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.

Maintenance
General notes
HEnvironmental note
Observe measures to protect the environ-
ment when working on the vehicle. You must
observe the legal requirements when dispos-
ing of service products, e.g. engine oil. This
also includes all components, e.g. filters,
which have come into contact with service
products. Any qualified specialist workshop
can provide information about this.
Dispose of empty containers, cleaning cloths
and care products in an environmentally
responsible manner. Comply with the instruc-
tions for use of the care products.
Do not run the engine for longer than neces-
sary when the vehicle is stationary.
Before carrying out maintenance measures and
repairs, you must read the following documents
relating to maintenance measures and repairs:
Rrelevant sections of the technical documen-
tation such as the Operator's Manual and
workshop information
Rlegal stipulations such as work safety regula-
tions and accident prevention regulations
While working under the vehicle, you must
secure the vehicle on jack stands with sufficient load capacity.
Never use a vehicle jack instead of stands. The
jack is designed only to raise the vehicle for a
short time when changing a wheel. It is not
suited for performing maintenance work under
the vehicle.
Please also refer to the notes about qualified
specialist workshops (
Ypage 31).
The scope and regularity of the inspection and
maintenance work primarily depend on the
often diverse operating conditions. Specialist
knowledge beyond the scope of this Operator's
Manual is required when carrying out testing
and maintenance work. This work should only be
carried out by trained staff.
The vehicle Maintenance Booklet describes the scope and frequency of maintenance work and
contains additional notes on the Limited War-
ranty. You will find information about service
products approved by Mercede s-Benz a
ndcapacities under "Service products and capaci-
ties" (
Ypage 306)
Maintenance services must be carried out in
accordance with the provisions and recommen- dations in the Maintenance Booklet. Not doing
so could void the warranty claim and lead to
refusal of goodwill gestures after the manufac-
turer has submitted a damage report.
Observe the information under "Mercedes-Benz
genuine parts" (
Ypage 33).
Service interval display
General notes
The service interval display informs you of the
next service due date. Information on the type of
service and service intervals can be found in the
Maintenance Booklet.
iThe service interval display does not provide
information about the engine oil level. The
service interval display should therefore not
be confused with the engine oil level display.
For example, the display shows one of the fol-
lowing service messages for a few seconds:
RService A in .. days
RService A Dueor Service A Due
RServ. A Exceed. by .. Days
Then either the remaining time or distance until
the next service due date is displayed. If the
service due date has been exceeded, the
elapsed time or distance traveled after the over-
due service date is shown. The letter in the dis-
play message indicates which service is due. A
stands for a minor service andBfor a major ser-
vice.
A qualified specialist workshop, e.g. an author-
ized Mercedes-Benz Commercial Van Center,
will reset the service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
The prescribed service interval is based on nor- mal vehicle use. Service work will need to be
performed more frequently than prescribed if
the vehicle is operated under more arduous con-
ditions or with higher loads. Such arduous con-
ditions include:
Rregular city driving with frequent intermediate
stops
Rdriving predominantly short distances

Charging
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
If the indicator/warning lamps do not light up in the instrument cluster when temperatures are
low, it is probably because the discharged bat-
tery has frozen. Should this be the case, do not
jump-start the vehicle or charge the battery. The
service life of a thawed battery may be shorter. Start-up behavior may deteriorate, in particular
at low temperatures. Have the thawed battery
checked at a qualified specialist workshop.
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
!Only charge the installed battery with a bat-
tery charger that has been tested and
approved by Mercedes-Benz. This device
allows the battery to be charged when it is
