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.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 318).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
rubber. If paint, plastic or rubber has come into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years at
a qualified specialist workshop. Observe the
information on brake fluid in the "Technical
data" section (Y page 324). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immedi-
ately 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. 254

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. H
Environmental note
Dispose of service products in an environ-
mentally responsible manner.
Service products include the following:
R Fuels, e.g. diesel
R Additives for the exhaust gas aftertreat-
ment, e.g. Diesel Exhaust Fluid (DEF)
R Lubricants, e.g. engine oil, transmission oil
R Coolant
R Brake fluid

R Climate control system refrigerants
Approved service products comply with the
highest quality standards and are listed in the MB Specifications for Service Products. Only
use service products approved for the vehi-
cle. This is an important condition for the war-
ranty.
You will recognize the approved service prod- ucts by the inscription on the container: MB
Approval (e.g. MB Approval 228.5)
Other identifications and recommendations
refer to quality level or a specification accord-
ing to an MB Sheet Number (e.g. MB 228.5).
They are therefore not necessarily approved.
Further information can be obtained at any
qualified specialist workshop.
Additives for approved service products are
neither required nor permitted. Approved fuel additives are the exception. Additives can cause engine damage and must therefore not
be added to the service products.
The use of additives is always the responsi-
bility of the vehicle operator. The use of addi- tives may result in the restriction or loss of
your Limited Warranty entitlements. Fuel
Important safety notes G
WARNING
Fuel is highly flammable. Improper handling of fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creatingsparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating before refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
When handling, storing and disposing of fuels,
please observe the relevant regulations. 318

Malfunctions resulting from paraffin sep-
aration can only be rectified by heating the
entire fuel system. Park the vehicle in a
heated garage, for example.
To prevent operating problems, diesel with
better flow qualities is available during the
winter months. You can obtain information at the gas station or from your fuel supplier.
Your vehicle is equipped with a fuel preheat-
ing system. This improves the flow properties
of the diesel by approximately 46 ‡ (8 †).
ULTRA-LOW SULFUR DIESEL can be used
without risk of malfunction down to an out-
side temperature of approximately 14 ‡
(00F810 †).
Fuel additives
! Do not add gasoline or kerosene to diesel
fuel to improve its flow characteristics.
Gasoline or kerosene impairs the lubricat-
ing properties of the diesel fuel. This can
result in damage to the fuel injection sys-
tem, for example.
Information on fuel consumption H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
Fuel consumption depends on: R the vehicle version
R the style of driving R
the operating conditions
R the type or quality of the fuel 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
To keep fuel consumption low, observe the
advice in the "Protection of the environment" section (Y page 23).
The following components of the different
vehicle versions influence fuel consumption:
R tire sizes, tire tread, tire pressure, tire con-
dition
R body
R transmission ratios for the drive assem-
blies
R additional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption
figures for your vehicle may deviate from the
consumption figures determined according
to EU Directive 80/1268/EEC.
Data concerning fuel consumption are recor- ded in the on-board computer; use the steer-
ing wheel buttons to call up the Trip com-
puter menu (Y page 195).
Diesel Exhaust Fluid (DEF) General notes
! Only use DEF in accordance with
ISO 22241. The exhaust gas aftertreatment system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other reduc-
ing agents will invalidate the New Vehicle
Limited Warranty. 320
Service products and capacitiesTechnical data
!
If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF heats up, e.g. in direct sunlight, in the
DEF supply reservoir for some time to over
122 ‡ (50 †), ammonia vapor will develop.
Low ambient temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(00F811 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed at temperatures under 12 ‡ (00F811 †).
Additives and tap water
! Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi- tives or tap water will invalidate the New
Vehicle Limited Warranty.
Storage
! Containers made of aluminum, copper,
copper alloys as well as unalloyed or
galvanized steel are not suitable for storing
DEF. If stored in these types of containers, DEF could cause constituents of these met- als to dissolve and cause irreparable dam-
age to the exhaust gas aftertreatment.
Damage caused by such impurities in the
DEF will invalidate the New Vehicle Limited
Warranty. Only store DEF in containers made of high-
alloy Cr‑Ni steel or Mo‑Cr‑Ni steel in accord-
ance with DIN EN 10 088 ‑1/2/3 or plastic
containers made of polypropylene or poly-
ethylene.
Purity
! Impurities in DEF (e.g. caused by other
service products, cleaning agents, dust,
etc.) result in increased emissions, mal-
functions, catalytic converter damage or
engine damage.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g.
during repair work, the same liquid must not
be used to refill the tank. Its purity is no longer guaranteed.
Disposal
Observe country-specific laws and regula-
tions when disposing of DEF.
003D Environmental note
Dispose of DEF in an environmentally respon- sible manner.

