WARNING
Gases and fluids from substances that con-
stitute a health hazard or react aggressively
can escape even from securely closed con-
tainers. When transporting such substances
in the vehicle interior, your ability to concen-
trate or your health could be affected during
the journey. Malfunctions, short circuits or
electrical component system failures may
also result. There is a risk of an accident and
fire.
Do not store or transport any substances in
the vehicle interior which are hazardous to
health or react aggressively.
These instructions must also be observed for
vehicles where the cargo compartment is not fully separated from the driver's cab.
Partition with door/window: always keep thedoor/window in the partition closed during
transport.
Examples of substances that are hazardous
to health and/or react aggressively:
R Solvents
R Fuel
R Oil and grease

Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner. Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking.
R change gear in good time and use each gear
only up to 00C3of its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel consump-
tion. Environmental issues and recommen-

Service products and capacities
Important safety notes
G
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 Washer 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
Service products and capacitiesTechnical data

i
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

Information about oil consumption
!
If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func- tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distan-
ces, you should drive on a highway or on
rural roads for 20 minutes every 310 miles
(500 km). This ensures sufficient regener-
ation of the diesel particle filter.
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
(1000 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 250). Transmission and power steering oil
