To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC
Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC lights up in the instru‐
ment cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC
Press the button.
DSC OFF and the DSC indicator lamp
go out.
Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The 
indicator lamp lights up: DSC is de‐
activated.
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
When dynamic traction control (DTC) is acti‐
vated, there is maximum traction on loose road
surfaces.The TRACTION* program is acti‐
vated.The driving stability is limited during ac‐
celeration and during cornering.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
lights up.
Deactivating DTC
Press the button again.
TRACTION 
and the DSC indicator lamp
go out.
Indicator/warning lamps
When DTC is activated, TRACTION is displayed
in the tachometer.
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 requiring brake applica‐
tion, the vehicle moves at slightly more than
twice walking speed. Seite 96

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 253.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page  99.
SPORT
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
NORMAL
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.
Dynamic Driving Control*
The concept
Dynamic Driving Control can be used to adjust
the driving dynamics of the vehicle. Several pro‐
grams are available for this purpose; they can be
activated using the two Dynamic Driving Control
buttons. Operating the programs Press the button Program

COMFORT*
For Dynamic Damper Control*, the lower button
is labeled with COMFORT.
Automatic program change
The 
system automatically switches to NORMAL
in the following situations:
▷ Failure of Integral Active Steering*.
▷ Failure of Dynamic Damping Control*.
▷ The vehicle has a flat tire.
DSC OFF
When 
 DSC OFF, refer to page  95, is active, driv‐
ing stability is limited during acceleration and
when driving in bends.
TRACTION
When TRACTION is active, the vehicle has max‐
imum traction on loose road surfaces. DTC Dy‐
namic Traction Control, refer to page  96, is ac‐
tivated. Driving stability is limited during
acceleration and when driving in bends.
SPORT+
Sporty driving with optimized chassis and sus‐
pension during limited driving stabilization.
Dynamic Traction Control is switched on.
The driver handles several of the stabilization
tasks.
Activating SPORT+
Press the button repeatedly until
SPORT+ appears in the tachometer Seite 99

The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The 
support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire., refer to
page  90
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷ 225/55 R 17.
▷ 245/45 R 18.
Follow the chain manufacturer's instructions.
Make 
 sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains. Snow chain detection*
The concept
When using snow chains, you should set
whether you are driving with or without snow
chains via the iDrive.
The 
snow chain detection system supports you
by automatically showing the detected state on
the Control Display.
When snow chains are in use, the rear axle steer‐
ing of the Integral Active Steering* is deacti‐
vated automatically.
At speeds above the maximum allowable speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
Activating the status
1. "Settings"
2. "Tire chains"
3. "Tire chains installed"
Automatic detection
If functioning properly:
▷ Snow chains are mounted. The setting is not
activated     .
After you drive a short distance, a Check
Control message is shown and the state is
activated automatically.
Confirm the automatic activation.
▷ Snow chains are not mounted. The setting
is activated     .
At speeds above 30 mph/50 km/h, a Check
Control message is displayed. Deactivate
the status manually.
If not functioning properly:
▷ Snow chains are mounted. The setting is not
activated     .
A Check Control message is not displayed.
The 
automatic detection system is malfunc‐
tioning. Activate the status manually.
