Genera lnotes To function properly, BlueTE
Cexhaust gas after-
treatment must be operated with the reducing
agent AdBlue ®
.
When the supply of AdBlue ®
is almost used up,
the Refill AdBlue See Owner's Manual Refill AdBlue See Owner's Manual
message is shown in the multifunction display .A
warning tonea lso sounds.
If the Refill AdBlue No start in Xkm
Refill AdBlue No start in Xkm
message is shown in the multifunction display,
you can still drive the vehicle over the distance
shown. If AdBlue ®
is not topped up, you will
subsequently be unable to startt he engine.
When you see the warning message, it is rec-
ommended that you fill the AdBlue ®
reservoir
with 10 litres of AdBlue ®
.T his ensures that the
AdBlue ®
supply will last until the next regular
service due date.
Further information about BlueTEC exhaust gas

can
be obtained from any Mercedes-Benz Service
Centre.
i You can also have the AdBlue ®
tank refilled
at aq ualified specialist workshop.
If the outside temperature is lower than Ò11 †,
it may be difficult to top up. If AdBlue ®
is frozen
and there is an active warning indicator, topping up may not be possible. Park the vehicle in a
warm place, e.g. in agarage, until AdBlue ®
has
become liquid again. Topping up is then possible
again. Alternatively, have the AdBlue ®
tank refil-
led at aqualified specialist workshop.
Before driving your vehicle outside Europe, have the AdBlue ®
supply checked at aqualified spe-
cialist workshop.

Important safety notes AdBlue
®
is aw ater-soluble fluid for the exhaust
ga sa ftertreatment of diese lengines. It is:
R non-toxic
R colourless and odourless
R non-flammable If you open the AdBlue
®
tank ,small amounts of
ammonia vapourm ay be released.
Ammonia vapours have apungent odoura nd are
particularly irritating to the skin, mucous mem-
branes and eyes.Y ou may experience aburning
sensation in youre yes,nose and throat. You
may also experience coughing and watery eyes.
Do not inhalea ny ammonia vapours that may be
released. Fill the AdBlue ®
tank only in well-ven-
tilated areas.
Do not swallow AdBlue ®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
awayf rom children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off yours kin with
soap and water.
R if AdBlue ®
comes into contact with youre yes,
immediately rinse them thoroughl ywith clean
water. Seek medica lattention immediately.
R if AdBlue ®
is swallowed, immediately rinse
yourm outh out thoroughly. Drink plenty of
water. Seek medica lattention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
,a nd do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on alevel surface. The
AdBlue ®
tank can only be filledasi ntended
with the vehicle parked on alevel surface.
Fluctuations in capacity willt hus be avoided.
Filling avehicle standing on an uneven sur-
face is not permitted. There is adanger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! Surfaces which have come into contact with

with amoist cloth and cold water. If AdBlue ®
has already crystallised, use asponge and
cold water to clean the area.A dBlue®

G
WARNING
If you mus tbrake the vehicl ewith the parking
brake, the braking distance is considerably
longer and the wheels coul dlock. This increa-
ses the risk of skidding and an accident.
Only use the parking brake to brake the vehi- cle when the service brake is faulty. Do not
apply the parking brake too firmly .Ifthe
wheels lock, release the parking brake until
the wheels begi nturning again. G

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available wit
hlimitations, or not at all. This could affect,
for example, th epower steerin gand th ebrake

of an accident.
Do not switch off th eignitio nwhile driving.
Drive sensibly –savef uel Observe the following tips to save fuel:
X The tyre sshould always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. Short journeys
! Vehicles with
adiesel particle filter: if the
vehicle is mostly driven for short distances, it
is possible that malfunction smay occur dur-
ing the automatic cleaning of the diesel par-
ticle filter. This may lead to fuel collecting in
the engine oil and cause engine failure. There- fore, if you frequently drive short distances,
you should take a20minute trip on amotor-
way or rural road at least every 500km. Brakes
Imp ortant safety notes G
WARNING
If you shift dow nonaslippery road surface in
an attempt to increas ethe engine's braking
effect, the drive wheels coul dlose their grip.
This increases the risk of skidding and having

WARNING
If you select the LOW RANGE off-road gearon as lippery road surface, the wheels coul dlose
traction:
R if you release the accelerator peda lwhen

R if Off-road ABS intervenes when braking
If the wheels lose traction, it willnol onger be
possible to steer the vehicle. This increases
the risk of skidding and having an accident.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.

Take particula rnote of this when driving alad en

Thi sw illu se the braking effect of the engine, so
less braking will be required to maintai nthe
vehicl espeed. Thi srelieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heav yand light loads G
WARNING
The braking system can overheat if you leave you rfoot on the brake peda lwhile driving.
This increases the braking distance and could
even caus ethe braking system to fail .There is
ar isk of an accident.
Never use the brake peda lasafootrest. Do
not simultaneously depress both the brake
peda land the accelerator peda lwhile driving.
! Depressing the brake peda
lconstantly
results in excessive and premature wearto
the brake pads.
If heavy demands are made on the brakes ,do
not park the vehicl eimmediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionall ytest their effectiveness.
To do this, brake more firmly from ahigher speed while paying attention to the traffic con-
ditions .This improves the grip of the brakes.
Wet road surfaces If driving in heavy rain for
aprolonge dperiod of
time withou tbraking, there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depres sthe brake pedalm ore
firmly .Maintai nagreater distance from the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads,
alayer of salt
may form on the brake discs and pads.T his can
increase the braking distance considerably.
R In order to prevent any salt build-up,a pplythe
brakes occasionally whilep aying attention to
the traffic conditions.
R Carefullyd epressthe brake pedalatt he end
of the journey and when starting the next
journey.
R Maintai namuch greater distance to the vehi-
cle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that either are new
or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal.
For safety reasons, Mercedes-Benz recom-
mends only fittingt he following brake discs and
brake pads/linings:
R brake discs that hav ebeena pproved by
Mercedes-Benz
R brake pads/linings that hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle. 116

If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the

R you should drive no faster than walking pace
Off-road fording !
Under no circumstances should you accel-

vehicle interior and damage the vehicle's
electronics and interior equipment.
i You may only drive through fresh water.
R Observe the safety notes (Y page 119) and
general notes (Y page 119) on driving off-
