Stowing cargo>Load heavy cargo as far forward as
possible – directly behind the back-
rests – and as low as possible
>Cover sharp edges and corners
>Do not pile objects higher than the
top edge of the backrest
>For very heavy loads when the rear
seat is not occupied, secure each
safety belt in the opposite buckle,
see illustration.
Securing the cargo in the luggage
compartment >For small, light items, use the rubber-
lined, non-skid side of the floor mat
or secure using the luggage compart-
ment net* or elastic straps, refer to
page 37
>For large, heavy pieces, see your
BMW center for load-securing
devices*. Anchorages located in the
luggage compartment can be used
for fastening the load-securing
devices.
Comply with the information enclosed
with the load-securing devices.

Always position and secure the
load correctly. If you do not, it can
endanger the passengers during brak-
ing or evasive maneuvers.
Do not exceed the approved gross
vehicle weight or the approved axle
loads, refer to page 152. Otherwise the
vehicle's operating safety is no longer
assured and the vehicle will not be in
compliance with the certification regu-
lations.
Do not stow heavy or hard objects in
the passenger compartment without
first securing them. Otherwise they
would be thrown around during braking
and evasive maneuvers and endanger
the occupants.<
Roof-mounted luggage rack*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the mounting points:
To fold up the covers, please use the
tool provided with the roof-rack system.Loading and driving notesBecause roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
When loading, be sure to remember not
to exceed the approved roof weight or
the approved gross vehicle weight or
the axle loads. You will find the specifi-
cations under Technical data on
page 152.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first so
that they are at the bottom. Be sure that
adequate clearance is maintained for
raising the glass sunroof, and that
objects do not project into the opening
path of the luggage compartment lid.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.

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.Up to 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.
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 67: 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.
Follow the same break-in procedure if
either the engine or the differential
should have to be replaced in the
future.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.
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, as well as loss of vehicle control
and braking effectiveness. Reduce your
speed on wet roads. 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 – at a traf-
fic signal, for instance – use caution to
avoid posing a danger to other road
users.
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. 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.

General driving notes
Brakes: do not rest your foot on
the brake pedal while driving.
Even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.
Hydroplaning: when driving on wet or
slushy roads, reduce road speed. If you
do not, a wedge of water can form
between tires 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.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Rear parcel tray: never use it to store
heavy or hard objects; otherwise, occu-
pants could be injured if the vehicle is
braked hard.
Clothes hooks: when suspending cloth-
ing 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 maneu-
vers.<
Portable phone in the vehicleBMW recommends using mobile com-
munications devices, e.g. portable
phones, inside the vehicle with a suit-
able outside antenna. Otherwise, it can-
not be ruled out that the vehicle elec-
tronics and portable phone may
interfere with each other.

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 the ABS system if you apply maxi-
mum pedal pressure – panic stop.
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 83.
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
design of the ABS. When braking while
cornering at high speed or braking dur-
ing high lateral acceleration, or when
braking during a lane change, vehicle
stability is improved and 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 BMW cen-
ter. Higher brake application pres-
sure may be necessary when stopping,
and the vehicle may exhibit a slight ten-
dency to pull to one side. Brake dis-
tances may even be longer. Please
remember to adapt your driving style
accordingly. 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 of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
rotors by brake applications is not
reached.
