*
If the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.460de011
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<460de067
Do not drive with the luggage
compartment lid open, since
exhaust fumes could penetrate the inte-
rior of the vehicle. Should it be abso-
lutely necessary to operate the vehicle
with the luggage compartment lid open:
>Close all windows and the sliding/tilt
sunroof.
>Increase the air supply for the air
conditioner or the automatic climate
control to a high level. Refer to
page 92 or 98.<

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic convertor. If you do not, the cata-
lytic converter could respond by
overheating, leading to serious
damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle, and parking the
vehicle, take extra care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves,
etc.). Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
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, wet
road surfaces, snow, ice).Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). Below approx. 4 mph
(6 km/h), it is once again 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 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, 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

119n

Antilock Brake System (ABS)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 mislead you into taking
increased risks.
Do not make any modifications to
the ABS system. Service proce-
dures 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 during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.In the event of a fault
If the ABS 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 cumu-
lative faults from adversely affecting the
brake system, refer any problems to
your BMW center at the earliest oppor-
tunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and
ASC+T/DSC, refer to page 21,
the entire ABS, CBC and
ASC+T/DSC control system has
failed. Continue driving
cautiously and defensively.
Avoid full brake applications. This could
cause the vehicle to lose stability and
you might no longer be able to control
it.
Have the system checked as soon as
possible by your BMW center.

and
ADB/ADB-X/DBC indicator and
warning lamps for Canadian
models.
Dynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 84.
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 brake warning lamp
comes on. Normal braking effi-
ciency and ABS are still fully available.
Have the system checked and repaired
at your BMW center as soon as
possible.
Please observe the section "Infor-
mation for your safety" concerning
the ABS system, which also applies to
the DSC system.<
