Catalytic converter Antilock Brake System (ABS)
Be sure to observe the instruc-
tions above to prevent unburned
fuel from reaching the catalytic
converter, otherwise, the catalytic
converter could overheat and be
damaged.
High temperatures occur in any vehicle
equipped with a catalytic converter.
Heat shields are installed adjacent to
some sections of the exhaust system.
Never remove these shields; do not
apply undercoating to their surfaces.
When driving, standing at idle, and
parking the vehicle, take care to avoid
contact between the exhaust system
and flammable materials (grass, hay,
leaves etc.). Such contact could lead to
a fire, resulting in personal injury and
property damage.<
The concept ABS enhances active driving safety by
helping to prevent the wheels from
locking under braking. The reason:
locked wheels are dangerous. When the
front wheels slide, the driver loses
steering control over the vehicle. Trac-
tion loss at the rear wheels can cause
the rear end to break into an uncon-
trolled 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.
>Assured ability to steer and
maneuver Ð on the various road
surfaces (asphalt, concrete, dirt,
wet conditions, snow, ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight-away and in
curves, on asphalt, ice, wet road
surfaces, etc.).
Braking with ABSThe system is operative once the
vehicle exceeds a speed of approx.
6 mph (10 km/h). It is deactivated once
again below approx. 4 mph (6 km/h).
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 closed-loop control circuit
cycles in fractions of a second. A pulsa-
tion 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.

Antilock Brake System (ABS)Nevertheless, ABS possesses the
advantage of vehicle stability and
steering response.Information for your safetyNot even ABS can suspend the laws
of physics. The consequences of brake
applications with inadequate clea-
rances for safety between vehicles,
excessive speed or if aquaplaning
occurs are always the responsibility 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 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. Cornering Brake Control (CBC) CBC is an advanced engineering devel-
opment of ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.
In the event of a malfunction
If the ABS warning lamp in the
instrument cluster lights up,
refer to page 22. The brake
system then reverts to conventional
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.
ABS warning lamp for Canadian
model.
If the brake warning lamps light
up together with the indicator
lamps for ABS and ASC+T/DSC
Ð refer to page 19 Ð then the
entire regulating system, the
ABS, CBC and ASC+T/DSC
and
ADB/ ADB-X/DBC have failed.
Continue driving cautiously and
defensively. Avoid full brake applica-
tions. This could cause the vehicle to
lose stability and you might no longer
be able to control it.
Have the system checked by your BMW
center as soon as possible.

Antilock Brake System (ABS) Disc brakesDynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 81.
If you step on the brake rapidly, this
system automatically produces
maximum 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. Normal braking efficiency
and the anti-lock braking system are
still fully available.
Have the system checked and repaired
at your BMW center as soon as
possible.
Refer to the "Information for your
safety" covering the ABS system.
This information also generally applies
for DBC.<
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
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads which 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.<

IndexDataTechnologyRepairsCar careControlsOverview
Disc brakesDriving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Watch traffic conditions
to ensure that this maneuver does not
endanger other drivers. The heat which
is generated by the brake applications
helps to dry the brake pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique (refer to page 122).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect.
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary. In the manual
mode of the automatic transmission,
you can also downshift into first gear.
Refer to page 66.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic),
releasing the pedal, and then repeating
the application (staggered braking). The
cooling phases between active braking
intervals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not allow the vehicle to coast
when the clutch is depressed or
by shifting into neutral while moving. Do
not drive when the engine is switched
off. The engine provides no braking
control when the clutch is depressed or
the transmission is in "Neutral" and
there is no power-assist for the brakes
when the engine is shut off.
BMW 325xi: have brake inspections
performed at a BMW center only. If you
do not, parts of the four-wheel drive
system could be damaged.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<

122n
Winter operationBrakingWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
Keep this in mind, because the braking
distance increases substantially.
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.
Then increase the pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
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 Ð if you want to decel-
erate. 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 that
provide only poor or uneven traction.<
Skid control Depress the clutch and release the
accelerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage 1st or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
"Park." On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not come
on when the parking brake is
applied.<
