Function of Active Emergency Stop Assist
Active Emergency Stop Assist monitors the steer-
ing wheel and the accelerator and brake pedals. If
the system detects a lack of driver activity and the
vehicle threatens to leave the lane, a warning can
be issued and an emergency stop initiated.
Vehicles without Driving Assistance Package: The
system is available from a speed of approx. 37 mph (60 km/h).
Vehicles with Driving Assistance package: If
Active Steering Assist is switched oM, the system
is available from a speed of approx. 37 mph
(60 km/h).
If the system detects that the vehicle is threaten-
ing to leave the lane, a warning can be issued and
an emergency stop initiated.
= The driver does not touch the steering wheel
for a longer period of time or no steering
movement can be measured for a longer
period of time (depending on the vehicle
equipment).
= Neither the accelerator nor the brake pedal is
depressed.\bVehicles with Driving Assistance package: if
Active Steering Assist is switched on and
active, only the steering wheel is monitored by
the system. If the driver does not touch the
steering wheel for a longer period of time, a
warning may be given despite pedal actuation. Also observe the instructions on the contactdetection of Active Steering Assist(  page 247).
Active Emergency Stop Assist issues the following
warnings in order:
= Display message 1 appears in the driver\bs
display.
= In addition to display 1 a warning tone
sounds.
= The message Initiating Emergency Stop will
appear in the driver\bs display, a continuous warning tone will sound, the vehicle will no
longer accelerate and, if necessary, slight belt tensioning will be produced.
= The vehicle speed is reduced in increments
until it is at a standstill. Sharp brake impulses
are also produced.
Driving and parking249

\bVehicles with Driving Assistance Package: If
Active Distance Assist DISTRONIC is active
and the driver unfastens the seat belt and driver\bs door, an emergency stop can be initi-
ated immediately.
Vehicles with Driving Assistance Package:
Depending on the country, a lane change to the
adjacent lane is carried out, if possible. It is possi-
ble only to change across one lane and only into
the outer lane, and not onto the hard shoulder.
When automatic braking is initiated, Active Dis-tance Assist DISTRONIC is deactivated. Depend-ing on the country, the hazard warning light sys- tem is switched on.
When the vehicle is stationary, the following actions are carried out:
= The vehicle is secured with the electric park-
ing brake.
= The vehicle is unlocked.
= If possible, an emergency call is placed to the
Mercedes-Benz emergency call center.
Before automatic braking is initiated, you can can-
cel Active Emergency Stop Assist by steering.
You can cancel the intervention by Active Emer- gency Stop Assist aser automatic braking is initi-
ated by one of the following actions:
= Accelerating or braking: the emergency stop is
canceled, but the warning message, warning
tone and power steering remain active
= Steering: power-assisted steering is canceled,
the warning message and warning tone remain
active and the vehicle continues to be braked\bActive Emergency Stop Assist can initiate an emergency stop a maximum of three times
within a driving cycle. Aser that, Active Steer-
ing Assist and Active Emergency Stop Assist
are disabled until the vehicle has been restar-
ted.
System limits
For the detection of vehicles and other obstacles,
observe the system limits of the following func-
tions:

tus display) (  page 266).
Active Lane Change Assist

qFunction of Active Lane Change Assist
Active Lane Change Assist supports the driver when changing lanes and is activated by indicat-
ing brieOy.
For this, the following conditions must be fulNlled:
= You are on a highway or high-speed major
road.
= The vehicle speed is between approximately
40 mph (65 km/h) and 110 mph (180 km/h).
= The neighboring lane is separated by a broken
lane marking.
250Driving and parking

=No vehicle or obstacle is detected in the adja-
cent lane.
= Active Lane Change Assist is selected in the
multimedia system.
= Active Distance Assist DISTRONIC and Active
Steering Assist are switched on and active.Display in the driver\bs display in the menu $ssLs
tDnFH1Green arrow: lane change initiated2Red arrow: lane change canceled
When Active Lane Change Assist is available, the
± display appears along with green arrows in
the driver\bs display. If the system has been activa-
ted but is not currently available, the ± display
appears along with gray arrows in the driver\bs dis-
play.
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\bs display. Themessage, for
Lane Change to the Left example, also appears.
If a lane change is not possible directly aser the
driver has activated the turn signal indicator because an obstacle has been detected, forexam-
ple, the arrow will also Oash in green next to the
± steering wheel symbol and the neighboring
lane will continue to be monitored. When the lane
becomes free, a lane change will be carried out and a message e.g. Lane Change to the Left
appears in the driver\bs display. If the green arrows
stop Oashing, the lane change must be activated
again.Driving and parking251

Active Lane Change Assist can be canceled in var-
ious situations, including the following:
= Change in the surrounding conditions (e.g.
detected obstacle).
= 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 vehicle 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\bs display.
= In certain circumstances a warning tone
sounds.&WARNING Risk of accident when changing
lane to an occupied adjacent lane
Lane Change Assist cannot always clearly detect if the adjacent lane is free.
The lane change might be initiated althoughthe adjacent lane is not free.
Before changing lanes, make sure that
the neighboring lane is free and there is
no danger to other road users.Monitor the lane change.&WARNING Risk of accident if Lane Change
Assist unexpectedly stops functioning
If the system limitations for Lane Change
Assist 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
keep your hands on the steering wheel. Observe the traPc conditions and steer
and/or brake if necessary.System limits
The system limitations of Active Steering Assist
apply to Active Lane Change Assist (  page 247).
The system may also be impaired or may not func-
tion in the following situations:
= The sensors are damaged, covered or dirty
(  page 228).
= The exterior lighting shows a defect.
= The system does not detect a suitable road,
forexample, in tight bends.
= The vehicle is on a construction site.\bThe Active Lane Change Assist sensors adjust
automatically 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
responsibility; you may otherwise fail to recognizedangers (  page 228).

