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 represents 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
highways or other high-speed thoroughfares.
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 to
downshift 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 as needed. This setting is also
maintained on steep stretches, but the vehicle
speed can fall below this on uphill grades if the
engine output is insufficient to maintain speed.
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
to which you may be accustomed, 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.<
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.
Applications
As with conventional cruise control systems,
active cruise control in no way diminishes or
substitutes for the driver's own personal
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. 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 interchanges, service/
parking areas or toll booths. It is also important
to regulate your vehicle's speed and distance
setting within applicable legal limits. Adapt the

Distance 3
This distance is always set when
the system is used for the first time
after starting the engine.
Distance 4
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance;
failure to do so can constitute an accident haz-
ard.<
Deactivating cruise control
Press the lever up or down. The displays in the
speedometer go out.
In addition, the system is automatically deacti-
vated:
>when the speed is reduced to below 20 mph
or 30 km/h due to a traffic situation
>when DTC is activated or DSC is deacti-
vated
>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 page72
>when you actuate the parking brake during
driving
>when you shift the transmission into posi-
tion NIf the system is deactivated, then it is nec-
essary for the driver to actively intervene
by braking and possibly swerving. Otherwise,
there is the danger of an accident.<
Background lighting
You can switch off the backlighting of the
speedometer and tachometer when the system
is deactivated if no other functions are being
displayed, e.g. the advance warning field in the
tachometer, refer to page75, or the route guid-
ance of the navigation system.
To do so, press the lever up or down for approx.
1second.

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.<
When your vehicle is actively following a vehicle
in front of you, if 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 may also result in accelera-
tion of your vehicle.
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 the transmission from drive/D to
neutral/N, or deactivates DSC. After any deacti-
vation, 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.Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not
detect 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 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

System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any objects always remains with the
driver. Even when sensors are involved, there is
a blind spot in which objects cannot be
detected. The system's detection of objects is
also subject to the physical limits that apply to
all forms of ultrasonic measurement, such as
those encountered with tow bars and trailer
couplings, as well as thin or wedge-shaped
objects. Low objects already indicated, such as
curb edges, may enter the blind spot of the sen-sors before or after a continuous audible signal
is given. Higher, protruding objects, such as
wall ledges, may not be detectable.
Loud noises from outside and inside the vehicle
may also prevent you from hearing the PDC's
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
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
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

Dynamic Drive
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Active stabilizers at the front and rear axles form
the basis for Dynamic Drive. Suspension com-
pliance adapts to suit driving conditions, vary-
ing from performance-oriented during corner-
ing to smooth and comfort-oriented when the
vehicle is traveling in a straight line. During vehi-
cle operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message appears on the Info Display.
A malfunction has occurred in the
Dynamic Drive system. Have the system
checked as soon as possible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.<
If a Check Control message indicates an oil loss,
stop as soon as possible at a suitable location
and switch off the engine. Do not continue driv-
ing, contact your BMW center.
Self-leveling suspension*
Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
appears on the Info Display.
A malfunction has occurred in the level control
system.
Stop driving and check the vehicle:
>The vehicle is considerably lower at the rear
than at the front, possibly also on one side,
at the rear left compared to the rear right.
>The ground clearance is reduced or the
driving comfort is noticeably reduced.
>The position of the vehicle is normal, but a
malfunction is indicated.
Drive to the nearest BMW center or a workshop
that works in accordance with BMW guidelines
and uses appropriately trained personnel. Drive
with appropriate caution in the meantime.
