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. Use
only 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 354). 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
Important safety notes
G
WARNING
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. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. 22
Introduction

G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring could effect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
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 visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for. If the underbody panelling is damaged,
combustible 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 specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted 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 rel-
evant conditions of Directive 1999/5/EC.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi- fied according to the currently valid version of Regulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. Introduction
23 Z

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 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

Introduction

Implied warranty
! Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions are not covered either by
Mercedes-Benz implied warranty or by the
New or Used-Vehicle Warranty. Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture This data is of an exclusively technical nature
and can be used to:
R assist in recognising and rectifying faults
and defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem- ory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Introduction

Important safety notes
G
WARNING
Modifications to the restraint systems could
result in them not functioning properly any more. The restraint systems could then no
longer protect vehicle occupants as they are
designed to do and could fail in the event of an accident or activate unexpectedly, for exam-
ple. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to modify the wiring as well as
electronic components or their software.
The airbag system can be adapted for a per-
son with disabilities. For further information,
consult a Mercedes-Benz Service Centre.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 41). They reduce the risk of injury in
specific, pre-defined types of accident situa-
tions and thereby increase occupant safety.
However, seat belts and airbags generally do
not protect against objects penetrating the
vehicle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 98)
R the seat belt has been fastened properly
(Y page 46)
R the airbags can inflate properly if they are
deployed (Y page 42)
R the steering wheel is adjusted properly
(Y page 104)
R the restraint systems have not been modi-
fied
An airbag increases the protection of vehicle
occupants wearing a seat belt. However, air-
bags are only an additional restraint system
that complements, but does not replace, the
seat belt. All vehicle occupants must wear
their seat belts correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents. For example, if the protective capacity of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy. 40

WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the automatic transmission out of
parking position P.
R shift the manual transmission into neutral.
R start the engine.
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 or animals unattended in the vehicle.Always keep the key out of reach of children. 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.
If a child is travelling in your vehicle, secure
the child using a child restraint system which is appropriate to the size, age and weight of
the child. In order to correctly secure the child
in the child restraint system, always comply
with the child restraint system manufactur-
er's installation instructions. You should pref- erably fit the restraint system to a suitable
rear seat. Make sure that the child is securedfor the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 59). You can obtain further infor-
mation about the correct child restraint sys-
tem from any Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre.
Child restraint system on the front-
passenger seat G
WARNING
If the front-passenger front airbag is not dis-
abled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously or even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger front airbag
when it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys- tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R and you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible. When doing so,
ensure that the shoulder belt strap from the
belt outlet on the vehicle is routed towards
the front to the shoulder belt guide on the
child restraint system. Set the belt height
adjustment so that the belt strap is routed
towards the front along the bottom. 52
