Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.

The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without the brakes being applied,
the vehicle moves at slightly more than twice
walking speed.
Hill Descent Control can be activated at speeds
below approx. 22 mph/35 km/h. When driving
downhill, the vehicle reduces its speed to ap‐
prox. twice walking speed and then keeps its
speed constant.
As long as there is active braking, the system is
on standby. The system does not brake the ve‐
hicle during this time.
Use HDC in low gears or in transmission position
D or R only.
Increasing or decreasing vehicle speed
Specify desired speed in the range from approx.
4 mph/6 km/h to approx. 15 mph/25 km/h using
the rocker switch of the cruise control on the
steering wheel. Vehicle speed can be changed
by lightly accelerating.▷Press up the rocker switch to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.▷Press down the rocker switch to the point of
resistance: the speed decreases gradually.▷Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.

A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Adaptive Drive
The concept
Adaptive Drive includes the following systems:
▷Dynamic Drive, refer to page 109▷Dynamic Damping Control, refer to
page 109
The system increases driving stability and driv‐
ing comfort.
Dynamic Drive
The concept
Dynamic Drive reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased under all driving conditions. The system
utilizes active stabilizer bars on the front and rear
axles that react immediately to all driving situa‐
tions.
Programs
The system offers two different programs.
The programs can be selected via the Driving
Experience Switch, refer to page 110.
SPORT
Sporty tuning for greater driving agility.
COMFORT
Comfort-oriented tuning for optimal comfort.
Dynamic Damping Control
The concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs
The system offers three different programs.
The programs can be selected via the Driving
Experience Switch, refer to page 110.
SPORT
Consistently sporty control of the shock absorb‐
ers for greater driving agility.
COMFORT
Balanced tuning between the COMFORT+ and
SPORT programs.
COMFORT+
Comfort-oriented tuning of the shock absorbers
for optimal traveling comfort.
Integral Active Steering
The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.Seite 109Driving stability control systemsControls109
Online Edition for Part no. 01 40 2 607 855 - 09 11 490

At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle as
the front wheels.
In critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.1.With the engine running, turn the steering
wheel all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.2.Have the system checked if the warning
lamp does not go out after moving the steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure that the rear axle steering is deactivated
when using snow chains, refer to page 269.
Programs
The system offers two different programs.
The programs can be selected via the Driving
Experience Switch, refer to page 110.
SPORT
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
COMFORT
Balanced tuning of the Integral Active Steering
for optimal traveling comfort.
Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range.
The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Self-leveling suspension
The concept
The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
Malfunction
A Check Control message is displayed. A mal‐
function has occurred in the self-leveling sus‐
pension. Vehicle handling may be altered and
driving comfort may be noticeably reduced. Visit
your nearest service center.

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Active Cruise Control with
Stop & Go function, ACC
The concept
This system can be used to select a desired
speed that the vehicle will maintain automati‐
cally on clear roads.
To the extent possible, the system automatically
adjusts the speed to a slower vehicle ahead of
you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
If the vehicle ahead of you brakes to a halt, the
system is able to detect this within the given
system limits. If the vehicle ahead of your drives
away again from a halt, your vehicle is able to
accelerate if operated accordingly.
Even if some time passes before the vehicle
drives away again, the BMW can still be accel‐
erated automatically and simply.
As soon as the road is clear, it accelerates to the
desired speed.
The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient.Buttons at a glance1System on/off, interrupt2Resume speed3Store speed4Reduce distance5Store, maintain/change speed6Increase distance

the device should be switched off immedi‐
ately. In this case, please contact the man‐
ufacturer and only use the product after the
problem has been corrected.3.The "legal communication" specified above
refers to communication in accordance with
telecommunication regulations. Low-power
devices should withstand interference from
legal communication and ISM devices.
Collision warning with
braking function
The concept
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings
may vary depending on the current driving sit‐
uation.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control, refer to page 106, is
switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.
