Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in a manner
which takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine with the vehicle
stationary.
R drive carefully and maintain a safe distance
from the vehicle in front. R
avoid frequent, sudden acceleration.
R change gear in good time and use each gear
only up to Ôof its maximum engine speed.
R switch off the engine in stationary traffic. Returning an end-of-life vehicle
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles with a gross vehicle weight of up to
3.5 t, in accordance with national regulations.
For several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and re-use.
There is a network of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The methods employed in vehicle and
parts recycling are constantly being devel-
oped and improved. This means that your
Mercedes-Benz will also continue to meet
even the increased recycling quotas in the
future in good time. You can obtain further
information from your national Mercedes-
Benz homepage or your national hotline num-
ber. Owner's Manual
General notes
Before you first drive off, read this Owner's
Manual carefully and familiarise yourself with
your vehicle.
For your own safety and a longer vehicle life,
follow the instructions and warning notices in
this manual. Disregarding them may lead to
damage to the vehicle or personal injury. 20

engine, which could lead to a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines .Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.

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.
Checklist before driving off-road !
If the engine oil warning lamp lights up
during the journey, stop the vehicle in a
safe place as soon as is possible. Check the
engine oil level. The warning given by the
engine oil warning light must not be
ignored. Continuing your journey when the
symbol is shown may result in engine dam-
age.
X Engine oil level: check the engine oil and
top it up if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.
X G3 50 BlueTEC: have the AdBlue ®
level
checked at a qualified specialist workshop
(Y page 160).
X Tyre-change tool kit: check that the jack
is working and make sure you have the
wheelbrace, a robust tow cable and a fold-
ing spade 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 Carry a sound spare wheel. 170
Driving tipsDriving and parking

There are several ways to deactivate variable
SPEEDTRONIC:
X
Briefly press the cruise control lever for-
wards B.
or
X Briefly press the cruise control lever in the
direction of arrow A.
LIM indicator lamp ;in the cruise control
lever goes out. Variable SPEEDTRONIC is
deactivated.
Cruise control is selected.
It is not possible to deactivate variable
SPEEDTRONIC by braking.
Variable SPEEDTRONIC is deactivated auto-
matically if you depress the accelerator pedal
beyond the pressure point (kickdown), but
only if your curren tspeed does not differ by
more than 20 km/h from the stored speed.
G 350 BlueTEC: you will hear a warning tone.
Permanent SPEEDTRONIC You can use the on-board computer to limit
the speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed ( Ypage 223).
Shortly before the store dspeed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly iden-
tify other road users and complex traffic sit-
uations.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS. G
WARNING
DISTRONIC PLUS brakes your vehicle with up
to 40% of the maximum braking force. If this
braking force is insufficient, DISTRONIC PLUS
warns you visually and audibly. There is a risk
of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
If you fail to adapt your driving style, DIS-
TRONIC PLUS can neither reduce the risk of
acciden tnor override the laws of physics.
DISTRONIC PLUS cannot take account of
road, weather and traffic conditions. DIS-
TRONIC PLUS is only an aid. You are respon-
sible for the distance to the vehicle in front,
for vehicle speed, for braking in good time and
for staying in lane. Only engage DISTRONIC
PLUS when the current road, weather and
traffic conditions permit it to be done safely,
and adapt your driving style accordingly.
Drive carefully and maintain a suitable dis-
tance to the vehicle in front.
If DISTRONIC PLUS detects a risk of collision
but cannot sufficiently decelerate the vehicle
in order to maintain the set distance, you will 182

Course-correcting brake application
G
WARNING
Active Blind Spot Assist is only an aid
designed to assis tdriving. It is not a substitute
for attentive driving. Automatic braking by the
system may not always be sufficient to avoid
a collision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapt yourd riving style to suitthe
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. If a course-correcting brake application
occurs, red warning lamp
:flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;appears in the
multifunction display.
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is designed to help you avoid a col-
lision.
The course-correcting brake application is
available in the range between 30 km/h and
200 km/h.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R a vehicle approaches too closely on the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you brake or accelerate decisively.
R a driving safety system intervenes, e.g.
ESP ®
.
R ESP ®
is deactivated.
R the LOW RANGE off-road gear is activated.
R a loss of tyre pressure has been detected.
