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

tor lever
X
Thoroughly wipe with a damp cloth.
X Vehicles with leather upholstery: after
cleaning, use leather care agents that have
been recommended and approved by
Mercedes-Benz.
Cleaning the trim elements !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
X Wipe the trim elements with a damp, lint-
free cloth, e.g. a microfiber cloth.
X Heavy soiling: use care products and
cleaning agents recommended and
approved by Mercedes-Benz.
Cleaning the seat covers !
Do not use microfiber cloths to clean gen-
uine leather or artificial leather covers. If
used often, a microfiber cloth can damage
the cover.
! Clean:
R artificial leather covers with a cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid.
R cloth covers with a microfiber cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid. Wipe entire
seat sections carefully to avoid leaving
visible lines. Leave the seat to dry after-
wards. Cleaning results depend on the
type of dirt and how long it has been
there.
R genuine leather covers carefully with a
damp cloth, then wipe the covers down
with a dry cloth. Make sure that the
leather does not become soaked. Other-
wise, the leather could become rough or
cracked. Only use leather care agents
that have been tested and approved by
Mercedes-Benz. You can obtain these
from a qualified specialist workshop.
i Please keep in mind that:
R leather covers are a natural product and,
as such, are subject to a natural aging process. Leather may react differently,
e.g. increased wrinkling, to certain envi-
ronmental influences (such as high
humidity or intense heat).
R regular care is essential to make sure that
the appearance and comfort of the covers
are retained over time.
To clean genuine leather covers: X Remove any dust, crumbs etc. If necessary,
carefully vacuum-clean the seat covers.
X Carefully wipe the leather seat covers with a
damp cloth.
X Wipe over again with a dry cloth.
Make sure that the leather does not become
soaked, especially perforated parts.
X Then treat the leather seats with a leather
care foam.
Only use leather care agents that have been
tested and approved by Mercedes-Benz.
Observe the manufacturer's instructions.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident. This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above
176 ‡
(80 †) or in direct sunlight.
Remove any stains or dirt immediately. This
will avoid residue or damage. X Use clean, lukewarm water and soap solu-
tion.
Cleaning the headliner and carpets X
Headliner: if it is very dirty, use a soft brush
or dry shampoo.
X Carpets: use the carpet and textile cleaning
agents recommended and approved by
Mercedes-Benz. Care

Maintenance and care Z

The following components of the different
vehicle versions influence fuel consumption:
R tire sizes, tire tread, tire pressure, tire condi-
tion
R transmission ratios for the drive assemblies
R additional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the
consumption figures determined according to
EU Directive
80/1268/EEC.
Details on fuel consumption can be called up
in the on-board computer:

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

Capacities
!
Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off.
Oil change including oil filter Engine oil
Approx. 2 US gal
(7.75 l )Additives
!
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
( Y page 252). Service products and capacities
