

now only intervenes by braking.
Desired speed, store and increase
Press the lever forward 1 at a driving speed of
more than approx. 20 mph/30 km/h:
The system applies and stores your current
speed as a desired speed. This speed is indi-
cated on the speedometer and displayed briefly
in the instrument cluster.
Subsequently pressing forward increases the
desired speed to the next multiple of 5 mph/
10 km/h. Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed then
displayed is stored and achieved, provided that
the road is clear.
If the display ACC --- mph/km/h briefly
appears in the instrument cluster, it might
be that conditions necessary for operation are
not currently being met.
To call up Check Control messages, refer to
page67.<
Desired speed, store and decrease
Pull back the lever 2:
The current driving speed is rounded off to the
next multiple of 5 mph/10 km/h, displayed and
stored.
Each time the lever is pulled back again, the
desired speed is decreased by another 5 mph/
10 km/h until the minimum speed of 20 mph/
30 km/h is reached. The speed then displayed
is stored and achieved, provided that the road is
clear.
Deactivate system
Press the lever up or down while the system is
active 3. The displays in the instrument cluster
disappear. You can use the system again as
required.
In addition, the system is deactivated automati-
cally:
>When you apply pressure to the brake pedal
>When you select the automatic transmis-
sion's/SMG's neutral position N
>When the manual transmission is shifted
into neutral
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the handbrake during
driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic situ-
ation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. An acoustic signal sounds and a mes-
sage appears on the Control Display. The active
intervention of the driver is required.<
When you switch off the ignition, the stored
desired speed is deleted.
Resume stored desired speed and
distance setting
Press button 4 when the system is deactivated.
The displays appear in the instrument cluster.
The system is reactivated and uses the last
stored desired speed and distance setting.

Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
