Special operating instructions
Break-in procedures
Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following:
Always obey all official speed limits.
Engine and differential
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed 4,500 rpm or 100 mph/160 km/h.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. Shift gears carefully during
the break-in period.
After replacing components
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Driving notes
Close the luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is closed.
Otherwise, exhaust fumes could enter the inte-
rior of the vehicle.<
Should it be absolutely necessary to drive with
the luggage compartment lid/tailgate open:
1.Coupe: close both windows.
Roadster: close all windows if the convert-
ible top is closed.
2.Greatly increase the air flow from the air
conditioning or automatic climate control,
refer to page62 or65.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Never remove the heat shields installed in
this area, nor apply undercoating to their sur-
faces. When driving, standing at idle or parking
the vehicle, take care to avoid contact between
the hot exhaust system and flammable materi-
als, e.g. hay, leaves, grass, etc. Such contact
could lead to a fire, resulting in serious personal
injury and property damage. Do not touch the
hot exhaust pipes to avoid the risk of injury from
burns.<
Mobile communications in the vehicle
BMW advises against using mobile com-
munications devices, e.g. mobile phones,
inside the vehicle without connecting them
directly to an outside antenna. Otherwise, it
