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
248Battery
Maintenance and care

immediately. Do not drive any further. You
should have all work involvingthe battery car-
ried out at aqualified specialist workshop.
Further information can be foundu nder "ABS"
(
Ypage 62) and under "ESP®"(Ypage 64).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignit ethe highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handlin gthe battery, touc hthe vehicle
body to remove any existin gelectrostatic
build-up.
The flammable gas mix is produced when the
battery is charged or when the vehicle is jump-
started.
Always make sure that neither you nor the bat-
ter ya re electro statically charged. Electrostatic
charging results, for example, from:
Rwearings ynthetic clothing
Rfriction betwee nclothing and the seat
Rdraggingorp ushingthe battery across carpet
flooring or any other synthetic materials
Rrubbingt he battery with cloths or towels.
Comply with the followings afetyprecautions
and tak eprotective measuresw hen handling
batteries.
Risk of explosion.E xplosive oxyhy-
drogen is produced when batteries
are being charged. Only charge bat-
teries in well-ventilated areas.
Fire ,open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Batter yacid is caustic. Avoid con-
tac twith the skin ,eyes or clothing.
Wear acid-proof protective gloves.I f
skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and the nclean the affec-
ted areas with water .Consult adoc-
tor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can splash
int oy our eyes. Rinse acid splashes
to the eyes immediately with clean water and contac
tadoctor immedi-
ately.
Keep children at asafe distance.
Children are not able to assess the
danger sposed by batteries and
acid.
When handlin gbatteries, observe
the safetyp recautionsand special
protective measuresc ontained in
this Operator's Manual.
HEnvironmental note
Batteries contain dangerous
