Environmental protection
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 end-of-life
vehicle for environmentally-friendly disposal in
accordance with the European Union (EU) End-
Of-Life Vehicles Directive.
A network of vehicle take-back points and dis-
mantlers has been established for you to return
your vehicle. You can leave it at any of these
points free of charge. This makes an important
contribution to closing the recycling circle and
conserving resources.
For further information about the recycling and
disposal of end-of-life vehicles, and the take-
back conditions, please visit the national
Mercedes-Benz website for your country. 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. 26
Introduction

If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears on the instrument
cluster (Y page 268). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front airbag both before and during the journey.
If a person sits in the passenger seat, he/she
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with his/her
back against the seat backrest
R with his/her feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers his/her weight by supporting him-
self/herself on a vehicle armrest
R sits in such a way that his/her weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag then does not
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa- bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child in a rearward-facing child
restraint system on the co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag has been disabled. The
PASSENGER AIR BAG OFF indicator lamp
must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
Further information can be found under "Prob-
lems with the automatic front-passenger front
airbag deactivation system" (Y page 54). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt Occupant safety

passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso-
lutely necessary to fit a child restraint system to the front-passenger seat, always observe the
information on the "Automatic front-passenger
front airbag deactivation system" (Y page 50).
You can thus avoid the risks that could arise as
a result of:
R a child restraint system that is not detected
by the automatic front-passenger front airbag
deactivation system
R unintentional disabling of the front-passenger
front airbag
R unsuitable positioning of the child restraint
system, e.g. too close to the dashboard Please observe the warning notice on the
front-passenger sun visor; see illustration. G
WARNING
If you secure a child in a rearward-facing child
restraint system on the co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag has been disabled. The
PASSENGER AIR BAG OFF indicator lamp
must be lit.
NEVER use a rearward-facing child restraint on a
seat protected by an ACTIVE FRONT AIRBAG;
DEATH or SERIOUS INJURY to the child can
occur.
If the PASSENGER AIR BAG OFF indicator lamp
goes out, the front-passenger front airbag is
enabled (Y page 43).

61Safety Z

If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard on the front-
passenger side. The sticker is visible when you
open the front-passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps light
up briefly. However, they have no function and
do not indicate that there is an automatic front- passenger front airbag deactivation system.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 62).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 62) and "Forward-facing child
restraint system" (Y page 62) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 62).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if
the PASSENGER AIR BAG OFF indicator lamp is lit continuously (Y page 43) is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 62) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must, as far as possible, lie flat against the backrest of the front-passenger
seat. The child restraint system must not touch the roof or be put under strain by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Always make sure that the shoulder belt strap is correctly routed from the vehicle belt outlet to
the shoulder belt guide on the child restraint
system. The shoulder belt strap must be routed
forwards and downwards from the vehicle belt
outlet. If necessary, adjust the vehicle belt out-
let and the front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 62) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems that are approved in
accordance with ECE standard ECE R44 are per-
mitted for use in the vehicle.

Important safety notes
G
WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage.
! Only use fuses marked with an "S" for the
fuse box in the engine compartment and
under the rear bench seat. Components or
systems could otherwise be damaged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper- ation of the fuses.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components in the circuit and their functions will fail.
Blown fuses must be replaced with fuses of the
same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed in the fuse allocation chart.
The fuse allocation chart is located in the fuse
box under the rear bench seat (Y page 360).
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre. Before replacing a fuse
