DTC Dynamic Traction
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.
Deactivating/activating DTC Dynamic
Traction Control
The

system can be deactivated/activated via the
TRACTION and SPORT+ programs of the Dy‐
namic Driving Control, refer to page 103.
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 requiring brake applica‐
tion, the vehicle moves at slightly more than
twice walking speed. You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. twice walking speed and then keeps
its speed constant.
While you are actively braking, the system is on
standby.

The system does not brake the vehicle
during this time.
Increasing or decreasing vehicle speed
You can specify your 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. You can change
the vehicle speed by pressing on the accelerator
lightly. ▷
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.

Driving comfort
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 glance 1

▷ HDC is activated.
Maintaining/storing the current speed Press the button.
When the system is switched on, the current
speed is maintained and stored as the desired
speed. It is displayed in the speedometer and briefly
displayed in the instrument cluster, Displays in

115.
When cruise control is maintained or stored,
DSC

Dynamic Stability Control is switched on, if
necessary.
Change, maintain speed
The rocker switch can be pressed while inter‐
rupted to maintain and store the current speed.
Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; other‐
wise, there is the danger of an accident occur‐
ring.◀ Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed if the road is
clear.
▷
Each time the rocker switch is pressed to the
point of resistance, the desired speed in‐
creases or decreases by approx. 1 mph/
1 km/h.
▷ Each time the rocker switch is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h.
▷ Pressing the rocker switch to the resistance
point and holding it accelerates or deceler‐
ates the vehicle without requiring pressure
on

the accelerator. After the rocker switch is
released, the vehicle maintains its final
speed. Pressing the switch beyond the re‐
sistance point causes the vehicle to accel‐
erate more rapidly. Seite 114
