Display in the instrument clusterThe selected speed is displayed
in the speedometer.▷Green: the system is actively
braking the vehicle.▷Orange: the system is on
standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Active Steering
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At lower speeds, for example during turning or
maneuvering, the steering angle is increased,
that is to say the steering becomes more di‐
rect.
At higher speeds, the steering angle is increas‐
ingly reduced.
This enables even more precise handling at
high speeds and more responsive steering
with reduced steering angle at low speeds.
Active roll stabilization The concept
The system 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 sys‐
tem utilizes active stabilizer bars on the front
and rear axles that react immediately to all driv‐
ing situations.
Programs
The system offers two different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
SPORT Sporty tuning for greater driving agility.
COMFORT
Comfort-oriented tuning for optimal comfort.
Vertical Dynamic 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 fitting road surface and driving style.
Programs The system offers several different programs.
Select the programs via the Driving Dynamics
Control, refer to page 137.
SPORT/SPORT+
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning.
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.Seite 136ControlsDriving stability control systems136

▷Adjust the speed to the road surface con‐
ditions. The steeper and more uneven the
road surface, the slower the speed should
be.▷When driving on steep uphill or downhill
grades: add engine oil and coolant up to
near the MAX mark. Uphill and downhill
grades can be traveled up to no more than
50 %.▷On steep downhill grades, use Hill Descent
Control HDC, refer to page 135.
Starting out is possible on uphill grades up
to 32 %. The permissible side tilt is 50 %.▷Avoid that the chassis bottom coming in
contact with the ground.
The ground clearance is no more than 7.8
inches/20 cm and can vary according to
the vehicle's load.▷When wheels continue to spin, depress the
accelerator so that driving stability control
systems can distribute the driving force to
the wheels. Activate DTC Dynamic Trac‐
tion Control if available.
After a trip on poor roads
After a trip on poor roads, check wheels and
tires for damage to maintain driving safety.
Clear heavy soiling from the body.
