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 116.▷Pedestrian warning, refer to page 122.▷Lane departure warning, refer to
page 128.▷Active Blind Spot Detection, refer to
page 130.
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.◀

Brake force display
The concept▷During normal brake application, the bot‐
tom brake lights light up.▷During heavy brake application, the top
brake lights light up in addition.
Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷Attentiveness assistant.▷PreCrash.▷PostCrash
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this situation, it is recommended that the driver
takes a break.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess
one's physical state. An increasing lack of
alertness or fatigue may not be detected or not
be detected in time. There is risk of an acci‐
dent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic con‐
ditions.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:▷Personal driving style, e.g., steering behav‐
ior.▷Driving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:
▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering fast.▷In active driving situations, such as when
changing lanes frequently.Seite 132ControlsSafety132

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
Automatic Differential Brake The system controls the driving force by auto‐
matic braking intervention on individual
wheels. The function corresponds to a differ‐
ential lock: the system detects if a wheel be‐
gins to spin, because of loose road surface,
e.g., and automatically brakes it.
The driving force is diverted to the wheel with
better traction.
As a result, the engine force is transferred
more efficiently to the wheels during accelera‐
tions.
Dynamic Performance
Control DPC
The Dynamic Performance Control increases
both the agility of the vehicle as well as the
lane stability.
The system seamlessly handles the distribu‐
tion of the drive torque between the two rear
wheels.
Depending on the situation, the drive torque is
shifted from the wheel on the inside of the

pathway lines
▷The static, red turning radius line shows
the space needed to the side of the vehicle
when the steering wheel is turned all the
way.▷The variable, green pathway line assists
you in assessing the amount of space ac‐
tually needed to the side of the vehicle.
The lane line depends on the engaged
gear and the current steering angle. The
track line is continuously adjusted for the
steering wheel movement.
"Parking aid lines"
Turning circle and pathway lines are displayed.
System limits
A Check Control message is displayed when a
camera is not working.
Side View The concept
Side View provides an early look at cross traffic
at blind driveways and intersections. Road
users concealed by obstacles to the left and
right of the vehicle can only be detected rela‐
tively late from the driver's seat. To improve
the viewing, each camera, front and rear on the
vehicle, detects the traffic area on the side.
Which camera is active is shown on the top
edge of the screen.
Information The images of the cameras are displayed, de‐
pending on the gear selected, on the Control
Display.
WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic and vehicle surroundings
closely and actively interfere in the respective
situations.◀
