Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Loading guidelines
Important safety notes
GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, striking vehicle occupants. This also
applies to:
Rluggage or loads
Rseats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of a braking maneuver or abrupt change
in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove a
seat, store it preferably outside the vehicle.
GWARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and braking characteris-
tics. There is a risk of an accident.
Always make sure that the center of gravity of
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When the permissible wheel loads, axle loads
and/or the maximum permissible gross vehi-
cle weight are exceeded, driving safety is
compromised. The handling as well as steer-
ing and braking characteristics may be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is a risk of
an accident.
When transporting a load, always observe the
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (including occupants).
!If you are using a roof carrier, observe the
maximum roof load and maximum roof carrier
load.
RDo not stack luggage or loads higher than the
backrests.
RObjects to be transported should preferably
be stowed in the cargo compartment.
RWhen transporting luggage, always use the
cargo tie-down rings for securing loads and a
cargo net, if installed.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
When using suitable load securing aids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on dis-
card criteria contained therein.
Load securing aids or tie downs must not be
used if:
Ridentification marks are missing or illegible
Rthere are yarn breakages, damage to bearing seams or other signs of tearing
Rthere are signs of shearing, deformation,
pinching or other damage
Rthere is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be replaced.
If you use load securing aids or tie downs which are worn out, the load may not be sufficiently
secured and could cause damage to property.
244Loading guidelines
Transporting loads

Also observe the safety information in the load-
ing directions (Ypage 244).
XFill spaces between the load and the cargo
compartment walls or wheel housings (form-
locking). Use rigid load securing aids, such as
wedges, wooden fixings or padding.
XAttach secured and stabilized loads in all
directions to the cargo tie-down rings and the
guide rails in the rear.
Only use tie downs, such as lashing nets and
lashing straps, that have been tested in
accordance with current standards.
When securing a load, always use the closest cargo tie-down rings and pad sharp edges for
protection.
Cargo tie-down points (example: Cargo Van)
Fixed cargo tie-down points on the floor
:
Guide/load rails
;Cargo tie-down rings
If your vehicle is equipped with guide/loading
rails :in the floor, you can place lashing rods
directly in front of and behind the load. The lash-
ing rods directly absorb the potential shifting
forces.
Securing loads on the cargo compartment floor
by lashing them down is only recommended for lightweight loads. Place non-slip mats (anti-slip
mats) under the load to increase load security.
Lashing straps
Important safety notes
GWARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction, brak- ing maneuvers or an accident:
Rthe cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
Rthe load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
!Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the max-
imum loading capacity of the weakest cargo
tie-down point into account.
If you brake hard, for example, the forces act-
ing could be up to several times the weight
force of the load. Always use multiple cargo
tie-down points in order to distribute the force absorption. Load the anchorages evenly.
Always observe the operating instructions or the
notes of the la shing strap ma

nufacturer for the
operation of the lashing strap.
Securing loads on the cargo compartment floor
by lashing them down is only recommended for
lightweight loads. Place non-slip mats (anti-slip
mats) under the load to increase load security.

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.
260Battery
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 274).
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.
