sounds. The active cruise con-
trol cannot automatically restore the dis-
tance to the vehicle driving ahead. You will
find more detailed information on page 64.

Always remember that the range and
ability of the system does have phys-
ical limitations. It will not apply the brakes
or decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these
situations as the system will neither auto-
matically 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 alert-
ness.<
If while 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 vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
structed 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 man-
ner 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 system 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
deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, 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 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 intervene 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
canceled.
Behavior in curves
Because of the limited range of the system,
it is possible that in curves or on the peaks
and valleys of hilly roads, a vehicle ahead
may be recognized late, or not at all. There-
fore, 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 vehi-
cle decelerates in either case, you can

Fuel gauge
After the reserve quantity has been
reached, a message appears for a short
time on the Control Display; the range is
shown in the computer. Below a range of
approx. 30 miles/50 km, the message
remains on the Control Display, and the
range is displayed.
Fuel tank capacity: approx. 18.5 gallons/
70 liters, of which approx. 2.1 gallons/
8 liters reserve. You can find information on
Refueling on page 168.
If the tilt of the vehicle varies for a longer
period, when you are driving in mountain-
ous areas, for example, the indicator may
fluctuate slightly.
Refuel well before the tank is empty,
as otherwise engine functions will not
be ensured and damage can occur if you
drive down to the last drop.<

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones indicate the current distance
to an object behind or in front of your vehi-
cle. Four ultrasonic sensors in both the
bumpers monitor the distance to the near-
est object. The sensors at the front and at
the two rear corners have a range of
approx. 1.64 ft/50 cm; the rear middle sen-
sors have approx. 5 ft/1.50 m.
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,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic function
In ignition key position 2, the system auto-
matically assumes operational status after
a few seconds each time you engage
reverse gear or selector-lever position R.
Wait this short period before revers-
ing.<
Manual activation
Press the button, the indicator lamp lights
up.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Automatic deactivation
The system is automatically deactivated
once the vehicle travels approx. 165 ft/
50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become
shorter. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds when the distance to an
object remains constant during this time,
if you are moving parallel to a wall, for
instance.
Malfunctions
The indicator lamp within the button
flashes and a message appears on the
Control Display. Please note any supple-
mentary information that appears there.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center.
PDC with visual warning*
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display for the specific key in use. The

is displayed with the PDC image
switched on.
The display then appears on the Control
Display as soon as PDC is automatically
activated.
The previous display automatically reap-
pears after the system is deactivated.
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions 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 ultrasonic measurement,
such as those encountered with thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside your
vehicle may prevent you from hearing the
PDC signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control/
ABS Antilock Brake System
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS and DSC.
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
The ABS is operational every time you start
the engine. ABS includes the functions
CBC Cornering Brake Control and EBV
Electronic Brake Force Distribution.
In case of malfunction
If the indicator lamp lights up in yel-
low, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.

Technology for comfort, convenience and safety
78
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic Brake Force
Distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
In case of malfunction
If the brake system warning lamp
lights up in red, appearing together
with the yellow indicator lamps for
ABS and DSC:
The driving stability control has
failed.
If all three lamps light up yellow:
Fault in the driving stability control.
The EBV electronic brake-force distribution
is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
If a message appears on the Control Dis-
play, please note the supplementary infor-
mation.
You can find more information on the
Check Control starting on page 68.
Indicator and warning lamps for
Canadian models.
Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control, refer to
page 79.
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction. The
system recognizes any tendency for the
vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
Indicator lamps
The indicator lamp in the instrument
cluster goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC is regulating the drive and braking
forces.
If the indicator lamp lights up permanently:
DSC has been switched off using the but-
ton.
If the indicator lamp and the brake
warning lamp light up permanently:
Malfunction in DSC, DTC and DBC.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.
