Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1
,
until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
> Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
> Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph or 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Deactivating cruise control
Briefly press the lever upwards or downwards,
arrow 3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
> when the brakes are applied.
> when the manual transmission is shifted
very slowly or shifted into neutral.
> when the automatic transmission selector
lever is moved into the neutral position.
> when the selector lever of the sport auto-
matic transmission with double clutch is
moved into the neutral position.
> when DTC is activated or DSC is deacti-
vated.
> when DSC or ABS is intervening. Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.

Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Dis-
play.The cruise control is malfunc-
tioning. You can continue your journey. Have
the system checked.
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
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.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is 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 illuminate to sig-
nal 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 trans-
mission your vehicle is equipped with, to main-
tain 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 by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this Active Cruise Control system is a
new technology and operates differently from
conventional cruise co
ntrol 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 System
limitations section beginning on page 78.
Braking sensation
> If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be
slightly different from the usual.
> Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110mph or 180km/h.
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-

When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary; otherwise, there is a
risk of accidents.<

System limitations
Always remember that the range and abil-
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, 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. The system may also not detect
smaller moving objects such as motorcycles or
bicycles. Be especially alert when encountering
any of these situations as the system will nei-
ther 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. <
Active Cruise Control is not and must not
be used as a collision avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle 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. 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

tions will be given of some equipment that may

functions and systems.
Park Distance Control PDC
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator warn you of the presence of an object
in front of or behind your vehicle.To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the front sensors and rear corner sensors,
or approx. 5 ft/1.50 m from the rear center sen-
sors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the
system warning being issued too late. <
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. one
second when you shift into reverse or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 160 ft/50 m of driving or above
approx. 20 mph or 30 km/h km/h, the system
switches off and the LED goes out.
Switching on manually
When parking in the forward direction, the sen-
sors must be switched on manually to enable
them to signal an approach to an object in front
of or behind the vehicle.
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, if an object is detected behind the vehicle,
the signal tone sounds from the rear. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds
>If you remain in front of an object that has
been detected by only one of the corner
sensors
> If you are driving parallel to a wall.

Technology for driving comfort and safety
Controls
Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Display.
PDC is malfunctioning. Have the sys-
tem checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page138.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
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 for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual 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 reduce the additional
