Indication of a flat tire
The warning lamp lights up 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.
If you have deactivated DSC, it will be activated
automatically.
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.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.If the vehicle is not equipped with run-
flat tires as provided at the factory,
refer to page239, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
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 guide values:
>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
speeds of 50 mph/80 km/h or else you
run the risk of causing 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 vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
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 the BMW
Sports Activity Vehicle Center.<

Technology for comfort, convenience and safety
96 A message like this is displayed in the following
situations:
>In case of a malfunction:
Have the system checked
>If a wheel without TPM electronics is
mounted, e.g. a compact wheel
*
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency
Explanation according to the 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 underinflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping 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 actively varies the steering
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies
the steering force required for steering depend-
ing on the vehicle's speed.
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.
Malfunction
The warning lamp lights up yellow
and a message is shown on the Con-
trol Display. The active steering is no
longer operational. At low speeds,
greater steering wheel movements are
required, whereas at higher speeds, the vehicle
reacts more sensitively to steering wheel move-
ments. The stability-promoting intervention
can also be deactivated. Proceed cautiously
and drive defensively. Have the system
checked.

Technology for comfort, convenience and safety
98 Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Otherwise
unprofessional attempts to service the system
could lead to failure in an emergency or undes-
ired airbag triggering, 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, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page55.
When teenagers and adults assume certain sit-
ting positions, this can cause the front and side
airbags to deactivate. The indicator lamp for the
front passenger airbags lights up when this
occurs. In these cases, change the sitting posi-
tion so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically 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.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehi-
cle is manufactured. After installing a child's
seat, make sure that the indicator lamp for
the front passenger airbags lights up. This
indicates that the child's seat has been
detected and the front passenger airbags
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.

Weather Radio is a service of the National Oce-
anic and Atmospheric Administration (NOAA)
of the US Department of Trade. Weather news
flashes are repeated every four to six minutes
and are routinely updated at intervals of one to
three hours, and more often when necessary.
Most stations operate 24 hours a day. In case of
a storm, the National Weather Service inter-
rupts the routine weather news and transmits
special warning messages instead. If you have a
question about NOAA Weather Radio, please
contact the nearest office of the National Weather Service. Details are also provided on
the Internet at www.nws.noaa.gov.

drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page75. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/liter of oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come into
contact with oil should be thoroughly washed
with soap and water.
Keep oil, grease etc. out of reach of children and
observe the warnings on the containers to pre-
vent health risks.<
Oil change
Only have an oil change carried out by a BMW
Sports Activity Vehicle Center or a workshop
that works in accordance with BMW guidelines
and uses appropriately trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives, as these may
result in engine damage.<
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Only
use oils of the specification API SM or higher.

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up.
The exhaust-gas values worsen.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce your speed and
proceed to the nearest BMW Sports Activity
Vehicle Center. Heavy engine misfiring causes
serious damage to the emission-relevant com-
ponents, especially the catalytic converter,
within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can
be transmitted or recorded to enable corre-
sponding services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
