EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
DSC Dynamic Stability Control
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimized
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC contains the functions
DTC Dynamic Traction Control and DBC
Dynamic Brake Control.
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
Activating DTC Dynamic Traction
Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now activated.
The DTC indicator lamp in the Info Display
lights up permanently.
When DTC is active, DSC provides
only limited system response up to a
speed of approximately 45 mph/70 km/h.
Intervention for stability enhancement is
reduced.<
Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now deacti-
vated. The DTC indicator lamp in the Info
Display goes out. DSC is once again avail-
able without restriction.

malfunction on Canadian models.
Dynamic Drive
The concept
Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.
Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-
oriented when the vehicle is proceeding in
a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
Malfunction
The warning lamp lights up, accom-
panied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display. A malfunction has occurred in the
system. Have the system checked as soon
as possible.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a Check Control message stating that you
should stop appears in addition to the red
symbol, stop immediately and switch off
the engine. In this case the oil level in the
reservoir may have dropped below the min-imum, possibly owing to a leak in the
hydraulic system.
Please observe the additional instructions
provided on the Control Display.<
EDC Electronic Damping
Control*
The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.
Two programs are available; they can be
selected in the "Settings" menu.
Comfort mode
The Comfort mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load.
Sport program
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and steer-
ing.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure another
tire.

Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do not
exceed a vehicle speed of 50 mph/80
km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page206.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page206.
Malfunction
The indicator lamp lights up yellow,
accompanied by a status message
in the Check Control. The Flat Tire
Monitor has malfunctioned or failed. Have
the system checked as soon as possible.
Self-leveling suspension*
Malfunction
A Check Control message appear-
ing together with this symbol indi-
cates a malfunction in the self-level-
ing suspension. Please take note of the
additional information on the Control Dis-
play.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, please respond by immediately
proceeding to the nearest BMW center.
Drive with appropriate caution in the mean-
time. The vehicle has reduced ground
clearance and driving comfort may be
noticeably reduced. Even if the attitude of
the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
Brake Force Display
The Brake Force Display indicates the
intensity with which you are applying your
brakes to drivers of following vehicles.
The display consists of two stages:
>Normal braking:
The brake lamps in the tail lamp assem-
blies and the high-mount brake lamp on
the rear tray light up during braking
>Heavy braking and braking with ABS:
The rear lamps also light up with the
same intensity as the standard brake
lamp units to enhance the warning
effect of the brake lamps.

child in the child-restraint system or an
adult.
>When a child is seated in the child-
restraint system or with an empty seat,
the front and side airbags are automat-
ically deactivated on the passenger's
side
>When an adult is traveling in the front
seat, the front and side airbags remain
active on the passenger side.
Although not desired, it can occur in
the case of heavier children that the
front passenger airbags remain active or in
the case of very light adults or young per-
sons that the front passenger airbags are
deactivated.
The state of the front passenger airbags is
shown with the indicator lamp, refer to Indi-
cator lamps in the following. In this case
transport the corresponding persons on the
rear seat.
Except when persons to be transported, do
not increase the load on the front passen-
ger seat with additional items. Do not fit
seat covers, seat cushion padding, ball
mats or other items to the front passenger
seat unless they are specifically recom-
mended by BMW. Do not place any items
under the seat. Otherwise, the function of
the seat occupation detection could be
impaired.<

Temperature adjustment
You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains this
temperature, regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection rep-
resented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic air
supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and
starts to provide maximum air supply through the vent outlets only. For this rea-
son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/recirculated
air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is permanently blocked. The
system then recirculates the air cur-
rently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle
is stopped at a school to pick
up a child.
You can adjust the automatic climate con-
trol's settings when the ignition lock is in
the radio mode. The system blows heated
