products to come into contact with your eyes
or open wounds. See a doctor immediately if
any service product is swallowed.
H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuel
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Before refuelling, turn off the engine and the
auxiliary heating *. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact with
your skin or inhaling fuel vapours is damaging
to your health.

Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Never mix
diesel with petrol. Even small amounts of
the wrong fuel result in damage to the
injection system. Damage resulting from
adding the wrong fuel is not covered by the
implied warranty.

Notes on fuel consumption
The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R when towing a trailer
R in mountainous terrain
i Only for certain countries: the respective
current consumption and emission values
of your vehicle can be found in the COC
papers (EC CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
The consumption figures for vehicles falling
under the EURO4 standard have been
determined in accordance with EU Direc-
tive 80 /1268 /EEC while figures for vehi-
cles falling under the EURO5 standard have
been determined in accordance with Reg-
ulation (EC) No. 715 / 2007, in each case
based on the currently applicable version.
The values do not refer to a specific vehicle.
Deviations from these values may occur
under normal operating conditions.
! Do not use any special additives, as they
can cause malfunctions and engine dam-
age. Damage resulting from the use of such
additives is not covered by the Mercedes-
Benz implied warranty. 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 or road conditions You can minimise your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly. AdBlue
®
i For BlueTEC vehicles only.
AdBlue ®
is a non-flammable, non-toxic, col-
ourless and odourless water-soluble fluid.
! Only use AdBlue ®
compliant with
ISO 22241. The use of special additives is
not permitted.
! Surfaces, such as carpets or paintwork,
which come into contact with AdBlue ®
while refilling should be rinsed immediately
with plenty of water. Immediately after
spilling, remove AdBlue ®
using a damp
cloth and cold water. If AdBlue ®
has
already crystallised, use a sponge and hot
water to clean it off. AdBlue ®
residues crys-
tallise after a certain period of time and soil
the affected surfaces.
High outside temperatures If AdBlue
®
is heated to above 50 † for an
extended period of time, e.g. due to direct
sunlight on the AdBlue ®
tank, AdBlue ®
may
start to decompose. Ammonia vapours may
develop as a result. G
Risk of injury
Ammonia vapours may escape if the
AdBlue ®
tank cap is opened at high tempera-
tures. Ammonia vapours have a pungent
odour and are particularly irritating to the
skin, to mucous membranes and to the eyes.
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale ammonia vapours. 288
