When Active Lane Change Assist is available, the
± displa y appears along with green arrows in
the driver's display. If the system has been activa-
ted but is not currently available, the ± displayappears along with grey arrows in the driver's dis-
pla
y.
If no vehicle or obstacle is detected in the adja-
cent lane and a lane change is permitted, the lane
change begins aser the driver has indicated
brieOy. The lane change is shown to the driver
with a Oashing green arrow next to the ±
steering wheel symbol. Green arrow Assistance is
displayed in the appropriate adjacent lane in the
1 menu in the driver's display. Themessage, for
Lane change to the left example, also appears.
Active Lane Change Assist can be cancelled in
various situations, including the following: = Change in the surrounding conditions (e.g.
detected obstacle).
= The driver removes their hands from the steer-
ing wheel.
= The driver steers with too much force or in the
opposite direction.
= The driver moves the turn signal indicator in
the opposite direction.
= Active Distance Assist DISTRONIC or Active
Steering Assist is deactivated. =
The v ehicle cannot make the lane change as
planned.
Cancellation of Active Lane Change Assist is dis-
played as follows: = The arrow in the selected direction of travel
turns red.
= A corresponding message will also appear in
the driver's display.
= In certain circumstances a warning tone
sounds. &
WARNING Risk of accident when c
hanging
lane to an occupied adjacent lane
Lane Change Assist cannot always clearly
de
tect if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free. 
Before changing lanes, make sure that
t

he neighbouring lane is free and there is
no danger to other road users. 
Monitor the lane change. 262

WARNING Risk of accident if Lane Chang e
Assist unexpectedly stops functioning
If the system limitations for Lane Change
Assis
t have been reached, there is no guaran-
tee that the system will remain active.
Lane Change Assist cannot then assist you by
applying steering torque. 
Always monitor the lane change and
k

eep your hands on the steering wheel.
Observe the traPc conditions and steer
and/or brake if necessary. System limits
The sy

stem limitations of Active Steering Assist
apply to Active Lane Change Assist
(  page 257).
The system may also be impaired or may not func-
tion in the following situations:
= The sensors are damaged, covered or dirty
(  page 236).
= The exterior lighting shows a defect. =
The sy
stem does not detect a suitable road,
forexample, in tight bends or shortly aser a
slip road.
= The vehicle is on a construction site.
% The Active Lane Change Assist sensors adjust
aut

omatically while a certain distance is being
driven aser the vehicle has been delivered.
Active Lane Change Assist is unavailable or
only partially available during this teach-in
process, and no arrows are displayed next to
the Ø Active Steering Assist symbol.
Observe the notes on driving systems and your
r
esponsibility; you may otherwise fail to recognise
dangers ( page 236).

Function of Active Brake Assist
A

ctive Brake Assist consists of the following func-
tions:
= Distance warning function
= Collision warning
= Autonomous braking function
= Situation-dependent braking assistance
= Vehicles with Driving Assistance Package and
Active Steering Assist: Evasive Steering Assist
Active Brake Assist can help you to minimise the
risk of a collision with vehicles, cyclists or pedes-
trians or to reduce the eMects of such a collision.
If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the / dis-
tance warning lamp lights up. Driving and parking
263

In the Assistance
menu, an insuPcient dis tance
1 to the vehicle in front is displayed in red. If you
further reduce the distance, the vehicle in front is
also highlighted in red. When the system detects a
risk of collision, red radar waves 2 appear in
front of the vehicle.
% Vehicles with PRE-SAFE n
: depending on t
he
country, an additional haptic warning occurs
in the form of slight, repeated tensioning of
the seat belt.
If you do not react to the warning, autonomous
br
aking can be initiated in critical situations.
In particularly critical situations, Active Brake
Assist can also initiate autonomous braking directly. In this case, the warning lamp and warn-
ing t

one occur simultaneously with the braking
application.
If you apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance
occurs. The brake pressure increases up to maxi-
mum full-stop braking if necessary. If autonomous braking or situation-dependent
br

aking assistance has occurred, pop up 1
appears in the driver's display and then automati-
cally goes out aser a short time.
If the autonomous braking function or the situa-
tion-dependent braking assistance is triggered, additional preventive measures for occupant pro-
t
ection (PRE-SAFE n
) may also be initiated. &
WARNING Risk of an accident caused b
y
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and com
plex traPc situations.
In such cases, Active Brake Assist might:
= Give a warning or brake without reason
= Not give a warning or not brake
Active Brake Assist is only an aid. The driver is
responsible for maintaining a suPciently safe
distance to the vehicle in front, vehicle speed
and for braking in good time. 
Always pay careful attention to the tr
aPc
situation; do not rely on Active Brake
Assist alone. 
Be prepared to brake or swerve if neces-
sar

y. If Active Brake Assist is deactivated or the func-
tions ar
e restricted, e.g. due to activation of 264

