Antilock Brake System (ABS)The conceptABS enhances active safety by helping
to prevent the wheels from locking un-
der braking. The reason: 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.
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help retain steering and maneu-
vering capability on all types of road
surface (asphalt, cement, dirt, mois-
ture, snow and ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight-away and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is deacti-
vated whenever the vehicle's speed
drops back below approx. 4 mph
(6 km/h). This means that the wheels
can lock in the final phase of a brake
application Ð a factor of no significance
in actual use.
If you are in a situation which requires
full braking, you will exploit the full ben-
efits of the ABS system if you apply
maximum brake pressure ("panic stop").
Since the vehicle maintains steering re-
sponsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal indicates
to the driver that ABS is active, that is,
that the vehicle is within its maximum
braking range. In addition, the audible
pulsation that accompanies the control
operation calls the attention of the
driver to the reduced traction between
the tires and the road surface (slippery
road surface), and serves as a reminder
that the speed of the car should be re-
duced to adapt to road conditions.On road surfaces which have a loose
layer on a firm base (on gravel or snow,
for instance), the braking distances with
ABS may be longer than with the
wheels locked. The same applies when
snow chains have been mounted. How-
ever, ABS continues to provide en-
hanced vehicle stability and steering re-
sponse under these conditions.

Antilock Brake System (ABS) Disc brakesInformation for your safetyNot even ABS can suspend the laws of
physics. ABS alone cannot prevent
accidents when the brakes are applied
without an adequate safety interval
between vehicles, if the car is driven at
an excessive rate of speed in curves, or
if 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 that could affect
your own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
In the event of a fault
If the ABS warning lamp in the
instrument cluster comes on,
refer to page 23. The brake
system then reverts to conven-
tional operation as on vehicles
without ABS. However, have the
brake system checked by your BMW
center as soon as possible. To prevent
undetected defects and cumulative
faults from adversely affecting the brake
system, refer any problems to your
authorized BMW center at the earliest
opportunity.
Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads during
brake applications to clean the rotors is
not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: Use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Disc brakesDriving notesWhen driving in wet conditions and in
heavy rain, it is a good idea to apply
light pressure to the brake pedal every
few miles (kilometers). Watch traffic
conditions to ensure that this maneuver
does not endanger other road users.
The heat which is generated by the
brake applications helps to dry the
brake pads and rotors.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique de-
scribed below (refer to page 131).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency. Shift down to
a gear in which only minimal periodic
brake applications are required or move
the selector lever to the appropriate
lower range with automatic transmis-
sion.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting as far as 1st gear,
or the 1st or 2nd shift position, on steep
descents.Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate by applying more substantial
pressure to the brake pedal (watch for
following traffic!), then releasing the
pedal, then repeating the application.
This staggered braking technique al-
lows the brakes to cool in the intervals
between active braking phases, pre-
venting overheating and ensuring that
full braking capacity remains available
at all times.
Do not coast with the clutch de-
pressed or with the transmission
or selector lever in neutral. Do not coast
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in neutral, and there is no power-as-
sist for braking or steering when the
engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Dynamic Brake Control (DBC)
*
If you apply the brakes rapidly, this sys-
tem automatically produces the maxi-
mum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction, the yellow
warning lamp comes on. Conventional
braking efficiency is available without
limitations.
Have the system checked and repaired
at your BMW center as soon as possi-
ble.
For "Information for your safety"
covering the ABS system, refer to
page 128. This information also gener-
ally applies for DBC.<

Winter operationRubber seals and components In order to prevent the weather-strip-
ping from freezing, apply BMW rubber
treatment or silicone spray to the seals
on the doors, hood and luggage com-
partment lid/tailgate.
A full range of car-care products is
available from your BMW center.< Snow chainsBMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
For maximum traction, we recommend
that you manually deactivate the
ASC+T/DSC
* when driving with snow
chains mounted. Refer to page 91.
Starting offWe recommend that you use the man-
ual control switch to deactivate ASC+T/
DSC
* when starting off in deep snow or
when rocking the car to free it (refer to
page 91).
Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Adapt
your speed and driving style when ap-
proaching grades or slopes. Maintain
an adequate distance between yourself
and the car ahead.BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking dis-
tance are considerable and should be
kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response. If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake
pedal until the wheels just start to roll
again while still maintaining enough
force to continue braking.
Following that, increase pedal pressure
again. Reduce the pressure as the
wheels lock, then reapply pressure.
Repeat this procedure. This type of
staggered braking will reduce the brak-
ing distance, and the vehicle still re-
mains responsive to steering.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.
Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces which
provide only poor or uneven traction.<
