Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 5,500 rpm or a
road speed of 105 mph/170 km/h.
Do not depress the accelerator all the way.
From 1,200 miles/2,000 km to
3,000 miles/5,000 km
Engine and road speeds can be increased grad-
ually up to a traveling speed of 135 mph/
220 km/h. Use the maximum speed only for
brief intervals, e. g. when passing.
Transmission
The transmission begins functioning at an opti-
mal level only after a distance of approx.
300 miles/500 km. Do not exceed engine
speeds of 5,500 rpm during this period.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. 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. During this break-in period,
engage the clutch gently.
Following part replacement
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.
General driving notes
Clearance
Mind the limited clearance of the BMW
M3, e. g. when driving into underground
parking garages or over obstacles. If equipped
with EDC
*, select the "Sport" program, refer to
page84, when driving off curbs to keep clear-
ance as even as possible. Otherwise the vehicle
may be damaged.<
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If the vehicle must be driven with the luggage
compartment lid open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page98.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
