driver'sweight of approximately 150 lbs (68 kg).
The permissible Gross Combination Weight Rat-
ing is vehicle-specific and depends on the equip-
ment level.
When driving with atrailer, you should not
exceed the permitted Gross Combination
Weight Rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle docu-
ment sand on the trailer tow hitc htype plates for
the trailer and the vehicle (
Ypage 294). The
basic values approved by the manufacturer can
also be found in the "Technical data" section
(
Ypage 305). If the values vary, the lowest
value always applies.
Loading atrailer
!Utiliz ethe maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permissible
noseweight ,otherwise the trailer may come
loose.
RThe load must be distributed over the vehicle
and the trailer so as not to exceed either the
maximum permissible values for the gross
vehicle weight ratin g(GVWR) and gross trailer
weight (GTW), the gross combination weight
ratin g(GCWR), nor the maximum permissible
gross axle weight ratin g(GAWR) and trailer
drawbar noseweight ratin gofyour vehicle.
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the rear axle load. This will pre-
vent you from exceeding the permissible
gross axle weight (GAWR).
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight ratin g(GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-
missible values. Have the vehicle/trailer com-
bination weighed on acalibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle includin gthe driver,
passenger sand load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight ratin gofthe fronta nd rear axles
(GAWR), the gross trailer weight (GTW), the gross combination weight ratin
g(GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrectw iring of the connector plug could,
under certain circumstances, cause malfunc-
tion sint he vehicle's other electronic sys-
tems .Wet herefore recommend having the
connector plug wired at aqualified specialist
workshop.
!You can connec taccessories with amaxi-
mum power consumption of 240 Wtothe
permanen tpower supply.
You must not charge atrailer battery using the
power supply.
Your vehicle may be equipped with various elec-
trical installations for trailer towing .Depending
on your trailer, you may need an adapter to con-
nec tthe electrical system of the trailer with that
of the vehicle.
The trailer socket of your vehicle is equipped at
the factory with apermanen tpower supply.
The permanen tpower supply is on the trailer
socket pin assignmen t4.
Note that the permanen tpower supply of the
trailer is not switched off when the on-board
voltage is low. This can completely discharge
the starter battery of your vehicle.
Further information on the electrical equipment currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.

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 arduousc on-
ditions or with higher loads. Such arduousc on-
ditions include:
Rregularc ity driving with frequent intermediate
stops
Rdriving predominantly short distances
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

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 aqualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort 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 arisk of an accident.
In the event of ashort circuit or asimilari nci-
dent, contact aqualified specialist workshop

(
Ypage 62) and under "ESP®"(Ypage 64).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignit ethe highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handlin gthe battery, touc hthe vehicle
body to remove any existin gelectrostatic
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-
ter ya re electro statically charged. Electrostatic
charging results, for example, from:
Rwearings ynthetic clothing
Rfriction betwee nclothing and the seat
Rdraggingorp ushingthe battery across carpet
flooring or any other synthetic materials
Rrubbingt he battery with cloths or towels.
Comply with the followings afetyprecautions
and tak eprotective measuresw hen handling
batteries.
Risk of explosion.E xplosive oxyhy-
drogen is produced when batteries
are being charged. Only charge bat-
teries in well-ventilated areas.
Fire ,open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Batter yacid is caustic. Avoid con-
tac twith the skin ,eyes or clothing.
Wear acid-proof protective gloves.I f
skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and the nclean the affec-
ted areas with water .Consult adoc-
tor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can splash
int oy our eyes. Rinse acid splashes
to the eyes immediately with clean water and contac
tadoctor immedi-
ately.
Keep children at asafe distance.
Children are not able to assess the
danger sposed by batteries and
acid.
When handlin gbatteries, observe
the safetyp recautionsand special
protective measuresc ontained in
this Operator's Manual.
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of the mwith
the household rubbish. They
must be collected separately and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to aqualified spe-
cialist workshop or aspecial
collection point for used bat-
teries.
Observe the followingn otes:
RRecharge the battery more frequently, if you:
-predominantly drive shortd istances
-predominantly drive at low outside temper-
atures
-leave the vehicle parked for alengthy
period
In order for the batteries to achiev etheir max-
imum possible service life, the ymust always
be sufficiently charged.
RConsult an authorized Mercedes-Ben zCom-
mercial Van Center if you wish to leave your
vehicle parked for along period of time.
RWhen you park the vehicle, remove the Smart-
Key if you do not require any electrical con-
sumers. The vehicle will the nuse very little
energy, thus conserving battery power.
RIf your vehicle requiresj ump-starting, or if you
wish to provide jump-startin gassistanc eto
