Antilock Brake System (ABS)

l

ABS has been deactivated in
response to system malfunction.
Conventional braking performance
remains available with no loss of effi-
ciency. Please have the system
inspected at your BMW center.
For additional information refer to
page 109
ABS warning lamp for Canadian
models.
Engine oil level
Comes on during driving: the
engine oil level has fallen to the
absolute minimum; refill as soon as
possible. Do not drive more than
approx. 30 miles (50 km) until you do.
For additional information refer to
page 121
Engine oil level
Comes on after the engine has
been switched off: add engine
oil at the earliest opportunity (next time
you stop to refuel).

Automatic Stability Control plus Traction (ASC+T)

The conceptThis system optimizes vehicle stability
and traction, especially when you are
starting off, accelerating or when going
through curves.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes to the rear wheels.
ASC+T is ready each time you start the
engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to pages 18, 19.
The indicator lamp flashes:
ASC+T is actively controlling drive
torque and braking intervention.
The indicator lamp fails to 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. Consequently, interventions to
increase driving stability (as described
in the preceding column) are no longer
available. You can still drive the vehicle
perfectly well without ASC+T
In the event of a fault, please contact
your BMW center, refer to
pages 18, 19.
Switch off the ASC+TPress the button; the indicator lamp
comes on and stays on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
be effective to deactivate the ASC+T
for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the ASC+T acti-
vated whenever possible.<

ASC+T Dynamic Stability Control (DSC)
*
Switch the ASC+T back onPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.<
The conceptThe Dynamic Stability Control (DSC)
maintains vehicle stability, even in crit-
ical 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, as far as is
possible within the laws of physics,
helps keeping the vehicle on a steady
course by reducing the engine speed
and brake applications to the individual
wheels.
DSC is operational every time you start
the engine. DSC incorporates the func-
tionality of the Automatic Differential
Brake (ADB) and the Cornering Brake
Control (CBC).
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 in standby mode when DSC
is deactivated.
Indicator lamp
The indicator lamp in 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 is actively controlling drive torque
and braking intervention.
The indicator lamp stays lit:
DSC has been deactivated manually;
ADB is operational.
ADB control intervention is not indi-
cated.
The indicator lamp and the
brake warning lamps will remain
on continuously:
The DSC, ADB and DBC have
been deactivated 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.

Dynamic Stability Control (DSC)
*
To switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; ADB is operational.
In the following rare situations, it may
prove useful to deactivate the ADB for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.
Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.
To switch DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamps light up
and remain on continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible. lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
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.

Changing a wheel8. Remove accumulations of mud and
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
9. Position the new wheel or the
space saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10. Screw in the remaining lug bolts
and screw in all the bolts in a diag-
onal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts securely in a
diagonal pattern
13. Wheels with full wheel covers
*:
Place the wheel cover with the
valve opening (arrow) over the
valve. Use both hands to press the
cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(RDC)/Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reactivate the system, refer to
page 83 or 85.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 72 lb ft (72 100 Nm] at the
earliest opportunity.<
When storing a wheel in the spare tire
recess take care to avoid bending the
threaded rod.
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 soon as
possible and have the new wheel/tire
balanced.
