Malfunction
The indicator lamp in the button flashes and a
short continuous tone sounds. PDC is malfunc-
tioning. Switch off PDC. Have the system
checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
System limits
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 ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e.g. a curb, can also disap-
pear from the detection area of the sensors
again before a continuous tone sounds.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Keep the sensors clean and free of ice or
snow in order to ensure that they will con-
tinue 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
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page73.
EBV Electronic brake-force
distribution
EBV controls the brake system's application
pressure in the rear wheels to ensure stable
deceleration.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this
system automatically generates a maximal
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. 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 application. DBC is
deactivated when you release the brake pedal.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. DSC also detects
unstable driving conditions, such as a fishtailing
of the vehicle's rear end or the sliding of the
vehicle on its front wheels. In these circum-
stances, DSC helps keep the vehicle on a safe
path, within physical limits, by reducing engine
output and by applying the brakes in individual
wheels.
The DSC is operational every time you start the
engine.
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
safety margin again by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.

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, resulting in serious personal injury and
property damage.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. portable
phones, in the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
Inside rearview mirror, automatically
dimming*

The inside rearview mirror contains two photo-
cells that control the automatic dimming func-
tion. One is integrated into the mirror glass, the
other is located on the back of the mirror.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers on the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page28, as
otherwise they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor as otherwise dam-
age could result from undesired wiper activa-
tion, refer to page39.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle's
engine, the electrical systems and the trans-
mission may be damaged.<
Use handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise greater clutch
wear will result.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. The best way to brake is to apply
maximum pressure to the brake pedal during
emergency: panic braking. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
