PRE-SAFE®PLUS does not intervene if the
vehicle is backing up.
When driving, or when parking or exiting a
parking space with assistance from Active
Parking Assist, 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 meas-
ures depending on the hazardous situation
detected:
Rif the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
Rif the radar sensor system detects that a
rear-end collision is imminent:
-the brake pressure is increased if the
driver applies the brakes when the vehi-
cle is stationary.
-the seat belts are pre-tensioned.
The PRE-SAFE
®PLUS braking application is
canceled:
Rif the accelerator pedal is depressed when
a gear is engaged
Rif the risk of a collision passes or is no lon- ger detected
Rif DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored.
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the elec-
trically adjustable steering wheel is raised
Rthe engine is switched off and the fuel sup- ply is cut off
Rvehicles with mbrace: automatic emer-
gency call
Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
Rbe sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
Rbe sure to observe the instructions and
safety notes on the "Occupant Classifica-
tion System (OCS)" (
Ypage 51)
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.

Safety

Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
BAS PLUS (Brake Assist System
PLUS) with Cross-Traffic Assist
General information
BAS PLUS can help you to minimize the risk of
a collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
iPay attention to the important safety
notes in the "Driving safety systems" sec-
tion (
Ypage 67).
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational.
With the help of a sensor system and a cam-
era system, BAS PLUS can detect obstacles:
Rthat are in the path of your vehicle for an
extended period of time
Rthat cross the path of your vehicle
In addition, pedestrians in the path of your
vehicle can be detected.
BAS PLUS detects pedestrians by using typi-
cal characteristics such as the body contours
and posture of a person standing upright.
If the radar sensor system or the camera sys-
tem is malfunctioning, BAS PLUS functions
are restricted or no longer available. The
brake system is still available with complete
brake boosting effect and BAS.
iObserve the restrictions described in the
"Important safety notes" sec-
tion“ (
Ypage 68).
Important safety notes
GWARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
Rintervene unnecessarily
Rnot intervene
68Driving safety systems
Safety

BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within
a speed range between 4 mph (7 km/h) and
155 mph (250 km/h).
At speeds of up to approximately 44 mph
(70 km/h), BAS PLUS can react to:
Rstationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
Robjects crossing your path and that are
recognized in the detection range of the
sensors
iIf BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE
®PLUS) are
activated simultaneously (
Ypage 59).
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again, if:
Ryou release the brake pedal.
Rthere is no longer a risk of collision.
Rno obstacle is detected in front of your
vehicle.
Ryou depress the accelerator pedal
Ryou activate kickdown.
COLLISION PREVENTION ASSIST
PLUS
General information
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous braking function and adaptive
Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end
collision with a vehicle ahead or reduce the
effects of such a collision. If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a 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, the COLLISION
PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Important safety notes
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rnew vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Observe the important safety notes in the
"Breaking-in notes" section (
Ypage 152).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Switching on/off
The COLLISION PREVENTION ASSIST PLUS is
automatically active after switching on the
ignition.
You can activate or deactivate COLLISION
PREVENTION ASSIST PLUS in the on-board
computer (
Ypage 252). When deactivated,
the distance warning function and the auton-
omous braking function are also deactivated.
70Driving safety systems
Safety

Vehicles with DISTRONIC PLUS:the auton-
omous braking function is available in the fol- lowing speed ranges:
R4 - 124 mph (7 - 200 km/h) for moving
objects
R4 - 31 mph (7 - 50 km/h) for stationary
objects
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the Autonomous Brak-
ing Function to intervene.
If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously (
Ypage 59).
Adaptive Brake Assist
General information
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
With the help of adaptive Brake Assist, the
distance warning signal 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 col-
lision with the vehicle in front, it calculates
the braking force necessary to avoid a colli-
sion. If you apply the brakes forcefully, adap-
tive Brake Assist will automatically increase
the braking force to a level suitable for the
traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
Up to a speed of approximately 155 mph
(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 observation.
Up to a speed of approximately 44 mph
(70 km/h), adaptive Brake Assist reacts to
stationary obstacles. If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously (
Ypage 59). On
vehicles with the Driving Assistance package,
preventive passenger pro tection me
asures
(PRE-SAFE®PLUS) are triggered (Ypage 59).
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
Ryou release the brake pedal.
Rthere is no longer any danger of a collision.
Rno obstacle is detected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems (
Ypage 67).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
72Driving safety systems
Safety

Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause Brake Assist to inter-
vene.
If adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
ESP
®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP
®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
ETS traction control is part of ESP
®. On vehi-
cles with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
If the å ESP®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP
®warning lamp lights up con-
tinuously, ESP®is not available due to a mal-
function.
Observe the information on warning lamps
(
Ypage 296) and display messages which
may be shown in the instrument cluster
(
Ypage 258).
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Characteristics of ESP®
General information
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP
®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning
lamp flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts automati-
cally when the driver wants to pull away again.

collision. If PRE-SAFE®Brake has detected a
risk of collision, you will be warned visually
and acoustically as well as by automatic brak-
ing.
iPay attention to the important safety
notes in the "Driving safety systems" sec-
tion (
Ypage 67).
PRE‑SAFE
®Brake is only available in vehicles
with the Driving Assistance Plus package.
For PRE-SAFE
®Brake to assist you when driv-
ing, the radar sensor system and the camera system must be switched on and be opera-
tional.
With the help of the radar sensor system and
the camera system, PRE-SAFE
®Brake can
detect obstacles that are in front of your vehi-
cle for an extended period of time.
In addition, pedestrians in the path of your
vehicle can be detected.
PRE-SAFE
®Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing
upright.
iObserve the restrictions described in the
"Important safety notes" section
(
Ypage 76).
Important safety notes
GWARNING
PRE-SAFE
®Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly 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.
In the event of a partial application of the
brakes, the vehicle is braked with up to 50% of
the full braking pressure.
GWARNING
PRE-SAFE
®Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE
®Brake may:
Rgive an unnecessary warning and then
brake the vehicle
Rnot give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE
®Brake warns you. Terminate the
intervention in a non-critical driving situation.
GWARNING
PRE-SAFE
®Brake cannot always clearly iden-
tify people, especially if they are moving. In
these cases, PRE-SAFE
®Brake cannot inter-
vene. There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE
®Brake warns you.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.
GWARNING
PRE-SAFE
®Brake does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, PRE-SAFE
®Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
