ABS
Disc brakes

Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
Dynamic Brake Control (DBC)*
Driving notes
DBC is included in the DSC, refer to
information beginning on page 74.

heavy rain, it is advisable to apply light
pressure to the brake pedal every few

because the minimal pressure which
must be exerted by the pads to clean
the rotors by brake applications is not
reached.
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
described on page 106.
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.
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.
In the event of a malfunction,
the brake warning lamp lights up
yellow. Normal braking effi-
ciency is still fully available.
Have the system checked and
repaired at your BMW center as
soon as possible.
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
For your own safety: use only

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 in the event of their use.<
impairment of the braking effect.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting into first gear, if
necessary. You can also downshift into
first gear if you are using the manual
mode in a vehicle with automatic trans-
mission, refer to page 63.
Please observe the section "Infor-
mation for your safety" concerning
the ABS system, which also applies to
the DSC system.<
