Technology for comfort, convenience
and safetyPDC Park Distance Control*

The concept The PDC assists you when you are parking.
Acoustic signals inform you of the distance
to an obstacle. Four ultrasonic sensors in
both the front and rear bumpers monitor
the distance to the nearest object. The
monitoring range of the front and two rear
corner sensors extends outward roughly
2 ft (60 cm), while the rear bumper's two
centrally located sensors detect objects at
distances of up to approximately 4.9 ft
(1.50 m). Automatic function Whenever the ignition is on the system
automatically assumes operational status
each time the selector lever is pressed
briefly in R. Manual activationPress the button, the indicator lamp lights
up.
The system is automatically deactivated
once the vehicle travels approximately
165 ft (50 m) or exceeds a speed of roughly
18 mph (roughly 30 km/h); the indicator
lamp goes out. You can reactivate the
system manually as needed.
Manual deactivation Press the button again; the indicator lamp
goes out. Acoustic signals The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the
vehicle 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
continuous once the distance to the
nearest object falls to below roughly 1 ft
(30 cm).
The warning signal is canceled after
approximately 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 status message appears in
the Check Control panel.
Please take note of the supplementary
information provided in the Control Display.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center. PDC with visual alert

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.

Activating DTC Dynamic Traction
Control You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting off
in deep snow or on loose road surfaces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now acti-
vated. The "DTC" indicator lamp in the
Control Display lights up.
When DTC is operating, DSC is
restricted to limited functionality up
to vehicle speeds of approx. 45 mph (70 km/h). Control intervention to maintain
stability is reduced.<
To deactivate DTC again Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now deacti-
vated. The "DTC" indicator lamp in the Info
Display goes out. To deactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is deactivated.
The indicator lamp in the Info Display
remains on continuously.
Deactivating DSC automatically deacti-
vates DTC as well. The systems for
enhancing stability and traction are deacti-
vated, and there is no active braking inter-
vention or torque control.
A status report appears in the Check
Control panel. Please take note of the addi-
tional information in the Control Display
panel.
To maintain optimal stability, drive
with the system on whenever
possible.< To reactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is now on. The
indicator lamp in the Info Display goes out.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Avoid using the
additional safety margin provided by the
system as an excuse for taking unneces-
sary risks.
When DTC is active, DSC provides only

limited system response up to a speed of
approx. 45 mph (70 km/h). Intervention for
stability-enhancement is reduced. Do not
make any modiÞcations to the DSC system.
Never allow anyone other than authorized
professional technicians to carry out
service or repairs on the DSC system.< 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 shortest possible
braking distance during "panic stops." This
system exploits all of the benefits provided
by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.
In the event of a malfunction, the
warning lamp comes on with a
yellow lamp. Have the system
checked and repaired at your BMW center
as soon as possible.
Check Control messages, refer to page 80.
Please note the supplementary information
provided in the Control Display.

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.
Cornering Brake Control CBC CBC is a technical advance based on ABS.
It provides further enhancements in vehicle
stability and steering response during lane
changes and cornering at high rates of
lateral acceleration. 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 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.
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.

In the event of loss in tire pressure If the indicator lamp symbol in the Check
Control lights up in yellow, and a message
also appears, this indicates that the infla-
tion pressures in the tires have fallen to
below the specified level, which is normal
in every tire after a certain amount of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible.
Please take note of the additional informa-
tion in the Control Display panel.
If you are prompted to check the tire
pressure shortly after a correction has
been made, this indicates that the
corrected values were not accurate. Please
check the inflation pressure again and
make corrections according to the inflation
pressure table. Then reinitialize the
system.< Flat tire If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. Replace the damaged tire.
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support RDC operation;
once the spare tire is installed, the pressure
in this tire will also be monitored following
system initialization.
Have the tires changed at your BMW
center. Your BMW center has the informa-
tion needed for working with RDC and is
equipped with the necessary special
tools. radio frequency as RDC can generate inter-
ference signals that may prevent the
system from operating as intended. The symbol will appear in yellow in the
Check Control panel and a message will
appear.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, additional
wheels with RDC electronics are on board.
Please refer to the additional information
supplied in the Control Display, and have
the system inspected at your BMW center.
Self-leveling suspension*

In the event of malfunction
A Check Control message
appearing together with this symbol
indicates a malfunction in the self-
leveling suspension. Please take note of
the additional information in the Control
Display panel.
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, you should respond by immedi-
ately proceeding to the nearest BMW
center. Drive with appropriate caution in
the meantime. 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.
Adaptive brake lamp The adaptive brake lamp indicates the
intensity with which you are applying your
brakes to drivers of following vehicles.

Checking coolant level Correct coolant level with the engine cold Ð
approx. 58 7 (20 6):
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct when the
coolant extends to between the MIN and
MAX marks on the filler neck, refer to the
diagram adjacent to the filler neck
3.If the coolant is low, slowly add coolant
up to the specified level Ð do not overfill. Brake fluid
The symbol lights up and a
message appears in the Check
Control panel:
The brake fluid in the reservoir has fallen to
below the minimum level.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the
source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved DOT 4 brake fluids.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time.
To ensure that the brake system continues
to provide safe and reliable performance,
remember to have the brake fluid changed
every two years at the latest, refer to
page 79 and to the Service and Warranty
Information Booklet (US models) or the Warranty and Service Guide Booklet
(Canadian models).
Brake fluid is toxic and also damages
vehicle paintwork. Always store brake fluid
in tightly-closed original containers kept
well away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.<
Always observe all applicable envi-
ronmental rules and regulations when
disposing of used brake fluid.<
A low brake-fluid level combined with
longer-than-usual pedal travel could be a
sign that one of the brake system's
hydraulic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a
substantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accord-
ingly.<
