In certain braking situations the perforated
brake rotors can cause operating noises which,
however, have not effect on the performance
and operating safety of the brake system.

Do not drive with your foot resting on the
brake pedal. Even light but consistent

pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.

Driving in wet conditions

When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. 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 full braking efficiency will then be available
when you need it.

Hills

To prevent overheating and the resulting
reduced efficiency of the brake system,

drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.

Sequential Manual Transmission: Do not
drive in idle or with the engine switched

off, otherwise there will be no engine braking
action or support of the braking force and steer-
ing.
Manual transmission: do not drive with the
clutch depressed, in idle or with the engine
switched off, otherwise there will be no engine
braking action or support of the braking force
and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.

Corrosion on brake rotors

When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications 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 minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.

When vehicle is parked

Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.

Before driving into a car wash

Fold in the exterior mirrors, refer to page

otherwise they could be damaged due to the
width of the vehicle.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Ground clearance

Make sure that sufficient ground clear-
ance is available. To drive down curbs,

select the "Sport" program of the EDC Elec-
tronic Damping Control, refer to page

, to

keep the ground clearance as uniform as possi-
ble. Otherwise the vehicle may be damaged.

Cargo loading

To avoid loading the tires beyond their
approved carrying capacity, never over-

load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.
