QR code for rescue card
The QR code is secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident, rescue services can use
the QR code to quickly find the appropriate
rescue card for your vehicle. The current res- cue card contains, in a compact form, the
most important information about your vehi-
cle, e.g. the routing of the electric cables.
You can find more information under http:// portal.aftersales.i.daimler.com/public/
content/asportal/en/communication/
informationen_fuer/QRCode.html. Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture This data is of an exclusively technical nature
and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem- ory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Introduction

Important safety notes
!
Make sure that there are no objects in the
footwell or behind the seats. There is a risk that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R vehicles with the Driving Assistance pack-
age: when a driver assistance system inter-
venes powerfully or the radar sensor sys-
tem detects an imminent danger of colli-
sion in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
R the front-passenger seat is adjusted if it is
in an unfavourable position.
R vehicles with a multicontour seat: the air
pressure in the side bolsters of the back-
rest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats, the air pressure in the side
bolsters is reduced again. All settings made
by PRE-SAFE ®
can then be reversed. If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Infor-
mation about the convenience function can
be found under "Belt adjustment"
(Y page 47). PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-
end collision is imminent. In certain hazard-
ous situations, 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 when PRE-SAFE ®
PLUS intervenes.
PRE-SAFE ®
PLUS does not intervene when
reversing.
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. Occupant safety
59Safety Z

PRE-SAFE
®
PLUS takes the following meas-
ures 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 acti-
vated and flash at a higher frequency
- 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
cancelled:
R if the accelerator pedal is depressed when
a gear is engaged
R if the risk of a collision passes or is no lon-
ger detected
R if 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:
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 the electrically adjustable steering wheel is
raised
R the engine is switched off and the fuel sup-
ply is cut off
R vehicles with the Mercedes-Benz emer-
gency 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 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 1.50 m in height is travelling in the
vehicle:
R always 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.
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 always pay attention to the instructions
and safety notes on the automatic front-
passenger front airbag deactivation system (Y page 51). G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is 60
Children in the vehicleSafety

override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for maintaining
the distance to the vehicle in front, for vehicle
speed, for braking in good time, and for stay- ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions and maintain a safe distance from the
vehicle in front. Drive carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tyres and the
road surface. Please pay special attention to
the notes on tyres, recommended minimum
tyre tread depths etc. (Y page 376).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as
effectively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 69). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac- tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 305) and
display messages which may be shown in the
instrument cluster (Y page 267).
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit- uation is over.
X To 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; this serves as a reminder to take extra care while driving. BAS (Brake Assist)
General notes 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 i
Observe the "Important safety notes" sec-
tion (Y page 69). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking. 70
Driving safety systemsSafety

Braking
X
Keep the brake pedal depressed firmly 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 notes BAS PLUS can help you to minimise 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.
i Pay attention to the important safety
notes in the "Driving safety systems" sec-
tion (Y page 69).
BAS PLUS is only available on vehicles with
the Driving Assistance Plus 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:
R that are in the path of your vehicle for an
extended period of time
R that cross the path of your vehicle
In addition, pedestrians in the path of your
vehicle can be detected.
BAS PLUS detects pedestrians using typical
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.
i Observe the restrictions described in the
"Important safety notes" section
(Y page 71). Important safety notes G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
R intervene unnecessarily
R not 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. G
WARNING
BAS PLUS cannot always clearly identify peo- ple, this is especially the case if they are mov-
ing. BAS PLUS cannot intervene in these
cases. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
BAS PLUS does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As a result, BAS PLUS may not intervene 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, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
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 Driving safety systems
71Safety Z

R
a vehicle travelling in front on a different
line
R vehicles quickly moving into the radar sen-
sor system detection range
Detection by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is cov-
ered
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
clothing or other objects
- a pedestrian is concealed by other
objects
- the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Following damage to the windscreen, have
the configuration and operation of the cam-
era system checked at a qualified specialist
workshop.
Function To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R you approach an obstacle and
R BAS PLUS has detected a risk of collision
When driving at a speed under 30 km/h : if
you depress the brake pedal, BAS PLUS is
activated. Braking assistance from BAS PLUS
is carried out at the last possible moment.
When driving at a speed above 30 km/h : if
you depress the brake pedal sharply, BAS PLUS automatically increases the brake pres-
sure to a degree suited to the traffic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within
a speed range between 7 km/h and
250 km/h.
At speeds of up to approximately 70 km/h,
BAS PLUS can react to:
R stationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
R obstacles crossing your path, which move
in the detection range of the sensors and
are recognised by them
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activa-
ted simultaneously.
X Keep 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:
R you release the brake pedal
R there is no longer a risk of collision
R no obstacle is detected in front of your
vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISION PREVENTION ASSIST
PLUS
General notes 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 minimise the risk of a collision
with the vehicle in front or reduce the effects
of such a collision. 72
