Protection of the environment
Notes
H
Environmental note
Daimler's declared policy is one of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in a manner
which takes the requirements of both nature
and humanity into account.
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. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have maintenance work carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine with the vehicle
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 end-of-life vehicles
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 reuse.
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
differences are possible. Please note that
your vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. 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 Introduction

Safety notes
G
WARNING
All work on the vehicle and, in particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified 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-
ger protec tyou and other persons as inten-
ded. In addition, there is a risk that you may
lose control of your vehicle 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-
tect you 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. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary specialist knowledge, tools and quali-
fications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.
Observe the information in the Service Book-
let.
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 alterations, installation work and modifica-
tions
R work on electronic components
Mercedes-Ben zrecommends 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 to improve their quality or safety.
If you did not purchase your vehicle from an
authorised specialist dealer and your vehicle
has never been inspected at a Mercedes-
BenzS ervice Centre, it is possible that your
vehicle is not registered in your name with 26

WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration force being sufficien tto trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with 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 activated unintentionally or may 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. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of a collision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R
duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats 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 front airbags 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 Occupant safety

Belt warning for driver and front
passenger The
7 seatbelt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver or th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the fron tpassenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrumen tcluster, seat
belt" (Y page 273).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the display
indicates a fastened seat belt. If a seat belt is
not fastened or if a seat is not occupied, the
ý symbol is displayed.
The rear-compartment seat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again. You can also cancel the rear seat belt status
indicator immediately (Y
page 232).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupan
tis
reduced.
The belt force limiters on the front seats are
synchronised with the front airbags. They
take on a part of the deceleration force,
resulting in the force exerted on the occupant
being distributed over a greater area.
The beltt ensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 45).
R the belt tongue is engaged in the buckle on
each of the three-poin tseat belts in the
front.
The belt tensioners on the seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R if, in the event of a head-on or rear-end col-
lision, the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle deceler- 54
Occupant safetySafety

Vehicles with COMAND and navigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 363).
Vehicles without COMAND and a navigation
system and vehicles for Australia:t he radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities (Y page 226).
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational; see "Radar sensor system" in the
index. G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases.
There is a risk of an accident. Always pay
careful attention to the traffic situation and be
ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorbike
R a vehicle travelling in front on a different
line G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, BAS PLUS may not intervene in
critical situations. There is a risk of an acci-
dent. Always pay careful attention to the traf-
fic situation and be ready to brake. Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the brake
system remains available with full brake
boosting effect and BAS.
Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he hazard warning
lamps switch off automatically if you travel
faster than 10 km/h .You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 111). ESP
