Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected 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 snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or com-
pact wheel

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, e.g. a compact wheel, 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.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems or
devices which use the same radio fre-
quency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving, which can be
interrupted at any time. When driving resumes,
resetting is continued automatically.Do not
reset the system when driving with a compact
wheel

stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<
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 wheel 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 telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale 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. Under-
inflation 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 under-inflation has
not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale 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 function
properly.Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page88.

or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, observe the safety infor-
mation and handling instructions under Trans-
porting children safely refer to page55.
The front and side airbags on the front passen-
ger side can be deactivated for teenagers and
adults in certain seat positions; then the indica-
tor lamp for the front passenger airbags lights
up. In these cases, change the seat position so
that the front passenger airbags are activated
and the indicator lamp goes out. If the desired
status cannot be produced by changing the
seat position, transport the corresponding per-
son on the rear seat. Do not fit seat covers, seat
cushion padding, ball mats or other items onto
the front passenger seat unless they are specif-
ically recommended by BMW. Do not lay
objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front and side airbags on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.

Operational readiness of airbag system
From radio readiness, refer to page59, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction, otherwise
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<

>Sunglasses with certain polarization filters
>Certain seating positions
>Objects on the cover of the Head-Up Dis-
play
>Wet road surface and unfavorable lighting
conditions
If the image is distorted, please have the basic
setting checked at a BMW center.
Special windshield
The windshield is part of the system. The shape
of the windshield complies with the require-
ments of the Head-Up Display to enable a pre-
cise display. A film in the windshield prevents
the double images from being displayed.
Windshield replacement should be carried out
by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.

BMW Night Vision's potential benefits
can be limited by the driving style of the
driver, the size and relative temperature of the
detected objects, dirt or contamination on the
camera lens, adverse weather like snow, rain or
fog, and other factors not mentioned here. It will
always be the driver's responsibility to drive at a
speed and in a manner that recognizes potential
hazards and adjust accordingly.
BMW Night Vision is not a substitute or replace-
ment for driver responsibility or for accommo-
dating the visibility conditions and the traffic sit-
uation. The forward view illuminated by the
headlamps must always be the basis for making
safe driving decisions, otherwise a safety risk
will result.<
Activating BMW Night Vision
1.Turn the light switch to position2 or3, refer
to page103.
2.With low beams switched on:
>Press the button. Depending on the
vehicle's equipment, the location of the
button may differ somewhat.
>Press one of the programmable buttons
on the steering wheel, refer to page53.
The image will be displayed on the Control Dis-
play after a few seconds. Depending on the last
mode selected, either the normal or full screen
image will be displayed.Due to the system's need to adjust periodically,
a still image is displayed at certain intervals for
fractions of a second. This is normal and not an
indication of a problem.
To prevent driving without headlamps, at a
speed of more than approx. 3 mph/5 km/h and
when dark, the thermal image on the Control
Display is only shown when the low beams are
on.

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is preferable to
switch on the roadside parking lamps on one
side, refer to page105.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
If the light switch remains in position 2, the
exterior lamps are switched off automatically
when the driver's door is opened while the igni-
tion is off.
Switch on the parking lamps if required as
described under Parking lamps.
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.
When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
If desired, the light switch can be left in posi-
tion3. The exterior lamps are automatically
switched off after switching off the vehicle.
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.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.
