Have the brake pads checked.
For additional information, refer
to page 92.
Dynamic Brake Control (DBC) l

Malfunction in the DBC system.
The brake system continues to
provide unrestricted conventional
performance.

Dynamic Brake Control (DBC)
warning lamp for Canadian
models
Dynamic Stability Control
(DSC) l
Indicator lamp flashes:
The system is actively regulating engine
torque and braking force.
If the indicator lamp does not go out
after the engine is started, or if it comes
on during normal driving and stays on:
DSC has been switched off or has been
deactivated because of a malfunction.
In the event of a malfunction, have the
system checked by your BMW center.
For additional information, refer to
page 65.
Service Engine Soon l
If the indicator lamp comes on
either continuosly or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.
For additional information, refer to
page 126.

Electronic engine-management
system
Malfunction in the electronic
engine-management system. The elec-
tronics revert to a default mode permit-
ting continued operation, but at lower
than usual engine speeds and with
reduced power. Please have the
system inspected by your BMW center.
Yellow: for your information
Rear fog lamp
Lights up whenever the rear fog
lamp is turned on.

IndexDataTechnologyRepairsCar careControlsOverview
The conceptDSC maintains vehicle stability even in
critical driving situations.
DSC maintains optimal, predictable
response while maximizing traction
when you accelerate from a standing
start or speed up while already
underway. The system recognizes any
tendency for the vehicle to assume an
instable attitude such as oversteer and
understeer, and counteracts this
tendency with a combination of gradu-
ated reductions in engine torque and
braking intervention at individually
selected wheels. DSC provides optimal
stability Ð within the limits defined by
the laws of physics.
The system automatically assumes
operational status each time the engine
is started.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 22.
The indicator lamp flashes:
The system is actively regulating drive
torque and braking force.
The indicator lamp does not go out
after the engine is started, or it comes
on during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the
button. You can continue to drive the
vehicle normally, but without DSC.
Please respond to any suspected
defects by referring the problem to your
BMW center.
To deactivate the systemPress the button, the indicator lamp
comes on and stays on.
When DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following rare circumstances, it
may be effective to deactivate the DSC
for a short period of time:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
To maintain vehicle stability,
always drive with the system
switched on when possible.<520de035
Dynamic Stability Control (DSC)

152n
Dynamic Stability Control (DSC)

Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
When the system detects substantial
differences in rotation rates between
wheels, it acts to inhibit uncontrolled
wheelspin by reducing the drive torque
transmitted to the affected wheel(s),
while also initiating selective braking
intervention as needed.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal
status calculated based on sensor
signals. DSC reacts to deviations from
this ideal status, such as incipient
understeer or oversteer, to restore the
vehicle's stability using a combination
of adjustments to engine torque and
selective braking applications at indi-
vidual wheels. Dangerous skids are
thus prevented before they can even
start, all of this is possible, of course,
only within physically possible limits.You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to the
system.
