Break-in procedures
To ensure that your vehicle continues to Tires
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.

Owing to technical factors associated
an extended service life, we request
that you devote careful attention to the
following instructions.
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
We thus ask you to drive with extra care
during the first 200 miles/300 km.
Engine and differential
You can prevent corrosion in the drums
by periodically repeating this proce-
dure.
The first 1,250 miles/2,000 km:
Always obey all official speed limits.
Constantly vary both vehicle and engine
speeds, remembering not to exceed
4,500 rpm or vehicle speeds of over
100 mph / 160 km/h:
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, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
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.<
Always obey all official speed limits.
Do not use full throttle, and avoid
pressing the accelerator beyond the
kickdown point during these initial
miles.
You can then proceed to increase
engine or vehicle speeds once the ini-
tial 1,250 miles/2,000 km have elapsed.
Brake system
Clutch
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 an extended service life
later on.
Approx. 300 miles/500 km must elapse
before the clutch starts to operate at
optimum efficiency. Remember to
engage the clutch carefully during this
initial period.
Please remember to observe the same
break-in procedures if either the engine
or the differential should have to be
replaced later in the course of the vehi-
cle's service life.
