PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Audible signals and an optical display
* indicate
that you are approaching an object in front of or
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in each
bumper. The sensors at the front and at the two
rear corners have a range of approx. 24 in/
60 cm; the rear middle sensors have approx.
5ft/1.50m.
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 mode
In ignition key position 2, the system automati-
cally assumes operational status after approx.
1 second each time you shift into reverse or
move the selector-lever to position R.
Wait this short period before driving. The sys-
tem switches off when you disengage the
reverse gear.
Manual mode
Press the button; the LED lights up.
Deactivating manual mode
Press the button again; the LED goes out.
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 LED goes out. You can reactivate the sys-
tem manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
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 approx.
3 seconds if you are moving parallel to a wall.
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
PDC with visual warning*
You also enjoy the option of having the system
show the approach to an object on the Control
Display. The Control Display also indicates the
presence of objects before they are close
enough to trigger a signal tone.
Control Center, for principle details, refer to
page16.

To control
The indicator lamp flashes:
DSC or DTC controls the drive forces
and brake forces.
The indicator lamp comes on:
DSC and DTC are deactivated together via the
button DTC.
The indicator lamp comes on: DTC is
activated via the DTC button.
Malfunction in the driving-stability
control systems
The brake system warning lamp lights
up in red, appearing together with the
indicator lamps for ABS and DSC. A
message appears on the Control Dis-
play. The driving-stability control sys-
tems have failed. Conventional braking
efficiency remains available without
limitations.
While you may continue, you should remember
to proceed cautiously and drive defensively
while avoiding full brake applications.
Have the system checked as soon as possible.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem 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 and a mes-
sage appears on the Control Display.
There is a malfunction in the system.
Have the system checked as soon as possible.
If there is a malfunction in the system,
please remember to adapt your speed
accordingly, especially 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 message stating that you should stop
appears on the Control Display, stop and switch
off the engine as soon as possible. In this case
the oil level in the reservoir may have dropped
below the minimum, possibly owing to a leak in
the hydraulic system. Do not continue driving.
Contact your BMW center.<

Things to remember when driving
108
Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Up to 1,200 miles/2,000 km:
You should attempt to vary both vehicle and
engine speeds. Until the break-in period has
been completed, you should also refrain from
exceeding an engine speed of 4,500 rpm or a
driving speed of 100 mph/160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
Once you have driven 1,200 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased.
SMG Sequential manual transmission
Do not use the acceleration assistant during the
break-in period, refer to page59.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
After component replacement
You should also comply with these break-in
procedures should the components mentioned
above need to be replaced at a later point.
General driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed. Otherwise, exhaust fumes could pene-
trate to the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
luggage compartment lid open:
1.Coupe: close both windows and the glass
sunroof.
Convertible: with closed top, close all win-
dows.
2.Adjust the automatic climate control to sup-
ply a high air volume, refer to page95.
Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking, take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to a
fire, and with it the risk of serious property dam-
age as well as personal injury.<

Maintenance
The BMW Maintenance
System
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air. The
ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining times or distances of selected main-
tenance intervals and legally mandated dead-
lines, refer to page70:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally required tests depending on local
regulations
Your vehicle stores this information continu-
ously in the master key while the vehicle is
being driven. After accessing the data stored in
the master key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. You
should therefore give your BMW Service Advi-
sor the key you last used to drive when you take
your vehicle in for service.
Make sure the date in the Control Center
is always set correctly, refer to page78,
as otherwise the effectiveness of CBS Condi-
tion Based Service is not ensured.<

formed at your BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance, and may also be
required when submitting warranty claims.<

OBD Socket
The Onboard Diagnostics OBD interface
socket is located on the left of the driver's side
under the instrument panel and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to ensure
proper operation of the emission control sys-
tem for the vehicle's lifetime. The system mon-
itors emission-related components and sys-
tems for deterioration and malfunction.
An illuminated indicator lamp informs
you of the need for service, not of the
need to stop the vehicle. However, the
systems should be checked by your BMW cen-
ter at the earliest possible opportunity.
Display of the previously described
malfunction on Canadian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a rather
severe level of engine misfire. When this
occurs, you should reduce speed and consult
the nearest BMW center as soon as possible.
Severe engine misfire over only a short period
of time can seriously damage emissions control
components, especially the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can detect
the vapor leak and the indicator lamp will light
up. If the filler cap is subsequently tightened,
the indicator lamp should go out within a few
days.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.
