For further information on warming up the
engine, refer to Tachometer on page
Engine oil temperature on page 62.
Compound brake
Your BMW M3 is equipped with a high-perfor-
mance brake system with perforated com-
pound brake discs.
Due to special design features of the perforated
compound brake discs, operating noise is audi-
ble during braking. However, this does not
affect the brake's performance, safe operation
or stability under load.
Braking correctly
To keep the brake system in optimal condition,
it is advisable to apply the brakes at regular
intervals as appropriate for the character of the
vehicle.
Refer also to Corrosion on brake rotors on
page 110.

Drive train

In your BMW M3, special emphasis was placed
on the direct connection between the engine
and drive. The torsionally rigid execution of the
drive train results in acoustic feedback of the
torque, as is typical in sports cars. Clacking
sounds can arise during load changes. They do
not impair functionality or shorten the lifespan
of any component.
Driving on a race track
BMW recommends the following measures
before driving on a race track:
>
Participate in a BMW driver training course

Operation on a race track can lead to
increased wear. The BMW M3 is not
designed for use in competitive motorsports.
This wear is not covered by the vehicle war-
ranty.<

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
page 78, 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
page 92.
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-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust pipes, e.g.
when loading the cargo bay, otherwise there is a
risk of burn
, select the "Sport" program, refer to
injuries.<
