2008 BMW M6 engine

Things to remember when driving
118 Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When driving on wet roads or in heavy rain, it is
a good idea to apply light pressure to the brake
pedal every few miles. Monitor traffic conditions
to ensure that this maneuver does not endan-
ger other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or
steep downhill stretches. Even light but consis-
tent pressure on the brake pedal can lead to
high temperatures, brake wear and possibly
even brake failure.<
Sequential Manual Transmission: do not
drive in idle or with the engine switched
off, otherwise there will be no engine braking
action or support of the braking force and steer-
ing.
Manual transmission: do not drive with the
clutch depressed, in idle or with the engine
switched off, otherwise there will be no engine
braking action or support of the braking force
and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads during brake applications to clean the rotors is
not reached.
This can also lead to long-lasting decreases in
comfort and squeaking noise during braking.
These decreases in comfort can also be pro-
duced by long braking maneuvers with a low
pedal pressure.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
For technical information about the brake sys-
tem, refer to page121.
When vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page51,
otherwise they could be damaged due to the
width of the vehicle.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Make sure that no fluids leak in the cargo
bay; otherwise the vehicle could be dam-
aged.<

BMW M6 Engineering
V10 High Output Engine
With a 305 cu in/5 liter displacement, the high-
speed V10 engine generates a maximum out-
put of 373 kW and a maximum torque of
384 lb ft/520 Nm. Its spontaneous response
characteristics yield a very broad usable engine
speed range. At the maximum engine speed of
8250 rpm, the flow of fuel is interrupted in order
to protect the engine. Due to the powerful
engine dynamics, when the vehicle is at rest,
the maximum engine speed is limited to
7000 rpm.
Warming up
The emissions control system causes the
V10 high-output engine to have slightly
rougher running characteristics during its
warm-up phase.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the sys-
tem design.
For additional information on warming up, refer
to Tachometer on page69 and Engine oil tem-
perature on page70.
Compound brake
Your BMW M6 has a high-performance brake
s y s t em wi t h p e rf o ra t e d c o m p o u n d b r a k e r o t o r s .
Due to the special structural features of these
brake rotors, function noises occur during brak-
ing, but this has no effect on the performance,
operating safety, and stability of the brakes.
Braking correctly
In order to keep the brake system in optimum
condition, it is useful to put them under load at
regular intervals in accordance with the nature
of the vehicle.
Also refer to Corrosion on brake rotors on
page118.
Drive train
In your BMW M6, particular importance was
attached to the direct connection of the engine
to the drive system. Due to the torsionally rigid
design of the drive train, the transmission of the
torque is also audible, as is customary in a
sports car. As a result, load shifts can be dis-
tinctly audible. This does not in any way impair
the function or the service life of the compo-
nents.

Telephoning

Telephoning
The concept
Your BMW is equipped with a full mobile phone
preparation package. After a suitable mobile
phone has been paired in the vehicle once, you
can operate the mobile phone via iDrive, with
the buttons on the steering wheel and by voice.
A mobile phone that has been paired once is
automatically detected again as soon as it is
brought back inside the vehicle, provided that
the engine is running or the ignition is switched
on. The pairing data of up to four mobile phones
can be stored simultaneously. If several mobile
phones are detected simultaneously, the most
recently paired mobile phone can be operated
via the vehicle.
Using a phone in your vehicle
Using snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW cen-
ter which mobile phones snap-in adapters are
offered for.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate operating instructions for a
detailed description of safety precautions and
information, we request that you direct your
particular attention to the following:
Only make entries when traffic conditions
allow you to do so. Do not hold the mobile
phone in your hand while you are driving; use
the hands-free system instead. If you do not
observe this precaution, your being distracted can endanger vehicle occupants and other road
users.<
Suitable mobile phones
Ask your BMW center which mobile phones
with a Bluetooth interface are supported by the
mobile phone preparation package or which
mobile phones will fit in the snap-in adapters
they offer. These mobile phones support the
functions described in this Owner's Manual,
provided they are running a certain software
version. Malfunctions can occur with other
mobile phones.
Care instructions
You can find what you need to know about car-
ing for your mobile phone in the separate Caring
for your vehicle brochure and in the mobile
phone operating instructions.
Operating options
You can operate the mobile phone* using:
>Buttons on steering wheel, refer to page11
>iDrive, refer to page16
>Voice commands, refer to page187
>Programmable memory/direct selection
buttons, refer to page21
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
Placing phone calls with BMW Assist
system*: BMW Assist calls
You can use the BMW Assist system via the
hands-free unit for BMW Assist calls.
When the status information "BMW Assist" or
"BMW Service" is displayed in "Communica-
tion", only BMW Assist calls are possible.

Changing between mobile
phone and hands-free system
From mobile phone to hands-free
system*
You can continue calls begun outside the Blue-
tooth range of the vehicle via the hands-free
system when the engine is running or the igni-
tion is switched on. Depending on your mobile
phone, the system automatically switches over
to the hands-free mode.
For mobile phones that do not automatically
switch over to the hands-free mode:

you can also continue the call via the mobile
phone if necessary, depending on the mobile
phone model. Act according to what is shown
on the mobile phone display, refer to the oper-
ating instructions of your mobile phone.
As an alternative, you can deactivate the Blue-
tooth link.
Depending on your mobile phone model, poor
reception of the wireless communications net-
work can result in the system switching from
the hands-free system to the mobile phone.
Operation by voice*
The concept
You can operate your mobile phone without
having to remove your hands from the steering

When handling fuels, follow the safety
precautions posted at the filling station. Otherwise, there is a danger of personal injury
and property damage.<
Place the fuel filler cap in the bracket attached
to the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, otherwise this
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 18.5 US gal/70 liters, including the
reserve capacity of approx.4 US gal/15 liters.

Fuel specifications
Never used leaded gasoline; it will perma-
nently damage the catalytic converter.
Do not use E85, i.e. fuel that consists of 85%
ethanol, or Flex Fuel. Otherwise permanent
damage to the engine and the fuel supply sys-
tem will result.<
Required fuel
Super Premium Gasoline/AKI 93
Always use this premium grade fuel to obtain
maximum fuel economy and performance.
The minimum approved fuel grade is AKI 91.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has demonstrated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels
containing up to and including 10 % ethanol or
other oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will
not void the applicable warranties with respect
to defects in materials or workmanship.
The use of poor-quality fuels may result in
problems relating to drivability and start-
ing, and to a tendency to stall, especially under
certain environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
