To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following instructions:
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 procedure very
closely. Doing this, you will create the
basis for a long, optimum service life.
<
Engine and differential
>
Until a mileage reading of 1,200 miles
(2,000 km): drive at varying engine
and road speeds, but do not exceed
the following engine speeds 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.
>
After you have monitored the break-
in period for 1,200 miles (2,000 km),
you can begin to gradually increase
both the engine speed and road
speed.
You should also comply with these
break-in procedures if the engine or
differential is replaced later in the
course of the vehicle service life.
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.
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 aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads.
<
Brake system
Approximately 300 miles (500 km) must
elapse before the brake pads and disks
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 traffic
signal, for instance), provided that
traffic conditions allow you to do so. To
avoid corrosion, repeat this procedure
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
towing, 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 shift
roughly.
