High performance V8 engine
The high-revving V8 engine draws a maximum
power of 420 hp/309 kW and a peak torque of
295 lb ft/400 Nm from a displacement of
244 cu in/4 liters. Its spontaneous response
results in a very wide effective rpm range. The
maximum engine speed lies at 8,400 rpm and is
electronically controlled. Due to the high engine
dynamics, the maximum engine speed is lim-
ited to 7,000 rpm when the vehicle is standing.
Warming up the engine
During the warm-up phase, the high-perfor-
mance V8 engine runs a little more roughly due
to its emissions control system.
For technical reasons, the exhaust system
sounds slightly metallic when the engine is
cold.
For further information on warming up the
engine, refer to Tachometer on page67 and
Engine oil temperature on page68.
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
page115.
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.

Under the hood
218
Under the hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are unfamiliar with the statutory guide-
lines, have any work on the vehicle performed
only by a BMW center or by a workshop that
work according to BMW repair procedures with
correspondingly trained personnel. If this work
is not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
Hood
Releasing
Pull the lever.
Opening
To avoid damage, make sure that the
wiper arms are against the windshield
before you open the engine compartment. Do
not open the engine hood before the engine has
cooled down, otherwise injuries may result.<
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 20 in/
50 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may
result.
If you see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

Replacing components
228 4.Adjust the tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on, pro-
ceed as follows:
>To increase the inflation pressure:
Switch on the compressor, position I. To
check the current inflation pressure set-
ting, briefly switch off the compressor.
Do not let the compressor run for
more than 10 minutes, otherwise the
device will overheat and may be dam-
aged.<
>To reduce the inflation pressure: turn
screw 8 on the pressure gauge.
If the inflation pressure is not maintained,
drive the vehicle a second time, refer to
Distributing the sealant. Then repeat steps 1 to
4.
Use of the M Mobility System may be ineffec-
tual for tire damage larger than approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page230, or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made roadworthy with the M Mobility
System.<
The tire inflation pressure must be at least
29 psi/200 kPa. If it is not, do not continue
driving.<
Continuing your trip
Do not exceed the maximum allowable
speed of 50 mph/80 km/h to avoid the risk
of an accident.<
Reinitialize the Flat Tire Monitor, refer to
page85 for more information.
Have the faulty tire and the sealant bottle of the
M Mobility System replaced as soon as possi-
ble.<
Changing wheels
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
ma te. Your BM W center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page231.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page74.
