Vehicle equipment
Dynamic Stability Control
DSC
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes to the individual wheels.
Antilock Brake System ABS
Adjust your driving style to the situation
ABS prevents locking of the wheels during brak‐
ing.
An appropriate driving style is always the
responsibility of the driver.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin with
a risky driving style, as otherwise there is a risk
of an accident.◀
ABS is operational every time you start the en‐
gine.
Deactivating DSC: DSC OFF
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Brake assistant
Deactivating DSC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the

Dynamic Traction Control and DSC are deacti‐
vated together.
Dynamic Traction Control
DTC
The concept
In the interest of better forward momentum,
brake intervention is performed in the manner of
a differential lock when the drive wheels spin
quickly even if DSC is deactivated.
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.
Activating DSC
It is therefore necessary to drive with appropri‐
ate caution.
Press the button.
DSC OFF and the indicator lamp in the
instrument cluster go out.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:
▷
When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces
For better control
The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.

▷
When rocking a vehicle free or starting off in
deep snow, sand, or on loose ground
The indicator lamp lights up: DSC and
DTC has failed.
When driving with snow chains.

Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.

DSC OFF appears in the instrument
cluster.

DSC and DTC deactivated.
Press the button.
TRACTION is displayed in the instru‐

DSC OFF lights up.

Hill Descent Control HDC
Press the button again.
TRACTION and the indicator lamp in
the instrument cluster go out.
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.
For better control
The indicator lamp flashes: DTC con‐
trols the drive forces and brake forces.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
driving downhill at below approx.
The indicator lamp lights up: DSC and
DTC has failed.
22 mph/35 km/h, the vehicle reduces its speed
to approx. twice walking speed and keeps it con‐
stant.
DTC activated:
The indicator lamp lights up and TRAC‐
TION appears in the instrument cluster.
While you are actively braking, the system is on
standby. The system does not brake the vehicle
during this time.
Increasing or reducing speed
The speed can be changed in the range from
roughly twice walking speed to approx.
15 mph/25 km/h by pressing the accelerator or
brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.
DTC is activated.
Performance Control
Performance Control enhances the agility of
your vehicle. To enhance performance during
sporty driving, the rear wheel on the inside of the
curve is braked while the resulting braking effect
is largely compensated by engine intervention.

xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. 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 sit‐
uation and prevailing road conditions.

Drive-off assistant
This system supports driving away on gradients.
The handbrake is not required.
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive away with‐
out delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay

The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again; the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.
Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving.
Using HDC
HDC can be used in every driving position.
Power steering provides strong support at low
speeds, which means that less effort is needed
to turn the wheels. Power steering support less‐
ens as your speed increases.
Displays in the instrument cluster
Malfunction
The warning lamp lights up.A mes‐
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Have the system checked as soon as pos‐
sible.
