Malfunction
The warning lamp for the brake system
lights up in yellow. The drive-off assis-
tant has failed. The car will not be held
in place after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
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.<
The system could issue a false warning or func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>Driving on a snow-covered or slippery road
surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>Driving with snow chains attached
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is continued automatically
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine immediately before pulling
away, but do not drive off yet.
2.Press the button until the yellow indicator
lamp in the instrument cluster lights up for a
few seconds.
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.
Flat tire warning
The warning lamp in the instrument
cluster lights up in red. A signal also
sounds. There is a flat tire or a signifi-
cant loss of tire pressure.
1.Cautiously reduce speed to 50 mph/
80 km/h or lower. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page88, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the inflation pressure is correct in all
four tires, it is possible that the Flat
Tire Monitor was not initialized. In this case,
initialize the system.<

Technology for driving comfort and safety
54 3.In the event of complete tire pressure loss,
0 psi/0 kilopascal, 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 bay full,
or
2 persons without luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously. Do not exceed a speed
of 50 mph/80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes reduced tracking stability in brak-
ing, extended braking distance and altered nat-
ural 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 to the side of the road at the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact a BMW center.<
Tire Pressure Monitor TPM*
The concept
TPM monitors the tire inflation pressure in all
four mounted tires. The system reports if infla-
tion pressure has dropped significantly in one
or more of the tires.
System requirements
To ensure a reliable flat tire warning, the system
must have been reset while tire inflation pres-
sures were correct.
Always use tires with TPM electronics to
ensure that the system operates properly.The system must be reset each time a tire
inflation pressure has been corrected or a
wheel or tire has been changed.<
System limitations
TPM cannot report sudden serious tire
damage due to external causes.<
The system will not operate correctly if it was
not reset, e.g. it may report a flat tire even if the
tire inflation pressures are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics is
mounted or if other systems or devices that use
the same radio frequency temporarily interfere
with the TPM system.
Resetting the system
The system must be reset each time a tire
inflation pressure has been corrected or a
wheel or tire has been changed.<
1.Start the engine but do not drive off yet.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Drive off.
After several minutes of driving, the current
inflation pressures in the tires are adopted
as the target values to be monitored. The
resetting procedure is completed automat-
ically without further notice during the trip,
which can be interrupted at any time.
Resetting is continued automatically when
you continue driving.

Warning of low tire inflation pressure
The warning lamp lights up in yellow. A
signal also sounds. There is a flat tire or
a significant loss of tire pressure in one
or more tires.
1.Cautiously reduce speed to 50 mph/
80 km/h or lower. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, which is the standard
equipment by design, refer to page88, then
do not continue driving. Doing so after a tire
puncture may result in a severe accident.<
2.In the event of complete tire pressure loss,
0 psi/0 kilopascal, you can estimate how far
you can continue 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 bay full,
or
2 persons without luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously. Do not exceed a speed
of 50 mph/80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes reduced tracking stability in brak-
ing, extended braking distance and altered nat-
ural 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 to the side of the road at a
suitable location at the earliest opportunity.
Otherwise, parts of the tire could come loose
and cause an accident. Do not continue driving.
Contact a BMW center.<
Malfunction
The yellow warning lamp flashes and
then lights up continuously. A flat tire
cannot be detected.
This warning is displayed under the following
circumstances:
>If there is a malfunction;
have the system checked.
>If a wheel without TPM electronics is
mounted.
>If other systems or devices that use the
same radio frequency temporarily interfere
with the TPM.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
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.
Under-inflation 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 under-
inflation has not reached the level to trigger illu-
mination 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

Technology for driving comfort and safety
56 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.
Electric Power Steering EPS
The concept
The electric power steering is a direct, sporting
steering system. A special combination of elec-
tric motor and transmission helps you steer
more easily. As your speed increases, steering
power assistance is reduced.
Malfunction
The indicator lamp stays lit:
The system is malfunctioning or defec-
tive.
Steering remains operational.
Have the system checked as soon as possible.
Brake Force Display
Left: normal braking.
Right: hard braking.
Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Side airbags
3Knee airbags
Protective action
Comply with the instructions on page30,
or the occupants' personal safety will be
diminished.<
The front airbags help protect the driver and
passenger in the event of a frontal impact in
which safety belts alone cannot provide suffi-
cient protection. When needed, the side airbags
help provide protection in the event of side
impact. The relevant side airbag supports the
side upper body area. The respective knee air-
bag protects the legs from hitting the cockpit.
The airbags will purposely not be activated by
every collision, e.g. not by more minor acci-
dents, 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. Do not attempt to
dismantle the airbag retention system. Do not
modify the individual components of the sys-
tem or its wiring in any way. This includes the
padding in the steering wheel, the dashboard
and the doors.
Do not attempt to remove or dismantle the
steering wheel. Do not touch the individual
components immediately after the system has
been triggered, because there is a danger of
burns.
