=Ø (red): system limits detected
= Ø (white, red hands): "hands on the steer-
ing wheel" prompt\bDuring the transition from active to passive
status, the Ø symbol is shown as enlarged
and "Oashing. When the passive state is
reached, the Ø symbol is displayed in
gray.\bDepending on the selected vehicle settings,
Active Steering Assist may be unavailable.
Steering and touch detection
The driver is required to keep their hands on the steering wheel at all times and be able to inter-
vene at any time to correct the course of the vehi-
cle and keep it in lane. The driver must expect a change from active to passive mode or vice versa at any time.
If the system detects that the driver has not
steered the vehicle for a considerable period of time or has removed their hands from the steeringwheel, display 1 appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to the warning for a
considerable period, the system may initiate an emergency stop (  page 250).
The warning is not issued or is stopped as soon as
the system detects that the driver is touching the
steering wheel or steering.
Touch detection may be limited or may not func-
tion if there is no direct contact between hand
and steering wheel, e.g. when you are wearing
gloves or if there is a steering wheel cover on the steering wheel.
If Active Steering Assist detects that a system limit has been reached, a visual warning is issuedand a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers (  page 228).
System limits
Active Steering Assist has a limited steering tor- que for lateral guidance. In some cases, the steer-
ing intervention is not su"Pcient to keep the vehi-
cle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
= There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, highly variable light condi-
tions or strong shadows on the road.
= There is glare, e.g. from oncoming tra"Pc,
direct sunlight or re"Oections.
= *nsu"Pcient illumination of the road.Driving and parking249

=The windshield is dirty, fogged up, damaged or
covered in the vicinity of the camera, e.g. by a
sticker.
= No, or several, unclear lane markings are pres-
ent for one lane, or the markings change
quickly, such as in a construction area or at intersections.
= The lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= The road is narrow and winding.
= There are obstacles in the lane or projecting
out into the lane, such as object markers.
The system does not provide assistance in the fol-
lowing conditions:
= On tight bends and when turning.
= When crossing intersections.
= At tra"Pc circles or toll stations.
= When towing a trailer.
= When the tire pressure is too low.=Vehicles with E-ACTIVE BODY CONTROL: in
drive program 1 and at lean level 2 and 3&WARNING Risk of accident if Active Steer-
ing Assist unexpectedly stops functioning
If the system limits of Active Steering Assist
are reached there is no guarantee that the
system will remain active or will keep the vehi-
cle in lane.
Always keep your hands on the steering
wheel and observe the tra"Pc carefully.Always steer the vehicle paying attention
to tra"Pc conditions.&WARNING Risk of accident if Active Steer-
ing Assist unexpectedly intervenes
The detection of lane markings and objects
may malfunction and cause unexpected steer-
ing interventions.

Function of Active Emergency Stop Assist
250Driving and parking

If the system detects that the driver has not
steered the vehicle for a considerable period of time or has removed their hands from the steeringwheel, display 1 appears. If the driver still does
not steer the vehicle, or gives no con"Nrmation to
the system, a warning tone sounds in addition to
the visual warning message.
If the driver still does not respond to the warning,
the Beginning Emergency Stop message appears
on the driver display. If the driver still does not
respond, Active Distance Assist DISTRONIC reduces the speed. The vehicle is decelerated in
stages to a standstill.
Depending on the country, at speeds below
40 mph (60 km/h) the hazard warning lights
switch on automatically.
When the vehicle is stationary, the following
actions are carried out:
= The vehicle is secured with the electric park-
ing brake.
= Active Distance Assist DISTRONIC is ended.
= The vehicle is unlocked.=If possible, an emergency call is placed to the
Mercedes-Benz emergency call center.
The driver can cancel the deceleration at any time
by performing one of the following actions:
= Steering
= Braking or accelerating
= Deactivating Active Distance Assist

Active Lane Change Assist

q Function of Active Lane Change Assist
Active Lane Change Assist supports the driver when changing lanes by applying steering torque
if the driver activates a turn signal indicator.
Observe the notes on driving systems and yourresponsibility; you may otherwise fail to recognizedangers (  page 228).
Assistance when changing lanes is provided if all
the following conditions are met:
= You are driving on a freeway or road with mul-
tiple lanes in the direction of travel.
= The neighboring lane is separated by a broken
lane marking.
= No vehicle is detected in the adjacent lane.
= The vehicle speed is between 50 mph
(80 km/h) and 110 mph (180 km/h).
= Active Lane Change Assist is switched on in
the multimedia system.
= Active Steering Assist is activated and active.Driving and parking251

Display on the driver\bs display in the Assistance
menu
1Green arrow: lane change initiated2Red arrow: lane change canceled
If no vehicle is detected in the adjacent lane and a
lane change is permitted, the lane change begins a"ser the driver has activated the turn signal indi-
cator. This is indicated to the driver by a green
"Oashing arrow next to the steering wheel symbol
± . The message Lane Change to the Left , for
example, also appears. If Active Lane Change
Assist is activated with the turn signal indicator,
but a lane change is not possible immediately,
only the green "Oashing arrow appears next to the
steering wheel symbol ±, which remains
green.
As soon as the lane change assistance starts, the
turn signal indicator is automatically activated.
If a lane change is not possible, the arrow is faded out a"ser a few seconds and a new lane change
must be initiated. An immediate lane change is
only possible on freeway sections without speed limits.
In addition, a warning tone may sound, depending
on the situation.&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 although
the 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 tra"Pc conditions and steer
and/or brake if necessary.
System limits
The system limits of Active Steering Assist apply to Active Lane Change Assist (  page 248).
252Driving and parking

The system may also be impaired or may not func-
tion in the following situations:
= The sensors in the rear bumper are dirty, dam-
aged or covered by a sticker or ice and snow, for example.
= The exterior lighting shows a defect.\bThe Active Lane Change Assist sensors adjust
automatically while a certain distance is being
driven a"ser the vehicle has been delivered.
Active Lane Change Assist is unavailable dur-
ing this teach-in process; no arrow appears next to the Active Steering Assist symbol Ø when the turn signal indicator is activa-
ted.

