service interval displayshould therefore not
be confused with the engine oil level display.
For example, the displays hows one of the fol-
lowing service messages for afew seconds:
RNext Service Ain..Days
RServiceADueorService ADue
RServ. AExceed. 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
elapsedt ime 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 foraminor service and Bforam ajor ser-
vice.
Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Benz Commercial Van Center,
will reset the service interval displaya fter 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 arduousc on-
ditions or with higher loads. Such arduousc on-
ditions include:
Rregularc ity driving with frequent intermediate
stops
Rdriving predominantly short distances
Rfrequent operation in mountainous terrain or
on poor road surfaces
Rleaving the engine idling for long periods on a frequent basis
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for example,
replaced more frequently. Under more arduous
operating conditions, the tires must be checked more often. Further information can be obtained
at aq ualified specialist workshop, e.g. an
authorized Mercedes-Benz Commercial Van
Center.

Battery
Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at aqualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilari nci-
dent, contact aqualified specialist workshop

Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous

You can only estimate the oil consumption after

Coolan tadditive with corrosion and
antifreeze protection
!Use only approved antifreeze/corrosion
inhibitor that complies withMBS pecification
300Service products and capacities
Technical data
for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may causedamage to the cool-
ant system and reduce the engine' sservice
life
.
The coolant is amixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
Rcorrosion protection
Rantifreeze protection
Rraises the boiling point
When the vehicl eisfirst delivered, it is filled with
ac oolant mixture that ensure sadequate anti-
freeze and corrosion protection. Coolant must
remai ninthe engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved antifreeze and corrosion
inhibitor that complies with the Mercedes-Benz Specifications for Service Products.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
Check the antifreeze/corrosio ninhibitor con-
centration in the coolant every six months.
The percentag eofcorrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing downt o
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡[-45 †]) .Otherwise, hea twilln ot be
dissipated as effectively.
If ther ehasbeen coolant loss, do not refill only
with water. If the vehicl ehaslost coolant, add
equa lparts water and antifreeze/corrosion
inhibitor. The water used as part of the coolant
mixture must fulfil lcertain requirements; these
are usuall yfulfille dbyd rinking water. If the
water quality is not sufficient, yo umusttrea tthe

Important safety notes
The climate control system of you rvehicle is fil-
led with the refrigerant R ‑134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!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 damaged.
Maintenance work such as adding refrigerant or
replacing components may only be carried out
by aq ualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
need to be respected.
All work on the climate control system should
always be carried out at qualified specialist
