Break-in procedures
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
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
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles/300 km.
observe the following suggestions.
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.<
Up to 1,250 miles/2,000 km:
Constantly vary both vehicle and engine Obey your local and state maximum
speeds, remembering not to exceed
4,500 rpm or vehicle speeds of over
100 mph / 160 km/h:
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 hydroplaning, and can
lead to partial or complete loss of trac-
tion, as well as loss of vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Obey your local and state maximum
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
You should also observe the same
break-in procedures if the engine or dif-
ferential should have to be replaced
later in the course of the vehicle's 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 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 traf-
fic signal, for instance – provided that
traffic conditions allow you to do so.
