tnot possible message appears in
th em ultifunction display and the engine does
not start ,you must top up with at least 3. 8l
of AdBlue ®
(approximately 2AdBlue ®
refill
bottles).
i If you driv ethe vehicle faster than
15 km /h,the Refill AdBlue Se eOwn‐ er's Manual message goes ou
tafter
approximately one minute.
If th eoutside temperature is lower than
Ò11 †, it may be difficult to top up. If
AdBlue ®
is frozen and there is an activ ewarn-

!
In order to fil lthe AdBlue ®
tank, the vehi-
cle must be parked on alevel surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on alevel surface.
Fluctuations in capacity will thus be avoi-
ded. Filling avehicle standing on an uneven
surface is not permitted. There is adanger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatmen tcom-
ponen ts.
! Surfaces which have come into contact
with AdBlue ®
while refilling shoul dbe
rinsed immediately wit hwater, or remove
AdBlue ®
with amoist clot hand cold water.
If AdBlue ®
has alread ycrystallised, us ea
sponge and cold water to clean the area.
AdBlue ®
residue crystallises after acertain
amount of tim eand soils the affected sur-
faces.
! AdBlue ®
is not afuel additive and must
not be added to the fuel tank .IfAdBlue ®
is
added to the fuel tank ,this can lead to
engin edamage.
Have the AdBlue ®
tank refilled at aqualified
specialist workshop. However ,you can also
top up the AdBlue ®
tan k:
R at afilling station with an AdBlue ®
filling
pump
R with AdBlue ®

WARNING
If you shift down on aslippery road surfac ein
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible ,poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
aw indow on the side of the vehicle that is not
facin ginto the wind.
! Take care not to damage the sealing strip
and the mould ingont he side of the rear
window when scrapin gice off the rear win-
dow. Driving tips

Fuel consumption informa tion H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effec t).Y our
vehicle' sCO
2emissions are directly related to
fuel consumption and therefore depend on:
R efficien tuse 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 carefull yand having it serv-
iced regularly.
The vehicle will use more fuel than usua lin
the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing atrailer
i Only for certain countries :you can find
the curren tconsumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
documents ar edelivered with your vehicle.
The consumption figures were in each case
based on the curren tlya pplicable version:
R for vehicles that comply with standards
up to and including the EURO 4standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles tha tcompl ywith or exceed
the EUR O5standard ,inaccordanc ewith
Regulatio n(EC )N o. 715/2007
