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
the legal speed limit at all times.

Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.

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).

wet or slushy roads, a wedge of
water may form between the tire and

referred to as aquaplaning, or hydro-
planing, and can lead to partial or com-

and braking effectiveness. Reduce your
speed on wet roads.

Brake system
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 traf-
fic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.

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 tow-
ing, for instance – substantially higher
levels of pedal force will be required to
brake the vehicle.
