Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system.
Do not continue driving, but instead contact
your BMW center.<
Sports Wagon: self-leveling
suspension
Malfunction
The warning lamp for the self-leveling
suspension lights up in yellow and a
message appears on the Control Dis-
play. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possible also on one side – rear
left compared to rear right –, go to the nearest
BMW center or a workshop that works accord-
ing to BMW repair procedures with correspond-
ingly trained personnel. Drive with appropriate
caution in the meantime. The vehicle has
reduced ground clearance and driving comfort
may be noticeably reduced. Even if the position
of the vehicle is normal, go to the nearest BMW
center or a workshop that works according to
BMW repair procedures with correspondingly
trained personnel.
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.<

Technology for comfort, convenience and safety
88
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. When driving with snow
chains
* or with the compact wheel*, do not
initialize the system.<
iDrive, for principle details, refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.Select "FTM" and press the controller.
5.Start engine, but do not start driving.
6.Select "Set tire pressure" and press the
controller.7.Select "Yes" and press the controller.
8.Start to drive.
The message "Initializing..." is displayed.
The initialization finishes during driving. Then
the message "Status: FTM active" appears on
the Control Display again.
Indication of a flat tire
The warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact a BMW center.<
3.Replace the damaged wheel, refer to
Changing a wheel on page207.
Run-flat tires*
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 vehicle is not equipped with run-
flat tires, refer to page194, 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, luggage compartment or
cargo area full, or 4 persons without
luggage:
approx. 94 miles/150 km
>With a full load:
from 4 persons, luggage compartment
or cargo area full:
approx. 30 miles/50 km
Drive reservedly 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 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 your BMW
center.<
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 page85.
Malfunction
The warning lamp lights up and a mes-
sage appears on the Control Display.
The active steering is no longer opera-
tional. At low speeds, greater steering wheel
movements are required, whereas at higher
speeds, the vehicle reacts more sensitively to
steering wheel movements. The stability-
promoting intervention can also be deactivated.
Proceed cautiously and drive defensively. Have
the system checked.

Before transporting a child on the front
passenger seat, observe the safety infor-
mation and handling instructions under Trans-
porting children safely refer to page52.
The front and side airbag 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 airbag 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 airbag 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 airbag on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
The front and side airbag on the front pas-
senger side are not activated.
Operational readiness of airbag system
From radio readiness, refer to page56, 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.<

Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. Not all commercially available additives are
suitable for your BMW. Ask your BMW center
for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

Display of the previously described
malfunction on Canadian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. As BMW cannot
assess the suitability of other brake pads for
use on your vehicle, we are unable to assume
continued responsibility for the vehicle's oper-
ating safety if non-approved pads are
installed.<

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 speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring led to serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can close when
fuel vapor escapes. Then a display light 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
signed a contract of participation for BMW
Assist, certain vehicle data can be transmitted
or recorded to enable corresponding services.

car phone, no emergency calls can be made.
The car phone can be reactivated after signing a
new contract with a BMW center.
Initiating an emergency call
1.Briefly press protective cover to open.
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
2.Press the button for at least 2 seconds.
The LED in the button lights up. As soon as
the voice connection to the BMW Assist
emergency call center has been estab-
lished, the LED flashes.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.If the current location of your vehicle can be
determined, it will be forwarded to the
BMW Assist emergency call center.
If the LED flashes, but you are unable to hear
the BMW Assist emergency call center through
the hands-free system, this could indicate, for
instance, that the hands-free system is no
longer operational. However, you may then still
be audible for the emergency call center.
Under certain conditions, an emergency call is
automatically initiated immediately after a
severe accident. The automatic emergency call
is not affected by the button being pressed.
For technical reasons, the emergency call
cannot be guaranteed under unfavorable
conditions.<

wipers would not be available. If the vehicle
electrical system fails, do not tow-start or tow
the vehicle. The electric steering-wheel lock
cannot be unlocked and the vehicle cannot be
steered. For information on jump starting, refer to page212. There is no power assistance with
the engine stopped. This then requires
increased effort for braking and steering. Active
steering is deactivated and larger steering
wheel movements are required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.

tion switched on.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
