The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance between your front and
rear bumpers and the nearest object.
To do this, four ultrasonic sensors in
the front and rear bumpers each mea-
sure the distance to the nearest object.
The monitoring range of the front sen-
sors and two rear sensors at the ends
of the rear bumper extends outward
roughly 2 ft (60 cm), while the rear
bumper's two centrally located sensors
detect objects at distances of up to
approx. 5 ft (1.50 meters).Automatic functionThe system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the "R" position with the igni-
tion key in position 2.
Manual activationPress the button, the indicator lamp
lights up.
When you subsequently drive a dis-
tance of more than approx. 160 ft
(50 meters) or exceed a speed of
approx. 20 mph (30 km/h), the system
switches off and the indicator lamp
goes out. Reactivate the system as
required.390us727
Acoustic signalsThe distance from an obstacle is indi-
cated in front with a higher intermittent
tone, at the rear with a lower intermit-
tent tone. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous tone indicates the
presence of an object less than 1 ft
(30 cm) away.
The warning signal is canceled after
approx. three seconds if you are
moving parallel to a wall.
If there is a malfunction of the system:
The indicator lamp flashes and a brief
continuous signal tone is heard
>if you activate PDC with the button
>when you first select reverse or move
the selector lever into the "R" posi-
tion after switching on the ignition
>if a malfunction occurs while the PDC
system is active.
Switch the system off and have the
cause of the malfunction corrected at
your BMW center.

ASC+T/DSC
*
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 21.
Indicator lamp flashes:
The system is active and governs drive
torque and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving:
There is a system malfunction or the
system was deactivated with the
button. You can still drive the vehicle
normally without ASC+T/DSC.
Please consult your BMW center for
repairs.
To deactivate the systemPress the button, the indicator lamp
lights up and remains on continuously.
Depending on equipment options, the
button is marked with ASC or DSC.
With deactivated ASC+T/DSC you are
driving with conventional, unregulated
torque transfer.
In the following exceptional situations,
it may be effective to deactivate the
ASC+T/DSC for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.390us728
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T/DSC.
An appropriate driving style always
remains the responsibility of the driver.
Do not use the extra safety margins fur-
nished by these systems as an excuse
for taking unnecessary risks.< Dynamic Brake Control (DBC)
*
DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Parking lamps (side marker
lamps)
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
For lighting on one side for parking as
an additional feature, refer to page 104.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps (side marker lamps)
remain on.
390de732
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhen the driver's door is opened with
the ignition key in position 0 an acoustic
signal will sound for several seconds to
remind you that you have forgotten to
switch off the lamps
.
Vehicles with alphanumeric Check
Control
*:
The reminder is provided by the Check
Control, refer to page 87.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving in
ignition key position 2.
Automatic headlamp control
*
When the switch is set to this
position the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light ( in tunnels, at dusk, etc.)
as well as rain and snow.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lamps should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlamps on manu-
ally.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

The green indicator lamp in the
instrument cluster lights up to
indicate that the front fog lamps
are on.
If the high beams are switched on, the

If the automatic headlamp control
is on, the low beams will come on
automatically whenever you activate
the fog lamps.<
