one attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
five minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming the alarm
system
When you lock or unlock the vehicle, either
with the remote control unit or at the door
lock, the alarm system is armed or dis-
armed at the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can also open the luggage compart-
ment lid with the system armed using
button 3 on the remote control, refer to
page 34. When you close the lid, the sys-
tem is rearmed.
Pressing the Panic mode button for a
longer period triggers the alarm, refer
to page 34.<
To deactivate the alarm
>unlock the vehicle using the remote
control, refer to page 34
>insert the remote control all the way into
the ignition lock, engaging the detent.
Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes when the
system is armed: door(s), the hood or
luggage compartment lid are not com-
pletely closed. Even if you do not close
the alerted area, the system begins to
monitor the remaining areas, and the
indicator lamp flashes continuously
after 10 seconds. However, the interior
motion sensor is not activated
>The indicator lamp goes out when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the system
was armed
>The indicator lamp flashes when you
disarm the system before the remote
control unit is inserted in the ignition
lock, but for no more than roughly
5 minutes: an attempted entry has been
detected in the period since the system
was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered in garages with
elevator ramps, for instance, or when the
vehicle is transported by trailer or train:
Lock, i.e. arm twice; press button 2
on the remote control twice in succession,

Releasing
1.Press the red button in the belt buckle
2.Hold the belt firmly
3.Guide the belt back into its reel.
The shoulder strap's anchorage point will
be in the correct position for seat occu-
pants of every build if the seat is correctly
adjusted, refer to page 44.
The two rear safety belt buckles integrated
in the rear seat are for passengers sitting
on the left and right. The belt buckle
embossed with the word CENTER is
intended exclusively for use by passengers
riding in the center position.
Damage to safety belts
If the safety belts are damaged or
stretched in an accident: have the
entire belt system, including the tensioning
mechanisms, replaced at your BMW cen-
ter. Have the belt anchorage points
inspected for damage at the same time.
Failure to observe this precaution may pre-
vent the safety belts from effectively pro-
viding optimal protection when needed.<
Rear seats
When the rear center position is not
occupied, the latch on the safety belt
can be inserted in the slot between the
seat's upholstery and the backrest.<
Seat heating*
Front
The system regulates the temperatures of
the seat cushion and backrest.

Driving
74 In addition to holding a steady cruising
speed, if you do encounter slower vehicles
ahead, active cruise control will Ð within the
scope of given possibilities Ð adjust your
vehicle's speed automatically so that one
can flow with the traffic without frequent
intervention by the driver. If, for example,
while cruising at the selected speed, you
begin to approach a slower vehicle ahead
of you in the same lane, the system will
reduce your vehicle's speed to the same as
that of the vehicle ahead to maintain your
selected distance setting between your
vehicle and the vehicle ahead. There are
four settings for distance, which is addi-
tionally speed-dependent. Based on your
selected distance setting, the system auto-
matically decreases the throttle setting and
lightly applies the brakes if necessary.
The vehicle brake lamps will automatically
illuminate to signal a following driver to
take action. In addition, it may be neces-
sary for the vehicle to downshift to maintain
the distance setting selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehicle will accelerate
to the speed you have selected by increas-
ing the throttle setting and shifting gears as
needed.
Active cruise control is not and must
not be used as a collision avoidance/
warning system.<
Since this active cruise control sys-
tem is a new technology and operates
differently from conventional cruise control
systems which you may be accustomed to,
you are strongly urged to read all of the
pages relating to this system before use.
Pay special attention to the information
contained in the Things to know about
active cruise control section in this manual
beginning on page 77.<

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones indicate the current distance
to an object behind or in front of your vehi-
cle. Four ultrasonic sensors in both the
bumpers monitor the distance to the near-
est object. The sensors at the front and at
the two rear corners have a range of
approx. 2 ft/60 cm; the rear middle sensors
have approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic function
Whenever the ignition is on the system
automatically assumes operational status
after a few seconds each time you engage
the transmission position R.
Wait this short period before revers-
ing.<
Manual activation
Press the button, the indicator lamp lights
up.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Automatic deactivation
The system is automatically deactivated
once the vehicle travels approx. 165 ft/
50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become
shorter. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a status message appears in
the Check Control.
Please take note of the additional informa-
tion on the Control Display.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center.

PDC with visual warning
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm. This activates the PDC dis-
play.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically
reappears after the system is deactivated.
Confirming the menu item takes
you back to the previous display.<
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars and trailer couplings, as well as thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control/
ABS Antilock Brake System
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
In case of malfunction
If the indicator lamp lights up in
yellow, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.

Technology for comfort, convenience and safety

In case of malfunction
If the brake system warning lamp
lights up in red, together with the
yellow indicator lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems. The electronic brake-
force distribution is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.

Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
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 includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
Indicator lamps
The indicator lamp in the Info Dis-
play goes out soon after you start
the engine.
If 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.
The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

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.

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.
In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display.
You can find more information on the
Check Control starting on page 82.
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
minimum, 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 program
The Comfort program 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.

Parking lamps
With the switch in this position, 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 fea-
ture, refer to page 100.
Low beams
When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.
Pathway lighting:
After parking the vehicle and switch-
ing off the headlamps, you can use the
headlamp flasher control to activate
the low beams for a period of roughly
40 seconds. You also have the options of
extending this period or, as an alternative,
having this function deactivated.<
Lights on warning
If you switch off the ignition while the head-
lamps are on, when you subsequently open
the driver's door a gong will sound for sev-
eral seconds, while the Check Control will
provide you with a message
.
Daytime driving lamps*
If you wish, you can leave the light switch in
the low-beam position. Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
You can have the daytime driving
lamps on your vehicle programmed to
operate as desired.<
Automatic headlamp control
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in tunnels, at dawn
and dusk, and in rain and snow. The green
indicator lamp next to the symbol is illumi-
nated when the low beams are on.
Following automatic activation, the
vehicle's external lighting remains on
when you switch on the fog lamps.<
The automatic headlamp control can-
not serve as a substitute for your per-
sonal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For exam-
ple, the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
You can have the sensitivity of the
headlamp control system adjusted on
your vehicle.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumi-
nation of the road surface. Depending on
the steering angle and other assumptions,
the light from the headlamp follows the
course of the road.
