Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
RReliability
RSafety
RSuitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if an
independent or official approval has been pro-
vided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles.
In some countries, certain parts are only offi-
cially approved for installation or modification if
they comply with legal requirements. All genu-
ine Mercedes-Benz parts satisfy these require-
ments. Make sure that all parts are suitable for
your vehicle.
Always specify the vehicle identification number
(VIN) (
Ypage 305) and engine number when
ordering genuine Mercedes-Benz parts
(
Ypage 306).
QR code for rescue card
The QR Code stickers are affixed to the B-pillar
on the driver's and front-passenger side.
In the event of an accident the rescue services
use the QR Code to quickly find the rescue card for your vehicle. The current rescue card con-
tains the most important information on your
vehicle, e.g. the electric cable routes, in a com-
pact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code.
Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are necessary for
your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made
possible by electronic control units.
Electronic control units contain data storage
systems that can temporarily or permanently save technical information concerning the vehi-
cle's condition, component stress and mainte-
nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the surroundings, for example:
Roperating states of system components (e.g.
fill levels, battery status, tire pressure)
Rstatus messages concerning the vehicle or its
individual components (e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, display of fastened
seat belts)
Rmalfunctions and defects in important system
components (e.g. lights, brakes)
Rinformation about events leading to vehicle
damage
Rsystem responses in special driving situations
(e.g. air bag deployment, intervention of sta-
bility control systems)
Rambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize
vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees or third parties. Services can include
repair services, maintenance processes, war-
ranty cases and quality assurance measures.
The data is read out via the connection for OBD
(European on-board diagnostics) in the vehicle,
which is required by law. The relevant offices in
the service network or third parties collect,
process and use the data. This data documents
the vehicle's technical states, is used to help in
finding malfunctions and improving quality and
is sent to the manufacturer where necessary. Inaddition, the manufacturer is subject to product
liability. The manufacturer needs technical data
from vehicles for this purpose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions y

ourself as part
of the selected equipment.

Restraint system introduction
The restraint system can reduce the risk of vehi-cle 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:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 48)
Rhave the seat and head restraint adjusted
properly (Ypage 85)
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 85).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 50).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only
the air bags that increase protection in that par-
ticular accident situation are deployed. How- ever, seat belts and air bags generally do not
protect against objects penetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 56).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (
Ypage 58).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate a person with
disabilities, contact a Mercedes-Benz Commer-
cial Van Center for details. USA only: contact
our Mercedes-Benz Customer Assistance Cen-
ter on 1‑ 877‑762‑8267 for details.
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec- onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
