help in preventing signs of fatigue.
General information After each start of the vitalization program,
there is a calibration run. Here the intensity of
the exercises is set individually.
Videos on the respective screens in the rear
show, which motions should be executed. A
display informs about the still-remaining dura‐
tion of each exercise. There is direct feedback
to the exercise executed by a display of stars
and a color bar display:
▷Green: exercise was correctly executed.▷Gray: the pressure was too weak.▷Red: the pressure was too weak.
The goal of the exercises is to keep the bar
display in the green area as long as possible.
Every exercise is evaluated by awarding stars.

Head-up Display
Overview
The concept
This system projects important information
into the driver's field of vision, e. g., the speed.
The driver can get information without averting
his or her eyes from the road.
Information Follow the instructions for cleaning the Head-
up Display, refer to page 294.
Display visibility The visibility of the displays in the Head-up
Display is influenced by the following factors:
▷Certain sitting positions.▷Objects on the cover of the Head-up Dis‐
play.▷Sunglasses with certain polarization filters.▷Wet roads.▷Unfavorable light conditions.Seite 126ControlsDisplays126

SymbolMeasureSymbol lights up red: prewarning.
Brake and increase distance.Symbol flashes red and an acoustic
signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by an automatic braking intervention
in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Brake intervention, City braking
function
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can additionally assist possibly
with automatic braking intervention if there is
risk of a collision.
At low speeds the vehicle can be decelerated
to a complete stop.
The braking intervention takes place up to ap‐
prox. 50 mph/80 km/h.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
With radar sensor and Active CruiseControl: braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can assist with automatic braking
intervention if there is risk of a collision.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
Above approx. 130 mph/210 km/h the braking
intervention occurs as a brief braking pressure.
No automatic delay occurs.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Detection range
The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:Seite 143SafetyControls143
Online Edition for Part no. 0140 2 964 330 - VI/15
▷Automatic closing of the glass sunroof, in‐
cluding sliding visor.▷For vehicles equipped with Comfort seats
in the front: automatic positioning of the
backrest for the front passenger seat.▷For vehicles equipped with Comfort seats
in the rear: automatic positioning of the
backrests for the rear passenger seats.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
Post Crash — iBrake The conceptIn certain accident situations, e.g. collision, the
system can bring the vehicle to a halt automat‐
ically without driver intervention. This can re‐
duce the risk of a further collision and the con‐
sequences thereof.
At standstill After coming to a halt, the brake is released
automatically.
Harder vehicle braking
It can be necessary to bring the vehicle in cer‐
tain situations to a halt quicker.
Here, a higher braking pressure must be gen‐
erated for a short period when pressing the brake pedal than during automatic braking.
This interrupts automatic braking.
Interrupting automatic braking It can be necessary to interrupt automatic
braking in certain situations,e.g. for an evasive
maneuver.
Interrupt automatic braking:
▷By pressing the brake pedal.▷By pressing the accelerator pedal.
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 switched on each time drive
readiness is switched on.
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.

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.
The possible holding duration amounts to
2 minutes.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Information
Adapt your driving style to the situation, for an
appropriate driving style is always the respon‐
sibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.