For vehicles with a 4-cylinder, in-line
engine (OM 651), the DEF consumption of
the vehicle is:
R as a Cargo Van/Passenger Van, approx.
2322 MPG (0.2 l/100 km)
R as a Cab Chassis, approx. 1720 MPG
(0.35 l/100 km)

For vehicles with a 6-cylinder, in-line
engine (OM 642), the DEF consumption of
the vehicle is:
R as a Cargo Van/Passenger Van, approx.
2322 MPG (0.10 l/100 km)
R as a Cab Chassis approx. 1720 MPG
(0.14 l/100 km)
In each case, the stated consumption figure is a mean value between urban and extra-urban
driving cycles. The consumption figure does
not refer to a specific vehicle, but is provided for the purposes of comparison between dif-
ferent vehicle types.
DEF consumption, like fuel consumption, is
very dependent on the driving style and the
operating conditions. This means that the real
consumption figures during operation of your
vehicle may deviate from those stated. Engine oil
General notes !
The bottles of the various engine oil types
are marked with ACEA (Association des
Constructeurs Européens d'Automobiles)
and/or API (American Petroleum Institute) classifications. Only use approved engine
oils that conform to the following MB Spec-
ifications for Service Products and the pre- scribed ACEA and/or API classifications.
Using engine oils of another quality is not
permitted and may invalidate the New Vehi-
cle Limited Warranty.
The use of other, non-approved engine oils
for diesel engines can cause damage to the
diesel particle filter (DPF).
Use only engine oils that have been approved for your vehicle according to the MB Specifi-
cations for Service Products. The MB Specifications for Service Products
are valid for your vehicle 13
R 228.51
R 229.31
R 229.51
These are high quality engine oils which have
a positive effect on:
R engine wear
R fuel consumption
R exhaust gas emissions
Multi-grade engine oils of the prescribed SAE class (viscosity) may be used all year round,
taking the outside temperatures into
account.
Engine oil viscosity !
If the SAE viscosity class of the engine oil
used does not cover the outside tempera-
ture range in which you are operating the
vehicle, it must be changed in good time, in
particular before the cold season commen- ces. Using an engine oil that does not have adequate 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 signifi-
cantly due to aging in use, especially at low outside temperatures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.
13 If the quality grade is not available for diesel, you may also add engine oils meeting the requirements in MB
Sheet No. 228.5, 229.3 or 229.5. The quantity to be added is then limited to a maximum of 1 qt (1 l). 322
Service products and capacitiesTechnical data
must be used in the system all year round to
ensure anti-corrosion protection and a raised
boiling point – even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys- tem, use only approved corrosion inhibitor/
antifreeze that comply with the Mercedes-
Benz Specifications for Service Products.
We recommend corrosion inhibitor/anti-
freeze that meets the requirements in MB
Specifications for Service Products Sheet
Number 325.
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 cool-
ing 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.
If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion inhibi-
tor/antifreeze additive. The water used as
part of the coolant mixture must fulfill certain requirements; these are usually fulfilled by
drinking water. If the water quality is not suf-ficient, you must treat the water.
