Protection of the environment
General notes
H
Environmental 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 Ôof 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
H
Environmental 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 Introduction
21 Z

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.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes. 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 therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or
independently approved by a testing centre.
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) when ordering genuine Mercedes-
Benz parts (Y page 386). Owner's Manual
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. Operating safety

Pets in the vehicle
G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push a button
or a switch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is a risk of an accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 73)
R BAS ( Brake Assist System) (Y page 74)
R COLLISION PREVENTION ASSIST PLUS
(Y page 74)
R Adaptive brake lamps (Y page 77)
R ESP ®
(Electronic StabilityProgram)
(Y page 77)
R EBD ( electronic brake force distribution)
(Y page 79)
R ADAPTIVE BRAKE (Y page 79)
R STEER CONTROL (Y page 79) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for maintaining
the distance to the vehicle in front, for vehicle
speed, for braking in good time, and for stay- ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions and maintain a safe distance from the
vehicle in front. Drive carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tyres and the
road surface. Please pay special attention to
the notes on tyres, recommended minimum
tyre tread depths etc. (Y page 352).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety systems described in this section work as
effectively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 73). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents. Driving safety systems

Adaptive Highbeam Assist
General notes You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
Once the system no longer detects any other vehicles, it switches on the main-beam head-
lamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier In very rare cases, Adaptive Highbeam Assist
recognises road users too late or not at all. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

General notes Only THERMOTRONIC automatic climate con-
trol features the "Control climate control
automatically" function.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only deactivate the "Cooling with air-dehu-
midification" function briefly.
