2016 BMW M4 brake

Front-end collision warning
with city braking function
Principle The system can help avoid accidents. If an ac‐
cident cannot be avoided, the system helps to
reduce the collision speed.
The system warns of the possible risk of colli‐
sion and brakes automatically, as necessary.
The automatic braking intervention is done
with limited force and duration.
The system is controlled by a camera in the
area of the rear-view mirror.
The front-end collision warning is also avail‐
able if the Cruise Control is disabled.
When deliberately approaching a vehicle, the
approach control warning and braking inter‐
vention are activated later to avoid unjustified
system responses.
General
The system warns from approximately 5 km/h,
approximately 3 mph in two stages of any risk
of collision with vehicles. The timing of these
warnings may vary depending on the current
driving situation.
Up to approximately 60km/h, 35 mph.
Detection range
Objects are taken into account if they are de‐
tected by the system.
Notes
WARNING
Displays and warnings do not take your
personal responsibility from you. System limi‐
tations can mean that warnings or system re‐
sponses are not issued, are issued too late, or are issued incorrectly. Danger of accidents.
Adapt driving style to the driving conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.◀
WARNING
Due to system limitations, there may be
malfunctions of individual functions when tow-
starting/towing with activated Intelligent Safety Systems, for example approach control warn‐
ing with light braking function. Danger of acci‐
dents. Switch off all Intelligent Safety Systems
before tow-starting/towing.◀

Warning with braking function
Display
If there is a risk of collision with a detected ve‐
hicle, a warning symbol is shown in the instru‐
ment cluster and in the Head-Up Display.SymbolMeasureSymbol illuminates red: advance
warning.
Increase braking and distance.Symbol flashes red and an acoustic
signal sounds: acute warning.
System indicates that you must
brake and/or manoeuvre the vehicle
yourself.
Advance warning
An advance warning is shown, for example if a
danger of collision is anticipated or there is a very short distance to a vehicle ahead.
The driver must intervene personally if there is
an advance warning.
Acute warning with braking function
An acute warning is shown in the event of an
immediate collision if the vehicle approaches
an object with relatively high differential speed.
The driver must intervene personally if there is
an acute warning. If necessary, the driver is as‐
sisted by slight automatic brake intervention if
there is a risk of collision.
An acute warning can be triggered even with‐
out a previous advance warning.
Brake interventionThe warning requires to take action yourself.
Maximum braking force is used during a warn‐
ing. In order for braking force support to be
used, it is necessary for the brake to be
pressed sufficiently quickly and powerfully. In
addition, the system may also support with a
small amount of braking if there is the risk of a

collision. The vehicle can be braked at low
speed until it comes to a stop.
Manual gearbox: When brakes are engaged
until it comes to a stop, the engine may shut
off.
There will only be brake intervention if Dy‐
namic Stability Control, DSC is activated and
M Dynamic Mode MDM is not activated.
Braking can be discontinued either by pressing
the accelerator pedal or by actively moving the
steering wheel.
Detection of objects can be restricted. Limita‐
tions of the detection range and functional re‐
strictions are to be considered.
System limits
Detection range
The detection ability of the system is limited.
For this reason, system responses may be
missing or delayed.
It is possible that the following are not detec‐
ted:▷Slow-moving vehicle when approaching at
high speed.▷Vehicles suddenly cutting in or decelerat‐
ing heavily.▷Vehicles with unusual rear view.▷Two-wheeled vehicles ahead.
Restrictions of the function
The function can be restricted, for example in
the following situations:
▷In thick fog, rain, spray or snowfall.▷On sharp bends.▷When restricting or deactivating vehicle
stability control systems, for example DSC
OFF.▷If the field of view of the camera in the mir‐
ror is soiled or covered.▷Up to 10 seconds after starting the engine
using the start/stop button.▷During the calibration process of the cam‐
era immediately after the vehicle is sup‐
plied.▷When there is sustained glare effect due to
light opposite, for example the sun low in
the sky.
Sensitivity of the warnings
The greater the sensitivity of the warning set‐
tings, for example warning time, the more
warnings will be displayed. As a result, there
may be an increased number of incorrect
warnings.
Person warning with city
braking function
Principle The system can help to avoid accidents with
pedestrians.
The system warns of the possible risk of colli‐
sion with pedestrians in the urban speed area
and also contains a braking function.
The system is controlled by the camera in the
area of the rear-view mirror.
General
The system warns with sufficient brightness
from approx. 10 km/h, approx. 6 mph up to ap‐
prox. 60 km/h, approx. 35 mph of any risk of
collision with pedestrians and supports this by
briefly applying the brakes before a collision.
Here, persons are taken into account if they
are located within the detection range of the
system.

