Maintenance
General notes
H
Environmental note
Observe measures to protect the environ-
ment when working on the vehicle. You
must observe the legal requirements when
disposing 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 environmen-
tally responsible manner. Comply with the
instructions 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 docu-
ments relating to maintenance measures and
repairs:
R relevant sections of the technical documen-
tation such as the Operator's Manual and
workshop information
R legal stipulations such as work safety regu-
lations and accident prevention regulations
While working under the vehicle, you must
secure the vehicle on jack stands with suffi-
cient 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
(Y page 32).
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 Opera-
tor'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
Warranty. You will find information about ser- vice products approved by Mercedes-Benz and
capacities under "Service products and capaci-
ties"

(Y page 305)
Maintenance services must be carried out in
accordance with the provisions and recom-
mendations in the Maintenance Booklet. Not
doing so could void the warranty claim and
lead to refusal of goodwill gestures after the
manufacturer has submitted a damage report.
Observe the information under "Mercedes-
Benz genuine parts" (Y page 34). 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.
i The service interval display does not pro-
vide information about the engine oil level.
The service interval display should therefore
not be confused with the engine oil level dis-
play.
For example, the display shows one of the fol-
lowing service messages for a few seconds: R Service A in .. days
R Service A Due or Service A Due
R Serv. 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
overdue service date is shown. The letter in
the display message indicates which service is
due. A stands for a minor service and B for a
major service.
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 mainte-
nance work, for example. Maintenance

Maintenance and care Z

Cleaning the steering wheel and selec-
tor lever
X
Thoroughly wipe with a damp cloth.
X Vehicles with leather upholstery: after
cleaning, use leather care agents that have
been recommended and approved by
Mercedes-Benz.
Cleaning the trim elements !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
X Wipe the trim elements with a damp, lint-
free cloth, e.g. a microfiber cloth.
X Heavy soiling: use care products and
cleaning agents recommended and
approved by Mercedes-Benz.
Cleaning the seat covers !
Do not use microfiber cloths to clean gen-
uine leather or artificial leather covers. If
used often, a microfiber cloth can damage
the cover.
! Clean:
R artificial leather covers with a cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid.
R cloth covers with a microfiber cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid. Wipe entire
seat sections carefully to avoid leaving
visible lines. Leave the seat to dry after-
wards. Cleaning results depend on the
type of dirt and how long it has been
there.
R genuine leather covers carefully with a
damp cloth, then wipe the covers down
with a dry cloth. Make sure that the
leather does not become soaked. Other-
wise, the leather could become rough or
cracked. Only use leather care agents
that have been tested and approved by
Mercedes-Benz. You can obtain these
from a qualified specialist workshop.
i Please keep in mind that:
R leather covers are a natural product and,
as such, are subject to a natural aging process. Leather may react differently,
e.g. increased wrinkling, to certain envi-
ronmental influences (such as high
humidity or intense heat).
R regular care is essential to make sure that
the appearance and comfort of the covers
are retained over time.
To clean genuine leather covers: X Remove any dust, crumbs etc. If necessary,
carefully vacuum-clean the seat covers.
X Carefully wipe the leather seat covers with a
damp cloth.
X Wipe over again with a dry cloth.
Make sure that the leather does not become
soaked, especially perforated parts.
X Then treat the leather seats with a leather
care foam.
Only use leather care agents that have been
tested and approved by Mercedes-Benz.
Observe the manufacturer's instructions.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident. This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above
176 ‡
(80 †) or in direct sunlight.
Remove any stains or dirt immediately. This
will avoid residue or damage. X Use clean, lukewarm water and soap solu-
tion.
Cleaning the headliner and carpets X
Headliner: if it is very dirty, use a soft brush
or dry shampoo.
X Carpets: use the carpet and textile cleaning
agents recommended and approved by
Mercedes-Benz. Care

the coolant system and reduce the engine's
service life.
The coolant is a mixture of water and anti-
freeze and corrosion inhibitor. It performs the
following tasks:
R Anti-corrosion protection
R Antifreeze protection
R Raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze/corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure anti-corrosion protection and
a higher boiling point, even in countries with
high outside temperatures.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least
50%. This way, the engine cooling
system is protected against freezing down
to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not
be dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the require-
ments in the Mercedes-Benz Specifications for
Service Products Sheet Number 325.
More information can be obtained at any quali-
fied specialist workshop.

) Climate control system refrigerants
Important safety notes The climate control system of your vehicle is
filled with the refrigerant R ‑134a.
The warning label for the refrigerant being
used can be found on the radiator cross mem-
ber.
! Only the refrigerant R‑134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant. Otherwise,
the climate control system may be dam-
aged.
Maintenance work such as adding refrigerant
or replacing components may only be carried
out by a qualified specialist workshop. All
applicable regulations thereto and the SAE
standard J639 must be adhered to.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
