WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the
labels of the respective original containers.
Always store service products sealed in their
original containers. Always keep service
products out of the reach of children. G

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

Maintenance and care Z

Maintenance
General notes
H
Environmental note
Observe measures to protect the environ-
ment when working on the vehicle. You
must observe the legal requirements when
disposing of service products, e.g. engine
oil. This also includes all components, e.g.
filters, which have come into contact with
service products. Any qualified specialist
workshop can provide information about
this.
Dispose of empty containers, cleaning
cloths and care products in an environmen-
tally responsible manner. Comply with the
instructions for use of the care products.
Do not run the engine for longer than neces-
sary when the vehicle is stationary.
Before carrying out maintenance measures
and repairs, you must read the following docu-
ments relating to maintenance measures and
repairs:
R relevant sections of the technical documen-
tation such as the Operator's Manual and
workshop information
R legal stipulations such as work safety regu-
lations and accident prevention regulations
While working under the vehicle, you must
secure the vehicle on jack stands with suffi-
cient load capacity.
Never use a vehicle jack instead of stands. The
jack is designed only to raise the vehicle for a
short time when changing a wheel. It is not
suited for performing maintenance work under
the vehicle.
Please also refer to the notes about qualified
specialist workshops
(Y page 32).
The scope and regularity of the inspection and
maintenance work primarily depend on the
often diverse operating conditions. Specialist
knowledge beyond the scope of this Opera-
tor's Manual is required when carrying out
testing and maintenance work. This work
should only be carried out by trained staff.
The vehicle Maintenance Booklet describes
the scope and frequency of maintenance work
and contains additional notes on the Limited
Warranty. You will find information about ser- vice products approved by Mercedes-Benz and
capacities under "Service products and capaci-
ties"

(Y page 305)
Maintenance services must be carried out in
accordance with the provisions and recom-
mendations in the Maintenance Booklet. Not
doing so could void the warranty claim and
lead to refusal of goodwill gestures after the
manufacturer has submitted a damage report.
Observe the information under "Mercedes-
Benz genuine parts" (Y page 34). Service interval display
General notes The service interval display informs you of the
next service due date. Information on the type
of service and service intervals can be found in
the Maintenance Booklet.
i The service interval display does not pro-
vide information about the engine oil level.
The service interval display should therefore
not be confused with the engine oil level dis-
play.
For example, the display shows one of the fol-
lowing service messages for a few seconds: R Service A in .. days
R Service A Due or Service A Due
R Serv. A Exceed. by .. Days
Then either the remaining time or distance
until the next service due date is displayed. If
the service due date has been exceeded, the
elapsed time or distance traveled after the
overdue service date is shown. The letter in
the display message indicates which service is
due. A stands for a minor service and B for a
major service.
A qualified specialist workshop, e.g. an author-
ized Mercedes-Benz Commercial Van Center,
will reset the service interval display after the
service work has been carried out. You can
also obtain further information on mainte-
nance work, for example. Maintenance

Maintenance and care Z

Tire tread
The part of the tire that comes into contact
with the road.
Tire bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from com-
ing loose from the wheel rim.
SidewallThe part of the tire between the tread and the
tire bead.
Weight of optional extras The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg
(5 lbs). These
optional extras, such as high-performance
brakes, a roof rack or a high-performance bat-
tery, are not included in the curb weight and
the weight of the accessories.
TIN (Tire Identification Number) A unique identification number which can be
used by a tire manufacturer to identify tires,
for example for a product recall, and thus iden-
tify the purchasers. The TIN is composed of
the manufacturer identification code, tire size,
tire model code and manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
TWR (permissible trailer drawbar load)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of á in (1.6 mm)
has been reached. Distribution of the vehicle occupants
The distribution of vehicle occupants over des-
ignated seat positions in a vehicle.
Maximum permissible payload weightNominal load and goods/luggage load plus
68 kg (150 lbs) multiplied by the number of
seats in the vehicle. Changing wheels
Rotating the wheels
! On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting a wheel"
(Y page

298).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the tires according to the intervals
in the tire manufacturer's warranty book in
your vehicle documents. If no warranty book is
available, the tires should be rotated every
3,000 to 6,000 miles (5,000 to 10,000 km) or
earlier if tire wear requires. Do not change the
direction of rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Avoid oily or greasy cleaning
agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary. Direction of rotation
Tires with a specified direction of rotation have
additional benefits, e.g. if there is a risk of
hydroplaning. You will only gain these benefits
if the correct direction of rotation is observed. Changing wheels