Active Brake Assist

q Function of Active Brake Assist
Active Brake Assist consists of the following func-
tions:
= Collision warning
=Autonomous braking function
= Situation-dependent brake force boosting
= Vehicles with Driving Assistance Package and
Active Steering Assist: Evasive Steering Assist
Active Brake Assist can help you to minimize 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 will sound and the / dis-
tance warning lamp will light up.
On the Assistance menu, an insuPcient distance
1 to the vehicle in front will be displayed in red.
If you further reduce the distance, the vehicle in
front will also be highlighted in red. When the sys- tem detects a risk of collision, red radar waves 2
will appear in front of the vehicle.\bVehicles with PRE-SAFE n
: depending on the
country, an additional haptic warning will occur in the form of slight, repeated tension-ing of the seat belt.\bVehicles with active ambient lighting: if Warn-
ing Support is activated, the Active Brake
Assist warning will also be accompanied by
ambient lighting (  page 162).
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In particularly critical situations, Active Brake
Assist can also initiate autonomous braking
directly. In this case, the warning tone and the
/ distance warning lamp will occur at the
same time as brake application.
If you apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent brake force boosting will
occur. The brake pressure will increase up to max-
imum full-stop braking if necessary.
Driving and parking253

If autonomous braking or situation-dependent
brake force boosting has occurred, pop up 1 will
appear on the driver\bs display and then automati-
cally disappear aser a short time.
If the autonomous braking function or the situa- tion-dependent brake force boosting is triggered,
additional preventive measures for occupant pro-
tection (PRE-SAFE n
) may also be initiated.
&WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex 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 traPc
situation; do not rely on Active Brake
Assist alone.Be prepared to brake or swerve if neces-
sary.
If Active Brake Assist is deactivated or the func- tions are restricted, e.g. due to activation ofanother driving system, the ê Active Brake
Assist warning lamp will appear on the driver\bs
display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a fault, or if the functions are restricted, the

Canceling brake application by Active Brake Assist You can cancel brake application by Active BrakeAssist at any time by:
= Fully depressing the accelerator pedal or acti-
vating kickdown.
= Releasing the brake pedal.
Active Brake Assist may cancel brake application
when one of the following conditions is fulNlled:
= you maneuver to avoid the obstacle
= there is no longer a risk of collision
= an obstacle is no longer detected in front of
your vehicleReaction 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
62 mph (100 km/h)
= Warning for oncoming road users via acoustic

= Autonomous brake application in order to
reduce the severity of an accident
Evasive Steering Assist&WARNING Risk of accident despite Eva-
sive Steering Assist
Evasive Steering Assist cannot always recog-
nize objects or complex traPc situations
clearly.
Moreover, the steering support provided by
Evasive Steering Assist is not suPcient to
avoid a collision.
Always pay careful attention to the traPc
situation; do not rely on Evasive Steering
Assist alone.Be prepared to brake or swerve if neces-
sary.End the support by actively steering in non-critical situations.Drive at an appropriate speed if there
are pedestrians close to the path of your
vehicle.
Evasive Steering Assist has the following charac-
teristics:
= Detection of pedestrians, cyclists and vehi-
cles.
= Assistance through power-assisted steering if
a swerving maneuver is detected.
= Activation by an abrupt steering movement
during a swerving maneuver.
= Assistance during swerving and straightening
of the vehicle.
256Driving and parking

=Reaction from a speed of approximately
12 mph (20 km/h) up to a speed of approx-imately 68 mph (110 km/h).
You can cancel assistance from Evasive Steering
Assist at any time by countersteering.
System limits
Full system performance will not be available for a
short time aser you switch the vehicle on or aser
you drive oM. As long as the functions are restric-
ted, the

them with the information on the digital road map
of the navigation system. It assists you by display-
ing detected speed limits and overtaking restric-
tions in the driver\bs display and in the head-up dis- play. The system can issue a warning when youexceed the maximum permissible speed.
In some countries, the system can provide you with further functions and can warn you when youare approaching pedestrian crossings or whenyou are about to drive past stop signs or red lights
unintentionally.
The camera also detects and analyzes traPc signs
with a restriction indicated by an additional sign (e.g. when wet).
TraPc Sign Assist portrays only selected signs in
the driver\bs display. Actual traPc signs and speed
limits have priority over traPc signs and speed
limits shown in the driver\bs display.
Also observe the following information:
= select a speed adapted to the traPc, sur-
roundings and weather conditions
= observe actual traPc signs
= observe applicable traPc rules and regula-
tionsObserve the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers (  page 228).
Displays in the driver\bs display1Permissible speed2Permissible speed when there is a restriction3Additional sign with restriction
The system can show up to two traPc signs in the
driver\bs display simultaneously. The system always prioritizes displaying speed limits. Up to one traf-
Nc sign with a maximum permissible speed can be
shown in the head-up display. If two speed signs are shown in the driver display, e.g. in the case of
detected restrictions, the value of the les-hand
speed limit 1 is always transmitted to the TEM-
POMAT or Active Distance Assist DISTRONIC for
acceptance and shown in the head-up display.
Examples of traPc signs which can be displayed
TraPc Sign Assist can detect and display following
traPc signs 1:
= speed limits
= end of the speed limit
= overtaking restrictions
= play streets
= recommended speeds
