Always switch off the speed limiter after use
to avoid unintentional cruise control.
• The speed limiter does not relieve the
driver of their responsibility for the speed of
the vehicle. Do not drive at full throttle if it is
not required.
• Use of the speed limiter in adverse weath·
er conditions is dangerous and can cause se­
rious injury, e.g. through aquaplaning, snow,
ice, or leaves. Only use the speed limiter
when the road and weather conditions allow
it to be used safely.
• The speed limiter cannot limit the vehicle
speed when travelling downhill. The vehicle
speed can increase under its own weight.
Shift down a gear or brake the vehicle using
the foot brake.

The following conditions can prevent the
adaptive cruise control from reacting:
• If the the acce le rator is depressed.
• If no g ear is selected .
• If the ESC is taking corre ctive action .
• If the driv er h as no t f astened seat belt.
• If there is a fau lt in seve ral brake lights on the

connection

• If the vehicle is reve rsing .
• If the vehicle is travelling faster than approxi ­
mately 160 km/h (100 mph).
A WARNING
If you close the gap to a vehicle in front and
the difference in speed between the two vehi­
cles is so great that the braking action of the
ACC is insufficient, you are in danger of col­
liding with the vehicle in front. You should re­
duce the vehicle speed immediately with the
foot brake.
• The ACC may not be able to recognise all
driving situations correctly.
• Leaving your foot on the accelerator will
mean that the ACC will not brake automatical­
ly. This is because manual acceleration over­
rides the system.
• You should always be prepared to brake
the vehicle yourself.
• Observe country-specific regulations re­
garding the minimum distance.
rn
The set speed will be deleted if the ig nition or
the ACC is switched off.

The ACC is automatically deactivated when
the tract ion control system (T CS ) is deactiva-

The adapttve cruise contro l (ACC) should be

• When driving through a tunnel as this situation

• On roads with more than one lane, if other vehi­

The area monitoring system (Front Assist) helps to
avoid rear-end collisions.
lt uses a radar sensor to monitor traffic situations
up to a distance of approximately 120 metres in
front of the vehicle within a speed range of approx­
i
mately 5 km/h (3 mph) to 210 km/h (130 mph) .
The area monitoring system (Front Assist) can
warn the driver about imminent collisions, pre­
pare the vehicle for emergency braking in case
of danger, assist with braking, and initiate auto­
matic braking.

Distance warning
If the system detects danger from driving too close
to.the vehicle in front , the system can warn the
~nver by showing a corresponding message in the
~nstrument cluster display ~page 236. The warn­
Ing Period varies according to the traffic situation
a
nd the driver's response . Front Assist is not a
sub t · · s ltue for the full concentration of the dnver .
Advance warning
h lfth e system detects a potential collision with a ve­ICI · e .e .1n front, the system can warn the driver by 1111tt1ng an acoustic warning and showing a corre-spond· · PI lng message in the instrument clus~er diS-
ay ~Page 236 . The warning period vanes ac- carding
to the
traffic situation and the driver's re­
sponse . Front Assist is not a substitue for the
full
concentration of the driver .
At the
same time it prepares the vehicle for possi­
ble emergency braking ~ ~.
Urgent warning
If the driver fails to respond to the advance warn­
ing, the system can initiate a quick jolt of the brake
in order to draw the driver's attention to the
in­
creasing danger of a collision.
Automatic braking
If the driver also fails to react to the urgent warn­
ing, the system can slow the vehicle down auto­
matically by gradually increasing the braking force.
The system can help to reduce the consequences
of an accident by reducing the speed at which a
potential collision might take place .
Brake assistance
If Front Assist detects that the driver is not braking
sufficiently when there is a risk
of collision , the sys­
tem can increase the braking force and thereby
help to prevent a collision . Brake assistance works
only
for as long as the brake pedal is pressed
hard.
The intelligent technology used in Front As­
sist cannot overcome the laws of physics.
The driver is always responsible for braking
in time. If Front Assist issues a warning, im­
mediately apply the foot brake to slow the ve­
hicle down or avoid the obstacle, depending
on the traffic situation.
• Adapt your speed and distance from the
vehicles ahead to suit visibility, weather, road
and traffic conditions.
• Front Assist cannot prevent accidents and
serious injuries on its own.
• Front Assist can issue unnecessary warn­
ings and carry out unwanted braking inter­
ventions in certain complex driving situa­
tions, e.g . at traffic islands.
