Mobile communications equipment
GWARNING
Operating mobile information systems and
communication devices while driving wil ldis-
tract you from traffic conditions. In addition,
you coul dthen lose control of the vehicle.
There is arisk of an accident.
Only operate these devices whe nthe vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving whe noperat-
ing mobile communication equipment.
Please remember, anavigatio nsystem does not
supply information on the load-bearing capacity
of bridges or the overhead clearance of under-
passes. The drive rremains responsibl efor
safety at al ltimes.
You and others can suffe rhealth-related dam-
age throug helectromagneti cradiation. By using
an exterior antenna, apossibl ehealth risk
caused by electromagneti cfields, as discussed
in scientifi ccircles, is taken into account. Only
have the exterior antenna installed by aqualified
specialist workshop.
Failure to observe the Mercedes-Benz installa-
tion specifications can result in the invalidation of you rvehicle's operating permit.
You wil lfind information on retrofitting electrical
or electronic equipment unde r“Vehicle elec-
tronics” (

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
substances. It is against the
law to dispose of the mwith
the household rubbish. They
must be collected separately and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to aqualified spe-
cialist workshop or aspecial
collection point for used bat-
teries.
Observe the followingn otes:
RRecharge the battery more frequently, if you:
-predominantly drive shortd istances
-predominantly drive at low outside temper-
atures
-leave the vehicle parked for alengthy
period
In order for the batteries to achiev etheir max-
imum possible service life, the ymust always
be sufficiently charged.
RConsult an authorized Mercedes-Ben zCom-
mercial Van Center if you wish to leave your
vehicle parked for along period of time.
RWhen you park the vehicle, remove the Smart-
Key if you do not require any electrical con-
sumers. The vehicle will the nuse very little
energy, thus conserving battery power.
RIf your vehicle requiresj ump-starting, or if you
wish to provide jump-startin gassistanc eto
another vehicle, only use the jump-starting

Charging
GWARNING
Ad ischarged battery can freezeatt empera-
tures below freezing point. When jump-start-
ing th evehicle or chargin gthe battery, gases
can escape from th ebattery. Thereisar isko f
an explosion.
Allow th efroze nbattery to thaw out before
chargin gitorjump-starting.
If th eindicator/warning lamps do no tlight up in
th ei nstrumen tcluste rwhen temperatures are
low, it is probably because th edischarged bat-
tery has frozen.S hould this be th ecase, do not
jump-star tthe vehicle or charge th ebattery. The
servic elife of athawed battery may be shorter.
Start-up behavior may deteriorate, in particular
at low temperatures. Hav ethe thawed battery
checked at aqualified specialist workshop.
GWARNING
During chargin gand jump-starting, explosive
gases can escape from th ebattery. Thereisa

Care
!
Dirt ybattery clamps and battery surfaces
cause leak currentsw hich lead to the batter-
ies discharging.
!Do not use cleaning agents containing fuel.
Cleaning agents containing fuel corrode the
battery housing.
!If dirt gets into the battery cell, battery self-
discharge will increase and the battery may
be damaged.
The following points on battery care must be
observed:
XRegularly check the battery terminals and the
fastening of the negative cable to the chassis
to ensure that they are firmly seated.
XAlways keep the battery terminals and battery
surfaces clean and dry.
XLightly grease the undersides of the battery
terminals with acid-resistant grease.
XOnly clean the battery casing with acommer-
cially availablec leaning product.
