Cruise control*
The concept
The cruise control with a braking function is
available for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle stores and
maintains the speed that you set using the lever
mounted on the steering column. To keep the
specified speed constant, the system brakes if
the engine braking effect is not sufficient on a
downhill grade.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could lose control of the vehicle
and cause an accident.<

Maintaining current speed
Briefly press, arrow1, or briefly pull, arrow2
lever.
The speed currently being driven is stored and
maintained. It is indicated on the speedometer
and briefly in the instrument panel.
The controlled speed can drop on uphill grades
if the engine output is insufficient. If the engine
braking effect is not sufficient on a downhill
grade, the system lightly brakes the vehicle.
Increasing speed
Repeatedly press the lever up to or beyond the
resistance point, arrow1, until the desired
speed is set.
>Each time the lever is pressed to the resis-
tance point, the speed is increased by
approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed
increases by a maximum of 5 mph or
10 km/h.
The system stores the setting and maintains
the set speed.
Accelerating with lever
Accelerate slightly:
Press the lever up to the resistance point,
arrow1, until the desired speed is reached.
Accelerate more rapidly:
Press the lever beyond the resistance point,
arrow1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores the
setting and maintains the set speed.
Reducing speed
Repeatedly pull the lever up to the resistance
point or beyond, arrow2, until the desired
speed is displayed.
>Each time the lever is pulled up to the resis-
tance point, the desired speed decreases
by approx. 1 mph or 1 km/h.

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 page127.
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.

Technology for comfort, convenience and safety
86
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 the button until the DSC indicator lamp in
the instrument panel lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC are deactivated 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 controls the drive forces and
brake forces.
The indicator lamps light up:
DSC is 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 instrument panel display shows how xDrive
and Dynamic Performance Control are distrib-
uting the drive torque.Press the BC button on the turn signal lever
repeatedly until the display appears, refer to
arrow.
The drive train and wheels are schematically
depicted.
Bar graphs show the current distribution of
drive torque. The longer an illuminated bar is,
the greater the drive torque in the related wheel.
Malfunction
If xDrive and Dynamic Performance Control are
malfunctioning, the instrument panel display
appears in gray.
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

Technology for comfort, convenience and safety
88 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.
Activating HDC
Press the button; the LED lights up.
The HDC display is shown in the instrument
panel.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again. The LED and the HDC
display go out.
HDC is automatically deactivated at speeds
over approx. 37 mph/60 km/h.

HDC is temporarily unavailable in the following
situations due to a high brake temperature:
>The LED in the button and the display HDC
go out during HDC operation.
>The LED in the button and the HDC display
do not light up when the button is pressed.
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.

Malfunction
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. 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 possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activity Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
ably reduced. Even if the orientation of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
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.
