Dynamic Traction Control and DSC are deacti‐
vated together.
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.
Activating DSC Press the button.
DSC OFF and the indicator lamp in the
instrument cluster go out.

trols the drive forces and brake forces.

Dynamic Traction Control
DTC
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate 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 vehicle free or starting off
in deep snow, sand, or on loose ground▷When driving with snow chains.
Deactivating/activating DTC Dynamic
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.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for
DSC OFF lights up.

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 inter‐
vention.
xDrivexDrive 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 driv‐
ing situation and prevailing road conditions.
Hill Descent Control HDC
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without requiring brake ap‐
plication, 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 at below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approx. twice walking speed and keeps it
constant.
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.1Increasing speed2Decreasing speedSeite 99Driving stability control systemsControls99

button lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC Press the button again; the LED goes

above approx. 37 mph/60 km/h.

HDC can be used in every driving position.

Malfunction
If the HDC display goes out during HDC opera‐
tion or is not displayed: HDC is not available
due to high brake temperatures or DSC has
failed.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Servotronic The conceptThe Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving.
Power steering provides strong support at low
speeds, which means that less effort is needed
to turn the wheels. Power steering support
lessens as your speed increases.
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
possible.

Driving comfortVehicle equipment
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
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Cruise control The concept
The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
The speed specified using the lever on the
steering column is maintained.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Maintaining current speed
Push, arrow 1, or pull, arrow 2, the lever to the
resistance point.
The car's current speed is stored and main‐ tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.Seite 101Driving comfortControls101

MalfunctionThe warning lamp lights up. The sys‐
tem is malfunctioning or has failed.
A message appears on the Control
Display. More information, refer to page 80.
Park Distance Control PDC
The concept In addition to the PDC Park Distance Control,
the backup camera, refer to page 105, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your
vehicle is announced by:▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle may prevent you from hearing the PDC's
signal tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
High, protruding objects such as ledges may
not be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Seite 103Driving comfortControls103
