Protection of the environment
General notes
HEnvironmental 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 amanner
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:
Roperating conditionsofy our vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Rar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
startin gthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain asafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
HEnvironmental note
Have adefective high-voltage battery dis-
posed of in an environmentally-responsible
manner. Contact aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Center
for this purpose.
Environmental concerns and recom-
mendations
Wherever the operating instructions require you
to dispose of materials, first try to regenerate or
re-use them. Observe the relevant environmen-
tal rules and regulations when disposing of
materials. In this way you will help to protect the
environment.

156Driving tips
Driving an dparking

The ECO display consistsofthree sections, with
an inner and outer area. The section scorre-
spond to the following three categories:
:Acceleration (evaluation of all accel-
eration processes):
Rthe outer area fills up and the inner area lights up green: moderate
acceleration ,especially at higher
speeds
Rthe outer area empties and the
inner area is gray: sporty acceler-
ation
;Coasting (evaluation of all decelera-
tion processes):
Rthe 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.
Rthe outer area empties and the
inner area is gray: frequent heavy
braking
=Constant (continuous evaluation
over the entir ejourney):
Rthe outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
Rthe outer area empties and the
inner area is gray: 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
does not
indicate afixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumer
sswitched on
These factor sare not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achievingah igher value in the categories
"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive in drive program E.
On long journeys at aconstant speed, e.g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes 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. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform amanual rest
(
Ypage 206).
For further information on the ECO display,s ee

Ypage 205).
Braking
Important safety notes
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shiftin gtoa
lower gear in good time. This allows you to
take advantage of the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively.

AIRMATIC
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automaticallytoi mprove driving safety
and to reduce fuel consumption. There is also
the option to manuallya djust the vehicle level.
AIRMATIC consists of level setting, level control
and ADS (Adaptive Damping System).
The vehicle level can be set using the DYNAMIC
SELECT switch (
Ypage 139) or the level button
(Ypage 172). The setting always corresponds
to the last selected function.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is arisk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
iIf one of the doors is open, the vehicle is not
lowered.
Vehicle level
