Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc.
The shorter the distance to the object
becomes, the shorter the intervals become.
If the distance to the nearest object falls to
below roughly 1 ft/30 cm, then a continuous
tone sounds.
If objects are present both in front of and behind
the vehicle, then an alternating, continuous
tone sounds.
An intermittent tone is interrupted after approx.
3seconds:
>when the vehicle remains stationary in front
of an object that has only been detected by
one of the corner sensors
>when driving parallel to a wallThe signal tone is switched off:
>when the vehicle is more than approx.
4.0 in/10 cm away from an object
>when the selector lever is in the P position
Volume
You can adjust the volume of the signal tone,
refer to page81.

Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page132.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style remains the responsibility of the driver.
Therefore, do not restrict the additional safety
margin with a risky driving style, as otherwise
there is a risk of an accident.<
Deactivating DSC
Press and hold the button until the indicator
lamp for DSC lights up and DSC OFF appears in
the instrument panel, but do not press the but-
ton for longer than approx. 10 seconds. DTC
Dynamic Traction Control and DSC are deacti-
vated together. Stabilizing interventions are
now not carried out.

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 in sand, 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, sand or on loose
ground
>When driving with snow chains

xDrive
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 forces to
the front and rear axle depending on the driving
situation and prevailing road conditions.
Dynamic Performance Control*
The concept
Dynamic Performance Control optimizes the
handling characteristics of your BMW when
starting off, cornering, and during evasive
maneuvers. To achieve this, the system variably
distributes the drive torque of the rear axle to
the two rear wheels. This further increases the
steering precision and tracking stability of your
vehicle.
Display
The Control Display shows how xDrive and
Dynamic Performance Control are distributing
the drive forces.
Press the BC button in the turn signal lever,
refer to page73, until the display appears.
The current distribution of drive forces is indi-
cated by arrows pointing to all four wheels.
The highlighted arrows show the drive forces
currently present. The longer an arrow is, the
greater the drive forces in the associated wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.
Malfunction
Malfunctions are displayed via Check Control,
refer to page77.
HDC Hill Descent Control
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately walking speed without active
intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately walking
speed, approx. 5 mph/8 km/h, and then main-
tains this speed at a constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 4 mph/6 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.
With downhill grade over 10Ξ you can reduce
the speed to approx. 3mph/4km/h. Pull the
lever of the cruise control beyond the resis-
tance point, arrow3.

Malfunction of driving stability control
systems
When driving on poor roads, avoid using
full throttle or pressing the accelerator
beyond the kick-down point and also avoid
heavy braking. Otherwise, the drive train may be
damaged or accidents can occur.<
Adaptive Drive*
The concept
Adaptive Drive reduces the body roll which
occurs when cornering quickly or during fast
evasive maneuvers. In addition, Adaptive Drive
reduces the steering angle requirement,
improves the running comfort and increases
the dynamic driving characteristics of your
BMW.
Chassis and suspension tuning
You can choose between two types of chassis
and suspension tuning.
>Normal:
The comfortable basic setting offers opti-
mum comfort when traveling.
>Sport:
The sporty basic setting offers increased
driving agility.

Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and immediately
drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the footbrake, immediately start
quickly, otherwise the starting assistant no
longer holds the vehicle after approx. 2 seconds
and it begins to roll back.<
Self-leveling suspension*
The concept
The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, e.g. due to loading of the vehicle, then
this difference is compensated for very quickly.
In addition, spring motions resulting from cor-
nering or irregularities in the road surface are
reduced to a minimum.
The system functions automatically.
Malfunctions
Malfunctions are displayed via Check Control,
refer to page77.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Function requirements
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.<
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.<
