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. 2 ft/60 cm; the rear middle sensors
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
Whenever the ignition is on the system
automatically assumes operational status
after a few seconds each time you engage
the transmission 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 if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a status message appears in
the Check Control.
Please take note of the additional informa-
tion on the Control Display.
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. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm. This activates the PDC dis-
play.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically
reappears after the system is deactivated.
Confirming the menu item takes
you back to the previous display.<
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 tow bars and trailer couplings, as well as 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 the
vehicle may prevent you from hearing
PDC's 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
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
In case of malfunction
If the indicator lamp lights up in
yellow, 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.
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.

Technology for comfort, convenience and safety

In case of malfunction
If the brake system warning lamp
lights up in red, together with the
yellow indicator lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems. The 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.
Check Control messages, refer to page 82.

Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
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 optimized stability within the limits defined by the
laws of physics.
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.
Indicator lamps
The indicator lamp in the Info Dis-
play goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
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.

DTC Dynamic Traction Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.

Dynamic Drive
The concept
Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.
Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-
oriented when the vehicle is proceeding in
a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display.
You can find more information on the
Check Control starting on page 82.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-dency to tilt during cornering and in cross-
winds.
If a Check Control message stating that
you should stop appears in addition to the
red symbol, stop immediately and switch
off the engine. In this case the oil level in
the reservoir may have dropped below the
minimum, possibly owing to a leak in the
hydraulic system.
Please observe the additional instructions
provided on the Control Display.<
EDC Electronic Damping
Control*
The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.
Two programs are available; they can be
selected in the "Settings" menu.
Comfort program
The Comfort program is suitable for use
throughout the vehicle's entire speed range
and regardless of load.
Sport program
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and steer-
ing.

In the event of malfunction
A Check Control message appear-
ing together with this symbol indi-
cates a malfunction in the self-lev-
eling suspension. Please take note of the
additional information on the Control Dis-
play.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, please respond by immediately
proceeding to the nearest BMW center.
Drive with appropriate caution in the mean-
time. The vehicle has reduced ground
clearance and driving comfort may be
noticeably reduced. Even if the attitude of
the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
Brake force display
The Brake force display indicates the inten-
sity with which you are applying your
brakes to drivers of following vehicles.
The display consists of two stages:
>Normal braking:
The brake lamps in the tail lamp assem-
blies and the high-mount brake lamp on
the rear tray light up during braking
>Heavy braking and braking with ABS:
The tail lamps also light up with the
same intensity as the standard brake
lamp units to enhance the warning
effect of the brake lamps.

Parking lamps/low beams
Parking lamps
With the switch in this position, the
front, rear and side vehicle lighting
is switched on. You can use the
parking lamps for parking. For lighting on
one side for parking as an additional fea-
ture, refer to page 100.
Low beams
When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.
Pathway lighting:
After parking the vehicle and switch-
ing off the headlamps, you can use the
headlamp flasher control to activate
the low beams for a period of roughly
40 seconds. You also have the options of
extending this period or, as an alternative,
having this function deactivated.<
Lights on warning
If you switch off the ignition while the head-
lamps are on, when you subsequently open
the driver's door a gong will sound for sev-
eral seconds, while the Check Control will
provide you with a message
.
Daytime driving lamps*
If you wish, you can leave the light switch in
the low-beam position. Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
You can have the daytime driving
lamps on your vehicle programmed to
operate as desired.<
Automatic headlamp control
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in tunnels, at dawn
and dusk, and in rain and snow. The green
indicator lamp next to the symbol is illumi-
nated when the low beams are on.
Following automatic activation, the
vehicle's external lighting remains on
when you switch on the fog lamps.<
The automatic headlamp control can-
not serve as a substitute for your per-
sonal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For exam-
ple, the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
You can have the sensitivity of the
headlamp control system adjusted on
your vehicle.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumi-
nation of the road surface. Depending on
the steering angle and other assumptions,
the light from the headlamp follows the
course of the road.

to as hydroplaning, and is characterized
by a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Brake system
Braking with ABS
The best way to achieve the best response
from the ABS is to apply maximum pres-
sure to the brake pedal Ð panic stop. Since
the vehicle maintains steering responsive-
ness, you can nevertheless avoid possible
obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Disc brakes
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear
in the automatic transmission's manual
mode, downshifting as far as first gear
on extremely steep stretches, refer to
page 67. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral Ð or with
the engine switched off Ð as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.
Brake pads
If the brake pad wear warning lamp
appears in the Check Control,
accompanied by a text. Please take
careful note of the additional information on
the Control Display.
