Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of
comprehensive 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 are affected
by these 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 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 and
braking. 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.
R keep an eye on the vehicle's fuel
consumption. 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. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.

Introduction

SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
The 001E SRS warning lamp
R Air bags
R Air bag control unit (with crash sensors)
R Emergency Tensioning Devices
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
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident with a high rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at a qualified 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 001E 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 001ESRS warning lamp
goes out while the engine is running. There is a malfunction if:
R
the 001E SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 001ESRS
warning lamp does not go out after a few
seconds
R the engine is running and the 001ESRS
warning lamp lights up again
Safety guidelines for seat belts,
Emergency 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 supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling 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 a one-time-only basis. An air bag or ETD
that has deployed must 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 a crash 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 component
or 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

workshop. G
WARNING

substances. If batteries are swallowed, it can
result in severe health problems. There is a
risk of fatal injury.
Keep batteries out of the reach of children .If
a battery is swallowed, seek medical attention
immediately. 74
SmartKeyOpening and closing

The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. The
cornering light function can only be activated
when the low-beam headlamps are switched
on.
Active:
R
if you are driving at speeds below
25mph (40 km/h) and switch on the turn
signal or turn the steering wheel.
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel.
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signals or turn the steering wheel to the
straight-ahead position.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes. Adaptive Highbeam Assist
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognize
road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late.
In this or similars ituations, 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.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions. Adaptive Highbeam Assist is only an aid. You
are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured
General notes You can use this function to set the
headlamps to change betwee
nlow 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. 110
