Runflat indicator RPA
Principle The system identifies a loss of tyre pressure
by comparing the speeds of rotation of the in‐
dividual wheels while the vehicle is in motion.
If a tyre loses pressure, its diameter changes.
This in turn alters the rotational speed of the
corresponding wheel. This is detected and re‐
ported as a flat tyre.
The system does not measure the tyre pres‐
sures as such.
Operating requirements
The system must have been initialised with
correct tyre inflation pressure, otherwise relia‐
ble signalling of a flat tyre cannot be assured.
Each time the tyre pressure is adjusted or a
tyre or wheel is changed, initialise the system
again.
Status display The current status of the runflat indicator can
be shown on the Control Display, for example
whether the runflat indicator is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Flat Tyre Monitor (RPA)"
The status is displayed.
Initialising
On initialisation, the current tyre pressures are
stored as a reference for detection of a flat tyre. The initialisation is started by confirming
the correct tyre inflation pressures.
When driving with snow chains fitted, do not
initialise the system.
On the Control Display:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Start the initialisation with "Perform reset".6.Drive off.
Initialising is completed while the vehicle is in
motion; this process can be interrupted at any
time.
Initialising resumes automatically when you
continue your journey.
Message of a flat tyre The yellow warning lamp is illuminated.
A Check Control message is shown.
There is a flat tyre or substantial loss of
tyre pressure.
1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System. If
all tyres are inflated to the correct pres‐
sures, the runflat indicator might not have
been initialised. In this case initialise the
system.3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
System limits
A natural, even loss of tyre pressurein all four
tyres that occurs over time is not detected.
Consequently, check the tyre inflation pres‐
sure at regular intervals.
No warning can be given in the event of sud‐
den tyre failure caused by external factors.
In the following situations, the system could be
slow to respond or operate incorrectly:
▷If the system has not been initialised.▷Journey on snow-covered or slippery sur‐
faces.Seite 109SecurityControls109

Park Assistant
Principle
The system supports you when parking in par‐
allel to the road.
Ultrasonic sensors measure parking spaces on
both sides of the vehicle.
The park assistant calculates the ideal parking
line and takes over steering during the process
of parking.
When parking up, also follow the visual and au‐
dible information and notes of the PDC, the
Park Assistant and the rear-view camera, and
respond accordingly.
The park assistant incorporates Park Distance
Control, PDC, see page 131.
Notes WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing the traffic situation. Due to limits of the sys‐
tem, it cannot respond independently in a rea‐
sonable way in all traffic conditions. Danger of
accidents. Adapt driving style to the driving
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.◀
ATTENTION
The Park Assistant may steer across
curbs or up onto curbs. Danger of damage to
property. Observe the traffic situation and in‐
tervene actively if the situation warrants it.◀
An engine stopped by the Auto Start Stop
function is automatically started by activating
the Park Assistant.Seite 139Driving comfortControls139

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.

Saving fuelVehicle 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.
General
Your vehicle contains wide-ranging technolo‐
gies for reducing consumption and emission
levels.
Fuel consumption depends on various factors.
A number of measures, such as a moderate
driving style and regular maintenance, can in‐
fluence fuel consumption and reduce burden
on environment.
Removing transported load that is not required
Extra weight increases fuel consumption.
Removing add-on parts after use
Remove auxiliary mirrors, roof racks and rear-
mounted racks after use.
Add-on parts on the vehicle interfere with its
aerodynamic performance and inflate fuel con‐
sumption.Closing windows and the
glass roof
An opened glass roof or opened window in‐
creases the drag coefficient and thus reduces
the range.
Tyres General Tyres can have differing effects on fuel con‐
sumption. For example, fuel consumption can
be affected by tyre size.
Checking tyre pressures regularly Check and, if necessary, correct tyre inflation
pressures at least twice a month and before
setting off on a longer journey.
Insufficient tyre inflation pressure enlarges the
rolling resistance and thus increases fuel con‐
sumption and tyre wear.
Setting off immediately Do not warm up the engine with the vehicle at
a standstill; it is preferable to set off straight
away, driving at moderate engine speeds.
This brings the cold engine to operating tem‐
perature as quickly as possible.
Driving with foresight
Avoid accelerating and braking unnecessarily.
Keep an appropriate distance from the preced‐
ing vehicle.
Anticipating the road situation and adopting a
smooth driving style will reduce fuel consump‐
tion.Seite 168Driving hintsSaving fuel168
