Malfunction
The warning lamp lights up. A mes-
sage appears on th
e Control Display.
PDC is malfunctioning. Have the
system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page138.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
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 short-
est possible braking distance during full brak-
ing. This system exploi ts all of the benefits
provided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull aw ay from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through brakin g actions at the indi-
vidual wheels.

ControlsTechnology for driving comfort and safety
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident. <
Deactivating DSC
Press the button for at le ast 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster.
Dynamic Traction Control DTC and DSC have
been simultaneously de activated. Stabilizing
and drive-output promoting actions are no
longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed to enhance drive output if the
drive wheels experience a significant loss of
traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; th e indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for part icular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following sp ecial circumstances:
> When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains
Activating DTC
Press the button; the indicator lamp for DSC
OFF lights up and TRACTION is displayed in
the instrument cluster.
For better control
If the indicator lamp flashes: DTC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and TRAC-
TION is displayed in the instrument
cluster: DTC is activated.
Deactivating DTC
Press the button again; th e indicator lamp in the
instrument cluster goes out.

xDrive
xDrive is your BMW's fo
ur-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly fast er than double walking
speed without the driver needing to intervene.
HDC is available for activation at vehicle speeds
below approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or de creasing speed
You can use the accelerato r or brakes to vary
this automatically cont rolled speed within a
range of between approx. 3 mph/5 km/h and
20 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.
1 To increase speed
2 To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically,
the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically de activated at speeds
over approx. 40 mph or 60 km/h.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Integrated universal remote
control
The concept
The Integrated universal remote control can be
used to operate up to 3 functions of remote-
controlled devices such as garage door open-
ers or lighting systems. The Integrated univer-
sal remote control thus replaces as many as
three different hand-held transmitters. To oper-
ate them, the buttons on the interior rearview
mirror must be programmed with the desired
functions. Programming requires the hand-held
transmitter for the respective device.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control to operate a
device, always inspect the immediate area to
make certain that no people, animals or objects
are within the pivoting or travel range of the
device being operated.
Also follow the safety in structions supplied with
the hand-held transmitter. <
For security reasons, ma ke sure to delete the
stored functions before selling the vehicle, refer
to page 122.
Compatibility
If this symbol appears on the package
or in the instructions supplied with the
device to be operated, you can gener-
ally assume that the devi ce is compatible with
the Integrated univer sal remote control.
