Concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immij
nent collision and actuates brakes independj
ently, if needed.
The automatic braking intervention is done with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The approach control warning is available even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the approach control warning and braking are delayed in order to avoid false sysjtem reactions.
General
information
The system warns at two levels of an imminent danger of collision at speeds from approx.3 mph/5 km/h. Time of warnings may vary withthe current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.Detection
range
Objects are responded to if they are detected
by the system.
Safety
information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj tem may not be output or they may be output
too late or incorrectly. There is a risk of an acj cident. Adjust the driving style to the traffic
conditions. Watch traffic closely and activelyintervene in the respective situations.'

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 maneuj
ver.
Prewarning
This warning is issued, e.g., when there is the impending danger of a collision or the distanceto the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute
warning
with
braking
function
Acute warning is displayed in case of the immij nent danger of a collision when the vehicle apj
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking interj
vention in a possible risk of collision.

Acute warnings can also be triggered without
previous forewarning.
Braking
intervention
The warning prompts the driver himself/herself to react. During a warning, the maximum brakj
ing force is used. Prerequisite for the brake booster is sufficiently quick and hard steppingon the brake pedal. The system can assist withsome braking intervention if there is a risk of acollision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking interj
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if vej
hicle stability has not been restricted, e.g., by
deactivating the DSC Dynamic Stability Conj
trol.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by acj
tively moving the steering wheel.
Object detection can be restricted. Observe
the limitations of the detection range and funcj tional restrictions.
System
limits
Safety
information WARNING
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe the information regarding the system limits
and actively intervene, if needed.'

The camera in the area of the rearview mirror
controls the system.
General
information
With sufficient brightness, the system warns about possible collision danger with pedesjtrians starting at approx. 6 mph/10 km/h to apj
prox. 35 mph/60 km/h and assists with braking before a collision.
Under those circumstances it reacts to people who are within the detection range of the sysj
tem.
Detection
range
The detection area in front of the vehicle is divjided into two areas:
'yCentral area, arrow 1, directly in front of thevehicle.'yExpanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are loj
cated within the central area. A warning is isj
sued about pedestrians who are located within the extended area only if they are moving inthe direction of the central area.
Safety
information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj
tem may not be output or they may be output
too late or incorrectly. There is a risk of an acj

conditions. Watch traffic closely and actively intervene in the respective situations.'

Lane
departure
warning
Concept
Starting at a specific speed, this system alerts you when the vehicle on streets with lane markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instruj
ment cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sitj uation.
The system does not provide a warning if the turn signal is set before leaving the lane.
Safety
information WARNING
The system does not release the driver
from the personal responsibility to correctly assess route and traffic situation. There is arisk of an accident. Adjust the driving style to
the traffic conditions. Watch traffic closely and actively intervene in the respective situations.In the event of a warning, do not unnecessarilyjerk the steering wheel.'

Issued
warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vij
brating.
If the turn signal is set before changing the
lane, a warning is not issued.
End
of
warning
The warning is canceled in the following situaj tions:'yAutomatically after approx. 3 seconds.'yWhen returning to your own lane.'yWhen braking hard.'yWhen using the turn signal.

Brake
force
display
Concept
Additional brake lamps indicate emergency
braking to the traffic behind. This can reduce
the risk of a rear-end collision.
General
information'yDuring normal brake application, the outer brake lights light up.'yDuring heavy brake application, the innerbrake lights additionally light up.
Attentiveness
assistant
Concept
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, e.g., on highways. In this situation, it is
recommended that the driver takes a break.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess one's physical state. An increasing lack ofalertness or fatigue may not be detected or notbe detected in time. There is a risk of an accijdent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic conj
ditions.'

This procedure takes the following criteria into
account:'yPersonal driving style, e.g., steering behavj
ior.'yDriving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommenj dation to take a break.
Break
recommendation
If the driver becomes 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 approxij
mately 45 minutes.
System
limits
The function may be limited in the following
situations, e.g., and will either output an incorj
rect warning or no warning at all:
'yWhen the clock is set incorrectly.'yWhen the vehicle speed is mainly below about 43 mph/70 km/h.'yWith a sporty driving style, such as duringrapid acceleration or when cornering fast.'yIn active driving situations, such as when
changing lanes frequently.'yWhen the road surface is poor.'yIn the event of strong side winds.
The system is reset approx. 45 minutes after
parking the vehicle, e.g., in the case of a break during longer trips on highways.
