Break-in procedures
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following information.
Tires
To avoid corrosion, repeat this proce-
dure from time to time.
Due to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
after an initial break-in period. We thus
ask you to drive with extra care during
the first 200 miles/300 km.
The brake lamps do not come on
when the parking brake is set.
Engine and differential
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.<
The first 1,250 miles/2,000 km:
Constantly vary both vehicle and engine Always obey all official speed limits.
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.<
Always obey all official speed limits.
Clutch
Do not use full throttle, and avoid
pressing the accelerator beyond the
kickdown point during these initial
miles.
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.
You can then proceed to increase
engine or vehicle speeds once the ini-
tial 1,250 miles/2,000 km have elapsed. Brake system
Please remember to observe these
same break-in procedures if either the
engine or the differential should have to
be replaced later in the course of the
vehicle's service life.
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.
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 – provided that
traffic conditions allow you to do so.
