reasons concerning th
eoperating permit.
This also applie sincountries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics wil lbedifferen tincomparison
to when drivin gwithout atrailer and it will
consume more fuel.
On long and stee pdownhil lgradients ,you
must select shift range 1,2or 3in good time.
i This also applies if you have activated
cruise con trol, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to prevent the
vehicle from gainin gspeed. This relieves the
load on the brak esystem and prevent sthe
brakes from overheating and wearing too
quickly .Ifyou need additional braking,
depress the brake pedal repeatedly rather
than con tinuously.
Driving tips If the trailer swings from sid
etoside:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain agreater distance from th evehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea
level. Whe ndriving in mountainou sareas,
note that th epower outpu tofthe engine,
and consequen tlyt he vehicle' sgradient-
climbing capability ,decrease with increas-
ing altitude. Folding out the ball coupling
G
WARNING
If the ball coupling is not correctly engaged,
the trailer can detach. There is arisk of an
accident.
Always engage the ball coupling as described. G
WARNING
If you release the ball coupling or it does not
engage correctly when folding in, it will swing
out. Within pivoting range of the ball coupling,
there is an increased risk of an accident and
injury.
Only release the ball coupling if the pivoting
range is unobstruc ted. Alway smake sure that
the ball coupling engages when folding in.
! AMG vehicles and vehicles with AMG
bodystyling: remove the cover below the
bumper before you fold out the ball cou-
pling. Otherwise, the ball coupling, the
cover and the bumper could be damaged.
Before you can tow atrailer with your vehicle,
yo um ust fold out the ball coupling.
X Make sure that the vehicle is stationary. X
AMG vehicles and vehicles with AMG
bodystyling: pull down cover :by han-
dle ;in the direction of the arrow until it

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
Deviation sfrom thes evalues may occur
under normal operating conditions. AdBlue
®
Important safety notes AdBlue
®
is aw ater-soluble fluid for the
exhaust gas aftertreatmen tofdiesel engines.
It is:
R not poisonous
R colourless and odourless
R not flam mable
When you open the AdBlue ®
container, small
amou ntsofa mmonia vapou rmay be
released.
Ammonia vapours have apungen todour and
are particularly irritatin gtothe skin ,to
mucous membranes and to th eeyes. You may
experie nceab urnin gsensation in your eyes,
nose and throat. Coughing and waterin gof
the eyes are possible.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at atemperatur eofapprox-
imately -11 †. The vehicle is equipped with
an AdBlue ®
preheati ngsyste matt he factory.
Winter operation can therefor ebeguaran-
teed even at temperatures below -11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g. due to other
servic eproducts, cleaning agents or dust)
lead to:
R increased emissio nvalues
R damage to the catalytic converter Service product
