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
The vehicle is read out by employees of the
service network (including the manufacturer)
using special diagnostic testers. You can
obtain more information there, 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, after 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. 26

Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of
an accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 46)
R adjust their seat and head restraint prop-
erly (Y page 113).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 112).
You also have to make sure that an airbag can inflate properly if deployed (Y page 48).
An airbag supplements a correctly fastened
seat belt. As an additional safety device, the
airbag increases the level of protection for
vehicle occupants in the event of an accident.
For example, if the protection of the seat belt is sufficient in an accident, the airbags are not
deployed. In the event of an accident, only the airbags that increase protection in the rele-
vant accident situation are deployed. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt ten-
sioners and airbags" (Y page 57).42
Occupant safetySafety

cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal.
Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtall cannot wear the
seat belts correctly without a suitable, addi-
tional restraint system. The seat belt cannot
perform its intended protective function if it is not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
ries in the event of an accident, sudden brak-
ing or abrupt changes of direction. There is an increased risk of injury, possibly even fatal.
Secure persons less than 1.50 mtall in a suit-
able restraint system.
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 this Mercedes-Benz
vehicle. The child restraint system must be appropriate to the age, weight and size of
the child.
R always observe the instructions and safety
notes on the automatic front-passenger front airbag deactivation system
(Y
page 51)
R always observe the instructions and safety
notes on "Children in the vehicle" in this
Owner's Manual (Y page 59) in addition
to the child restraint system manufactur-
er's installation instructions G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts can tear or fail, for example in the event of an accident. Modified
seat belt tensioners may be deployed unin-
tentionally or fail to be deployed when
required. There is an increased risk of injury,
possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have
the seat belts checked immediately at a quali- fied specialist workshop.
Mercedes-Benz recommends that you only
use seat belts which have been approved
specifically for your vehicle by Mercedes-
Benz. Otherwise, your vehicle's general oper- ating permit could be invalidated.
Sports seat or AMG Performance seat: this
seat is designed for the standard three-point
seat belt. If you fit another multipoint seat
belt, e.g. sport or racing seat belts, the
restraint system cannot provide the best level of protection. G
WARNING
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of an Occupant safety

accident. This poses an increased risk of
injury or even fatal injury.
Only use the standard three-point seat belt.
Never modify the seat belt system.
Correct seat belt use Observe the safety notes on the seat belt
(Y page 44).
All vehicle occupants must be wearing the
seat belt correctly before beginning the jour-
ney. Also make sure that all vehicle occu-
pants are always wearing the seat belt cor-
rectly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted into the
belt buckle belonging to that seat
R the seat belt is tight across your body
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted
Only then can forces which occur be dis-
tributed across the surface of the seat belt.
R the shoulder section of the belt is always
routed across the centre of your shoulder
The shoulder section of the seat belt should
not touch your neck nor be routed under
your arm. If possible, adjust the seat belt to
the appropriate height.
R the lap belt passes across your lap as
tightly and as low down as possible
The lap belt must always be routed across
your hip joints and never across your abdo-
men. This applies particularly to pregnant
women. If necessary, press the lap belt
down into your hip joints and pull tight with the shoulder section of the belt.
R the seat belt is not routed across sharp,
pointed or fragile objects
If you have such items located on or in your
clothing, e.g. pens, keys or spectacles,
store these in a suitable place.
R only one person is using a seat belt Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat
belt.
R objects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants
Also ensure that no objects are placed
between a person and the seat. e.g. a cush- ion.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe
the "Loading guidelines" for securing objects,
luggage or loads (Y page 316).
Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y
page 44) and the information on the cor-
rect use of the seat belt (Y page 46). Basic illustration
