Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rearward-facing child-restraint
system – of the kind designed for
infants under 1 year and 20 lbs/9 kg –
would be within the airbag's deploy-
ment range, you should never mount
such a device in the front passenger
seat, since the impact of the airbag
against the child restraint's backrest
could lead to serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
should be tightly secured with the
safety belt after they have outgrown a
booster seat that is appropriate for their
age, height, and weight.
Younger children should be secured in
an appropriate forward-facing child-
restraint system that has first been
properly secured with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child restraint's manufacturer when-
ever you use such a device.
Do not attempt to modify child-restraint
systems. If you do this, the protection
provided by these systems could be
impaired.
Be sure that all occupants – of all ages –
remain properly and securely restrained
at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry recommended
practice for securing child-restraint sys-
tems in motor vehicles.
Child seat securityAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.

Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
DSC starts up automatically each time
you start the engine.The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC. At first, you may
need some time to become accus-
tomed to this system's intervention.
However, it guarantees optimum drive
force and at the same time, the best
possible vehicle stability.<
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 20.
>Indicator lamp flashes: DSC is active
and is controlling the drive torque
based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: DSC has been deacti-
vated via the button or is defective.
Please consult your BMW center for
repairs.
You can continue to drive the vehicle
normally without DSC.

To deactivate DSCPress the button briefly; the indicator
lamp comes on and stays on.
The vehicle does not execute the stabil-
ity-enhancement and traction-control
functions when DSC is deactivated.
We recommend that you deactivate
DSC for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
To reactivate DSCPress the button again; the indicator
lamp goes out.
Flat Tire MonitorThe conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
Controlling the tire pressure is based
on monitoring the rpm that the tires
have relative to each other. A flat tire is
detected and reported because the rpm
suddenly deviate drastically from one
another.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 25 and cor-
rect them, if necessary
3. Initialize the system.

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.

Do not drive on a deflated – flat –
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading can lead to
overheating and internal tire damage.
This can result in a sudden loss of tire
inflation pressure.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This type of problem can be caused by
contact with curbs, etc. This is also true
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or
right. Should this occur, respond by
immediately reducing your speed. Pro-
ceed carefully to the nearest BMW cen-
ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage, up to and including blow-
outs, can endanger the lives of both the
vehicle occupants and other road
users.<
Tire replacementTo maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.DOT quality gradesTreadwear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half – 1
1/2 – times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.TractionThe traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics. highest – B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
