108Special operating instructions
Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following suggestions.
Because of its engineering design,
the BMW M3 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.
speeds, but do not exceed an engine
speed of 5,500 rpm or a road speed of
105 mph / 170 km/h.
Obey your local and state maximum
speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Vehicles with SMG Drivelogic, refer to
page 69: do not use Drivelogic pro-
grams 5 or 6 or launch control 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.
TransmissionThe transmission will begin to function
optimally after approx.
300 miles/500 km. Shift gears cau-
tiously during this period and do not
exceed an engine speed of 5,500 rpm.
Vehicles with SMG Drivelogic, refer to
page 69: do not use Drivelogic pro-
grams 5 or 6 or launch control during
the break-in period.TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles/300 km.
Obey your local and state maximum
speed limits.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 long service life later on.To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill, e.g. at a
traffic signal, provided that traffic condi-
tions permit to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
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.<
ClutchThe clutch will also begin to function
optimally after about 300 miles/500 km.
Drive cautiously during this break-in
period and do not press the clutch or
shift at high engine speeds.After replacing partsFollow the same break-in procedures if
any of the components mentioned
above have to be replaced in the future.

General driving notesHot exhaust system
High temperatures occur with
every vehicle equipped with a cat-
alytic converter. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle and parking the vehicle,
take care to avoid contact between the
hot exhaust system and flammable
materials, e.g. hay, leaves, grass, etc.
Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
When the vehicle is parkedCondensation forms in the automatic
climate control system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.Before driving through a car washFold in the exterior mirrors manually
because they could otherwise be dam-
aged due to the width of the vehicle.
Hydroplaning
When driving on wet or slushy
roads, reduce road speed. If you
do not, a wedge of water can form
between tire and road surface. This
phenomenon is referred to as hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness.<
The risk of hydroplaning increases as
the tread depth of the tires decreases,
refer also to Tire tread on page 116.
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed. Other-
wise, the vehicle's engine, the electrical
systems and the transmission may be
damaged.<
Braking safelyYour BMW is equipped with ABS as a
standard feature. If you are in a situa-
tion which requires full braking, it is
best to brake using maximum brake
pressure: panic stop. Since the vehicle
maintains steering responsiveness, you
can avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.
Do not rest your foot on the brake
pedal while driving. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
Wet roads:
If the roads are wet or if there is heavy
rain, it is advisable to gently press the
brakes for a brief moment every few
miles/kilometers. Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat generated in this process helps
dry the pads and rotors. Immediate
braking force is then available if neces-
sary.

Inclines:
To prevent overheating and, as a
result, diminished braking effec-
tiveness, drive down long or steep
downhill grades in a gear which
requires the least braking. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
The braking power of the engine can be
further enhanced by downshifting the
automatic transmission in manual
mode, if necessary, into first gear. This
helps avoid placing excessive loads on
the brake system.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine switched off. Oth-
erwise, the engine provides no braking
effect while the transmission is in idling
position, and there is no power-assist
for braking or steering when the engine
is off.
Floor mats, floor carpets or other
objects must not be in the area near the
brake or accelerator pedal, as this
could impair the movement of the ped-
als.<
Corrosion on the brake rotorsLimited vehicle use, extended periods
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 and contamination to accumulate
on the brake pads. This occurs because
the minimal pressure which must be
exerted by the pads to clean the rotors
by brake applications is not reached.
Corrosion on brake rotors is signaled by
a pulsation during initial braking that
usually does not disappear even after
extended subsequent braking.
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.<
Portable phone in the vehicle
BMW advises against using
mobile equipment, e.g. cellular
phones, inside the vehicle without con-
necting them directly to an outside
antenna. Otherwise, it cannot be ruled
out that vehicle electronics and the
mobile equipment interfere with one
another. In addition, it is not ensured
that the radio waves emitted during
transmission are directed outside of the
vehicle interior.<