The detection capacity of the camera is limi‐
ted.
This is why it can occur that no warnings are
issued or they are issued late.
It is possible that the following are not detec‐
ted:▷Partially concealed pedestrians.▷Pedestrians who are not detected as such
because of the viewing angle or contour.▷Pedestrians outside the detection range.▷Pedestrians under a height of approxi‐
mately 80 cm, 32 in.
Restrictions of the function
The function may be restricted or not available
in the following situations, for example:
The function may be available on a limited ba‐
sis in the following situations, for example:
▷In thick fog, rain, spray or snowfall.▷On sharp bends.▷When deactivating vehicle stability control
systems, for example DSC OFF.▷If the field of view of the camera and/or the
windscreen is dirty or covered.▷Up to 10 seconds after starting the engine
using the start/stop button.▷During the calibration process of the cam‐
era immediately after the vehicle is sup‐
plied.▷When there is sustained glare effect due to
light opposite, for example the sun low in
the sky.▷In the dark.
Lane departure warning
Principle This system warns if the vehicle leaves the
lane, when the vehicle is on roads with lane
markings and travelling above a given speed.
Depending on country version, this speed is
between 55 km/h, approximately 35 mph and
70 km/h, approximately 45 mph.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.

Manual speed limiterPrinciple With the system, the speed can be restricted
from a value of 30 km/h/20 mph. There are no
restrictions below the set speed limit.
Exceeding the speed limit In particular situations the speed limit can be
deliberately exceeded by accelerating strongly.
The system gives a warning if the travelling
speed exceeds the set speed limit.
No brake intervention
If the set speed limit has been reached or unin‐
tentionally exceeded (for example driving
downhill) there is no brake intervention.
If you set a speed limit during the journey
which is below the current speed, the vehicle
rolls until the driving speed drops below the
speed limit.

Function
After fastening the belt, the front belts are au‐
tomatically pretensioned once when driving
away.
When driving in critical situations, the following
individual functions become active as required:▷The front belts are automatically preten‐
sioned.▷The windows are automatically closed.▷The Glass Roof automatically closes.
After a critical driving situation without acci‐
dent, the front belts are released again. All
other systems can be put back into the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and open the seat belt
using the red button in the lock section. Fasten
the seat belt again before continuing your jour‐
ney.
PostCrash The system can automatically bring the vehicle
to a standstill in certain accident situations
without the involvement of the driver. The risk
of a further collision and its consequences can
thereby be reduced.
By depressing the brake pedal, the vehicle can
be decelerated much faster. The automatic
braking is interrupted as a result. By pressing
the accelerator pedal, automatic braking is also
interrupted.
After reaching a standstill, the brake is auto‐
matically triggered. Then secure the vehicle
against rolling away.

Driving stability control systemsVehicle equipmentThis 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.
Anti-lock Brake System,
ABS
ABS prevents the wheels from locking when
the brakes are applied.
Steering control is retained even in the event
of full braking, enhancing active road safety.
ABS is ready to operate each time the engine
is started.
Brake assist When brake is pressed quickly, this system au‐
tomatically applies maximum braking power
assistance. With full braking, this keeps the
braking distance as short as possible. It also
makes full use of the advantages offered by
ABS.
Maintain pressure on the brake during the en‐
tire brake application.
M Drive
