In the event of an accident, have a damaged
cargo compartment floor or loading area, the
cargo tie-down rings and the tie down checked
at a specialist workshop. Otherwise, the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur-ing a load" (
Ypage 246) and "Load distribution"
(Ypage 245) sections.
You will find information about the maximum
roof load under "Cargo tie-down points and car-
rier systems" (
Ypage 314). You will find infor-
mation about roof carriers under "Carrier sys-
tems" (
Ypage 250).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformation and crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 282).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for your vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or optional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 245).
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
XSecure the load (Ypage 246).
Observe the legal requirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 282).
XDriving style: adapt your driving style
according to the vehicle load.
Load distribution
General notes
!
Excessive loads on individual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.

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 306).
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 (

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 306)
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
Maintenance259
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.
