Dynamic Stability Control (DSC) The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for example)
and holds the vehicle on a sure course
by intervening via the engine and by
braking intervention at the individual
wheels.
The system activates automatically each
time you start the engine.462us284
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or comes on dur-
ing the course of normal vehicle opera-
tion:
If the system was not switched off,
there is a system malfunction. The vehi-
cle remains operational, but without
DSC. Please consult your BMW center
for repairs.
To deactivate the systemPress the button. The indicator lamp
flashes.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In exceptional instances, it is effective
to deactivate the system:
>when rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 110.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 163.

Changing a wheel9 Position the new wheel or the
space-saver spare tire
* on the hub
and screw at least two lug bolts fin-
ger-tight into opposite bolt holes.
10 Screw in the remaining lug bolts.
Tighten all the bolts securely.
11 Lower the jack and remove it from
beneath the car.
12 Tighten the lug bolts in a diagonal
pattern.

13 Wheels with full wheel covers:
Position the wheel cover with the
valve opening over the valve (arrow)
and press it onto the wheel with
both hands.
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with RDC (Tire Pres-
sure Control)
*:
Reactivate the system after mount-
ing either the spare tire or after in-
flating tire(s) to proper pressure.
Refer to page 80.
Use only the full wheel cover in-
stalled by the factory. Other wheel
covers may not fit securely. The full
wheel cover may not be installed on the
space-saver spare tire
* since this could
damage the cover.<
460de125
The vehicle jack is designed for
changing wheels only. Do not at-
tempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
Have the lug bolts checked for proper
tightness with a calibrated torque
wrench at the earliest possibility [torque
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, be sure that
you do not damage the retaining pin in
the spare tire recess.
If light-alloy wheels other than Original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as quickly as
possible and have the new wheel bal-
anced.

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer ade-
quate, the gas generators of the driver
and passenger-front airbags are ignited.
However, the passenger-side airbag is
only triggered if an additional sensor
has recognized that the passenger seat
is occupied.
In the event of a side collision, the Head
Protection and side airbags in the front
or rear
* are triggered if necessary.
390de319
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the smoke associated
with it dissipates.
The entire process is completed within
fractions of a second.Highly sensitive sensors monitor the
number of revolutions of the wheels.
When equipped with DSC, they also
monitor steering angle, lateral accelera-
tion, brake pressure and the movement
of the vehicle around its vertical axis.
If differences in the wheel speeds occur,
the system counteracts the danger of
wheelspin by reducing engine torque.
If necessary, the system also responds
with additional application of the brakes
at the rear wheels.
If the system detects an instability in the
vehicle's condition, the braking action
can also be directed to the front wheels
by the DSC in order to help stabilize the
vehicle.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and driving stability.
The braking intervention may be ac-
companied by sounds specific to the
system.
