The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differ‐
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety The concept
Intelligent Safety enables central operation of
the driver assistance system. Depending onhow the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.▷Front-end collision warning, refer to
page 119.▷Pedestrian warning, refer to page 125.▷Lane departure warning, refer to
page 131.▷Active Blind Spot Detection, refer to
page 133.
Information
WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem limits, warnings or reactions of the system
may not be output or they may be output too
late or incorrectly. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g. approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀

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 142.
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 142.
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 141Driving stability control systemsControls141

The minimum speed that can be set is
20 mph/30 km/h. The maximum speed that
can be set depends on the vehicle.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system also does not decelerate in the fol‐
lowing situations:
▷For pedestrians or similar slow-moving
road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed.
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀

Warning of crossing traffic
The concept When an object approaching from the side is
detected by the front or rear camera, this is de‐
picted by a symbol in the Side View display.
Requirements
▷Side View switched on.▷Your vehicle moves no faster than walking
speed.▷To detect approaching objects, sufficient
brightness, e.g., daylight is necessary.
Display
The yellow symbol is displayed if anapproaching vehicle is detected by the
camera.
A gray symbol is displayed if crossing
traffic cannot be detected.
System limits
In the following situations, the warning about
crossing traffic may be limited:
▷In poor lighting or visibility conditions.▷If the camera is soiled or covered.
System limits
The objects displayed on the Control Display
under certain circumstances are closer than
they appear. Therefore, do not estimate the
distance from the objects on the display.
The viewing angle is approx. 180°.
