2016 BMW M4 ECU

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.

LoadsVehicle 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.
Notes WARNING
A high gross vehicle weight can cause
the tyres to overheat, causing internal damage
and a sudden loss of tyre pressure. Danger of
accidents. Comply with the permitted load in‐
dex of the tyre, and do not exceed the permit‐
ted gross vehicle weight.◀
WARNING
If the permitted total weight and the per‐
mitted axle loads are exceeded, operational
safety of the vehicle is not ensured anymore.
Danger of accidents. Do not exceed the per‐
mitted total weight and permitted axle loads.◀
ATTENTION
Liquids in the boot can cause damage.
Danger of damage to property. Make sure that
no liquids leak out in the boot.◀
WARNING
Loose objects in the interior can be
thrown into the interior during the journey, for
example in an accident or during braking and
evasive manoeuvres. Danger of injury. Secure
loose objects in the interior.◀Stowing transported loads▷Wrap protective material around sharp cor‐
ners and edges of the load.▷Heavy transported load: stow as far for‐
ward and as low down as possible, ideally
directly behind the rear backrests.▷Very heavy transported load: with no pas‐
sengers on the back seat, insert both outer
seat belts into the respective opposite
buckles.▷Fully fold down the rear-seat backrest if
the load is to be stowed accordingly.▷Do not stack storage goods above the up‐
per edge of the backrests.
Securing transported loads
Lashing eyes in the boot
For securing the load four lashing eyes are in
the boot.
Floor net
For securing the load and for keeping small
parts, the floor net can also be used.

Hang the floor net on the eyes in the boot floor.Securing transported loads WARNING
Incorrectly stowed objects can slip or be
thrown into the interior, for example in an acci‐
dent, during braking or evasive manoeuvres.
Vehicle occupants could be hit and injured.
Danger of injury. Stow and secure the objects
and the load correctly.◀
▷Smaller and lighter parts: with tensioning
straps, to secure the floor net or other suit‐
able straps.▷Relatively large and heavy objects: secure
with lashing straps.
Fasten tensioning straps of various kinds to
the lashing eyes in the boot.
Roof rack Note
Roof racks are available as special equipment.
Fastening Follow fitting instruction of the roof rack.
Roof strip with flaps
The mounting points are located on the roof
strip above the doors.
Fold the cover outwards.
Loads
A loaded roof rack alters the vehicle's road be‐
haviour and steering response by shifting its
centre of gravity.
When loading and driving, bear the following in
mind:
▷Do not exceed permitted roof and axle load
as well as the permitted gross weight.▷Make sure that there is sufficient space to
raise and open the Glass Roof.▷Distribute the roof load evenly.▷The roof load must not be spread over a
large area.▷Place heavy items of luggage at the bot‐
tom.▷Securely fasten roof rack, for example with
tensioning straps.▷Do not allow objects to protrude into the
swing range of the boot lid.▷Drive cautiously and avoid sudden acceler‐
ation, braking or cornering.Seite 167LoadsDriving hints167
