General notes When handling engine oil, observe the impor-
tant safety notes on operating fluids
(Y page

305).
The quality of the engine oil used is of decisive
importance for the engine's functionality and
operating life. Mercedes-Benz continually
approves engine oils based on complex experi-
ments according to the current state of the
art.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines. Mercedes-Benz recommends having
the oil changed at a qualified specialist work-
shop. Information about engine oils approved by
Mercedes-Benz can be obtained:
R from any Mercedes-Benz Commercial Van
Center
R on the Internet at
http://bevo.mercedes-benz.com

by enter-
ing the designation, e.g. 229.5.
Mercedes-Benz approval is indicated on the oil
container by the inscription „MB-Freigabe“ or
„MB Approval“ and the corresponding designa-
tion, e.g. MB-Freigabe or MB Approval 229.5.
Designations of the approved engine oils for
your vehicle MB-Freigabe or MB
Approval
229.5,
229.62 Mercedes-Benz recommends that you only use
approved multigrade engine oils of the SAE
classes

SAE 0W-30 and SAE 0W-40 or
SAE 5W-30 and SAE 5W-40. These engine oils
ensure optimum lubrication even at very low
outside temperatures (Y page 309).
To achieve the lowest possible fuel consump-
tion, it is recommended to use the engine oil
specifications marked in the table for the low-
est SAE viscosity class. Observe possible
restrictions of the released SAE classifications.
When refilling, we recommend that you only
use engine oil of the same grade (MB-Freigabe
or MB Approvaldesignation) and SAE class as
the oil filled at the last oil change.
i If the engine oils listed in the table are not
available, you may add the following engine
oils until the next oil change:
R MB-Freigabe or MB Approval 229.1, or
ACEA A3
This must only be added once and the
amount must not be greater than 1 qt
(1.0 l).
Subsequently have the engine oil changed
at the earliest possible opportunity.
! Using engine oils of another grade quality
is not permitted.
2 Recommended for the lowest possible fuel consumption (lowest viscosity class in each case taking into
account possible restrictions of the approved SAE classifications). 308

!
Do not use any additives in the engine oil.
This could damage the engine.
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

Brake fluid
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.

Important safety notes 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.
When handling, storing and disposing of cool-
ant and antifreeze, please observe the relevant
regulations and the important safety notes for
operating fluids

(Y page 305).
Coolant additive with corrosion and
antifreeze protection !

the coolant system and reduce the engine's
service life.
The coolant is a mixture of water and anti-
freeze and corrosion inhibitor. It performs the
following tasks:
R Anti-corrosion protection
R Antifreeze protection
R Raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze/corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure anti-corrosion protection and
a higher boiling point, even in countries with
high outside temperatures.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least
50%. This way, the engine cooling
system is protected against freezing down
to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not
be dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the require-
ments in the Mercedes-Benz Specifications for
Service Products Sheet Number 325.

WARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
! Only use washer fluid which is suitable for
lamp lenses, e.g. MB SummerFit or MB Win-
terFit. Unsuitable washer fluid may damage
the lamp lenses of the headlamps.
When handling washer fluid, observe the
important safety notes on service products
(Y page

Mixing ratio Add windshield washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the ambient temperature. At temperatures above freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Summerwash to prevent
smearing.
At temperatures below freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Winterwash if there is a dan-
ger of frost.
This prevents washer fluid from freezing on
the windshield.
