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.

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.

3.Take the filler hose of the sealant container
that was previously connected to the tyre
valve and connect it to the free connection
on the sealant container.
This can prevent sealant residues from es‐
caping from the container.4.Pack empty sealant container to avoid soil‐
ing in the boot.5.Store Mobility system in the vehicle again.
Spreading sealant compound
Immediately drive for approximately
10 km/5 mi to evenly distribute the sealing
compound in the tyre.
Do not exceed a speed of 80 km/h/50 mph.
If possible, do not drive slower than
20 km/h/12 mph.
Correcting the tyre inflation pressure
1.Stop in a suitable area.2.Bolt the connecting hose of the compres‐
sor directly onto the tyre valve.3.Insert the plug into the socket on the inside
of the vehicle.4.Correct tyre inflation pressure to 2.5 bar.▷Increase pressure: switch on the com‐
pressor with the engine running or the
ignition switched on.▷Reduce pressure: press the button on
the compressor.
Continuing with journey
Do not exceed maximum permitted speed of
80 km/h, approximately 50 mph.
Reinitialise runflat indicator.
Reinitialise Tyre Pressure Monitor.
Have the punctured tyre and the sealant con‐
tainer of the Mobility system replaced as soon
as possible.
Snow chains
Fine-link snow chains Only certain fine-link snow chains have been
tested, found safe for use in traffic, and cate‐
gorised as suitable by the manufacturer of your
vehicle.
Information regarding suitable snow chains is
available from a Service Partner or a qualified
specialist workshop.
Using Snow chains may only be used in pairs on the
rear wheels with tyres of the following sizes:▷255/40 R 18.▷255/35 R 19.
Observe the snow chain manufacturer's notes.
Ensure that the snow chains are always ade‐
quately taut. Re-tighten them if necessary in
accordance with the chain manufacturer's in‐
structions.
Do not initialise the runflat indicator with snow
chains fitted, as the instrument might other‐
wise issue an incorrect reading.
Do not initialise the Tyre Pressure Monitor with
snow chains fitted, as the instrument might
otherwise issue an incorrect reading.
When driving with snow chains, activate M Dy‐
namic Mode briefly if necessary.