Active Brake Assist

qFunction 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: Eva-
sive Steering Assist and cornering function
Active Brake Assist can help you to minimize the
risk of a collision with vehicles, cyclists or pedes- trians or to reduce the e"Mects of such a collision.
If Active Brake Assist has detected a risk of colli-
sion, a warning tone will sound and the Active
Brake Assist warning lamp / will light up.
In the Assistance menu, an insu"Pcient distance
1 to the vehicle in front is displayed in red. If you
further reduce the distance, the vehicle in front will also be highlighted in red. When the systemdetects a risk of collision, red radar waves 2
appear in front of the vehicle.
Vehicles with PRE-SAFE n
: depending on the coun-
try, an additional haptic warning will occur in the form of slight, repeated tensioning of the seat belt.
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake Assist
can initiate autonomous braking directly. In this
Driving and parking253

case, the warning lamp and warning tone 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 brake force boosting will occur. The brake pressure will increase up to max-
imum full-stop braking if necessary.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers (  page 228).
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 a"ser a short time.
If the autonomous braking function or situation-
dependent brake force boosting is triggered, addi-
tional preventive measures for occupant protec-
tion (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 tra"Pc 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 su"Pciently safe
distance to the vehicle in front, vehicle speed and for braking in good time.
Always pay careful attention to the tra"Pc
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 display message
will appear on the driver\bs display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a malfunction, or if the
functions are restricted, the

Brake immediately or take evasive action, provi-
ded it is safe to do so and the tra"Pc situation
allows this.
Collision warning (vehicles without Driving Assis- tance Package)
The collision warning can aid you in the following
situations with an intermittent warning tone and a warning lamp:
= From approximately 4 mph (7 km/h), if your
vehicle is critically close to a vehicle, cyclist orpedestrian, you will hear an intermittent warn-
ing tone and the distance warning lamp /
will light up on the driver\bs display.
Vehicles 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.

Canceling a brake application of Active Brake
Assist
You can cancel a brake application of Active Brake Assist at any time by:
= sharply depressing the accelerator pedal or
with kickdown
= releasing the brake pedalActive Brake Assist may cancel the brake applica-
tion when one of the following conditions is ful"Nl-
led:
= You maneuver to avoid an obstacle
= There is no longer a risk of collision
= An obstacle is no longer detected in front of
your vehicle
Evasive Steering Assist (only vehicles with Driving
Assistance Package)
Evasive Steering Assist has the following charac-
teristics:
= The ability to detect stationary or moving
pedestrians.
= Assistance through power-assisted steering if
a swerving maneuver is detected.
= Activation through an abrupt steering move-
ment during a swerving maneuver.
= Assistance during swerving and straightening
of the vehicle.
= Reaction from a speed of approximately
12 mph (20 km/h) up to a speed of approx-
imately 43 mph (70 km/h).256Driving and parking

You can prevent the assistance at any time byactively steering.
Cornering function (only vehicles with Driving Assistance Package)
If the system detects a risk of a collision with an
oncoming vehicle when turning across an oncom-
ing lane, autonomous braking can be initiated at
speeds below 9 mph (15 km/h) before you have
le"s the lane in which you are driving.&WARNING Risk of accident despite Eva-
sive Steering Assist
Evasive Steering Assist cannot always recog-
nize objects or complex tra"Pc situations
clearly.
Moreover, the steering support provided by Evasive Steering Assist is not su"Pcient to
avoid a collision.
Always pay careful attention to the tra"Pc
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.
System limits
Full system performance is not available for a
short time a"ser switching on the vehicle or a"ser
driving o"M. Depending on the environmental con-
ditions, it may take a few minutes before full sys-
tem performance is available.
The system may be impaired or may not function,
particularly in the following situations:
= In snow, rain, fog, heavy spray, direct sunlight
or highly variable light conditions, or if there is
glare.
= If the sensors are dirty, fogged up, damaged or
covered.
= If the sensors are impaired due to interference
from other radar sources, e.g. strong radar
re"Oections in parking garages.
= If a loss of tire pressure or a defective tire has
been detected and displayed.
= If DSR is active.
= In complex tra"Pc situations where objects
cannot always be clearly identi"Ned.
= If pedestrians or vehicles move quickly into
the sensor detection range.
= If pedestrians are hidden by other objects.
= If the typical outline of a pedestrian cannot be
distinguished from the background.
= If a pedestrian is not detected as such, e.g.
due to special clothing or other objects.
= If the driver\bs seat belt is not fastened.
= On bends with a tight radius.\bThe Active Brake Assist sensors adjust auto-
matically while a certain distance is being
driven a"ser the vehicle has been delivered.
Active Brake Assist is unavailable or only par-
tially available during the teach-in process.
