Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. 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 system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period
of time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<1."Vehicle Info"

6.Start to drive.
The initialization is completed during the trip.
The initialization is completed during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with run-flat
tires, refer to page199, the standard
equipment by design, do not continue driv-
ing. Otherwise, a severe accident could
result if you continue driving.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<

Technology for driving comfort and safety
82 3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, cargo area full, or 2 people
without luggage:
approx. 90 miles/150 km
>With a full load:
2 people, cargo area full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h; otherwise,
there is a risk of an accident. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherwise, parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.<

Tire Pressure Monitor TPM*
The concept
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.

FMVSS 138
Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
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 lit. This sequence will continue
upon subsequent vehicle 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 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.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels depending on the
speed at which you are driving. When you are
driving at low speeds, power steering provides
more support, i. e. little effort is needed to turn
the wheels. Power steering support lessens as
your speed increases.
The system works automatically.
Malfunction
Malfunctions are displayed via Check Control.
Dynamic brake lamps*
On the left: normal braking.
On the right: sharp braking.
During sharp braking, the brake lamps and the
dynamic brake lamps of your BMW light up.
The dynamic brake lamps are automatically
activated if the turn signal is not flashing.
Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Side airbags in the seat backrests
3Knee airbag
Protective action
Observe the adjustment instructions on
page41 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade-
quate restraint. When needed, the side airbags
help provide protection in the event of a side
impact. The relevant side airbag supports the
head and the side upper body area.
The airbags have been designed to not be trig-
gered in every collision situation, e.g., not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and window on the pas-
senger side clear, i.e., do not cover with adhe-
sive labels or coverings, and do not attach hold-
ers such as for navigation instruments and
mobile phones.
Do not attach seat covers, cushions or other
objects to the front seats that are not specifi-
cally approved for seats with integral side air-
bags. Do not hang items of clothing such as
coats or jackets over the backrests.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-

Technology for driving comfort and safety
86 vidual components of the system or its wiring in
any way. This includes the upholstered covers
of the steering wheel, the dashboard and the
seats. Do not attempt to remove or dismantle
the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the passenger
seat is occupied by measuring the resistance of
the human body. Front, knee and side airbags
on the passenger side are activated or deacti-
vated accordingly.
Make sure that the passenger keeps his
or her feet in the footwell; otherwise, the
passenger airbags may not function properly.<
The indicator lamp above the interior rearview
mirror shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, see page48.
Malfunction of the automatic
deactivation system
The front, knee and side airbags can also be
deactivated by adolescents and adults sitting in
certain positions; the indicator lamp for the pas-
senger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, do not transport
the passenger in the vehicle.
To make sure that occupation of the seat cush-
ion can be detected correctly:
>Do not attach seat covers, seat cushion
padding, ball mats or other items to the pas-
senger seat unless they are specifically rec-
ommended by BMW.
>Do not place any items under the seat which
could press against the seat from below.<
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
>The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is
detected on the seat or the seat is empty.
The front, knee and side airbags for the pas-
senger are not activated.

. Intermediate settings are pos-
sible. In the 6 o'clock position, a small amount
of air is also directed towards the windows in
order to keep them from fogging over.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the interior of the car
temporarily. The system then recirculates the
air currently within the vehicle.
You can also activate/deactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page11.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
continuously for lengthy periods; otherwise, the
quality of the air inside the car will gradually
deteriorate.<
Air flow rate
Press the corresponding button.
The higher the rate, the more
effective the heating or cooling
will be.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power.
Switching the system on/off
With the blower at its lowest set-
ting, press the left side of the but-
ton. The blower and air conditioner
are completely switched off and the air supply is
cut off.
To switch on the air conditioner, set the desired
air flow rate.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required, according to the
temperature setting. This function is only avail-
able while the engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
