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 exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the vehicle to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage 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
When shifting into 5th/6th gear, press the
gearshift lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could
lead to engine damage.<
Reverse gear
Select only when the vehicle is stationary.
Press the gearshift lever to the left, overcoming
a slight resistance.
Sport automatic
transmission*
In addition to the fully automatic mode, you can
also shift manually with Steptronic, refer to
page61.
You can also choose between two driving pro-
grams: Normal or Sport, refer to Dynamic Driv-
ing Control.

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, headlamps and
BMW Night Vision camera*
Pull the lever, arrow4:
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
With the vehicle lighting switched on, the head-
lamps and the BMW Night Vision camera are
also cleaned simultaneously at suitable inter-
vals.
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.
For this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always fol-
low the instructions for use provided on the
containers.<
Filler neck for washer fluid
All washer nozzles are supplied from one reser-
voir.
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.<
Capacity
Capacity approx. 5.3 US quarts/5 liters.
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. To maintain the specified speed, the sys-
tem brakes if the engine braking effect is not
sufficient on a downhill grade. Speed can drop
on uphill grades if the engine output is insuffi-
cient.
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.
Otherwise, you could lose control of the vehicle
and cause an accident.<

Especially on longer trips and in traffic conges-
tion, 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 limits, adjust your
vehicle's speed automatically so that you can
flow with the traffic without having to make con-
stant adjustments. If, for example, while cruis-
ing 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. You
can vary the following distance, which will vary
with speed. Based on your selected distance
setting, the system automatically decreases the
throttle setting and lightly applies the brakes if
necessary. In addition, if the vehicle ahead of
you slows to a complete stop, the system can
follow this action within the given scope and
can also accelerate from a complete stop if the
vehicle ahead of you drives off again shortly
thereafter. During braking, your vehicle brake
lamps will automatically illuminate to alert a fol-
lowing driver to take action. In addition, it may
be necessary for your vehicle to downshift the
automatic transmission to maintain the dis-
tance setting selected. As soon as the road in
front of you has no moving vehicles, the system
will accelerate to your desired speed. This set
speed is also maintained on downhill grades,
however the vehicle speed can drop below the
set speed when driving uphill if the engine out-
put is not sufficient.
Active cruise control cannot detect stop
signs, red lights, or any object that is
stopped or is blocking the road.
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 differently from con-
ventional cruise control systems which you may
be accustomed to, it is necessary that you read
all of the pages relating to this system before
use. Carefully read and observe the information on the system limitations beginning on page71
to obtain a good command of the system and its
range of applications.<
Brake pedal feel
When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.
Professional* navigation system
If a navigation DVD is in the drive, refer to
page132, within limits the system adjusts the
accelerating and braking behavior of the vehicle
to the road you are driving on.
To ensure that the system is informed of
the current course of the road, always use
the latest navigation DVD if possible.<
When the vehicle position is unknown, e. g.
when you leave the map area, this influence of
the navigation system is not available.
Applications
Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it
during normal traffic.
As with conventional cruise control systems,
active cruise control in no way reduces or sub-
stitutes for the driver's own personal experi-
ence, responsibility, alertness and awareness in
adjusting speed, braking or otherwise control-
ling 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 as well as in slow-moving traffic. Do
not use the system in city driving; in complex
driving situations; heavy traffic such as during
rush hour; on curvy, winding roads, slippery
roads or roads with sharp curves such as high-
way off-ramps; during inclement weather such
as snow, strong rain or fog; or when entering
interchanges, service/parking areas or toll
booths. It is also important to regulate your

68 vehicle's speed and distance setting within
applicable legal limits. Always be ready to take
action or apply the brakes if necessary, espe-
cially when the system is actively following a
vehicle in front of you. Otherwise, driving condi-
tions can result which lead to a violation of the
law or elevated risk of an accident.
The minimum initial activation speed is 20 mph/
30 km/h, and the maximum speed is 110 mph/
180 km/h. However, you can also activate the
system while stopped, refer to While stopped,
page70.

