92 rupted at any time. When driving resumes, the
reset is continued automatically. On the Control
Display, the tires are shown in green and "Sta-
tus: TPM active" is displayed again.
If a flat tire is detected while the system is
resetting and determining the inflation
pressures, all tires on the Control Display are
displayed in yellow. The message "Tire low!" is
shown.<
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds. There is a flat tire or substan-
tial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page219, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture if you continue
driving.<
2.In the event of complete 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 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or 4 persons
without luggage:
approx. 95 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h. 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.<
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. On the Control Display,
the tires are shown in gray and a message
appears. No punctures can be detected.
his type of message is shown in the following
situations:
>If there is a malfunction
Have the system checked.
>If a wheel without TPM electronics has
been mounted
>If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.
Message for unsuccessful system
reset
The warning lamp lights up yellow. A
message will appear on the Control
Display. The system is not reset after
a tire has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page91.
Declaration according to NHTSA/
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

The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indicator lamp for the front
passenger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the front passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise a correct analysis of the seat cushion is not
ensured.<
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger's front and side airbags in accor-
dance with whether and how the front passen-
ger seat is occupied. The indicator lamp shows
whether the front passenger airbags are acti-
vated or deactivated.
>The indicator lamp lights up when a child in
a specially designated child-restraint sys-
tem is detected, as intended, on the seat.
The front and side airbags for the front pas-
senger are not activated.
Most child seats are detected by the
system, especially child seats
required by the NHTSA at the time of vehi-
cle production. After mounting a child seat,
ensure that the indicator lamp for the front
passenger airbag is lit. It indicates that the child seat has been detected and that the
front passenger airbags are deactivated.
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat.
The front and side airbags for the front pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty.
The front and side airbags for the front pas-
senger are not activated.
Operational readiness of airbag system
As of radio readiness, refer to page56, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
>Warning lamp does not light up at radio
readiness or beyond.
>Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay, otherwise
there is the risk that the system will not function
as intended even if a sufficiently severe acci-
dent occurs.<

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
Run-Flat Tires. A flat tire will seriously impair
your vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting tire inflation pressures,
always reinitialize the Flat Tire Monitor,
refer to page89.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:
>Tire sizes for your vehicle>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100mph or 160km/h.
These tire inflation pressures can also be found
on the driver's-side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed, otherwise
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise tire
damage and accidents could occur.<
Observe all national and local maximum speed
limits, otherwise violations of the laws could
occur.
