Corrosion on brake rotors is signaled by
a running or pulsation during braking;
even extended subsequent braking will
not cure this phenomenon.

It is a good idea to periodically dry the
brakes with a gentle application when
driving in rain and on wet roads. Watch
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 your brake system will
respond with undiminished efficiency
when you need it.

Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions are required. This helps avoid
placing excessive loads on the brake
system. Stay within the allowable rpm
range. For additional information, refer
to page

Do not coast with the clutch
depressed or with the gearshift

lever in idle. Do not coast with the
engine switched off. If you do so the
engine provides no braking effect and
there is no power assist for braking or
steering when the engine is not run-
ning.

Brake pads

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