The cigarette lighter socket can be used for
accessories with a maximum power consump-
tion of 180 W

(15 A).
If you use the sockets to connect accessories
for long periods when the engine is switched
off, the starter battery may discharge. An
emergency cut-off ensures that the on-board
voltage does not drop too low. If the on-board
voltage is too low, power to the socket is auto-
matically cut. This ensures that there is suffi-
cient power to start the engine. 12 V socket
When the key is turned to position 1 in the
ignition lock, the sockets can be used for accessories with a maximum power consump-
tion of

180 W (15 A).
If you use the sockets for long periods when
the engine is switched off, the starter battery
may discharge. If the on-board voltage is too
low, it might then no longer be possible to
start the engine.
The socket in the center console and the
socket in the side of the cargo compartment
are not automatically deactivated if the on-
board voltage is low. The additional sockets in
the rear compartment are automatically deac-
tivated if the on-board voltage is low.
Additional 12 V sockets may be located in the
rear corner trim next to the tailgate and in the
side trim on the left and right-hand sides.

WARNING
If you operate information and communica-
tion devices while driving, you may be dis-
tracted from the traffic conditions. You
could even lose control of the vehicle. There
is a risk of an accident.
Only operate these devices when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving when operat-
ing mobile communication equipment.
Please remember, a navigation system does
not supply information on the load-bearing
capacity of bridges or the overhead clearance
of underpasses. The driver remains responsi-
ble for safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By
using an exterior antenna, a possible health
risk caused by electromagnetic fields, as dis-
cussed in scientific circles, is taken into
account. Only have the exterior antenna instal-
led by a qualified specialist workshop.
Failure to observe the Mercedes-Benz installa-
tion specifications can result in the invalida-
tion of your vehicle's operating permit.

Stowing and features Z

replaced. If you use load securing aids or tie
downs which are worn out, the load may not
be sufficiently secured and could cause dam-
age to property.
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
anything 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
"Securing a load"
(Y page 244) and "Load dis-
tribution" (Y page 243) sections.
You will find information about the maximum
roof load under "Cargo tie-down points and
carrier systems" (Y page 313). You will find
information about roof carriers under "Carrier
systems" (Y page 249). Before loading
! The anti-slip mats cannot be used for
securing goods and must be replaced when
they show signs of:
R Permanent deformation and crushing
R Crack formation
R Cuts
X Tire pressure: check the tire pressure and
correct if necessary
(Y page 282).
X Cargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to
prevent the load from slipping.
X Place non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary. During loading
X Observe the gross axle weight rating and
permissible 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 maxi-
mum payload is thus reduced.
X Observe the notes on load distribution
(Y page

243).
The overall center of gravity of the load
should always be as low as possible, cen-
tered and between the axles near the rear
axle.
X Secure the load (Y page
244).
Observe the legal requirements of the coun-
try in which you are currently driving. Checks after loading
G
DANGER
Combustion engines emit poisonous
exhaust gases, such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the tailgate/rear-end door is open when
the engine is running, especially if the vehi-
cle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate/rear-end door. Never drive the
vehicle when the tailgate/rear-end door is
open.
X Securing 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.
X Doors/tailgate: close the sliding doors and
tailgate/door.
X Tire pressure: adjust the tire pressure
according to the vehicle load
(Y page 282).
X Driving 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
vehicle 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. Load distribution

Transporting loads Z

X
Always transport loads in the cargo com-
partment and with the seat backrests folded
up and properly locked in position.
X Always place the load against the backrests
of the front or rear seats.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the front or rear seats. Stow the load flush
with the rear or front seats.
X Always additionally secure the load with
suitable load-securing aids or tie downs.
Observe the following notes:
R Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of
the opposite seat belt. Cargo compartment variations
You can vary the cargo compartment accord-
ing to your transportation requirements as fol-
lows:
R by folding the seat backrests forward to the
table position.
R by removing the rear bench seat.
You will find information about rear bench
seats in the "Rear bench seats" section
( Y page
89). Securing loads
Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction,
braking maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the 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
maximum loading capacity of the weakest
cargo tie-down point into account.
If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to distrib-
ute the force absorption. Load the ancho-
rages evenly.
As the driver, you are responsible for ensuring
that: R The load is secured against slipping, tipping,
rolling or falling off in normal traffic condi-
tions, should the vehicle swerve to avoid an
obstacle, in the event of maximum full-stop
braking and on poor road surfaces
R The applicable requirements and guidelines
relating to load-securing practices are met
If this is not the case, this may constitute a
punishable offense, depending on local leg-
islation and any ensuing consequences.
Always observe the legal requirements for
the country you are currently in.
Make sure that the load is secure before every
journey and at regular intervals during a long
journey. Correct an incorrectly or inadequately
secured load if necessary.
Always observe the operating instructions or
the notes of the lashing strap manufacturer for
the operation of the lashing strap.
You can obtain information about securing the
load correctly from the manufacturer of the
load securing aids or tie down for securing the
load. Also observe the safety information in
the loading directions ( Y page 242).

WARNING
The cooling system is pressurized, particu-
larly when the motor is warm. If you open
the cap, you could be scalded if hot coolant
sprays out. There is a risk of injury.
Let the engine cool down before you open
the cap. Wear protective gloves and protec-
tive eyewear when opening. Open the cap
slowly to release pressure.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant tem-
perature must be below

coolant temperature gauge must no longer reach the first line after the letter
C on the
scale and/or the bar display.
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop. G
WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck. Thoroughly
clean the antifreeze from components
before starting the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork. Example: cap and coolant expansion tank

WARNING
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 down
and touch only the components described in
the following.
Brake fluid is hazardous to health. Also
observe the safety notes under "Service prod-
ucts and capacities"
(Y page 305). G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling 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
reservoir 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 cor-
rect the malfunction.
! Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately. Engine compartment

Maintenance and care Z

Maintenance
General notes
H
Environmental note
Observe measures to protect the environ-
ment when working on the vehicle. You
must observe the legal requirements when
disposing 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 environmen-
tally responsible manner. Comply with the
instructions 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 docu-
ments relating to maintenance measures and
repairs:
R relevant sections of the technical documen-
tation such as the Operator's Manual and
workshop information
R legal stipulations such as work safety regu-
lations and accident prevention regulations
While working under the vehicle, you must
secure the vehicle on jack stands with suffi-
cient 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
(Y page 32).
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 Opera-
tor'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
Warranty. You will find information about ser- vice products approved by Mercedes-Benz and
capacities under "Service products and capaci-
ties"

(Y page 305)
Maintenance services must be carried out in
accordance with the provisions and recom-
mendations in the Maintenance Booklet. Not
doing so could void the warranty claim and
lead to refusal of goodwill gestures after the
manufacturer has submitted a damage report.
Observe the information under "Mercedes-
Benz genuine parts" (Y page 34). 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.
i The service interval display does not pro-
vide information about the engine oil level.
The service interval display should therefore
not be confused with the engine oil level dis-
play.
For example, the display shows one of the fol-
lowing service messages for a few seconds: R Service A in .. days
R Service A Due or Service A Due
R Serv. 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
overdue service date is shown. The letter in
the display message indicates which service is
due. A stands for a minor service and B for a
major service.
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 mainte-
nance work, for example. Maintenance
