AdBlue
®
Important notes on use To function properly, BlueTEC exhaust gas
aftertreatment 1
mus tbe operated with the
reducing agent AdBlue ®
.
When the supply of AdBlue ®
is almost used
up, the Refill AdBlue See Owner's Man‐
ual message is shown in the multifunction
display. Awarning tone also sounds.
If the Refill AdBlue No start in: .. km message is shown in the multifunction dis-
play, you can still driv ethe vehicle over the
distance shown. Awarning tone also sounds.
If the AdBlue ®
is no ttopped up, you will sub-
sequently be unable to start the engine.
After receiving the warning message, it is
preferable to fill the AdBlue ®
tank with
10 litres of AdBlue ®
.Int his way, you can
ensure that the AdBlue ®
supply lasts until the
next regular service date.
Further information about BlueTEC exhaust
gas aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Ben zService
Centre.
Topping up 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 aftertreatmen tsystem.
! In order to fill the AdBlue ®
tank, the vehi-
cle mus tbe 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 avoi-
ded. Filling a vehicle standing on an uneven
surface is not permitted. There is a danger
of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatmen tcom-
ponents. !
Do not fill the AdBlue ®
container with a
pump nozzle.
! If there are steep gradients while driving
off-road, a sufficient filling level in the
AdBlue ®
tank must be ensured. Make sure
for this reason that there is a minimum fill
level of ten litres before driving off-road.
! 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 sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank.IfA dBlue®
is
added to the fuel tank, this can lead to
engine damage.
If you open the AdBlue ®
tank cap, small
amounts of ammonia vapour may be
released.
Ammonia vapours have a pungen todour and
are particularly irritating to:
R skin
R mucous membranes
R 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 any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.

Off-road driving
Important safety notes G
WARNING
If you drive up a steep incline at an angle or
turn on a steep incline, the vehicle could slip
sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line
of fall (upwards or downwards in a straight
line) and do not turn.
! G350 BlueTEC:
The level in the AdBlue ®
tank needs to be
sufficiently high to compensate for driving
at extreme angles when driving off-road.
Before driving off-road, make sure that the
tank contains a minimum of ten litres.
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could get
into the brakes. This may lead to a reduction
in braking performance or total brake failure
as a result of increased wear. The braking
characteristics will vary, depending on the
substances that get int othe brakes. Cleant he
brakes after driving off-road. If you notice
grinding noises or a reduction in braking per-
formance, have the brake system checked at
a qualified specialist workshop immediately.
Adapt your driving style to the altered braking
characteristics.
Driving off-road increases the possibility of
damage to the vehicle, which may cause
assemblies or systems to fail. Adapt your
driving style to the conditions of the terrain.
Drive carefully. Have vehicle damage rectified
immediately at a qualified specialist work-
shop. Observe the following when on hilly roads:
R
Do not shift the transmission to position
N.
R If the gradient is too steep for your vehicle,
back up in reverse gear.
R Do not continuously depress the brake
pedal, as doing so could cause you to lose
control.
General notes H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section before driving your vehicle
off-road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:
R 4ETS (Y page 62)
R Transfer case (Y page 201)
R Differential locks (Y page 204)
Observe the following notes:
R stop your vehicle and, if necessary, shift the
transfer case to LOW
RANGE(Y page 202) before driving off-
road.
R AMG vehicles: to shift the transfer case to
LOW RANGE, deactivate the ECO start/
stop function (Y page 146).
R engage the differential locks, if necessary
(Y page 204)
i ABS,4 ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged.
This allows the front wheels to lock briefly,
so tha tthey can dig into a loose surface.
However, please note that locked wheels
skid and can no longer steer. Driving tips
169Driving and parking Z

R
Chec kthat items of luggage and loads are
stowed safely and are well secured
(Y page 271).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Always keep the engine running and in gear
when driving on a downhill gradient.
R Always keep the engine running and in gear
when driving on a slope.
R Drive slowly and evenly, if necessary at
walking pace.
R Ensure that the wheels are in contact with
the ground at all times.
R Drive with extreme care on unknown off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Check the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine.
R Look out for obstacles such as rocks, holes,
tree stumps and furrows.
R Always keep the doors, the rear door or
tailgate (G-Class Cabriolet), the side win-
dows and the sliding sunroof closed while
the vehicle is in motion.
R Switch off cruise control and variable
SPEEDTRONIC.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the ter-
rain, the slower your speed should be.
R Drive slowly and at a constant speed
through the water. Ensure that a bow wave
does not form as you drive.
R On sand, drive quickly to overcome the roll-
ing resistance. Otherwise, the vehicle could
dig itself into the sand.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion. R
Avoid high engine speeds. Drive at appro-
priate engine speeds.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tyres is available from any qualified
specialist workshop.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra-
dients or on slippery or loose surfaces. The
HOLD function cannot hold the vehicle on
such surfaces.
