Protection of the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
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. Therefore,
please bear the following in mind:
Operating conditions:
R avoid short trips, as these increase fuel
consumption.
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle.
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be 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 when the vehicle
is stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking.
R change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R switch off the engine in stationary traffic.
R monitor the vehicle's fuel consumption.
Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle
to dispose of it in an environmentally-respon-
sible manner in accordance with the Euro-
pean Union (EU) End of Life Vehicles Direc-
tive.
There is a network of return points and dis-
assembly plants available. You can return
your vehicle to these plants free of charge.
This makes a valuable contribution to the
recycling process and the conservation of
resources.
For further information on recycling old vehi-
cles, recovery and the terms of the policy,
visit the Mercedes-Benz homepage.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Introduction21ZProCarManuals.com

Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop.
If you use parts, tyres and wheels as well as
accessories relevant to safety which have not
been approved by Mercedes, the operating
safety of the vehicle could be jeopardised.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. Only
use genuine Mercedes-Benz parts or parts of
equal quality. Only use tyres, wheels and
accessories that have been specifically
approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles, even if they
have been independently or officially
approved.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected
Always specify the vehicle identification num-
ber (VIN) ( Y page 336) and the engine num-
ber ( Y page 336) when ordering genuine
Mercedes-Benz parts.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.
Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe-
cific differences are possible. Note that your
vehicle may not be fitted with all features
described. This is also the case for systems
and functions relevant to safety. Therefore,
the equipment on your vehicle may differ from
that in the descriptions and illustrations.
The original purchase contract documenta-
tion for your vehicle contains a list of all of the
systems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are
important documents and should kept in the
vehicle.

Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or necessary repairs car-
ried out, this could result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop.
22IntroductionProCarManuals.com

Do not connect any equipment to a diagnos-
tics connection in the vehicle.GWARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.

vehicles. The quality or safety of the vehicle
is improved as a result of the inspection.
Mercedes-Benz can only inform you about
vehicle checks if it has your registration data.
It is possible that your vehicle has not yet
been registered in your name in the following
cases:
R if your vehicle was not purchased at an
authorised specialist dealer.
R if your vehicle has not yet been examined
at a Mercedes-Benz Service Centre.

Engine compartment
Bonnet
Important safety notes
GWARNING
An unlocked bonnet may open while driving
and block your view. There is a risk of an acci-
dent.
Never unlock the bonnet while driving.
GWARNING
When being opened and closed, the bonnet
may suddenly fall into the closed position.
There is a risk of injury to persons in the range
of movement of the bonnet.
Open and close the bonnet only when nobody
is in the range of movement.
GWARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the following compo-
nents.
GWARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking
service products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in
the engine compartment, leave the bonnet
closed and notify the fire brigade.GWARNING
There are parts in the engine compartment
that move. Certain components may continue
to run even if the ignition is switched off or
may suddenly start again, e.g. the radiator
fan. There is a danger of injury.
If you need to access the engine compart-
ment:
R switch off the ignition
R never enter the danger area of moving com-
ponents, e.g. the rotation area of the fan
R keep items of clothing away from moving
parts
GWARNING
The ignition system and the fuel injection sys-
tem operate with a high voltage. If you touch
the live components, you could receive an
electric shock. There is a danger of injury.
Never touch components of the ignition sys-
tem or the fuel injection system when the
ignition is switched on.
Active bonnet (pedestrian protection)
Operating principle
! Once triggered, an active bonnet must be
reset at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. The
active bonnet function will then be availa-
ble again. The additional pedestrian pro-
tection provided by the active bonnet will
then be restored.
The active bonnet is only available in certain
countries.
The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
