Break-in procedure
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following:
Engine and differential
Up to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
4500 rpm and/or 105 mph (170 km/h)
during this initial period. Comply with Brake system
the legal speed limit at all times.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once 1,200 miles (2,000 km) have
elapsed, engine speeds and road
speeds can gradually be increased.
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.
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 hydroplaning,
and can lead to partial or complete
loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Approximately 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 (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 applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
car with the engine shut off – when towing,
for instance – substantially higher
levels of pedal force will be required to
brake the vehicle.<
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).
