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-responsible
manner in accordance with the European Union (EU) End of Life Vehicles Directive.
There is a network of return points and disas-
sembly 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
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs
or welding. You could impair the operating
efficiency of the restraint systems.
Have accessories retrofitted at a qualified
specialist workshop. 24
Genuine Mercedes-Benz partsIntroduction

Always have work on electrical and electronic
components carried out at a qualified special-ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed for.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all compo-
nents of the vehicle and the information sys-
tems and communication devices integrated
into the vehicle which receive and/or transmit
radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant with
the basic requirements and all other relevant
conditions of Directive 1999/5/EC. You can
obtain further information from any Mercedes-
Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehicle
components has been checked and certified
according to the currently valid version of Reg-
ulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended for the connection of diagnostic equipment at a
qualified specialist workshop. G
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 equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. 26

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 running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
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
:is
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.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the installed
child restraint system, and the age and size of the child. Therefore, it is imperative to
observe the notes on "Children in the vehicle"
(Y page 49). There you will also find infor-
mation on rearward or forward-facing child
restraint systems on the front-passenger
seat.
R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. Be sure to
observe the notes on "Seat belts"
(Y page 38) and "Airbags" (Y page 42).
There you can also find information on the
correct seat position.
Observe the information on automatic child seat recognition in the front-passenger seat
(Y page 51). Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi- cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners for the front seat belts and the
outer seat belts in the rear
R belt force limiters for the front seat belts and
the outer seat belts in the rear 38
Occupant safetySafety

The PRE-SAFE
®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if DISTRONIC PLUS indicates an intention to
pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat. Children are
generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate 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 sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(Y page 39) and the notes on how to use the seat
belt properly (Y page 40). Children in the vehicle

Children in the vehicleSafety

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 vehicle 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.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only
brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). 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, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 256) and display mes-
sages which may be shown in the instrument
cluster (Y page 230).
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions; this serves as a
reminder to take extra care while driving. BAS (Brake Assist)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Brakes X
Keep the brake pedal depressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist PLUS) with
Cross-Traffic Assist
General notes BAS PLUS can help you to minimise the risk of a
collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
i Pay attention to the important safety notes
in the "Driving safety systems" section
(Y page 61).
BAS PLUS is only available on vehicles with the
Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational. 62