Selecting distance
>Briefly press rocker switch downward:
Increase distance.
>Briefly press rocker switch upward:
Reduce distance.
The selected distance is displayed in the instru-
ment cluster.
Use good judgment to select the appro-
priate following distance, given road con-
ditions, traffic, applicable laws and State driving
recommendations for safe following distance.
Otherwise, a violation of the law or risk of an
accident could result.<
Interrupting cruise control
Press the lever upward or downward, and with
the vehicle stopped also depress the brake
pedal. The marking in the speedometer
changes color and the distance indicator goes
out.
In addition, the system is automatically inter-
rupted:
>when you apply the vehicle brakes
>when you shift the transmission
>when DTC is activated or DSC is deacti-
vated
>when DSC comes on
>when you apply the handbrake
>when you release the safety belt and open
the driver's door with the vehicle stopped
>when the system does not recognize any
objects for an extended period of time, e. g.
on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page71
If the system is interrupted, then it is nec-
essary for the driver to actively intervene
by braking and steering. Otherwise, there is a
risk of an accident.<

matic transmission and apply the handbrake.
Otherwise the vehicle can roll.<
If a detected vehicle in front of you brakes to a
complete stop and your vehicle has also been
braked to a complete stop by the system:
>If the vehicle in front of you drives off while
the marking1 for the desired speed in the
speedometer is green, your vehicle will
accelerate without you having to do any-
thing.
>If the vehicle in front of you drives off while
the marking1 is orange, you briefly depress
the accelerator pedal or press button4.
Rolling bars in the distance indicator3
mean that the vehicle in front of you has
driven off.

Radar sensors
1Long-range sensor
2Location of the short-range sensors behind
the bumperHeavy rain and also dirt, snow or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper
as well as the bumper area covering the short
range sensors. When doing so, be particularly
careful in removing layers of snow and ice.
Do not apply adhesive labels etc. in the area of
the short-range sensors.
If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be
activated.
System limitations
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 free-
way-type roadways where traffic is moving rel-
atively smoothly. Do not use this system in city
driving; in complex driving situations; 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 interchanges, 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 nec-
essary, especially when the system is actively
following a vehicle in front of you.
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic,
pedestrians or other types of potential traffic
such as a rider on a 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 automati-
cally 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.<
Page 74 of 264
Driving
72 The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g. on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a freeway 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.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any inter-
ruption, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings.<
Active cruise control may brake when you
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.
Unexpected lane change
If a vehicle in front of you is behind a stopped
vehicle and unexpectedly changes lanes, you
must react yourself, as the system does not
react to stopped vehicles.
Swerving vehicles
When a vehicle swerves out of adjacent lanes
into your lane, the system does not detect the
vehicle until it is completely in your lane.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to restore the selected distance automatically.
This also applies to great differences in speed
between your vehicle and vehicles ahead, e. g.
when quickly approaching a truck. Once the
system has established that a vehicle is indeed
in front of you, it will indicate that you must
brake and/or maneuver the vehicle yourself.
Take action yourself, otherwise there is a risk of
an accident.<

Behavior in curves
If the selected desired speed for a curve is too
high, the system reduces the speed within a
curve. However, it cannot detect curves in
advance. Therefore, select a suitable speed at
the start of a curve.
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 might 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 and your
responsibility
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted and the dis-
tance indicator turns off until the pedal is fully
released. As soon as you fully release the accel-
erator, the system will once again control your
cruising speed and distance setting. While driv-
ing with the system activated, resting your foot
on the accelerator pedal will cause the system
not to brake even if necessary. Be certain that
floormats or other objects on the vehicle floor
do not interfere with movement of the accelera-
tor 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. It
uses only a portion of braking system capacity
and does not utilize the full capacity of the vehi-
cle braking system. Therefore, the system can-
not decrease your speed due to large differ-
ences in speed between your vehicle and the
vehicle ahead. Example: 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.<

Electronic brake-force distribution
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adaptive brake assistant*
In conjunction with the active cruise control
with the stop-and-go function, the adaptive
brake assistant ensures that the brake
responds even more quickly during braking
with the brake assistant.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle safely stay on
course within the physical limits by reducing the
engine output and by applying the brakes differ-
ently in the individual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not restrict the additional
safety margin with a risky driving style, as other-
wise there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated
together. Interventions promoting stability and
forward momentum will no longer be carried
out. The stability-promoting intervention of the
active steering
* is also deactivated, refer to
page93.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To support enhanced operating stability, reacti-
vate DSC again as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a variant of DSC for special road condi-
tions, e.g. uncleared snow-covered roads, that
is optimized for forward momentum. The sys-
tem ensures maximum forward momentum, but
with limited driving stability. Therefore, drive
with appropriate caution.
