Disc brakes
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 to
form on rotors, while contaminants
accumulate on the brake pads. This
occurs because the minimal pressure
which must be exerted by the pads dur-
ing 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.

When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal from time
to time. Monitor traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
generated in this process helps dry the
pads and rotors to ensure that The
braking force is then immediately avail-
able when required.

of the braking effect.
Do not coast with the clutch
depressed or with the transmis-
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine switched off. The
engine then provides no braking effect,
and there is no power-assist for braking
or steering.
BMW recommends having brake
inspections performed at a BMW
Sports Activity Vehicle center only.
If you do not, parts of the four-wheel
drive system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.

For your own safety: use only
brake pads that BMW has

they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.
