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.

(Y page 287).
Important safety notes G
WARNING
Risk of accident due to incorrect tire
pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle placard or
the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han-
dling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver's responsibility to maintain cor-
rect tire pressure, even if under-inflation has
not reached the level to trigger illumination
of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale
will flash for approximately one minute and
then remain continuously illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illumina-
ted, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the
vehicle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels
on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the
TPMS to continue to function properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating conditions
(Y page
282).
Note that the correct tire pressure for the cur-
rent operating conditions must first be pro-
gramed into the tire pressure monitor. If a sub-
stantial pressure loss occurs, the warning
threshold for the warning message is aligned
to the taught-in reference values. Restart the
tire pressure monitor after adjusting the cold
tire pressure ( Y page 288). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tire pressure drops significantly.
The tire pressure monitor does not warn you if
a tire pressure is incorrect. Observe the notes
on the recommended tire pressure
(Y page 282).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. following
penetration by a foreign object. In this event,
brake the vehicle until it comes to a standstill.
Avoid sudden steering movements.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
R if the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig- 286

Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel
system due to contaminated fuel.
i E10 fuel contains an admixture of up to
10% bioethanol. Your vehicle is E10 compat-
ible. You can refuel your vehicle with E10
fuel.
i You can obtain information on fuel grades
at a qualified specialist workshop or at a gas
station. If there is no identification on the
filling pump, consult a gas station attendant.
For more information about refueling
(Y page

Fuel additives
! Operating the engine with subsequently
added fuel additives can cause engine dam-
age. Do not mix fuel additives with fuel. This
does not include additives for the removal
and prevention of deposits. Gasoline can
only be mixed with additives recommended
by Mercedes-Benz. Follow the instructions
in the product description. You can find fur-
ther information on recommended additives
in any Mercedes-Benz Commercial Van Cen-
ter.
Mercedes-Benz recommends using brand-
name fuels with additives.
If you use fuels without these additives for a
long period of time, deposits can form. This
primarily forms on the inlet valve and in the
combustion chamber.
In some countries, the available fuel grade
may be inadequate. Residue could build up in
the fuel injection system as a result. In this
case, in consultation with a Mercedes-Benz
Commercial Van Center, the fuel should be
mixed with the cleaning additive recommen-
ded by Mercedes-Benz. You must observe the
notes and mixing ratios indicated on the con-
tainer.
Do not add other fuel additives to the fuel.
This results in unnecessary costs and can
damage the engine. Information on fuel consumption H
Environmental note
CO 2 (carbon dioxide) is the gas that accord-
ing to the current state of knowledge is
mainly responsible for the heating of the
earth's atmosphere (greenhouse effect). The
CO 2 emissions of your vehicle vary in direct
correspondence with the fuel consumption
and is therefore dependent on:
R the efficient utilization of the fuel by the
engine
R the respective style of driving
R other non-technical factors, such as envi-
ronmental influences, condition of the
road or traffic flow, for example
You can help to minimize CO 2 emissions
with a conservative driving style and regular
maintenance of your vehicle .
Only for certain countries: the respective cur-
rent consumption and emission values of your
vehicle can be found in the COC papers (EC
CERTIFICATE OF CONFORMITY). These docu-
ments are supplied when the vehicle is deliv-
ered.
Consumption figures were found in the cur-
rently valid respective version: R for vehicles with exhaust gas standard Euro
6 as per directive (EC) no. 715/2007
R for vehicles with exhaust gas standard
EURO VI as per directive (EC) no. 595/2009
Fuel consumption depends on:
R the vehicle version
R the style of driving
R the operating conditions
R the fuel type and fuel grade used
The vehicle will use more fuel than usual in the
following situations:
R at very low outside temperatures
R in city traffic
R during short journeys
R on mountainous terrain
R when towing a trailer

Engine oil viscosity !
If the SAE class of the engine oil used does
not cover the outside temperature range in
which your vehicle is traveling, you must
change the engine oil in good time, in partic-
ular before the cold season commences.
Using an engine oil that does not have ade-
quate temperature characteristics can lead
to engine damage.
The temperature range information of the
SAE classification always refers to that of
fresh oil. The temperature characteristics of
the engine oil may deteriorate significantly
as a result of aging during vehicle operation,
especially at low outside temperatures.
Therefore, have the engine oil changed
before the cold season commences. Use an
approved engine oil of the specified SAE
class. Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means
that it is thin. Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The viscosity class of
the engine oil can have an influence on the
fuel consumption. The table displays the SAE
classification to be used. The low temperature
characteristics of engine oils can noticeably
deteriorate during operation, e.g. from aging,
soot and fuel accretion. For this reason, regu-
lar oil changes using an approved engine oil
from the suitable SAE classification are
urgently recommended.
Oil change Oil change intervals depend on the vehicle's
operating conditions and the quality of the
engine oil used. The on-board computer auto-
matically shows the date for the next oil
change as an event message in the display.
Mercedes-Benz recommends having the oil
changed at a qualified specialist workshop.
Information about oil consumption Depending on the driving style, the vehicle
consumes a maximum of 1.0 US qt

(1.0 l) of
engine oil over a distance of 620 miles
(1,000 km).
Oil consumption may be higher if:
R The vehicle is new.
R You mainly operate the vehicle under ardu-
ous operating conditions.
R You frequently drive at high engine speeds.
Regular maintenance is one of the precondi-
tions for moderate rates of consumption.
You can only estimate the oil consumption
after you have driven a considerable distance.
Check the engine oil level on a regular basis,
e.g. weekly or each time you refuel

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.
! Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations and the important safety notes for service
products (Y page
305).
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified
intervals by a qualified specialist workshop.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due.
Use only approved brake fluids that comply
with the Mercedes-Benz Specifications for Ser-
vice Products. Always check for the identifica-
tion DOT 4 plus.
