Special operating instructions
Break-in procedures
To 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.
<
Engine and differential
Up to 1,250 miles/2,000 km:
Drive at varying engine and road
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.
Transmission
The 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.
Tires
Due 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 system
Approx. 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.
<
Clutch
The 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 parts
Follow the same break-in procedures if
any of the components mentioned
above have to be replaced in the future.
