Important safety notes
G
WARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be
thrown about, striking vehicle occupants.
This also applies to:
R luggage or loads
R seats 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 vehi-
cle. G
WARNING
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
characteristics. There is a risk of an acci-
dent. Always make sure that the center of gravity
of the load is:
R between the axles
and
R as low as possible, near the rear axle. G
WARNING
When the permissible wheel loads, axle
loads and/or the maximum permissible
gross vehicle weight are exceeded, driving
safety is compromised. The handling as well
as steering and braking characteristics may
be significantly impaired. Overloaded tires
may overheat, 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 car-
rier load.
R Do not stack luggage or loads higher than
the backrests.
R Objects to be transported should preferably
be stowed in the cargo compartment.
R When transporting luggage, always use the
cargo tie-down rings for securing loads and
a cargo net, if installed.
R Use 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
discard criteria contained therein.
Load securing aids or tie downs must not be
used if:
R identification marks are missing or illegible
R there are yarn breakages, damage to bear-
ing seams or other signs of tearing
R there are signs of shearing, deformation,
pinching or other damage
R there is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be 242
Loading guidelines
Transporting loads

The prescribed service interval is based on
normal vehicle use. Service work will need to
be performed more frequently than prescribed
if the vehicle is operated under more arduous
conditions or with higher loads. Such arduous
conditions include:
R regular city driving with frequent intermedi-
ate stops
R driving predominantly short distances
R frequent operation in mountainous terrain or
on poor road surfaces
R leaving 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 exam-
ple, replaced more frequently. Under more
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist work-
shop, e.g. an authorized Mercedes-Benz Com-
mercial Van Center.

Important safety notes
Work on the battery, e.g. removing or instal-
ling, requires specialist knowledge and the use
of special tools. Therefore, always have work
on the battery carried out at a qualified spe-
cialist workshop. G
WARNING
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
system, the ABS (anti-lock braking system)
or the ESP ®
(Electronic Stability Program).
The operating safety of your vehicle may be
restricted.
You could lose control of the vehicle, for
example:
R when braking
R in 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
incident, contact a qualified specialist work-
shop immediately. Do not drive any further.
You should have all work involving the bat-
tery carried out at a qualified specialist
workshop.
Further information can be found under "ABS"
(Y page
67) and under "ESP ®
" (Y page 68). G
WARNING
Electrostatic build-up can lead to the crea-
tion of sparks, which could ignite the highly
explosive gases of a battery. There is a risk
of an explosion.
Before handling the battery, touch the vehi-
cle 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. 258

Maintenance and care

X
Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet grilles.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agents dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Under no circumstances use power wash-
ers in the vehicle interior. The pressurized
water and associated spray produced by the
power washer could cause extensive dam-
age to the vehicle.
! When using high-pressure cleaning equip-
ment, maintain a minimum distance of
approx. 1 ft (30 cm
) between the spray noz-
zle and the vehicle parts. Do not use a
power washer with a round-jet nozzle. You
could damage the vehicle or engine parts.
! Keep the water jet moving constantly
while cleaning. This will avoid causing dam-
age to the vehicle.
Do not point the water jet at:
R door joints
R rear view camera
R air bellows
R brake hoses
R wheel balance weights
R electrical components
R electrical connections R
seals
R drive train, especially not at the inter-
mediate bearing of the propeller shaft
Cleaning the engine !
Water must not enter intake or ventilation
openings. When cleaning with high pressure
water or steam cleaners, the spray must not
be aimed directly at electrical components
or the terminals of electrical lines.
Preserve the engine after the engine has
been cleaned. Protect the belt drive system
from exposure to the preservative agent.
Also observe the information under "Power
washers"

(Y page 265).
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Cleaning the windows G
WARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury. Care

Maintenance and care
Z

Always switch off the windshield wipers and
the ignition before cleaning the windshield
or wiper blades.
! Do not fold the windshield wipers away
from the windshield unless the hood is
closed. Otherwise, you could damage the
hood.
! Hold the wiper arm securely when folding
back. The windshield could be damaged if
the wiper arm smacks against it suddenly.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring.
There is otherwise a risk of damaging the
windows.
! Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstances
prevent water from draining away. This can
lead to corrosion damage and damage to
electronic components.
X Clean the inside and outside of the windows
with a damp cloth and a cleaning agent that
is recommended and approved by
Mercedes-Benz. Exterior
Cleaning the wheels !
Do not use any acidic or alkaline cleaning
agents. They can cause corrosion on the
wheel bolts or the retainer springs for the
wheel-balancing weights.
! Do not park your vehicle for a long period
of time directly after cleaning, particularly
after cleaning the wheel rim with wheel
cleaner. Wheel cleaner can lead to the
increased corrosion of the brake discs and
pads. Therefore, drive for a few minutes
after cleaning. By heating up the brakes, the
brake discs and pads dry. The vehicle can
then be parked for a long period of time.
If you clean the wheels with a power washer,
observe the safety notes for the power washer (Y page 265). You could otherwise damage
the tires.
Cleaning the wiper blades G
WARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield
or wiper blades.
! Do not fold the windshield wipers away
from the windshield unless the hood is
closed. Otherwise, you could damage the
hood.
! Do not pull the wiper blade. Otherwise, the
wiper blade could be damaged.
! Do not clean wiper blades too often and
do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
! Hold the wiper arm securely when folding
back. The windshield could be damaged if
the wiper arm smacks against it suddenly.

Modifications to the brake system or wheels
are not permitted. The use of spacers or brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
Further information on wheels and tires can be
obtained at any qualified specialist workshop. Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
( Y page

282).
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your speed
immediately. Stop the vehicle as soon as pos-
sible to check the wheels and tires for dam-
age. Hidden tire damage could also be causing
the unusual handling characteristics. If you
find no signs of damage, have the tires and
wheels checked at a qualified specialist work-
shop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged. 278
Operation
Wheels and tires

Regular wheel and tire checks
G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two
weeks, as well as after driving off-road or on
rough roads. Damaged wheels can cause a
loss of tire pressure. Pay particular attention
to damage such as:
R cuts in the tires
R punctures
R tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tire tread across the whole
width of all the tires
(Y page 279). If neces-
sary, turn the front wheels to full lock in order
to inspect the inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than the
standard valve cap or other valve caps
approved for your vehicle by dealers listed on
the inside of the front cover. Do not install any
other valve caps or systems, e.g. tire pressure
monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if necessary (Y page 282).
The service life of tires depends on various
factors, including the following:
R Driving style
R Tire pressure
R Mileage Tire tread
G
WARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer
able to dissipate water. This increases the risk of hydroplaning when the road surface
is wet, particularly when the vehicle's speed
is not adapted to the road conditions. There
is a risk of an accident.
When the tire pressure is too high or too
low, tires may wear differently at different
points on the tire tread. Therefore, regularly
check the tire tread depth and the condition
of the tread across the whole width of all
tires.
Minimum tire tread depth on:
R Summer tires: â in (3 mm

)
R M+S tires: ã in (4 mm)
For safety reasons, have the tires replaced
before they reach the legally prescribed min-
imum tire tread depth. Marker : shows the location where the bar
indicator (arrow) for tread wear is integrated
into the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tire tread
depth is approximately á in (1.6 mm

). If this
is the case, the tire is so worn that it must be
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only use wheels with tire sizes approved by
Mercedes-Benz.
R Only mount tires of the correct size onto the
wheels. Operation
