the Mobility System. If the tire inflation
pressure in all tires is correct, the Flat Tire
Monitor may not have been initialized. In
this case, initialize the system.3.Repair flat tire with the Mobility System or
replace the damaged wheel.
System limits
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
Sudden serious tire damage caused by exter‐
nal circumstances cannot be recognized in ad‐
vance.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
Intelligent Safety
The concept
Intelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.
▷Front-end collision warning with City Brak‐
ing function, refer to page  117.▷Pedestrian warning, refer to page  119.▷Lane departure warning, refer to
page  125.▷Active Blind Spot Detection, refer to
page  127.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.◀

Active ProtectionGeneral 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.▷When the road surface is poor.▷In the event of strong side winds.
PreCrash
The concept With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In these situations, preventive measures are au‐
tomatically taken to minimize the risk of an ac‐
cident as much as possible.
Critical driving situations may include:
▷Emergency stop.▷Severe understeering.▷Severe oversteering.Seite 130ControlsSafety130

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.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.
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
curve to the wheel on the outside of the curve
or vice-versa.
To increase the maneuverability, the rear
wheel on the outside of the curve is acceler‐
ated when the driving style is correspondingly
sporty.
The steering responds directly; simultane‐
ously, the understeering tendency of the four-
wheel drive is reduced.
With the oversteering tendency, the system
exerts a stabilizing effect by accelerating the
rear wheel on the inside of the curve.
The system noticeably improves the traction
and simultaneously increases the driving

Pathway lines depend on the current steering
angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can only be superimposed
on the rearview camera image together with
pathway lines.
Turning circle lines show the course of the
smallest possible turning radius on a level
road.
Only one turning radius line is displayed after
the steering wheel is turned past a certain an‐
gle.

▷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.

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.
