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

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

WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop
A qualified specialist workshop has the nec-
essary special skills, tools and qualifications
to correctly carry out any necessary work on
your vehicle. This particularly applies to work
relevant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a qualified specialist workshop:
R work relevant to safety
R service and maintenance work R
repair work
R modifications, installations and conver-
sions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
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.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. You can do this at a Mercedes-Benz
Service Centre, for example. Correct use
If you remove any warning stickers, you or
others could fail to recognise certain dangers.
Leave warning stickers in position.

WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system
for a person with physical disabilities, contact a Mercedes-Benz Service Centre for details. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the engine is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig- gered at all in the event of an accident with a
high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG OFF indicator
lamp PASSENGER AIR BAG OFF indicator lamp
:
and PASSENGER AIR BAG ON indicator
lamp ;are part of the automatic child seat
recognition on the front-passenger seat.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled.
When the ignition is switched on, the
PASSENGER AIR BAG ON indicator lamp
lights up:
R briefly, if the sensor system for the auto-
matic child seat recognition in the front-
passenger seat detects a special
Mercedes-Benz child restraint system with
a transponder.

Important safety notes
If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to
cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit-
ting properly. Particular attention must be
paid to children.

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 60)
R BAS ( Brake Assist System) (Y page 61)
R BAS PLUS ( BrakeAssist System PLUS)
(Y page 61)
R Adaptive brake lamps (Y page 62)

(Y page 62)
R EBD ( electronic brake force distribution)
(Y page 66)
R ADAPTIVE BRAKE (Y page 66)
R PRE-SAFE ®
Brake (Y page 66) 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 the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-
fully.
i 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 atten-tion to the notes on tyres, recommended
minimum tyre tread depths etc.
(Y page 314). In wintry driving conditions, always use
winter tyres (M+S tyres) and, if necessary,
snow chains. Only in this way will the driv-
ing 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 yellow !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 60). 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.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 252) and
display messages which may be shown in the
instrument cluster (Y page 223).
ABS works from a speed of about
8 km/hupwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently. 60
Driving safety systemsSafety

ESP
®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified to keep the vehicle on the desired course within
physical limits. ESP ®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilise the vehicle during braking.
ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 60).
ETS traction control is part of ESP ®
.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP ®
.
i AMG vehicles:
your vehicle may be
equipped with 20-inch tyres on the rear
axle. If replaced with a 19-inch tyre, ETS
may intervene noticeably sooner for the
first few kilometres. After approximately
10 km ETS will function as usual again.
Information on the dimensions and types of
wheels and tyres for your vehicle can be
found under "Wheel/tyre combinations"
(Y page 328).
Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop. !
When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by ESP ®
may otherwise destroy the brake system.
When towing your vehicle with the rear axle
raised, observe the notes on
ESP ®
(Y page 308).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 254) and display messages which
may be shown in the instrument cluster
(Y page 223).
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Characteristics of ESP ® General notes
If the
÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the accel-
erator pedal as far as is necessary.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its pre-
viously selected status. Example:if ESP®
was deactivated before the engine was Driving safety systems
