Safe braking
Emergency stops
You brake most effectively when you
apply maximum pedal pressure in situa-
tions requiring it: emergency stops.
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum of steering effort.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.
Brake fluid level
If the brake fluid level is too low and
brake pedal travel has become longer,
there may be a malfunction in one of
the two brake system's hydraulic cir-
cuits.
Proceed to the nearest BMW
Sports Activity Vehicle center.
In so doing, increased pressure on the
brake pedal may be required, and slight
pulling to the side and longer braking
distances may result. Please remember
to adapt your driving style accord-
ingly.

Disk 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
that the pads must exert to clean the
rotors during brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that 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 brak-
ing force is then immediately available
when required.
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 braking action.
Do not drive with the clutch pedal
depressed, at idle or with the
engine switched off, as otherwise there
will be no engine braking effect or
power assistance for braking and steer-
ing.
BMW recommends having brake
inspections performed at a BMW
Sports Activity Vehicle center only. If
you do not, parts of the 4-wheel drive
system could be damaged.
No floor mats, carpets or other objects
may lie in the area of pedal travel, as
otherwise pedal operation may be
impaired.

Brake pads
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.
