uations, PRE-SAFE
®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park-
ing space with assistance from Parking Pilot,
PRE-SAFE ®
PLUS will not apply the brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta- tionary
- the seat belts are pre-tensioned
The PRE-SAFE ®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if Distance Pilot DISTRONIC indicates an
intention to pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat. Children are
generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
R be sure to observe the instructions and safety
notes on the automatic front-passenger front
airbag deactivation system (Y page 50). Children in the vehicle

Active Brake Assist
General information i
Observe the "Important safety notes" sec-
tion (Y page 68).
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and Adaptive Brake Assist.
Active Brake Assist can help you to minimise the
risk of a collision with the vehicle travelling in
front or reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk of collision, you will be warned visually and
acoustically. If you do not react to the visual and
audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist of the Active Brake Assist sys- tem supports you.
Important safety notes In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after servicing is carried out
on the Active Brake Assist system
Please observe the information in the section on running-in the vehicle (Y page 147).
Following damage to the front end of the vehicle, have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where no damage to the front of the
vehicle is visible.
Activating/deactivating Active Brake Assist is automatically active after
switching on the ignition.
You can activate or deactivate Active Brake
Assist (Y page 250) in the on-board computer.
When the system is deactivated, the distance warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the
æ
symbol appears in the assistance graphic dis-
play.
If DSR (Y page 227) is activated, Active Brake
Assist is deactivated.
Distance warning function General information
The distance warning function can help you to
minimise the risk of collision with the vehicle in
front or reduce the effects of such a collision. If the distance warning function detects a risk of
collision with the vehicle in front, you will be
warned visually and acoustically.
Important safety notes i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 68). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone. 70
Driving safety systemsSafety
Function
The distance warning function issues a warning
at speeds:
R of approximately 30 km/h or more, if, over
several seconds, the distance maintained to
the vehicle travelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7 km/h or more, if you rap-
idly approach a vehicle in front. An intermit-
tent warning tone will then sound and the
· distance warning lamp will light up in the
instrument cluster.
X Brake immediately to increase the distance
from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
Due to the nature of the system, certain com-
plex but non-critical driving conditions may also
cause the system to display a warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta- tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function is available in
the following speed ranges:
R 7 - 105 km/h for moving objects
R 7 - 50 km/h for stationary objects
Due to the nature of the system, complex but
non-critical driving conditions may also cause
the autonomous braking function to engage.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page 56).Adaptive Brake Assist General information
i Observe the "Important safety notes" sec-
tion (Y page 68).
With the help of the radar sensor system, Adap-
tive Brake Assist can detect obstacles that are in the path of your vehicle for an extended period
of time.
If Adaptive Brake Assist detects a risk of colli-
sion with the vehicle in front, it calculates the
brake pressure necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive Brake
Assist automatically increases the brake pres-
sure to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
7 km/h. It uses the radar sensor system to
assess the traffic situation.
Up to a speed of approximately 250 km/h,
Adaptive Brake Assist is capable of reacting to
moving objects that have already been detected
as such at least once over the period of obser-
vation.
Up to a speed of approximately 70 km/h, Adap-
tive Brake Assist reacts to stationary obstacles.
If Adaptive Brake Assist demands a particularly
high braking force, preventative passenger pro- tection measures (PRE-SAFE ®
) are activated
simultaneously (Y page 56).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R the risk of collision with the vehicle in front
has passed
R no obstacle is detected in the path of your
vehicle
Adaptive Brake Assist is then deactivated.

WARNING
Active Brake Assist with cross-traffic function will initially brake your vehicle by a partial
application of the brakes if a danger of colli-
sion is detected. There may be a collision
unless you brake yourself. Even after subse-
quent full application of the brakes a collision
cannot always be avoided, particularly when
approaching at too high a speed. There is a
risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
If you partially apply the brakes, the vehicle is
braked with up to 50% of the full brake pressure. G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify objects and
complex traffic situations.
In such cases, Active Brake Assist with cross-
traffic function might:
R issue an unnecessary warning or engage
R neither issue a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially if Active Brake Assist with cross-traffic func-
tion alerts you. Terminate the intervention in a
non-critical driving situation. G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify people, partic-
ularly if they are moving. Active Brake Assist
with cross-traffic function cannot intervene in
these cases. There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially if Active Brake Assist with cross-traffic func-
tion alerts you. To maintain the appropriate distance to the
vehicle in front and thus prevent a collision, you
must apply the brakes yourself. G
WARNING
Active Brake Assist with cross-traffic function does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As a result, Active Brake Assist with cross-
traffic function may not warn you or engage in
all critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detection can be impaired.
Detection by the radar sensor system is also
impaired in the following situations:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R vehicles quickly moving into the radar sensor
system detection range
Detection by the camera system is also impaired in the following situations:
R dirt on the camera or if the camera is covered
R glare on the camera system, e.g. from the sun
being low in the sky
R darkness
R if:
- pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special cloth-
ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a person is not distin-
guishable from the background
Following damage to the front end of the vehicle, have the configuration and operation of the 76
Driving safety systemsSafety
radar sensors checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where no damage to the front of the
vehicle is visible.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function X
To activate or deactivate: activate or deac-
tivate Active Brake Assist with cross-traffic
function using the on-board computer
(Y page 250).
If the Active Brake Assist with cross-traffic
function is deactivated, the æsymbol
appears in the multifunction display.
If you have activated DSR (Y page 227), the
Active Brake Assist with cross-traffic function is
deactivated.
This function issues a warning:
R at a speed of approximately 30 km/h or
higher, the distance maintained to the vehicle
travelling in front is insufficient for several
seconds.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7 km/h or more,
you rapidly approach a vehicle in front or a
pedestrian
An intermittent warning tone will then sound
and the ·distance warning lamp will light
up on the instrument cluster.
X Brake immediately to defuse the situation.
or
X Take evasive action provided it is safe to do
so.
Active Brake Assist with cross-traffic function
can also brake the vehicle automatically under
the following conditions:
R the driver and front passenger have their seat
belts fastened
and
R the vehicle speed is between approximately
7 km/h and 200 km/h Up to a speed of approximately 70 km/h, Active
Brake Assist with cross-traffic function may
react to:
R stationary objects in the path of your vehicle,
such as stopped or parked vehicles
R pedestrians in the path of your vehicle
i If an increased danger of collision exists,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 56).
If the risk of collision remains and you do not
brake, take evasive action or accelerate quickly,
the vehicle may perform automatic braking up to
the point of a full brake application. An auto-
matic full brake application is not performed
until immediately prior to an imminent accident.
If you apply the brake yourself in a critical sit-
uation or during autonomous braking, braking
assistance is provided according to the situa-
tion. If necessary, this increases the brake pres-
sure up to full brake application.
To avoid a collision, Active Brake Assist with
cross-traffic function calculates the brake force
necessary if:
R you approach an obstacle and
R Active Brake Assist with cross-traffic function
has detected a risk of a collision
When driving at a speed under30 km/h: if
you depress the brake pedal, Active Brake
Assist with cross-traffic function is activated.
Braking assistance from Active Brake Assist
with cross-traffic function is carried out at the
last possible moment.
When driving at a speed above30 km/h: if
you depress the brake pedal sharply, Active
Brake Assist with cross-traffic function auto-
matically increases the brake pressure to a
degree suited to the traffic situation.
Active Brake Assist with cross-traffic function
provides braking assistance in hazardous situa-
tions with vehicles in front within a speed range
between 7 km/h and 250 km/h. Driving safety systems
