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. Take-back of end-of-life vehicles
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. Genuine Mercedes-Benz parts

shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D.
If you deactivate manual gearshifting, the gears will be shifted automatically again. 150

Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Consumption can be significantly influ-
enced by your driving style. :

163Driving and parking Z

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R The outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds.
R The outer area empties and the
inner area is grey: sporty acceler-
ation. ;
Coasting
(evaluation of all decelera-
tion processes):
R The outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and early release of the accelerator.
The vehicle can coast without use
of the brakes.
R The outer area empties and the
inner area is grey: frequent heavy
braking. =
Constant
(continuous evaluation
over the entire journey):
R The outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and decelera-
tion.
R The outer area empties and the
inner area is grey: fluctuations in
speed. The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under
Bonus fr. start
Bonus fr. start does not
indicate a fixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included on the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation.
R drive the vehicle in drive program E(vehicles
with DYNAMIC SELECT switch)
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 226).

Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular164
