(BlueTEC vehicles only)
General notes To function properly, BlueTEC exhaust gas after-
treatment must be operated with the reducing
agent AdBlue ®
. Topping up AdBlue ®
is part of
the maintenance work. Under normal operating
conditions, a full tank of AdBlue ®
should last
until the next service due date.
When the supply of AdBlue ®
is down to approx-
imately 3.8 l, the Refill AdBlue See Own‐ Refill AdBlue See Own‐
er's Manual er's Manual message is shown in the multi-
function display.
X Add at least 3.8 lof AdBlue ®
.
X Switch on the ignition for at least 60 seconds.
X Start the engine.
i You can also have the AdBlue ®
tank refilled
at a qualified specialist workshop.
Before driving your vehicle outside Europe, have
the AdBlue ®
supply checked at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
Important safety notes AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released. Ammonia vapours have a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning sensation in your eyes, nose and throat. You
may also experience coughing and watery eyes.
Do not inhale any ammonia vapours that may be
released. Only fill the AdBlue ®
tank in well-ven-
tilated areas.
Do not swallow AdBlue ®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
away from children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention 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 ®
, and 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 a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components. 166
RefuellingDriving and parking
!
Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with a moist cloth and cold water. If AdBlue ®
has already crystallised, use a sponge and
cold water to clean the area. AdBlue ®
residue
crystallises after a certain amount of time and soils the affected surfaces.
! AdBlue ®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam-
age.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automati-
cally during filling at a filling pump, the AdBlue ®
tank has been completely filled. Do not fill the
AdBlue ®
tank any further. AdBlue ®
may leak
out.
To avoid transporting already opened refill con-
tainers in the vehicle, completely empty refill
bottles or canisters when filling the AdBlue ®
tank, if possible.
Further information on AdBlue ®
(Y page 384).

AdBlue ®
refill canisters are available at many
filling stations or at a qualified specialist work-
shop. AdBlue ®
refill canisters are often sold with
a filler hose. A filler hose that does not exactly fit
the vehicle's AdBlue ®
tank offers no overfill pro-
tection. AdBlue ®
may leak out as a result of
overfilling. Mercedes-Benz offers a special dis-
posable hose with overfill protection. You can
obtain this from any Mercedes-Benz Service
Centre. AdBlue ®
is available in a variety of con-
tainers and receptacles. Use the disposable
hose only with the Mercedes-Benz AdBlue ®
refill
canisters.

AdBlue ®
refill bottles are available at many fill-
ing stations or at a qualified specialist work-
shop. Refill bottles without a threaded seal offer
no overfill protection. AdBlue ®
may leak out as a
result of overfilling. Mercedes-Benz offers spe-
cial refill bottles with a threaded cap. These are
available at any Mercedes-Benz Service Centre. Parking
Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle 168
ParkingDriving and parking
R
Do not stray from marked routes or paths.
R Observe the notes on off-road fording
(Y page 175).
i Information about retrofitting special all-ter-
rain tyres is available from any qualified spe-
cialist workshop.
i Do not use the HOLD function when driving
off-road, on steep uphill or downhill gradients or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur- faces.
Checklist before off-road driving X
Engine oil level: check the engine oil and top
it up if necessary.
When driving on steep gradients, the oil level must be sufficiently high to ensure a correct
oil supply in the vehicle.
X AdBlue ®
tank (BlueTEC vehicles): check the
level and top up if necessary (Y page 166).
X Tyre-change tool kit: check that the jack is
working and make sure that the wheel
wrench, a robust tow cable and a folding
spade are in the vehicle.
X Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tyres.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Wheels: dented or bent wheels can lead to a
loss of tyre pressure and damage to the tyre
bead. Before driving off-road, check the
wheels and replace them if necessary.
Checklist after off-road driving !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Driving over rough terrain places greater
demands on your vehicle than driving on normal
roads. After driving off-road, check the vehicle.
This allows you to detect damage promptly and reduce the risk of an accident to yourself and
other road users.
X If the Off-road orOff-road Plus drive pro-
gram is selected: select the Individual,Sport,
Comfort orSlippery drive program
(Y page 155).
X Deactivate the LOW RANGE offroad gear
(Y page 230).
X Deactivate DSR (Y page 227).
X Lower the vehicle level again to a level suita-
ble to the road conditions, e.g. to the normal
level.
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels and tyres with a water jet
and remove any foreign objects.
X Clean the wheels, wheel arches and the vehi-
cle underside with a water jet; check for any
foreign objects and damage.
X Check whether twigs or other parts of plants
have become trapped. These increase the risk
of fire and can damage fuel pipes, brake
hoses or the rubber bellows of the axle joints
and propeller shafts.
X After the trip, examine without fail the entire
undercarriage, wheels, tyres, brakes, body-
work structure, steering, chassis and exhaust
system for damage.
X After driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.
X If you detect strong vibrations after driving
off-road, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
Driving on sand Observe the following rules when driving on
sand:
R Select the Offroaddrive program (vehicles
without Off-Road Engineering package)
(Y page 228).
R Select the Offroaddrive program (vehicles
with Off-Road Engineering package)
(Y page 229).
R Select a higher vehicle level.
R Avoid high engine speeds.
R Use the left-hand steering wheel gearshift
paddle to shift to a lower gear appropriate to
the terrain. 178
