BMW M4 TechnologyVehicle equipment
This chapter describes all standard, national
and special equipment provided in the model
series. Equipment not available in the vehicle is
therefore also described, for example the se‐
lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
High performance engine The high performance engine generates a
maximum power of 317 kW and a maximum
torque of 550 Nm from 3 litres of capacity.
With its spontaneous responsiveness, a very
broad usable engine speed range is produced.
The maximum engine speed is electronically regulated at 7,600 rpm. Due to the powerful
engine dynamics, the maximum engine speed
is limited when the vehicle is stationary.
Driving hot During the engine warm-up phase, the high
performance engine runs slightly more roughly
due to the emission control.
When the engine is cold, the exhaust has a
slightly metallic undertone, depending on the
system.
Other information for hot driving: engine speed
counter, see page 84, and engine oil tempera‐
ture, see page 84.
M compound brakes The high performance brake system has venti‐
lated compound brake discs.
Depending on design requirements, function
noises may occur when braking. However, thishas no effect on the performance, operational
safety and stability of the brakes.
Braking correctly
To keep the brake system in optimum condi‐
tion, it is desirable to load them at regular inter‐
vals depending on the nature of the vehicle.
M Carbon ceramic brakes
The high performance braking system has per‐
forated carbon ceramic brake disks and is de‐
signed for racetrack operation.
Depending on the material-specific properties, there can be increased functional noises when
braking, particularly when it is wet, shortly be‐
fore the vehicle comes to a stop. This has no
effect on performance, operational safety and
endurance of the brakes.
Due to the effect of wet and salt spray, for ex‐
ample, after using a car wash, condensation
overnight etc., the braking effect may corre‐
spond to a conventional braking system. This
can be detected as reduced braking effect and
compensated for by higher pedal pressure, as
needed.
Clean brake discs and brake calliper before
washing in an automatic car wash with a steam
sprayer or high pressure cleaner to avoid en‐
crustations and caking, for example, due to salt
crystals with a related stationary period. The cleaning effect of automatic car washes gener‐
ally not sufficient for this in the wheel area.
Also follow the information on this under vehi‐
cle washing, see page 208, and safe braking,
see page 163.Seite 160Driving hintsBMW M4 Technology160

Drivetrain
In this vehicle, particular attention is paid to the
direct connection from the engine to the drive‐
train. Due to the torsionally stiff design of the
drivetrain, as usual in a sports car, the trans‐
mission of the torque is can also be heard.
When there are load changes, it can therefore
cause clattering noises. They do not affect the
functioning or durability of the components.
Driving on a racing track
Requirements For driving on a racing track:▷Participation in a training course from
BMW Driving Experience.▷Check engine oil level and top up with en‐
gine oil as required.▷Have vehicle checked by a Service Partner
or a qualified specialist workshop.
Notes
Racing track operation causes increased wear. The vehicle is not designed for use in motor‐
sport competitions. This wear is not covered by the warranty.
The standard brake pads and the wear dis‐
plays are not designed for racing track opera‐
tion. Further information and advice are avail‐
able from a Service Partner or a qualified
specialist workshop.

Running in General
Moving parts need a certain time to achieve
maximum operating efficiency as a unit.
The following information helps to achieve
maximum service life and efficiency of the ve‐
hicle.
Do not use Launch Control, see page 77, when
running in.
Engine, gearbox and differential
Up to 2000 km, 1200 miles Drive with alternating revolutions and speeds,
but do not exceed 5500 rpm and 170 km/h, ap‐ proximately 106 mph.
In principle, avoid full load or kick-down.
At 2000 km, 1200 miles
Have maintenance conduct a drive-in service.
From 2000 km, approximately
1200 miles to 5000 km, approximately
3100 miles
Revolutions and vehicle speed can gradually
be increased to a continuous speed of
220 km/h, approximately 137 mph.The maximum speed of 250 km/h, approxi‐
mately 155 mph is only to be used briefly, for
example when overtaking.
Tyres New tyres do not achieve their full road
grip immediately, for production reasons.
During the first 300 km, 200 miles, drive mod‐
erately.
Brake system
Brake pads and discs of the M compound
brakes only achieve a favourable wear and
contact pattern after approximately 500 km,
approximately 300 miles. Drive moderately
during this running-in period.
Brake discs and pads of the M carbon ceramic
brakes only achieve a favourable wear and
contact pattern after approx. 1000 km, approx.
600 miles. Drive moderately during this run‐
ning-in period.
Clutch
The clutch only begins to function optimally at
approximately 500 km, approximately
300 miles. Engage the clutch gently during this
running-in period.
After fitting new parts The same running-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.Seite 162Driving hintsDriving precautions162

