Parking brake To engageThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.
The lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument panel comes on when
the ignition key is in position 2. Refer to
page 21.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.460us024
If, in exceptional circumstances,
it should be necessary to engage
the parking brake while the vehicle is
in motion, do not pull the lever with
excessive pressure. Keep your thumb
pressed against the release button
while carefully pulling the lever up to
apply moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle. The brake lamps do not
come on when the parking brake is
applied.
Vehicles with manual transmission:
Always apply the parking brake when
parking on slopes and inclined
surfaces, since placing the shift lever in
1st gear or reverse may not provide
adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.

ASC+T
The conceptThis system enhances driving stability
and traction, especially when you are
just starting off, accelerating or in
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 available as soon as the
engine starts up.
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:
ASC+T controls the drive forces.
If the indicator lamp fails to go out after
the engine is started, or if 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 not avail-
able. However, you can still drive the
vehicle as usual, but without ASC+T.
Please consult your BMW center in the
event of a malfunction, refer to
pages 21 and 22.
Deactivating the ASC+T Press the button; the indicator lamp
comes on and stays on.
The illustration shows 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.
Refer also to page 119.
To maintain vehicle stability,
always drive with the ASC+T
activated whenever possible.<462de292

ASC+T 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. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.<
For additional details concerning
ASC+T, please refer to the chapter
"Advanced Technology" on page 175.
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
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the car on a steady
course by reducing the engine spped
and brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB and CBC, refer to
page 116.
The ADB (automatic differential braking)
copies the function of conventional
differential and transverse lock through
brake intervention, and increases trac-
tion whenever conditions merit, e. g.
when driving on snow-covered roads.
If the DSC is switched off the ADB will
still be in ready mode.
Indicator lamp
The indicator lamp on the instru-
ment panel will go out shortly
after the ignition has been
started. Refer to pages 21 and 22.
If the indicator lamp flashes:
ASC+T or DSC control the drive and
braking forces.
The indicator lamp stays lit:
DSC has been switched off via the
button; ADB is operational.
ADB intervention not indicated.
The indicator lamp and the
brake warning lamp will light up
continously:
The DSC, ADB and DBC have
been turned off with the switch
or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center. Refer to pages 21 and 22.
Indicator and warning lamps for
Canadian models.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following recommendations.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine and road
speeds, but do not exceed 4,500 rpm
or a speed of 100 mph (160 km/h):
Obey your local and state maximum
speed limits.
Do not apply full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles
(2,000 km), engine speed and vehicle
speed can be gradually increased.
Follow the same break-in procedure if
either the engine or the differential is
replaced in the future.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
For this reason drive cautiously during
the initial 200 miles (300 km).
Obey your local and state maximum
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.<
Brake systemApproximately 300 miles (500 km) must
elapse before the brake pads and discs
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and long 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.
(500 km). Engage the gears carefully
during the break-in period.

Antilock Brake System (ABS)The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. This is because locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
The system can achieve the shortest
braking distances possible under most
conditions (on straight-aways and in
curves, on asphalt, ice, wet road
surfaces, etc.).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help maintain steering control and
maneuverability Ð on all types of road
surfaces (asphalt, concrete, mud, on
wet road surfaces, snow, ice).
Braking with ABSAt approx. 6 mph (10 km/h), the system
becomes operative. Whenever the
vehicle's speed drops below approx.
4 mph (6 km/h), the ABS is deactivated.
This means that the wheels can lock in
the final phase of a panic stop Ð a factor
of no significance in actual use.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum brake pressure ("panic
stop"). Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you
should adapt road speed to the road
conditions.On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel or snow, for
example), or when snow chains are
mounted, braking distances may be
longer than with locked wheels.
However, ABS continues to provide
enhanced vehicle stability and steering
response under these conditions.
Information for your safetyNot even ABS can suspend the laws of
physics. ABS cannot prevent the
consequences of brake applications
with inadequate clearances for safety
between vehicles, when exceeding the
speed limit, or the risks involved when
aquaplaning occurs. Responsibility for
these types of situations remains in the
hands (and at the feet) of the driver. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking
increased risks.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
