The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<

DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
For better control
The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp lights up:
DTC is activated.
xDrive on 525xi, 530xi
xDrive is the 4-wheel drive system of your
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.

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.<

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page43.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents, certain roll-over conditions, or rear-end
collisions.
Stickers on the rear door frame indicate
the status of the rear side airbags. If the
status cannot be clearly recognized, or if you
want to have the airbags activated/deactivated,
please contact your BMW center.<
For details on the correct seat position, refer to
page43.
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
remove the airbag retention system from the
vehicle. Do not modify or tamper with either the wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the doors and the roof pillars
along with the sides of the headliner. Do not
attempt to remove or dismantle the steering
wheel. Do not touch the individual components
immediately after the system has been trig-
gered, because there is a danger of burns. In the
event of malfunctions, deactivation, or trigger-
ing of the airbag restraint system, have the test-
ing, repair, removal, and disposal of airbag gen-
erators executed only by a BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, 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 airbag on the front passenger side are acti-
vated or deactivated accordingly by the system.
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, 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.<

In switch position2, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page95.
The parking lamps drain the battery. Do
not switch them on for long periods of
time, otherwise it may no longer be possible to
start the engine.<
Low beams
The low beams are activated in switch posi-
tion 3 with the ignition switched on, otherwise
only the parking lamps are switched on.
Pathway lighting
When you activate the headlamp flasher after

and switches on and off the low beams in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.
When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.

The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.
With the daytime driving lamps
* activated, the
low beams are always switched on when the
ignition is switched on.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In the switch position1, the Adaptive Head
Light is active and the automatic headlamp con-
trol
* is switched on.
To avoid dazzling oncoming traffic, the Adap-
tive Head Light is not active when driving in
reverse and points toward the passenger side
when the vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not switch them on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the inside rearview mirror controls the process.
The assistant ensures that the high beams are
switched on whenever the traffic situation
allows. This reduces the strain on you while at
the same time providing you with the best pos-
sible visibility. Of course, you can intervene at
any time and switch the high beams on and off
in the accustomed manner.

mum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system then recircu-
lates the air currently within the vehicle. During
AUC operation, a sensor detects pollutants in
the outside air and controls the shut-off auto-
matically.
By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Left LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
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 volume as
required.
The recirculated-air mode should not be used
over an extended period of time, as the air qual-
ity inside the vehicle deteriorates continu-
ously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/
256The LED lights up when the function is
switched on.
