Disk brakes
Disk 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
disks 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
disks by brake applications is not
reached.
If the brake disks 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 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.

Driving notes
While driving on wet roads or in heavy
rain, it is a good idea to apply light
pressure to the brake pedal every few
miles or kilometers. Watch traffic condi-
tions 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 disks.
Maximum braking force is obtained
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 should ever fail, pump
the brakes if possible (refer to
page
109 ).
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. Stay
within the allowable engine speed
range. For further information, refer to
page
69 .
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary.
Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate the vehicle by applying more
substantial force on the pedal (watch
for following traffic). Pause before
repeating the brake application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring 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.
