Protection of the environment
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 monitor the vehicle's fuel consumption.
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. 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. Returning an end-of-life vehicle
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles with a gross vehicle weight of up to
3.5 t, in accordance with national regulations.
For several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and re-use.
There is a network of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Owner's Manual. Country-specific
deviations are possible. Please note that your
vehicle may not be equipped with all features
described. This is also the case for systems
and functions relevant to safety. The equip-
ment in your vehicle may therefore differ from
that shown in the descriptions and illustra-
tions.
All the systems found in your vehicle are listed
in the original purchase agreement of your
vehicle. 20
Introduction

Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and the Service Booklet
are important documents and should be kept
in the vehicle. Operating safety
Safety notes
G
WARNING
All work on the vehicl eand, in particular, work
relevant to safety or on safety-related sys-
tems must be carried ou tataqualified spe-
cialist workshop. The specialist workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. G
WARNING
Some safety systems only function when the
engine is running. You should therefore never
switch off the engine when driving .Otherwise,
the safety systems of your vehicle may not
function correctly and as a result will no lon-
ge rp rotect you and other persons as inten-
ded. In addition, there is a risk that you may
lose control of yourv ehicle and thus cause an
accident. G
WARNING
Work carried out incorrectly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tecty ou and other persons as intended. In
addition, there is a risk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alterations to the vehicle, e.g.
installations or modifications, should there- fore be carried out at
aqualified specialist
workshop. G
WARNING
If work on electronic equipment and its soft-
ware is carried out incorrectly, this equipment
could stop working .The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at a qualified specialist workshop. General notes
The following information applies to all com-
ponents of this vehicle that receive and/or
transmit radio waves and to COMAND:
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.
The components are approved by the vehicle
manufacturer in accordance with European
Automotive EMC Directive 95/54/EC. Oper-
ation according to its intended purpose is
thus approved for your vehicle. The equip-
ment does not require certification.
The equipmen tconforms to the relevant
equipment-specific EMC specifications in
accordance with the following European
standards:
R EN 55013
R EN 55020
Therefore, adherence to the relevant specifi-
cations for electromagnetic compatibility is

ponents and interference to your compo-
nents caused by other electrical/electronic
components can be largely prevented. Diagnostics connection
G
WARNING
If you connect equipment to the diagnostics
connection, it can affect the operation of the
vehicle systems. This can impair the operating
safety of your vehicle while driving. There is a
risk of accident.
Do not connect any equipment to the diag-
nostics connection. G
WARNING
Loose equipment or equipment cables that
are connected to the diagnostics connection
can obstruct the area around the pedals. The
equipment or the cables could get between
the pedals in the event of sudden braking or
acceleration. As a result, the movement of the
pedals may be impaired. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to emis-
sions monitoring information being reset.
This may lead to the vehicle failing to meet
the requirements of the nex temissions test
during the main inspection. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary specialist knowledge, tools and quali-
fications to correctl ycarry out the work required on your vehicle

tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tampe rwith elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might not
be triggered in the event of an accident with
a high rate of vehicle deceleration.
A malfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds.
R the engine is running and the 6SRS
warning lamp lights up again. In this case, have SRS checked immediately
at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the firs
tstage of a collision, the airbag
control uni tevaluates important physical
data relating to vehicle deceleratio noraccel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control uni tpre-emptively triggers the
beltt ensioners in the first stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc-
tion, the fron tairbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. In the firs tdeployment stage,
the fron tairbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deploymen tthreshold is exceeded within a
few milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take place in
good time at the start of the collision.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident. The dif-
ferent airbag systems work independently
of each other. Occupant safety
