Luggage compartment lid Luggage compartment ClosingThe 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.<
Do not drive with the luggage
compartment lid open, since
exhaust fumes could penetrate the inte-
rior of the vehicle. Nevertheless, should
it be absolutely necessary to operate
the vehicle with the luggage compart-
ment lid open (with closed convertible
top):

Antilock Brake System (ABS)The concept ABS helps prevent the wheels from
locking while braking, thereby
enhancing active driving safety. 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.
Under any given road conditions, ABS
can brake the vehicle within the
shortest possible distance and with the
greatest possible driving stability (on
straight-aways and curves, 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 – on all types of road
surfaces (asphalt, concrete, mud, wet
road surfaces, snow, ice).
Braking with ABSThe system is 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 panic
stop – 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 pedal pressure ("panic stop").
Do not let up on the brake pedal even
after it starts pulsating. Since the
vehicle maintains steering response,
you retain the ability to avoid obstacles
using careful steering inputs.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
Pulsation at the brake pedal shows you
that ABS is active and that you are thus
approaching the limits of the brake
system's effective response range. In
addition, a pulsation – a result of the
control function cycles – indicates to
the driver that vehicle speed should be
reduced to adapt to road surface condi-
tions when there is reduced traction and grip between tires and road surface
(slippery road surface).
On road surfaces with a loose surface
layer over a firm base, e.g. on gravel or
snow, as well as when driving with
snow chains on, braking distances may
be longer than with the wheels locked.
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. The consequences of brake
applications with inadequate clear-
ances 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.<

Antilock Brake System (ABS)Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering
feature of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration in
curves, 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 comes
on, refer to page 21. The brake
system will continue to function
the same 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 BMW center
at the earliest opportunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and DSC,
refer to page 21: then the entire
ABS, CBC and DSC
control
system has failed. Continue
driving cautiously and defen-
sively. 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.

Disc brakesDisc brakes furnish optimum decelera-
tion and braking control with greater
fade resistance under heavy use.
Using your vehicle only occasionally,
leaving your vehicle parked for
extended periods, and making only
minimal demands on your brakes
promotes brake disc corrosion and
brake pad contamination, because the
minimal loads required for your disc
brakes to self-clean have not been
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 that BMW has
approved for your particular 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.<
Driving notes When driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles.
Be aware of 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 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
should ever fail, pump the brakes if
possible (refer to page 111).
Drive down long or steep descents in
the mountains using a gear that
requires the least amount of braking.
Doing this prevents putting excessive
loads on the brakes, which in turn
keeps the brake system from possibly
being damaged. Stay within the allow-
able engine speed range. For further
information, refer to page 73.
Braking effect on the engine can be
further increased by downshifting, into
first gear, if necessary. Should the braking effect from the
engine prove inadequate, you should
still avoid extended, continuous
braking. Instead, decelerate the vehicle
by stepping hard on the brake pedal
(while watching out for drivers behind
you), and, if necessary, continue to
decelerate by pumping the brakes
(staggered braking). This staggered
braking technique allows the brakes to
cool in the intervals between active
braking phases. This prevents over-
heating and ensures that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed, with the shift lever in
neutral or with the engine shut off. The
engine does not provide any braking
effect with the transmission in neutral or
with the engine shut off.
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.<

Winter operationBrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface;
the resulting increase in braking
distance is considerable and should
always be kept in mind.
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.
Pumping the brakes will reduce braking
distance while helping you maintain
steering control over the vehicle.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal. Do not downshift to decelerate on
slick road surfaces. Doing so
could cause loss of traction at the rear
wheels, 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. Countersteer care-
fully and attempt to regain control of the
vehicle.
ParkingEngage either 1st gear or reverse.
Apply the parking brake whenever you
park 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.<
