Comply with the foll owing safety precautions
and take protective measures when handlin g
batteries.
Risk of explos ion. Explosive oxyhy-
drogen isproduced when batteries
are bein g charge d.Only charge bat-
teries in well- ventilated areas.
Fire, open flames and smoking are
therefore pro hibited when working
on the battery. Avoid creating
sparks.
Battery acid iscaustic. Avoid con-
tact with the skin, eyes or clothing.
Wear acid-proof protective gloves. If
skin or clothes are splashed with
acid, neutr alize the splashes imme-
diat elywith soapy water or an acid
neutr alizer, and then clean the affec-
ted areas with water. Consult a doc-
tor ifnecessary.
Wear eye protection. When mixing
water and acid, the liquidcan splash
into your eyes. Rinse acid splashes
to the eyes immediately with clean
water and contact a doctor immedi-
ately.
Keep ch ildren at a safe distance.
Childr en are not ableto assess the
dangers posed bybatteries and
acid.
When handlin g batteries, observe
the safety precautions and special
protective measures contained in
th is Operator's Manual.
HEnvironmental note
Batteries contain dangerous
substances. It isagainst the
law to dispose of them with
the household rubbish. They
must becollec ted separate ly
and recycled to protect the
environment.
Dispose of batteries inan
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
co llec tion point for used bat-
teries. Observe the foll
owing notes:
RRecharge the battery more frequently, if you:
-predominantly drive short distances
-predominantly drive at low outside temper-
atures
-leave the vehicle parked for a lengthy
period
In order for the batteries to achieve their max-
imum possible service life, they must always
be sufficiently charge d.
RConsult an authorized Mercedes-Benz Com-
mercial Van Centerifyou wish to leave your
vehicle parked for a long period of time.
RWhen you park the vehicle, remove the key if
you do not require any electrical consumers.
The vehicle will then use very little energy,
thus conserving battery power.
RIf your vehicle requires jump-starting, or if you
wish to provide jump-starting assistance to
another vehicle, only use the jump-starting
connection point in the engine compartment
(
Ypage 272).
RHave the battery removed at a qualified spe-
cialist workshop.
Installation locations
Your vehicle may be equipped with three bat-
teries, depending on the equipment version:
RStarter battery in the seat base of the right-
hand front seat
RAuxiliary battery inthe seat base of the right-
hand front seat
RAdditional battery inthe seat base of the left-
hand front seat

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

Maintenance and care

installed in the vehicle. The vehicle's elec-
tronics system may otherwise be damaged.
!Only charge the battery using the jump-
starting connection point.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Only this device permits the charging
of the battery in its installed position. Contact an
authorized Mercedes-Benz Commercial Van
Center for information and availability. Read the
operating instructions for your charger before
charging the battery.
Recharge the battery more frequently if you use the vehicle mainly for short trips and/or drive at
low outside temperatures.
Only charge the installed battery with a battery
charger that has been tested and approved by
Mercedes-Benz, using the jump-start connec-
tion point in the engine compartment.
XConnect the battery charger to the positive
terminal and ground terminal in the same
order as when connecting the donor battery in
the jump-starting procedure (
Ypage 272).
iIf a battery is not installed and not in service,
you should charge it every three months. This
will counter self-discharging and prevent bat-
tery damage.
Care
!
Dirty battery clamps and battery surfaces
cause leak currents which 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 a commer-
cially available cleaning product.

detachable parts as steps, you could:
Rslip and/or fall
Rdamage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a suita-
ble ladder.
!Do not use the lower sliding door guide (car-
riage) as a step. Otherwise, you could damage
the paneling and/or the sliding door mecha-
nism.
!For cleaning your vehicle, do not use any of
the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective films
with hard objects, e.g. a ring or ice scraper.
You could otherwise scratch or damage the
surfaces and protective film.
!Do not park your vehicle for a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.

272Jump-starting
Breakdo wn assis tance

!Vehicles with a gasoline engine:avoid
repeated and lengthy starting attempts. Oth-
erwise, the catalytic converter could be dam-
aged by non-combusted fuel.
If the indicator and warning lamps in the instru-
ment cluster do not light up at low tempera-
tures, the discharged battery may have frozen.
In this case you may neither charge the battery
nor jump-start the vehicle. The service life of a
thawed battery may be shorter. Start-up behav-
ior may deteriorate, in particular at low temper-
atures. Have the thawed battery checked at a
qualified specialist workshop.
Do not use a rapid charging device to start the
vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another
vehicle or from a donor battery using jumper
cables. For this purpose, the vehicle has a jump-
starting connection point in the engine com-
partment.
When jump-starting, observe the following
points:
RThe battery is not accessible in all vehicles. If
the other vehicle's battery is not accessible,
jump-start the vehicle using a donor battery
or a jump-starting device.
RYou may only jump-start the vehicle when the
engine and exhaust system are cold.
Rdo not start the engine if the battery is frozen.
Let the battery thaw first.
Rjump-starting may only be performed from
batteries with a nominal voltage of 12 V.
Ronly use jumper cables that have a sufficient
cross-section and insulated terminal clamps.
Rif the battery is fully discharged, attach the
battery of another vehicle for a few minutes
before attempting to start. This charges the
empty battery a little.
Rmake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rbare parts of the terminal clamps do not come into contact with other metal parts while the
jumper cables are connected to the battery.
Rthe jumper cables cannot come into contact
with parts such as the V-belt pulley or the fan.
These parts move when the engine is started
and while it is running.
Jumper cables and further information regarding
jump starting can be obtained at any qualified
specialist workshop.
Before connecting the jumper cables