General driving information
Closing the boot lid WARNING
An open boot lid projects beyond the ve‐
hicle, and in the event of an accident, braking
or avoidance manoeuvres, it can endanger ve‐ hicle occupants and other road users, or dam‐
age the vehicle. There is also the danger of ex‐
haust fumes entering the interior of the
vehicle. Danger of injury or damage to prop‐
erty. Do not drive with the boot lid open.◀
If there is no alternative to driving with the tail‐
gate open:▷Close all windows and the Glass Roof.▷Turn up the blower to a high output level.▷Maintain moderate speed.
Hot exhaust system
WARNING
During driving, high temperatures can be
generated under the body, for example be‐
cause of the exhaust system. If flammable ma‐
terials, for example leaves of grass, come into
contact with hot parts of the exhaust system,
these materials can catch fire. Danger of injury
or damage to property.
Never remove the heat shields fitted here, or
apply underseal to them. Make sure that when driving, idling or parking, no flammable materi‐
als can come into contact with hot vehicle
parts. Do not touch the hot exhaust system.◀
Radio signals WARNING
Certain vehicle functions may be affec‐
ted by interference from high-frequency radio
signals. Such signals are output from a series
of transmission systems, for example, from air
traffic beacons or relay stations for mobile tele‐
communications.
We recommend you consult a Service Partner
or a qualified specialist workshop should you
experience any difficulties.◀
Mobile communication equipment WARNING
The vehicle's electronics and mobile
radio devices can interfere. The transmission
operation of mobile radio devices generates
radiation. Danger of injury or damage to prop‐
erty. If possible, only use mobile radio devices,
e.g. mobile telephones, in the interior with di‐
rect connection to an external antenna to ex‐
clude mutual interference and to dissipate the
radiation from the vehicle's interior.◀
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tyres and the road.
This situation, known as aquaplaning, means
that the tyre can actually lose contact com‐
pletely with the road surface and the vehicle
can neither be steered nor the brakes properly
applied.
Wading ATTENTION
Driving through excessively deep water
too fast can result in water entering the engine
compartment, electrical system or transmis‐
sion. Danger of damage to property. When
driving through water, do not exceed the maxi‐
mum specified water depth and maximum
fording speed.◀
Only if the water is calm and only up to a water
depth of max. 25 cm, approximately 9.8 inches
and at this depth drive no faster than walking
speed up to 5 km/h, approximately 3 mph.
Safe braking Your vehicle is equipped with ABS as standard.Seite 163Driving precautionsDriving hints163
Online Edition for Part no. 01 40 2 964 013 - VI/15

Applying the brakes fully is the most effective
way of braking in situations in which this is
necessary.
The vehicle can be steered. Any obstacles can
be avoided with steering wheel movements
that are as calm as possible.
A pulsing of the brake pedal shows that ABS is
regulating.
In certain braking situations, the perforated
brake disks can cause functional noise. How‐
ever, this has no effect on the efficiency and
operational safety of the brakes.
Objects in the range of movement of
the pedals and in the footwell
WARNING
Objects in the driver's footwell can re‐
strict the pedal travel, or block a pedal that has
been pressed. Danger of accidents. Stow
items in the vehicle so that they are secure and
cannot get into the driver's footwell. Only use
floor mats that have been categorised as ap‐
propriate for the vehicle and that can be fas‐
tened accordingly. Do not use any loose floor
mats, and do not place several floor mats on
top of one another. Make sure that there is suf‐
ficient space for the pedals. Ensure that the
floor mats are securely reattached after having
been removed, for example for cleaning.◀
Wet roads
In damp weather, if road grit has been spread
or there is heavy rain, apply the brakes lightly
every few kilometres/miles.
In doing so, do not obstruct other road users.
The resulting heat dries the brake discs and
pads.
The braking force will be available immediately
if needed.Downhill gradients
WARNING
Even slight, continuous pressure on the
brake pedal can cause overheating, brake pad
wear or even brake system failure. Danger of
accidents. Avoid excessive loads on the
brake.◀
WARNING
When idling or with the engine switched
off, safety-relevant functions are restricted or
no longer available, for example the braking ef‐
fect of the engine or power assistance for the
braking force and steering. Danger of acci‐
dents. Do not drive at idle speed or with the
engine switched off.◀
When driving on long or steep downhill
stretches, use the gear in which the least brak‐
ing is required. Otherwise the brake system
can overheat and braking action is reduced.
Manual gearbox:
The braking effect can be additionally in‐
creased by shifting down, even into first gear, if
applicable.
M double clutch transmission:
The braking action of the engine can be boos‐
ted further by shifting down in sequential
mode, see page 75.
Corrosion of the brake disc Corrosion of the brake discs and contamina‐
tion of the brake pads increase with the
following circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Seite 164Driving hintsDriving precautions164
Online Edition for Part no. 01 40 2 964 013 - VI/15

Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensate when vehicle is parked
When using the automatic air conditioning,
condensation water develops that exits under‐
neath the vehicle.
Traces of water on the ground are normal.
Ground clearance ATTENTION
If there is insufficient ground clearance,
the front or rear spoiler can touch the ground,
for example at curb edges or when driving into
underground car parks. Danger of damage to
property. Make sure that there is sufficient
ground clearance.◀
When driving down from kerb edges, select
the following program with the adaptive M sus‐
pension, see page 126, to keep the ground
clearance as uniform as possible: "Sport Plus"
M Driver's Package: driving in
maximum speed range
WARNING
At high speeds, damage to vehicle parts
can unfavourably influence driving properties.
These include tyres, underbody and parts for
improving aerodynamics. Danger of accidents.
Have damage rectified by a Service Partner or
a qualified specialist workshop. Do not drive at
high speed until the damage has been re‐
paired.◀Seite 165Driving precautionsDriving hints165

ted speed for the tyres fitted must be dis‐
played in the driver's field of view. The sticker
is available from a Service Partner or a qualified
specialist workshop.
If winter tyres are fitted, observe and comply
with the respectively permitted maximum
speed.
Interchanging front and rear wheels
The manufacturer of your vehicle advises
against interchanging the front and rear
wheels. This could impair vehicle handling
Such a change is not permitted in vehicles with
different tyre or rim dimensions on the front
and rear axles.
Tyre storage
Store wheels and tyres in a cool, dry and pref‐
erably dark place when not in use.
Protect tyres against contamination from oil,
grease and fuel.
Do not exceed the maximum tyre pressure in‐
dicated on the tyre's side wall.
Remedying flat tyres Safety measures▷Park the vehicle on a solid surface and as
far away from moving traffic as possible.▷Switch on hazard warning lights.▷Protect the vehicle against rolling, by ap‐
plying the parking brake.▷Engage the steering wheel lock in the
straight ahead position of the wheels.▷Allow all vehicle occupants get out of the
vehicle and guide them out of the danger
area, for example behind the crash barrier.▷Set up warning triangle an appropriate dis‐
tance away.Mobility system
Principle With the mobility system, minor tyre damage
can be quickly sealed, to allow you to drive on.
To do that, liquid sealant is pumped into the
tyres which encloses the damage from the in‐ side when it hardens.
The compressor can be used to check the tyre
inflation pressure.
Notes▷Please observe the notes on the applica‐
tion of the Mobility system which are on
the compressor and the sealant container.▷Applying the Mobility system can be inef‐
fective for tyre damage as from a size of
approximately 4 mm.▷Contact a Service Partner or a qualified
specialist workshop if you are unable to put
the tyre back in operation.▷If possible, foreign matter that has penetra‐
ted the tyre should remain inside the tyre.▷Remove the speed limit sticker from the
sealant container and attach to the steer‐
ing wheel.▷Using sealants can damage the TPM wheel
electronics. If sealant is used, check the
electronics as soon as you get an opportu‐
nity and have them replaced if necessary.
DANGER
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to
penetrate the vehicle. The exhaust gas con‐
tains carbon monoxide, which is colourless and
odourless, but highly toxic. In enclosed spaces,
the exhaust fumes can also build up outside
the vehicle. Danger of fatal injury. Keep the ex‐
haust pipe clear and ensure sufficient ventila‐
tion.◀
Storage
Mobility system is located under boot floor.
