2016 BMW M4 warning light

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.

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

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.
