Comes on while driving and is
accompanied by an alarm: the
engine oil level has fallen to the abso-

Do not drive more than 30 miles/50 km
before refilling.

112Special operating instructions
Break-in proceduresTo ensure that your vehicle continues to
provide maximum economy throughout
an extended service life, we request
that you devote careful attention to the
following instructions.
Because of its engineering design,
the BMW M3 Convertible is an
especially high-quality vehicle. It is in
your best interest to follow the break-in
tips very closely. Doing this, you will
create the basis for a long, optimum
service life.The first 1,250 miles/2,000 km: drive
at varying engine and road speeds,
but do not exceed the following
engine or road speeds:
5,500 rpm or 105 mph / 170 km/h.
Always obey all official speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Vehicles with SMG Drivelogic, refer to
page 70: refrain from using driving pro-
gram 6 in the sequential mode during
the break-in period.
>Following the break-in inspection at
1,250 miles/2,000 km, you can grad-
ually increase engine or road speeds.
Please remember to observe the same
break-in procedures if either the engine
or the differential should have to be
replaced later in the course of the vehi-
cle's service life.TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
We thus ask you to drive with extra care
during the first 200 miles/300 km.
Always obey all official speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as hydroplaning, and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
Brake systemApprox. 300 miles/500 km must elapse
before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and an extended service life
later on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill – at a traf-
fic signal, for instance; use caution to
avoid posing a danger to other road
users.
You can prevent corrosion in the drums
by periodically repeating this proce-
dure.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off – when tow-
ing, for example – substantially higher
levels of pedal force will be required to
brake the vehicle.<

114
Antilock Brake System (ABS)The conceptABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of ABS system if you apply maximum
pedal pressure – panic stop. Since the
vehicle maintains steering responsive-
ness, you can avoid possible obstacles
with a minimum of steering effort,
despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 86.
If you apply the brakes rapidly, this sys-
tem automatically generates maximum
braking force boost and thus helps to
achieve the shortest possible braking
distance in panic braking situations. All
of the benefits of the ABS are exploited
under these circumstances.Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
Cornering Brake Control (CBC)CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.
Brake systemBrake fluid levelLow brake fluid level in the reservoir
combined with longer than usual pedal
travel may indicate a defect in one of
the brake system's hydraulic circuits.
Proceed to the nearest autho-
rized BMW center. Higher brake
application pressure may be necessary
when stopping, and the vehicle may
exhibit a slight tendency to pull to one
side. Brake distances may even be
longer. Please remember to adapt your
driving style accordingly. with the vehicle parked or in storage,
and operating conditions in which brak-
ing is restricted to gentle, low-pressure
applications will all increase the ten-
dency for corrosion to form on the
rotors; this is often accompanied by a
simultaneous accumulation of contami-
nation on the brake pads. The pads
must exert a certain minimal level of
pressure against the rotors for the disc
brakes' inherent self-cleaning effect to
remain effective.

115
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads it is useful to apply light pressure
to the brake pedal every few miles.
Monitor traffic conditions to ensure that
this maneuver does not pose a hazard
to you or to other road users. The heat
generated in this process helps dry the
pads and rotors to ensure that your
brake system will respond with undi-
minished 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. By minimizing the
loads placed on the brake system, this
strategy helps ensure that optimal
brake system response will remain
available at all times. Stay within the
allowable rpm range. For additional
information, refer to page 79.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 that BMW has
released for your particular 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.<
Hardtop*It is not necessary to remove the fabric
top even in the winter, when the hard-
top is generally in constant use. But you
can also remove it easily at any time.
Before the fabric top is stored in the
convertible top compartment, it must
be absolutely dry in order to avoid
water spots and mildew from forming.
The hardtop offers reading lamps and
clothes hooks that can be used just by
pressing. It is also possible to mount a
luggage rack on the roof. Please con-
sult your BMW center.
When hanging clothing from the
hooks, be sure that they will not
obstruct the driver's vision. Do not hang
heavy objects on the hooks. If you do
so, they could cause personal injury
during braking or evasive maneuvers.<
Two people are required for installation
or removal. Work with extreme caution
in order to avoid paint damage and
damage to the body or hardtop.
To facilitate hardtop installation or
removal, you can obtain a specially
designed hardtop lift* or hardtop rack*
at your BMW center.
