ASC+T Dynamic Stability Control (DSC)
*
Reactivating the ASC+TPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.<
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, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, within
physically feasible limits, helps keeping
the vehicle on a steady course by
reducing the engine speed and brake
applications to the individual wheels.
The DSC is operational every time you
start the engine. DSC incorporates the
ADB and CBC (Cornering Brake
Control) functions.
The Automatic Differential Brake (ADB)
relies on selective braking applications
at the drive wheels to furnish the func-
tionality of a conventional limited-slip
differential for enhanced traction in crit-
ical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
The ADB is operational when DSC is
switched off.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off with the
button; ADB is operational.
ADB control intervention is not indi-
cated.
The indicator and the brake
warning lamps will remain on
continuously:
The DSC, ADB and DBC have
been switched off with the
button or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center, refer to pages 18, 19.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following information.
Engine and differentialUp to 1,200 miles (2,000 km):
Constantly vary both engine and vehicle
speed, remembering not to exceed
4,500 rpm or 100 mph (160 km/h)
during this period.
Always obey all official speed limits.
Do not use full throttle, and avoid
pressing the accelerator beyond the
kickdown point during these initial
miles.
You can then proceed to increase both
engine and vehicle speed once the
initial 1,200 miles (2,000 km) have
elapsed.
You should also observe the same
break-in procedures if the engine or
differential is replaced later in the
course of the vehicle's life.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
after an initial break-in period. We thus
ask you to drive with extra care during
the first 200 miles (300 km).
Always obey all official speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads. elapse before the brake pads and
rotors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and an extended service
life later on.
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off Ð when
towing, for example Ð substantially
higher levels of pedal force will be
required to brake the vehicle. elapse before the clutch starts to
operate at optimum efficiency.
Remember to engage the clutch care-
fully during this initial period.
Break-in procedures

OverviewControlsMaintenanceRepairsDataIndex
Engine oilChecking oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
Adding engine oilWhile you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never
allow the oil level to fall below this
mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
at your BMW center.