Situation-dependent braking assistance
If the vehicle is travelling at speeds above approx-
imately 7 km/h, situation-dependent braking
assistance may intervene in the following situa-
tions.
Vehicles without Driving Assistance Package:

Assis t
You can cancel a brake application of Active
Brake Assist at any time by: = Fully depressing the accelerator pedal or with
kickdown.
= Releasing the brake pedal.
Active Brake Assist may cancel the brake applica-
tion when one of the following conditions is fulNl-
led:
= You manoeuvre to avoid the obstacle.
= There is no longer a risk of collision.
= An obstacle is no longer detected in front of
your vehicle.
Reaction to oncoming road users (only vehicles
with Driving Assistance Package)
Active Brake Assist can also react to detected
oncoming road users: = Reaction up to speeds of approximately
100 km/h

clearly.
Moreover, the steering support provided by
Evasive Steering Assist is not suPcient to
avoid a collision. 
Always pay careful attention to the tr
aPc
situation; do not rely on Evasive Steering
Assist alone. 
Be prepared to brake or swerve if neces-
sar

y. 
End the support by actively steering in
non-cr
itical situations. 
Drive at an appropriate speed if there
ar

e pedestrians close to the path of your
vehicle. Evasive Steering Assist has the following charac-
t

eristics:
= Detection of pedestrians, cyclists and vehi-
cles.
= Assistance through power-assisted steering if
it detects a swerving manoeuvre.
= Activation by an abrupt steering movement
during a swerving manoeuvre.
= Assistance during swerving and straightening
of the vehicle.
= Reaction from a speed of approximately
20 km/h up to a speed of approximately
110 km/h.
The steering support of Evasive Steering Assist
can be cancelled at any time by counter steering.

%
Speed Limit Assist uses OpenStreetMap data,
whic
h is made available under the conditions
of the Open Database License (OBbL). For
more information, see: https://
www.osmfoundation.org/wiki/licence.
Speed Limit Assist detects speed limits with multi-
function camer
a and displays them in the driver's
display and optionally in the head-up display. The
camera also detects speed limits with a restric-
tion indicated by an additional sign (e.g. when
wet).
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 236).
Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by how much the maximum permissible speed can
be e

xceeded before a warning is issued. You can
specify whether the warning is to be just a visual
warning or an acoustic one as well (  page 269).

ways, can also be detected. 268
Driving and parking

The system can show up to two
tr aPc signs in the
driver's display simultaneously. The system always
prioritises displaying speed limits. Up to one traf-
fic sign with a maximum permissible speed can be
shown in the head-up display. If two speed signs
are shown in the driver's display, forexample when
speed limits are detected, the value of les-hand
speed limit 1 is transmitted to the limiter, cruise
control or Active Distance Assist DISTRONIC for
adoption and is shown in the head-up display.
If Speed Limit Assist cannot determine the cur-
rent maximum permissible speed (e.g. due to
missing signs), the following display appears in
the driver's display: This is displayed continuously if the vehicle is in a
countr

y where Speed Limit Assist is not suppor-
ted. Speed Limit Assist is not available in all coun-
tries. System limits
The sy

stem may be impaired or may not function
particularly in the following situations:
= If visibility is poor, e.g. due to insuPcient illu-
mination of the road, highly variable shade
conditions, rain, snow, fog, swirling dust or
heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If traPc signs are diPcult to detect, e.g. due
to dirt, snow, ice, insuPcient lighting or driving
too close to the vehicle in front, or because
they are covered, faded, damaged, badly posi-
tioned or twisted.
= Digital LED traPc signs may not be detected
correctly or at all due to technical factors,
suchas transmission frequency.
= If signs or the road layout is ambiguous, e.g.
traPc signs in roadworks, at exits and ramps,
in neighbouring lanes or parallel roads. =
If signs do no t conform to the standard.
= If signs or road layouts are speciNc to the
country, forexample, at or beyond construc-
tion sites.
= Aser sharp turns and tight bends, when traPc
signs are outside the camera's Neld of vision.
= If you overtake vehicles with traPc signs
which are aPxed or attached to them.
= If you are using transport equipment secured
with a trailer coupling, suchas a bicycle rack,
the system may react to restrictions for car/
trailer combinations.
