Luggage compartment lid/TailgateClosing Ð sport wagonYou can pull the tailgate down by plac-
ing both hands in the handle recesses
(arrows).
To close the tailgate, merely press it
down gently. The closing process will
then be carried out automatically.
To avoid injuries, be sure that the
travel path of the tailgate is clear
when it is closed, as with all closing
procedures.< 392de160
When the tailgate of the sport
wagon is opened, the clearance
from the ground to the upper edge is
more than 6.5 feet (two meters). Please
keep this in mind when opening the tail-
gate (in a garage, for example).<
Operate the vehicle only when the
luggage compartment lid/tailgate
is completely closed. Otherwise,
exhaust fumes could penetrate the
interior of the vehicle. Should it be
absolutely necessary to operate the
vehicle with the luggage compartment
lid/tailgate open:
>Close all windows. Shut the sliding/
tilt sunroof
>Increase the airflow of the automatic
climate control to a high level. Refer
to page 101.<

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.<
