toolkit, refer to page197, press the lever at
the point marked in red and move the selec-
tor lever into the desired position.
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 requested.
Additionally with SMG:
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
With automatic transmission:
>The Sport program is activated.
Activating system
With the ignition switched on, press the SPORT
button.The LED in the button lights up and SPORT is
displayed in the instrument cluster.
Deactivating system
>Press the SPORT button again or
>shift into reverse or
>switch off the engine.
The LED in the button and SPORT in the instru-
ment cluster go out.
Acceleration assistant with SMG
The acceleration assistant enables optimized
vehicle acceleration at race car level on road
surfaces with good adhesion when starting off.
Do not use the acceleration assistant too
often; otherwise, components will wear
prematurely.<
1.Activate the Dynamic Driving Control.
2.Deactivate DSC, refer to page87.
3.Press the accelerator pedal down fully:
Kick-down. The ideal starting-off engine
speed is set.
To maintain the vehicle stability, reacti-
vate DSC afterward.<

Turn the knurled wheel5.
Deactivating rain sensor
Press the button again, arrow3. The LED goes
out.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
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 reservoir is
empty, as this will damage the washer pump.<
Windshield washer nozzles
Both windshield washer nozzles are automati-
cally heated with the engine running or the igni-
tion switched on.
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
follow 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 to maintain the mixture ratio, mix
the washer fluid before filling.<
Cruise control
The concept
Cruise control is available for use at speeds of
approx. 20 mph/30 km/h and higher. The vehi-
cle 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 lose control of the vehicle
and cause an accident.<

Press lever to resistance point, arrow 1:
The system maintains and stores the current
vehicle speed. The display1 in the speedome-
ter, see below, indicates this regulated speed.
Every time you briefly press the lever, the vehi-
cle speed increases by approx. 1 mph/1 km/h.
Press the lever to the resistance point and hold
it:
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:
The speed increases by 5 mph/10 km/h.
The vehicle may accelerate beyond the regu-
lated speed on steep downhill stretches where
the engine's braking action 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 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
68 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 maintaining a steady cruising
speed, active cruise control will, within the
scope of given possibilities, adjust your vehi-
cle's speed automatically if you encounter
slower vehicles ahead, thus allowing you to flow
with the traffic without having to make frequent
interventions. For example, if, 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 main-
tain your selected distance setting between
your vehicle and the vehicle ahead. You can
vary the distance, which is also speed-depen-
dent. 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 with the aid of
the driver as needed. Your selected speed will
be maintained when driving downhill, 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 page71.<
Professional* navigation system
If there is a navigation DVD in the player, refer to
page120, then the system adapts the acceler-
ation and deceleration behavior of the vehicle to
the road on which you are currently driving.
The influence exerted by the navigation system
is canceled when the vehicle position is
unknown, e.g. when it has left the mapped
region.
Manual transmission
You can shift gears with the cruise control acti-
vated. If you drive for extended periods at very
high or very low engine speeds, then a shifting
command is issued or the system is deacti-
vated.
SMG
If you drive for extended periods at very high
engine speeds in Sequential mode, then a shift-
ing command is issued or the system is deacti-
vated.
In the Drive mode, the SMG acts similarly to an
automatic transmission in the D position.

Deactivate system
Press the lever up or down. The displays in the
instrument cluster disappear.
You also deactivate the system when you apply
the brakes, shift very slowly, or shift into neutral.
In addition, the system is deactivated automati-
cally:
>when you activate the DTC Dynamic
Traction Control
>when you deactivate the DSC Dynamic
Stability Control>when the system does not recognize any
objects for a longer time, e. g. on infre-
quently traveled roads without a shoulder or
guard rails, or if the radar sensor is covered
with dirt, refer to page71
>when the speed is reduced to below
20 mph/30 km/h due to a traffic situation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. A signal sounds and a message
appears in the Control Display. The active inter-
vention of the driver is required, otherwise there
is the danger of an accident.<

trol messages, refer to page79.<
Warning lamps
The display2 flashes red and a sig-
nal sounds.
The system is warning you to inter-
vene by braking or executing an
evasive maneuver. The active
cruise control cannot automatically restore the
distance to the vehicle driving ahead.
This display does not, however, relieve the
driver of the responsibility for adapting desired
speed and driving style to traffic conditions.
The display2 flashes yellow.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
actively take over.
Radar sensor
Heavy rain, dirt, snow, or ice can impair the
detection of vehicles ahead. If necessary, clean
the radar sensor under the front bumper. In
doing so, be especially careful when removing
layers of snow and ice.
If the sensor is incorrectly aligned, the active
cruise control cannot be activated.
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,
heavy 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.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. It will not apply the brakes or decelerate

Driving
72 your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that
every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
If your vehicle is actively following a vehicle in
front of you and the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts into neutral, or deactivates DSC.
After any deactivation, the system will no longer
automatically activate the vehicle brakes, which
means the driver must intervene and resume
manual braking. You should then reactivate the
system only when you are fully aware of the
prior speed and distance settings. reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.

In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Driver interventions
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with the system activated, resting your
foot on the accelerator pedal will cause the sys-
tem not to brake even if necessary. Be certain
that floormats or other objects on the vehicle
floor do not interfere with movement of the
accelerator pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e. g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range.<
