Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of integrated
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 a manner
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
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire 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
consumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel
consumption.
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 service work 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 0001of its maximum engine speed.
R switch off the engine in stationary traffic. Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate 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. Product information
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz tests genuine parts as well as
conversion parts and accessories that have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed. Introduction

SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
001F SRS warning lamp
R Air bags
R The air bag control unit with crash sensors
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
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 G
WARNING
The SRS self-chec khas detected a
malfunction if the 001FSRS indicator lamp:
R does no tlight up at all
R does not go out after approximately four
seconds after the engine is started
R lights up after the engin eis started or while
the vehicle is in motion
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at a qualified
specialist workshop. SRS may otherwise fail
to activate when it is needed in the event of
an accident, which could lead to serious or
fatal injuries. SRS might also be activated
unexpectedly and unnecessarily, which could
also result in injury.
In addition, work carried out improperly on
SRS may render SRS inoperative or cause
unintended air bag deployment. Work on the
SRS system should only be carried out by
qualified specialist personnel. Consult a
qualified specialist workshop.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz Center for details. USA only: for further information,
contact our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372).
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 001F 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.
The SRS components are in operational
readiness when the 001FSRS warning lamp
goes out while the engine is running.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G

In very rare cases, Adaptive Highbea
mAssist
may fail too recognize other road users that
have lights, or may recognize them too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time. You can use this function to set the
headlamps to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel. Switching Adaptive Highbeam Assist

anew vehicle Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1,000miles (1,500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Avoid heavy loads, e.g .driving at full
throttle, during this period.
R Change gearing ood time, before the
tachometer needle is 0001of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain. After 1,000 miles (1,500 km), you can
increase the engine speed gradually and
accelerate the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
R
do not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R change gear in good time.
R ideally, drive for the first 1,000 miles
