Conditions for starting the adaptive cruise
control
• The selector lever must be in position D or S or
be in the Tiptron ic gate. A forward gear, but not 1st
gear , must be selected
in the manu al gearbox .
• In vehicles with a manual gearbox , the actual
speed should be minimum 30 km /h (18 mph) if no
speed is stored .
Controlling speed
When switched on, the speed can be stored and
set. The stored speed can vary from the speed
ac­
tually
being driven if the distance is b ein g act ively
controlled.
Action
The system is switched on. No speed has yet
been stored and the speed is not yet being con-
trolled.
This sw itches between the CCS and the speed
limiter ~page 222 .

The adapttve cruise contro l (ACC) should be
s it c hed off in the following situations due t o sys­
tem limitations -~:
• When turning off roads. driving around round­
abouts, narrow curves. joining motorways, exiting
from motorways or driving through road works, to
prevent th e vehicle from unnecessarily accelerat­
ing to the set speed in these situations
• When driving through a tunnel as this situation
could impair the system function.
• On roads with more than one lane, if other vehi­
cles are driving more s lowly in the fast la ne . The
slower vehicles in the other lane would be o ve rtak­
en from the right side in this case.
• In heavy rain, snow or spray as vehicles tra ve l­
ling
ahead cannot be monitored sufficiently or
maybe cannot be monitored a t all.
Special driving situations
A WARNING
Failure to switch off the ACC in the above ­
mentioned situations can cause acciden ts
and result in serious injuries.
• Switch off the ACC in critical driving situa.
tions.

The adaptive cruise control (ACC) has physical
and system-rel ated limits . As such, certain ACC
system reactions may occur, from the driver's per-

spective , unexpectedly or with some delay. You
should therefore always be prepared to take full
control of the vehicle if necessary .

Stationary phase (only vehicles with
autornatic gearbox)
If the adap tive cruise control has decele ra t d the
vehicle to a standstill, the adapt.ive cruise contr o l
will not be switched off automatically wh en the
brake pedal is depressed .
The electronic parking brake will be activated auto4
matically and the adap tive cruise control will be
switched off if one of the following situations occurs
while the vehicle is stationary:
• The safety be lt is unfastened .
• The driver's door is opened.
• The ignition is switched off.
• The stationary phase lasts longer than approxi4
mately 3 minutes .
Driving off after a stationary phase (only
vehicles with automatic gearbox)
After a stationary phase, the adaptive cruise con­
trol can start the vehicle moving automatically as
soon as the vehicle in front begins to move again.
Overtaking
If the turn signal is activated when starting an over­
taking manoeuvre , the adaptive cruise control ac­
celerates the vehicle automatically and thus re­
duces the distance to the vehicle in front.
If you move your vehicle into the overtaking lane
and there is no vehicle ahead of you , the ACC will
automatically increase the speed to your set level
and maintain it.
Acceleration can be stopped at any point
by de­
Pressing the brake pedal or pressing the @ button
on the multifunction steering wheel ~page 229.
When driving through bends
While dr iving through bends, the radar sensor may
sometimes lose the ve hicle travelling ahead or
rnay r eac t to a ve hicle in the next lane
; Fig. 169 A. In such situations, the vehicle might
.
ecel e rate unnec essarily or not react to the veh icle
In front. In this case the driver must override the
Abcc by depressing the accelerator, or interrupt the rak· lng procedure by depressing the brake peda l

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.

information and warnings:

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.

A WARNING
The intelligent technology of the city emer­
gency brake function cannot change the laws
of physics. The driver is always responsible
for braking in time.
• Adapt your speed and distance from the
Vehicles ahead to suit visibility, weather, road

A WARNING (Continued)
• The city emergency brake function can
carry out unwanted brake interventions in
certain complex driving situations, e.g. at
traffic islands, building sites and metal
tracks.
• Front Assist can issue unnecessary warn­
ings and carry out unwanted braking inter­
ventions when its function is impaired, e .g . if
the position of the radar sensor has been
changed.
• While the vehicle is in motion, Front As­
sist does not react to persons, animals and
vehicles crossing or approaching in the same
lane.
m The brake pedal travel decreases when the
