Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in amanner
that 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 tire wear are affected by these factors:
R operating condition sofyour 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 always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
startingt he engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain asafe 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 00C3of its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel consump-
tion. Environmental concerns and recom-
mendations
Wherever the operating instructions require
you to dispose of materials, first try to regen-
erate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment. Genuine Mercedes-Benz parts

If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is
arisk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on ahigh
curb or an unpave droad
R you drive too fast over an obstacle ,e.g. a
curb or ahole in the road
R ah eavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body,t he under-
carriage, chassis parts, wheels or tires
could be damaged withou tthe damage
being visible. Components damaged in this way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather betwee nthe
underbody and the underbody paneling. 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 on con-
tinuing yourj ourney you notice that driving
safety is impaired, pullo ver and stop the
vehicle immediately,p aying attention to

SRS (Supplementa
lRestraint System)
Introduction 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 consistso f:
R 0075 SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R seat belt force limiters
SRS warning lamp G
WARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with ahigh rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at aq ualified specialist workshop.
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 0075 SRS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out no later than afew seconds
after the engine is started.
The SRS components are in operational read-
iness when the 0075SRS indicator lamp goes
out while the engine is running. There is
amalfunction if:
R the 0075 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0075SRS
warning lamp does not go out after afew
seconds
R the engine is running and the 0075SRS
warning lamp lights up again
Safety guidelines for seat belts, Emer-
gency Tensioning Devices (ETDs) and
air bags G
WARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or suppliedbyana uthorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency Ten-
sioning Devices (ETDs) contain perchlorate
material, which may require special han-
dling and regard for the environment.
Check your national disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
R Air bags and ETDs are designed to function
on aone-time-only basis. An air bag or ETD
that has deployedm ust be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In acrash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any componen tor
part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, front-passenger front air bag Occupant safety

Z

To be classified correctly, the frontp
assenger
must sit:
R with the seat belt fastened correctly
R in ap osition that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by lean-
ing on armrests), OCS may not be able to
approximate the occupant's weight category.
In order to determin ewhether or not the front
passenger has been detected, both the driver and the frontp assenger should observe the
00730074 indicator lamp.
If the front-passenger seat, the seat cover or the seat cushion are damaged, have the nec- essary repair work carried out at an author-
ized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz. G
WARNING
If the 00730074 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or alarger person, ask the passenger to
reposition themselves on the seat so that the
00730074 indicator lamp goes out.
In the event of acollision, the air bag control
unit will not allow front-passenger fronta ir
bag and front-passenger knee bag deploy-
ment when the OCS has classified the front-
passenger occupant as weighing as much as
or less than atypical 12-month-old child in a
standard child restraint or if the front-
passenger seat is classified as being unoccu-
pied.
If OCS has detected that the frontp assenger
weighs the same as or less than atypical 12-
month-old child in astandard child restraint
system, the 00730074indicator lamp lights
up when the engine is started and remains lit. This indicates that the front-passenger front
air bag is deactivated.
If OCS determines that the front-passenger
seat is unoccupied, the 00730074indicator lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger fronta
ir bag and front-
passenger knee bag are deactivated.
If OCS determines that the frontp assenger
weighs more than atypical 12 montho ld child
in as tandard child restraint system and clas-
sifies this as asmall person (e.g. ateenager or
small adult), the 00730074indicator lamp
lights up for approximately 6seconds when
the engine is started. Dependin gonoccupant
weight sensor readings from the seat, it will
then remain illuminated or go out. If the
00730074 indicator lamp is illuminated, the
front-passenger fronta ir bag is deactivated.
With the 00730074 indicator lamp out, the
front-passenger fronta ir bag and front-
passenger knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person, the 00730074 indicator lamp lights up for
approximately 6seconds when the engine is
started and then goes out. This shows that the
front-passenger fronta ir bag and front-
passenger knee bag are activated.
If the 00730074 indicator lamp is illuminated,
the front-passenger fronta ir bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 00730074 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
R in the event of certain frontal impacts
R if the impact exceeds apreset deployment
threshold
R independently of the other air bags
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the frontp assenger's weight category as
determined by the OCS
