The system requests that the you
intervene by braking and carrying
out evasive maneuvers, if neces-
sary. The system cannot independently restore
the distance to the vehicle ahead.
This display does not relieve the driver of the
responsibility to adapt his or her desired driving
speed and style to the traffic conditions.

the system is interrupted and the distance indi-
cator goes out until the pedal is fully released.
As soon as you fully release the accelerator, the
system will again control your cruising speed
and distance setting. While driving with the sys-
tem activated, resting your foot on the acceler-
ator pedal will cause the system not to brake
even if necessary. Be certain that floor mats or
other objects on the vehicle floor do not inter-
fere with movement of the accelerator pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e. g.
when you reduce your desired speed sharply. It
uses only a portion of braking system capacity
and does not utilize the full capacity of the vehi-
cle braking system. Therefore, the system can-
not decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range.<

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 page140.
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.

Technology for comfort, convenience and safety
96 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.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button: the indicator lamp in the
instrument panel goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp lights up:
DSC and DTC are malfunctioning.
DSC deactivated:
The indicator lamp lights up and
DSC OFF appears in the instrument
panel.DSC and DTC deactivated.
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.
1."Vehicle Info"
2."Torque distribution"
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 page82.
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

Technology for comfort, convenience and safety
98 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. 3 mph/4 km/h. Pull the
lever of the cruise control beyond the resis-
tance point, arrow3.
1Increasing speed
2Pull to the resistance point:
Reduce speed to approx. 4 mph/6 km/h
3Pull beyond the resistance point:
With downhill grade over 10Ξ, reduce
speed to approx. 3 mph/4 km/h.

Malfunction of driving stability control
systems
When driving on poor roads, avoid using
full throttle or pressing the accelerator
beyond the kickdown point and also avoid
heavy braking. Otherwise, the drive train may be
damaged or accidents can occur.<

The comfortable basic setting offers opti-
mum comfort when traveling.
>Sport:
The sporty basic setting offers increased
driving agility.

Drive-off assistant
The drive-off assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.1.Hold the vehicle with the brake pedal.
2.Release the brake pedal and immediately
drive off quickly.
The drive-off assistant holds the vehicle
for approx. 2 seconds after releasing the
brake pedal. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the brake pedal, immediately
start quickly, otherwise the drive-off 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 page82.
FTM Flat Tire Monitor*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
