Protecting 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 am anner
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 sofy our vehicleR
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
startin gt he engine.R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain as afe 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

systems, e.g. the brake system. Use only genu-
ine Mercedes-Benz parts or parts of equa lq ual-
ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been spe-
cifically developed ,m anufactured or selected
for and adapted to Mercedes-Benz vehicles.
Therefore, only genuine Mercedes-Benz parts
should be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers maintain
as upply of genuine Mercedes-Benz parts for
necessary service and repair work. In addition,
strategically located parts delivery centers pro-
vide quick and reliable parts service.
Always specify the vehicle identification number
(VIN) when ordering genuine Mercedes-Benz
parts ( Y

Operating safety
Important safet yn otes
G WARNING
If you do not have the prescribed service/
maintenanc ew ork or any required repairs
carried out, this can result in malfunctions or
system failures. There is ar isk of an accident.
Always have the prescribed service/mainte-
nanc ew ork as well as any required repairs
carried out at aq ualified specialist workshop.
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 ar isk
of fire.
When driving off road or on unpaved roads,
chec kt he 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 can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardiz et he operatin gs afety of
the vehicle. There is an increased risk of an
acciden ta nd injury.
Never tamper with the wiring as well as elec-
tronic component sort heir software. You
should have all work to electrical and elec-
tronic equipment carried out at aq ualified
specialist workshop. ! There is ar isk of damage to the vehicle if: R
the vehicle becomes stuck ,e .g. on ah igh
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb, as peed bump or ap othole in the roadR
ah eavy objec ts trikes the underbody or
parts of the chassis
In situation sl ike this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the loads they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catc hf ire.
In such situations, have the vehicle checked
and repaired immediately at aq ualified spe-
cialist workshop. If on continuin gy our jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aq ualified spe-
cialist workshop.
