FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate sudden
severe tire damage caused by outside factors
and does not detect a natural, even pressure
drop in all four tires.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire. To do this, check the
tire inflation pressure using the M Mobility
System, refer to Producing tire inflation
pressure on page219.3.Repair flat tire with M Mobility System, refer
to page218, or replace the damaged wheel,
refer to Changing wheels on page220.
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.

The spare tire
* is equipped with the necessary
TPC electronics and is also monitored after
mounting and after resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheels is mounted without TPM elec-
tronics.
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare*, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire pressure monitoring system, TPMS, that illumi-
nates a low tire pressure indicator when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure indicator illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability. Please note that the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has
not reached the level to trigger illumination of
the TPMS low tire pressure indicator.
The TPMS malfunction indicator is combined
with the low tire pressure indicator. When the
system detects a malfunction, the indicator will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to func-
tion properly.

side, refer to page98.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
In switch position3, the system activates the
low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.
You can activate the daytime running lamps,
refer to page97. In the situations named above,
the system then automatically switches over to
the low beams.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
low beams manually under these conditions.<

Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Do not use the driving programs 5 and 6, refer
to Drivelogic on page63, during break-in.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 5,500 rpm or 105 mph/
170 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km to
3,000 miles/5,000 km
The engine and driving speeds can gradually be
increased up to a continuous vehicle speed of
135 mph/220 km/h. Only drive at top speed
briefly, e.g. when passing.
Transmission
The function of the transmission is only at its
optimized level after driving a distance of
approx. 300 miles/500 km. Do not exceed
engine speeds of 5,500 rpm during this time.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. With manual transmission:
During this break-in period, engage the clutch
gently.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
General driving notes
Ground clearance
Ensure that sufficient ground clearance
is available. To drive down curbs, select
the "Sport" program of the EDC Electronic
Damping Control, refer to page85, to keep the
ground clearance as uniform as possible. Oth-
erwise, the vehicle may be damaged.<
Closing luggage compartment lid
Only drive with the luggage compartment
lid completely closed, otherwise exhaust
can penetrate into the passenger compart-
ment.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Coupe: close both windows.
Convertible: with closed top, close all win-
dows.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page103.
