Brake fluid
GWAR NING
Service products may be poisonous and haz-
ardous to health. There isa risk of injury.
Comp ly with instructions on the use, storage
and dispo sal of service products on the labels
of the respective original containers. Always
store service products sealed intheir original
containers. Always keep service products out
of the reach of ch ildren.
GWAR NING
Opening the hood when the engine isover-
heated or when there isa fire inthe engine
compartment could expose you to hot gases
or other service products. There isa risk of
injury.
Let an overheated engine cool downbefore
opening the hood. Ifthere isa fire inthe
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool downand
touch only the components describe d in the
foll owin g.
Brake fluid is hazardous to health. Also observe the safety notes under "Service products and
capacities" (
Ypage 304).
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. Ifthe boilin g point of the brake
fluid is too low,vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!If the brake fluid level in the brake fluid res-
ervoir has fallen to the MIN mark or below,
check the brake system immediately for
leaks. Also check the thickness of the brake
linings. Visit a qualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake fluid corrodes paint, plastic and rub-
ber. Ifpaint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every two years at a qualified specialist workshop. Observe the
information regarding brake fluid in the "Service
products and capacities" section (
Ypage 309).

Maintenance and care

Maintenance
General notes
HEnvironmental note
Observe measures to protect the environ-
ment when working on the vehicle. You must
observe the legal requirements when dispos-
ing 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 environmentally
responsible manner. Comply with the instruc-
tions 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 documents
relating to maintenance measures and repairs:
Rrelevant sections of the technical documen-
tation such as the Operator's Manual and
workshop information
Rlegal stipulations such as work safety regula-
tions and accident prevention regulations
While working under the vehicle, you must
secure the vehicle on jack stands with sufficient 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 (
Ypage 31).
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 Operator'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 War-
ranty. You will find information about service
products approved by Mercede s-Benz a
ndcapacities under "Service products and capaci-
ties" (
Ypage 304)
Maintenance services must be carried out in
accordance with the provisions and recommen- dations in the Maintenance Booklet. Not doing
so could void the warranty claim and lead to
refusal of goodwill gestures after the manufac-
turer has submitted a damage report.
Observe the information under "Mercedes-Benz
genuine parts" (
Ypage 33).
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.
iThe service interval display does not provide
information about the engine oil level. The
service interval display should therefore not
be confused with the engine oil level display.
For example, the display shows one of the fol-
lowing service messages for a few seconds:
RService A in .. days
RService A Dueor Service A Due
RServ. 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 over-
due service date is shown. The letter in the dis-
play message indicates which service is due. A
stands for a minor service andBfor a major ser-
vice.
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 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 arduous con-
ditions or with higher loads. Such arduous con-
ditions include:
Rregular city driving with frequent intermediate
stops
Rdriving predominantly short distances
Maintenance257
Maintenance and care
Z

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 a qualified 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 a qualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short 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 a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
Further information can be found under "ABS"
(
Ypage 64) and under "ESP®" (Ypage 65).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
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-
tery are electro statically charged. Electrostatic
charging results, for example, from:
Rwearing synthetic clothing
Rfriction between clothing and the seat
Rdragging or pushing the battery across carpet
flooring or any other synthetic materials
Rrubbing the battery with cloths or towels.
258Battery
Maintenance and care

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:

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
