PDC Park Distance Control*
The concept
PDC provides extra safety and convenience
during parking maneuvers. Signal tones indi-
cate the current distance to an object behind or
in front of your vehicle. Four ultrasonic sensors
in both the bumpers monitor the distance to the
nearest object.
The front and rear sensors on the corners have
a range of approx. 2 ft/60 cm. The two rear mid-
dle sensors have a range of approx. 5 ft/1.50 m
and the two front middle sensors of approx.
2.6 ft/80 cm.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching objects too fast, otherwise
the system may give warning of physical obsta-
cles too late.<
If you tow a trailer, the rear sensors cannot take
any practical measurements. Therefore, they
do not switch on.
Automatic mode
In ignition key position 2, the system is auto-
matically activated after approx. one second
each time you shift into reverse or move the
selector-lever into position R. Wait for this short
time span before moving. The system switches
off when you shift out of reverse.
You can have a signal tone programmed
into the system to verify that the PDC is
active.<
Manual mode
In ignition key position 2, press the button; the
indicator lamp lights up.
Deactivating manual mode
Press the button again; the indicator lamp goes
out.
After driving a distance of more than approx.
160 ft/50 m or exceeding a speed of approx.
20 mph/30 km/h, the system switches off and
the indicator lamp goes out. You can reactivate
the system manually as needed.
Signal tones
The distance to an object behind the vehicle is
signaled, in accordance with the position, by an
intermittent tone from a speaker in the rear.
The distance to an object in front of the vehicle
is signaled by an intermittent tone from a loud-
speaker beneath the instrument cluster.
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. The signal tone becomes con-
tinuous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The signal tone is canceled after approx. 3 sec-
onds when the distance to an object remains
constant during this time, if you are moving par-
allel to a wall, for instance.

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.

Technology for comfort, convenience and safety
48
Switching off DSC
Press the button; the indicator lamp in the
instrument cluster lights up continuously.
DSC is now deactivated.
Stabilizing interventions of the chassis control
system DSC are no longer available. However,
the braking interventions that simulate the
function of the differential lock continue to be
active.
In the following exceptional circumstances, it
may be useful to switch off DSC for a short
period:
>When rocking the vehicle and starting off in
deep snow or on loose road surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels spin on muddy surfaces
>When driving with snow chains
As a result of the braking interventions,
the brakes may be subjected to additional
loads when the system is switched off. In order
to limit the brake temperature, brief automatic
suppression of the brake activation is possible.
To maintain vehicle stability, always drive with
the system switched on when possible.<
Reactivating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out. DSC is now acti-
vated.
xDrive
xDrive is the all-wheel drive system of your X3.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The all-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control
The concept
HDC is a system for hill descent assistance that
reduces the speed on steep downward inclines
and makes it even easier to control the driving
characteristics of your BMW under these condi-
tions. The vehicle moves at slightly more than
walking speed without active intervention from
the driver.
HDC is available for activation at vehicle speeds
below approx. 20 mph/35 km/h. When driving
down steep hills with a speed below approx.
20 mph/35 km/h, the vehicle reduces speed
automatically down to slightly more than walk-
ing speed, approx. 5 mph/8 km/h, and then
maintains this speed at a constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the +/– buttons of the cruise
control on the steering wheel.

Activating system
Press the button; the indicator lamp comes on.
The indicator lamp flashes when the brakes are
applied automatically.
Deactivating system
Press the button again; the indicator lamp goes
out.
HDC is deactivated immediately above approx.
35 mph/60 km/h and after approx. 10 seconds
when the ignition is switched off.
Using HDC
In vehicles with manual transmission:
Use HDC in first gear and in reverse gear, as in
the higher gears the engine's braking action
diminishes.
On vehicles with automatic transmission:
You can use HDC in every drive position.
Malfunction
If the indicator lamp in the button goes out in the
HDC mode or fails to light up when the button is
pressed:
HDC is temporarily not available, as the brake
temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
DBC Dynamic Brake Control is defec-
tive. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.If one of the malfunctions described
below occurs, proceed cautiously and
defensively. When driving on poor roads, avoid
using the full throttle or kick-down positions of
the accelerator as well as heavy and panic brak-
ing. Otherwise the drive train may be damaged
or accidents can occur.<
The red brake warning lamp lights up
together with the warning lamps for
ABS and DSC/xDrive. In addition, a
warning signal sounds. ABS, DSC,
HDC and xDrive have failed. Drive may
then only be carried out via the rear
axle. If the brake warning lamp lights up
yellow in the described combination,
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.

Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
