WARNING
When driving with a roof load, for exam‐
ple with a roof rack, the higher centre of gravity
can mean that driving safety is no longer guar‐
anteed in critical driving situations. Danger of
accident or damage to property. Do not deacti‐
vate Dynamic Stability Control DSC when driv‐
ing with a roof load.◀
Overview

M Dynamic Mode
M Dynamic Mode allows driving with higher
longitudinal and transverse acceleration on dry
carriageways, but with restricted drive stability.
Only in the absolute limit of the range does the
system engage for stability purposes by re‐
ducing the engine power and by brakes ap‐
plied to the wheels. In this driving situation, ad‐
ditional steering corrections may be required.
WARNING
With activated M Dynamic Mode stabilis‐
ing engagements are only carried out to a re‐
duced degree. Danger of accident or damage
to property. Adapt to the traffic conditions. Ob‐
serve the traffic situation and intervene actively
if the situation warrants it. Do not move the
steering wheel with unnecessary force in case
of warnings.◀

Servotronic
Principle The Servotronic varies the steering force re‐
quired when steering, depending on the
speed. At low speeds the steering force is
heavily supported, in other words a slight force
is needed when steering With increasing
speed the support for the steering force is re‐
duced.
In addition, steering force is adapted according
to drive program, giving a sporty/direct or com‐
fortable steering response.
Programs Adjustment possibilities of the steering force:▷"Comfort": low.▷"Sport": medium.▷"Sport Plus": high.

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
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.

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.
