Protection of the environment
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 amanner 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 condition sofyour 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 ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be carried out
at aq ualified 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 Ôof its maximum engine speed.
R switch off the engine in stationary traffic.
R monitor the vehicle's fuel consumption. H
Environmental note
Have defective high-voltage batteries dis-
posed of in an environmentally responsible
manner. Consult aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use aMercedes-Benz Service Centre for
this purpose. Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle to
dispose of it in an environmentally-responsible
manner in accordance with the European Union (EU) End of Life Vehicles Directive.
There is anetwork of return points and disas-
sembly plants available. You can return your
vehicle to these plants free of charge. This
makes avaluable contribution to the recycling
process and the conservation of resources.

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.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly–s ave fuelObserve 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. :

Driving tipsDriving and parking

The ECO display consist
softhree sections, with
an inner and outer area. The section scorre-
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 entir ejourney):
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 aresult of aparticu-
larly economical driving style. Dependin gonthe
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 aresult of eco-
nomical driving. Ahigher level indicates amore
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 afixed 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 factor sare not included in the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve ahigher 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 aconstant 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 ajourney. During
ap rolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 238).

WARNING
If you shift down on aslippery 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 aslippery road surface.
