Switching engine off
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering-wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, engage the
handbrake, otherwise the vehicle could roll
away.<

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 engaged.
Indicator lamp for Canadian models.
Engaging
The lever engages automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to engage the hand-
brake while the vehicle is in motion, do not pull it
too strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise,
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
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 engaged.<
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.<

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 also speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically light up 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 transmis-
sion 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 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 also be held when driving
downhill, however it can be dropped below
when driving uphill if the engine output is insuf-
ficient.
The minimum desired speed is 20 mph or
30 km/h, and the maximum desired speed
110 mph or 180 km/h.
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 page72.<
Professional* navigation system
If a navigation DVD is in the drive, refer to
page128, 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.<
The influence exerted by the navigation system
is canceled when the vehicle position is
unknown, e.g. when it has left the mapped
region.
Brake pedal feel
>When the system brakes and you also
depress the brake pedal, a somewhat differ-
ent braking feeling results.
>Any noises produced during automatic
braking are normal.
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.

Use good judgment to select the appro-
priate following distance, given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for a safe following distance.<
Deactivating 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 Trac-
tion Control
>when you deactivate the DSC Dynamic Sta-
bility 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 page72
>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.<
Resuming stored desired speed and
distance
Press button 4.
The displays appear in the instrument cluster.
When you switch off the ignition, the stored
desired speed is deleted.

4Selected desired speed appears briefly
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 Con-
trol messages, refer to page80.<
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.

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. ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
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.<
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.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

Driving
74 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 due to large differences 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.<

System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e. g. curbs, can also disap-
pear from the detection area of the sensors
again before or after a continuous tone already
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC signal
tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page123.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.
Electronic brake-force distribution
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.
DBC Dynamic Brake Control
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.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. DSC also
detects unstable driving conditions such as
fishtailing or sliding of the vehicle's 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 differently 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. Do not reduce the additional safety mar-
gin of the system by taking risks.<
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
page95.
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.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
